According to DSM-5, it is rare for females to exhibit exhibitionistic disorder. While there have been suggestions that childhood sexual and emotional abuse, as well as hypersexuality, may increase the risk of developing exhibitionism, the causal relationship and specificity to this disorder are uncertain.

Paraphilias are intense and persistent sexual interests other than sexual interest in genital stimulation of preparatory fondling with phenotypically normal, physically mature, consenting human partners. They are divided into those relating to erotic activity and those relating to erotic target. In order to become a disorder, paraphilias must be associated with distress of impairment to the individual of with harm to others. The DSM-5 lists 8 recognised paraphilic disorder but acknowledges that there are many more. Treatment modalities for the paraphilias have limited scientific evidence to support their use. Psychological therapy (especially CBT) is often used (with extremely variable results). Pharmacological options include SSRI, Naltrexone, Antipsychotics, GnRH agonists, and Anti-androgens and progestational drugs (e.g. cyproterone acetate).

According to ICD-11, the bodily symptoms that are most frequently reported by children and adolescents are gastrointestinal symptoms that occur repeatedly (such as abdominal pain and nausea), fatigue, headaches, and musculoskeletal pain. Typically, children tend to experience one recurring symptom rather than multiple bodily symptoms.

Somatoform and dissociative disorders are two groups of psychiatric disorders that are characterized by physical symptoms and disruptions in the normal integration of identity, sensations, perceptions, affects, thoughts, memories, control over bodily movements, of behavior. Somatoform disorders are characterized by physical symptoms that are presumed to have a psychiatric origin, while dissociative disorders are characterized by the loss of integration between memories, identity, immediate sensations, and control of bodily movements. The ICD-11 lists two main types of somatoform disorders: bodily distress disorder and body integrity dysphoria. Dissociative disorders include dissociative neurological symptom disorder, dissociative amnesia, trance disorder, possession trance disorder, dissociative identity disorder, partial dissociative identity disorder, depersonalization-derealization disorder, and other specified dissociative disorders. The symptoms of these disorders result in significant impairment in personal, family, social, educational, occupational, of other important areas of functioning. Diagnosis of these disorders involves a thorough evaluation of the individual’s symptoms and medical history, as well as ruling out other possible causes of the symptoms.

The search ‘Psychosis AND (cannabis AND sexual abuse)’ would also return citations with all three terms, but it allows for the possibility of citations that include both cannabis and sexual abuse, but not necessarily psychosis.

Evidence-based medicine involves four basic steps: developing a focused clinical question, searching for the best evidence, critically appraising the evidence, and applying the evidence and evaluating the outcome. When developing a question, it is important to understand the difference between background and foreground questions. Background questions are general questions about conditions, illnesses, syndromes, and pathophysiology, while foreground questions are more often about issues of care. The PICO system is often used to define the components of a foreground question: patient group of interest, intervention of interest, comparison, and primary outcome.

When searching for evidence, it is important to have a basic understanding of the types of evidence and sources of information. Scientific literature is divided into two basic categories: primary (empirical research) and secondary (interpretation and analysis of primary sources). Unfiltered sources are large databases of articles that have not been pre-screened for quality, while filtered resources summarize and appraise evidence from several studies.

There are several databases and search engines that can be used to search for evidence, including Medline and PubMed, Embase, the Cochrane Library, PsycINFO, CINAHL, and OpenGrey. Boolean logic can be used to combine search terms in PubMed, and phrase searching and truncation can also be used. Medical Subject Headings (MeSH) are used by indexers to describe articles for MEDLINE records, and the MeSH Database is like a thesaurus that enables exploration of this vocabulary.

Bipolar Disorder: Diagnosis and Management

Bipolar disorder is a lifelong condition characterized by episodes of mania or hypomania and episodes of depressed mood. The peak age of onset is 15-19 years, and the lifetime prevalence of bipolar I disorders is estimated to be around 2.1%. The diagnosis of bipolar disorder is based on the presence of manic or hypomanic episodes, which are characterized by elevated of expansive mood, rapid speech, and increased activity of energy. Psychotic symptoms, such as delusions and hallucinations, may also be present.

Bipolar depression differs from unipolar depression in several ways, including more rapid onset, more frequent episodes, and shorter duration. Rapid cycling is a qualifier that can be applied to bipolar I of bipolar II disorder and is defined as the presence of at least four mood episodes in the previous 12 months that meet the criteria for a manic, hypomanic, of major depressive episode.

The management of bipolar disorder involves acute and long-term interventions. Acute management of mania or hypomania may involve stopping antidepressants and offering antipsychotics of mood stabilizers. Long-term management may involve psychological interventions and pharmacological treatments such as lithium, valproate, of olanzapine.

It is important to note that valproate should not be offered to women of girls of childbearing potential for long-term bipolar disorder unless other options are ineffective of not tolerated and a pregnancy prevention program is in place. Aripiprazole is recommended as an option for treating moderate to severe manic episodes in adolescents with bipolar I disorder.

Overall, the diagnosis and management of bipolar disorder require a comprehensive approach that takes into account the individual’s symptoms, history, and preferences.

Clozapine is an effective antipsychotic drug used in the management of treatment-resistant schizophrenia (TRS). It was reintroduced in the 1990s with mandatory blood monitoring due to the risk of agranulocyte

Chlorpromazine: Photosensitivity Reactions and Patient Precautions

Chlorpromazine, the first drug used for psychosis, is a common topic in exams. However, it is important to note that photosensitivity reactions are a known side effect of its use. Patients taking chlorpromazine should be informed of this and advised to take necessary precautions. Proper education and awareness can help prevent potential harm from photosensitivity reactions.

Fonagy and Bateman – Mentalisation-Based Treatment

Mentalisation-Based Treatment (MBT) was developed by Peter Fonagy and Anthony Bateman in the 1990s. It is a psychodynamic therapy that focuses on improving the patient’s ability to mentalise, which is the capacity to understand one’s own and others’ mental states. MBT is primarily used to treat borderline personality disorder, but it has also been used to treat other mental health conditions.

Fonagy and Bateman work on MBT was influenced by their research on attachment theory and the importance of early relationships in shaping mentalisation abilities. They believed that individuals with borderline personality disorder have difficulties with mentalisation due to early attachment disruptions, and that MBT could help them develop more stable and secure relationships.

MBT is typically delivered in a group of individual format, and it involves a combination of psychoeducation, cognitive-behavioral techniques, and psychodynamic interventions. The therapist helps the patient to identify and reflect on their thoughts, feelings, and behaviors, and to understand how these are influenced by their past experiences and relationships. The therapist also helps the patient to develop more adaptive coping strategies and to improve their interpersonal skills.

Overall, Fonagy and Bateman work on MBT has contributed to the development of psychodynamic therapies that are more focused on specific treatment goals and evidence-based practices.

Understanding Learning Disabilities: Key Terms to Know

Learning disabilities can be complex and challenging to understand. To help make sense of this topic, it’s important to be familiar with some key terms. Two important terms to know are impairments and disability.

Impairments refer to problems in body function and structure, such as significant deviation of loss. This can include difficulties with vision, hearing, mobility, of cognitive functioning. Impairments can impact a person’s ability to learn and participate in daily activities.

Disability is an umbrella term that encompasses impairments, activity limitations, and participation restrictions. It refers to the negative aspects of the interaction between a person’s health condition(s) and their contextual factors, including environmental and personal factors. For example, a person with a learning disability may experience difficulty with reading, writing, of math, which can impact their ability to participate fully in school of work.

Understanding these terms can help individuals better understand the challenges faced by those with learning disabilities and work towards creating more inclusive and supportive environments.

Methods of Economic Evaluation

There are four main methods of economic evaluation: cost-effectiveness analysis (CEA), cost-benefit analysis (CBA), cost-utility analysis (CUA), and cost-minimisation analysis (CMA). While all four methods capture costs, they differ in how they assess health effects.

Cost-effectiveness analysis (CEA) compares interventions by relating costs to a single clinical measure of effectiveness, such as symptom reduction of improvement in activities of daily living. The cost-effectiveness ratio is calculated as total cost divided by units of effectiveness. CEA is typically used when CBA cannot be performed due to the inability to monetise benefits.

Cost-benefit analysis (CBA) measures all costs and benefits of an intervention in monetary terms to establish which alternative has the greatest net benefit. CBA requires that all consequences of an intervention, such as life-years saved, treatment side-effects, symptom relief, disability, pain, and discomfort, are allocated a monetary value. CBA is rarely used in mental health service evaluation due to the difficulty in converting benefits from mental health programmes into monetary values.

Cost-utility analysis (CUA) is a special form of CEA in which health benefits/outcomes are measured in broader, more generic ways, enabling comparisons between treatments for different diseases and conditions. Multidimensional health outcomes are measured by a single preference- of utility-based index such as the Quality-Adjusted-Life-Years (QALY). QALYs are a composite measure of gains in life expectancy and health-related quality of life. CUA allows for comparisons across treatments for different conditions.

Cost-minimisation analysis (CMA) is an economic evaluation in which the consequences of competing interventions are the same, and only inputs, i.e. costs, are taken into consideration. The aim is to decide the least costly way of achieving the same outcome.

Costs in Economic Evaluation Studies

There are three main types of costs in economic evaluation studies: direct, indirect, and intangible. Direct costs are associated directly with the healthcare intervention, such as staff time, medical supplies, cost of travel for the patient, childcare costs for the patient, and costs falling on other social sectors such as domestic help from social services. Indirect costs are incurred by the reduced productivity of the patient, such as time off work, reduced work productivity, and time spent caring for the patient by relatives. Intangible costs are difficult to measure, such as pain of suffering on the part of the patient.

Understanding Stats Variables

Variables are characteristics, numbers, of quantities that can be measured of counted. They are also known as data items. Examples of variables include age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour, and vehicle type. The value of a variable may vary between data units in a population. In a typical study, there are three main variables: independent, dependent, and controlled variables.

The independent variable is something that the researcher purposely changes during the investigation. The dependent variable is the one that is observed and changes in response to the independent variable. Controlled variables are those that are not changed during the experiment. Dependent variables are affected by independent variables but not by controlled variables, as these do not vary throughout the study.

For instance, a researcher wants to test the effectiveness of a new weight loss medication. Participants are divided into three groups, with the first group receiving a placebo (0mg dosage), the second group a 10 mg dose, and the third group a 40 mg dose. After six months, the participants’ weights are measured. In this case, the independent variable is the dosage of the medication, as that is what is being manipulated. The dependent variable is the weight, as that is what is being measured.

It is important to take clozapine levels as trough samples, which means they should be taken 11-13 hours after the last dose. Samples taken outside of this time frame may produce inaccurate results. If the levels are taken too early (before 11 hours), the clozapine levels may be artificially high, resulting in high ratios. Conversely, if the levels are taken too late (after 11 hours), the clozapine levels may be artificially low, resulting in low ratios.

Clozapine is an effective antipsychotic drug used in the management of treatment-resistant schizophrenia (TRS). It was reintroduced in the 1990s with mandatory blood monitoring due to the risk of agranulocyte

The use of tamoxifen should not be combined with paroxetine and fluoxetine as it may decrease its effectiveness.

Tamoxifen and Antidepressant Interactions

Tamoxifen is a medication used to treat breast cancer by reducing relapse rates and increasing overall survival. It works by antagonizing estrogen in the breast, with its anti-estrogen affinity depending on its primary metabolite, endoxifen. However, tamoxifen is metabolized to endoxifen through the liver enzyme CYP2D6, and any drug that inhibits this enzyme can reduce the conversion of tamoxifen to endoxifen.

Women taking tamoxifen for breast cancer treatment of prevention may also take antidepressants for psychiatric disorders of hot flushes. Some antidepressants have been found to inhibit the metabolism of tamoxifen to its more active metabolites by the CYP2D6 enzyme, thereby decreasing its anticancer effect. Strong CYP2D6 inhibitors include paroxetine, fluoxetine, bupropion, and duloxetine, while moderate inhibitors include sertraline, escitalopram, and doxepin, and venlafaxine is a weak inhibitor.

Therefore, it is important for healthcare providers to consider potential drug interactions when prescribing antidepressants to women taking tamoxifen for breast cancer treatment of prevention.

Both the NICE Guidelines and the Maudsley Guidelines suggest using SSRIs as the primary treatment for OCD, with the Maudsley also mentioning clomipramine as an option. However, the Maudsley advises trying SSRIs first due to potential tolerability concerns with clomipramine. It is recommended to follow both sets of guidelines consistently whenever feasible.

Maudsley Guidelines

First choice: SSRI of clomipramine (SSRI preferred due to tolerability issues with clomipramine)

Second line:

– SSRI + antipsychotic
– Citalopram + clomipramine
– Acetylcysteine + (SSRI of clomipramine)
– Lamotrigine + SSRI
– Topiramate + SSRI

Due to the patient’s pregnancy, mood stabilisers cannot be used as a traditional treatment for their mixed affective state, which presents symptoms of both mania and depression. Instead, an antipsychotic is the preferred course of action.

Bipolar Disorder in Women of Childbearing Potential

Prophylaxis is recommended for women with bipolar disorder, as postpartum relapse rates are high. Women without prophylactic pharmacotherapy during pregnancy have a postpartum relapse rate of 66%, compared to 23% for women with prophylaxis. Antipsychotics are recommended for pregnant women with bipolar disorder, according to NICE Guidelines (CG192) and the Maudsley. Women taking valproate, lithium, carbamazepine, of lamotrigine should discontinue treatment and start an antipsychotic, especially if taking valproate. If a woman with bipolar disorder is taking lithium and becomes pregnant, she should gradually stop lithium over a 4 week period and start an antipsychotic. If this is not possible, lithium levels must be taken regularly, and the dose adjusted accordingly. For acute mania, an antipsychotic should be considered. For mild depressive symptoms, self-help approaches, brief psychological interventions, and antidepressant medication can be considered. For moderate to severe depressive symptoms, psychological treatment (CBT) for moderate depression and combined medication and structured psychological interventions for severe depression should be considered.

Classification of Intellectual Disability

Intellectual disability affects approximately 2% of the general population, with an estimated 828,000 adults aged 18 of older affected in England alone. Those with an IQ below 70 are considered to have an intellectual disability, with the average IQ being 100. The severity of intellectual disability is categorized based on IQ scores, with mild intellectual disability being the most common (85% of cases) and profound intellectual disability being the least common (1-2% of cases). People with intellectual disability may require varying levels of support in their daily lives, depending on their individual needs. It is important to use the preferred term ‘people with intellectual disability’ when referring to individuals with this condition.

Drug Screening

Drug testing can be conducted through various methods, but urinalysis is the most common. Urine drug tests can be either screening of confirmatory. Screening tests use enzymatic immunoassays to detect drug metabolites of classes of drug metabolites in the urine. However, these tests have limitations, such as false positives due to cross-reactivity. Therefore, any positive test should be confirmed through gas chromatography of mass spectrometry.

People may try to manipulate drug testing procedures by adulterating the sample. Normal urine parameters, such as temperature, specific gravity, and pH, can assist in detecting adulterated samples. Adulterants include household items like vinegar, detergent, and ammonia, as well as commercially available products. Diluted urine may also yield false negatives.

Detection times vary from person to person, and the approximate drug detection time in urine can be found in a table provided by Nelson (2016). False positives can occur due to cross-reactivity, as illustrated by Moeller (2017). Clinicians should be aware of the limitations of urine drug tests and the potential for manipulation.

To prevent bias in the study, the researchers are implementing patient blinding to prevent performance bias, as knowledge of whether they are taking venlafaxine of a placebo, of which arm of the study they are in, could impact the patient’s behavior. Additionally, investigators must also be blinded to avoid measurement bias.

Raising the threshold for a positive test outcome will result in a reduction in the number of incorrect positive results, leading to an improvement in specificity.

Clinical tests are used to determine the presence of absence of a disease of condition. To interpret test results, it is important to have a working knowledge of statistics used to describe them. Two by two tables are commonly used to calculate test statistics such as sensitivity and specificity. Sensitivity refers to the proportion of people with a condition that the test correctly identifies, while specificity refers to the proportion of people without a condition that the test correctly identifies. Accuracy tells us how closely a test measures to its true value, while predictive values help us understand the likelihood of having a disease based on a positive of negative test result. Likelihood ratios combine sensitivity and specificity into a single figure that can refine our estimation of the probability of a disease being present. Pre and post-test odds and probabilities can also be calculated to better understand the likelihood of having a disease before and after a test is carried out. Fagan’s nomogram is a useful tool for calculating post-test probabilities.

The sudden appearance of symptoms without a preceding prodrome indicates an acute and temporary psychotic disorder, rather than the milder experiences observed in schizotypal disorder.

– Schizophrenia and other primary psychotic disorders are characterized by impairments in reality testing and alterations in behavior.
– Schizophrenia is a chronic mental health disorder with symptoms including delusions, hallucinations, disorganized speech of behavior, and impaired cognitive ability.
– The essential features of schizophrenia include persistent delusions, persistent hallucinations, disorganized thinking, experiences of influence, passivity of control, negative symptoms, grossly disorganized behavior, and psychomotor disturbances.
– Schizoaffective disorder is diagnosed when all diagnostic requirements for schizophrenia are met concurrently with mood symptoms that meet the diagnostic requirements of a moderate or severe depressive episode, a manic episode, of a mixed episode.
– Schizotypal disorder is an enduring pattern of unusual speech, perceptions, beliefs, and behaviors that are not of sufficient intensity of duration to meet the diagnostic requirements of schizophrenia, schizoaffective disorder, of delusional disorder.
– Acute and transient psychotic disorder is characterized by an acute onset of psychotic symptoms, which can include delusions, hallucinations, disorganized thinking, of experiences of influence, passivity of control, that emerge without a prodrome, progressing from a non-psychotic state to a clearly psychotic state within 2 weeks.
– Delusional disorder is diagnosed when there is a presence of a delusion of set of related delusions, typically persisting for at least 3 months and often much longer, in the absence of a depressive, manic, of mixed episode.

Aromatherapy is a form of complementary therapy that involves the use of essential oils, such as Melissa balm and lavender, which can be applied directly to the skin, heated in a burner, of added to a bath. The benefits of aromatherapy are believed to be primarily due to sensory stimulation, and it can be used in a variety of clinical settings. In fact, 11 randomized controlled trials have shown that aromatherapy is effective in managing the Behavioral and Psychological Symptoms of Dementia (BPSD). As research continues on non-pharmacological interventions for BPSD, it is important to consider the potential benefits of aromatherapy, as well as other interventions such as doll therapy, dance/movement therapy, light therapy, and animal-assisted therapy.

The rate is considerably greater than that of adults who are of working age.

Suicide Rates Following Self-Harm

Most individuals who engage in self-harm do not go on to commit suicide, which makes risk assessment challenging. A study conducted in the UK in 2015 by Hawton found that 0.5% of individuals died by suicide in the first year following self-harm, with a higher rate among males (0.82%) than females (0.27%). Over the two-year period following self-harm, 1.6% died by suicide, with more occurrences in the second year. Interestingly, a study by Murphy in 2012 found that the rate of suicide following self-harm was higher in the elderly (those over 60), with a rate of 1.5 suicides in the first 12 months. The only significant risk factor for suicide following self-harm in this study was the use of a violent method in the initial episode.

Evidence-based medicine involves four basic steps: developing a focused clinical question, searching for the best evidence, critically appraising the evidence, and applying the evidence and evaluating the outcome. When developing a question, it is important to understand the difference between background and foreground questions. Background questions are general questions about conditions, illnesses, syndromes, and pathophysiology, while foreground questions are more often about issues of care. The PICO system is often used to define the components of a foreground question: patient group of interest, intervention of interest, comparison, and primary outcome.

When searching for evidence, it is important to have a basic understanding of the types of evidence and sources of information. Scientific literature is divided into two basic categories: primary (empirical research) and secondary (interpretation and analysis of primary sources). Unfiltered sources are large databases of articles that have not been pre-screened for quality, while filtered resources summarize and appraise evidence from several studies.

There are several databases and search engines that can be used to search for evidence, including Medline and PubMed, Embase, the Cochrane Library, PsycINFO, CINAHL, and OpenGrey. Boolean logic can be used to combine search terms in PubMed, and phrase searching and truncation can also be used. Medical Subject Headings (MeSH) are used by indexers to describe articles for MEDLINE records, and the MeSH Database is like a thesaurus that enables exploration of this vocabulary.

Psychotic Depression

Psychotic depression is a type of depression that is characterized by the presence of delusions and/of hallucinations in addition to depressive symptoms. This condition is often accompanied by severe anhedonia, loss of interest, and psychomotor retardation. People with psychotic depression are tormented by hallucinations and delusions with typical themes of worthlessness, guilt, disease, of impending disaster. This condition affects approximately 14.7-18.5% of depressed patients and is estimated to affect around 0.4% of community adult samples, with a higher prevalence in the elderly community at around 1.4-3.0%. People with psychotic depression are at a higher risk of attempting and completing suicide than those with non-psychotic depression.

Diagnosis

Psychotic depression is currently classified as a subtype of depression in both the ICD-11 and the DSM-5. The main difference between the two is that in the ICD-11, the depressive episode must be moderate of severe to qualify for a diagnosis of depressive episode with psychotic symptoms, whereas in the DSM-5, the diagnosis can be applied to any severity of depressive illness.

Treatment

The recommended treatment for psychotic depression is tricyclics as first-line treatment, with antipsychotic augmentation. Second-line treatment includes SSRI/SNRI. Augmentation of antidepressant with olanzapine or quetiapine is recommended. The optimum dose and duration of antipsychotic augmentation are unknown. If one treatment is to be stopped during the maintenance phase, then this should be the antipsychotic. ECT should be considered where a rapid response is required of where other treatments have failed. According to NICE (ng222), combination treatment with antidepressant medication and antipsychotic medication (such as olanzapine or quetiapine) should be considered for people with depression with psychotic symptoms. If a person with depression with psychotic symptoms does not wish to take antipsychotic medication in addition to an antidepressant, then treat with an antidepressant alone.

Neo-Freudians were therapists who developed their own theories while still retaining core Freudian components. Some important neo-Freudians include Alfred Adler, Carl Jung, Erik Erickson, Harry Stack Sullivan, Wilfred Bion, John Bowlby, Anna Freud, Otto Kernberg, Margaret Mahler, and Donald Winnicott. Each of these individuals contributed unique ideas to the field of psychology. For example, Carl Jung introduced the concept of the persona and differentiated between the personal and collective unconscious, while Erik Erickson is known for his stages of psychosocial development. Margaret Mahler developed theories on child development, including the three main phases of autistic, symbiotic, and separation-individuation. Donald Winnicott introduced the concept of the transitional object and the good enough mother. Overall, neo-Freudians expanded upon Freud’s ideas and helped to shape modern psychotherapy.

The Delphi Method: A Widely Used Technique for Achieving Convergence of Opinion

The Delphi method is a well-established technique for soliciting expert opinions on real-world knowledge within specific topic areas. The process involves multiple rounds of questionnaires, with each round building on the previous one to achieve convergence of opinion among the participants. However, there are potential issues with the Delphi method, such as the time-consuming nature of the process, low response rates, and the potential for investigators to influence the opinions of the participants. Despite these challenges, the Delphi method remains a valuable tool for generating consensus among experts in various fields.

Conflict can serve as a valuable tool in a therapeutic community, as it can facilitate group sessions. Honesty and open communication are encouraged among members, allowing for constructive feedback.

Therapeutic Communities: A Brief Overview

Therapeutic communities have been a popular form of treatment since the 1960s, with Tom Maine and Maxwell Jones being two of the most well-known names associated with this approach. In these communities, patients reside with staff and engage in group therapy sessions where they discuss community issues. This allows therapists to guide the group therapy process.

Therapeutic communities are based on four core values: democratisation, permissiveness, communalism, and reality-confrontation. The first value emphasizes that all members of the community, including staff, should be considered equal. The second value stresses the importance of tolerance towards others’ behavior. The third value encourages members to socialize and share facilities, rather than isolating themselves in their rooms. Finally, the fourth value involves continuously providing feedback to members on their comments and behaviors to prevent them from distorting reality.

Overall, therapeutic communities offer a unique approach to treatment that emphasizes community and group therapy. By promoting these core values, therapeutic communities aim to create a supportive and healing environment for all members.

Clozapine is an effective antipsychotic drug used in the management of treatment-resistant schizophrenia (TRS). It was reintroduced in the 1990s with mandatory blood monitoring due to the risk of agranulocyte

Aetiology of Post Traumatic Stress Disorder

Post traumatic stress disorder (PTSD) is a mental health condition that can develop after experiencing of witnessing a traumatic event. The aetiology of PTSD is complex and involves various factors, including changes in cortisol levels and alterations in brain structures.

Studies have shown that individuals with PTSD have lower ambient cortisol levels than normal, which has been attributed to chronic adrenal exhaustion resulting from the inhibition of the hypothalamic-pituitary-adrenal (HPA) axis by persistent severe anxiety. This suggests that the stress response system in individuals with PTSD may be dysregulated, leading to abnormal cortisol levels.

Two brain structures, the amygdala and the hippocampus, have also been implicated in the aetiology of PTSD. The amygdala is responsible for processing emotions, particularly fear, and is hyperactive in individuals with PTSD. This hyperactivity may contribute to the intense fear and anxiety experienced by individuals with PTSD. The hippocampus, which is involved in memory processing, is also affected in individuals with PTSD. Studies have shown that the hippocampus is smaller in individuals with PTSD, which may contribute to the difficulty in recalling traumatic events and the intrusive memories associated with PTSD.

Overall, the aetiology of PTSD is multifactorial and involves changes in cortisol levels and alterations in brain structures, particularly the amygdala and hippocampus. Understanding these underlying mechanisms is crucial for developing effective treatments for individuals with PTSD.

New Psychoactive Substances, previously known as ‘legal highs’, are synthetic compounds designed to mimic the effects of traditional illicit drugs. They became popular due to their ability to avoid legislative control, but the introduction of the Psychoactive Substances Act 2016 changed this. There is no standard for clinical classification, but some common legal highs include Mephedrone, Piperazines, GBL, Synthetic cannabinoids, and Benzofuran compounds. These substances have effects similar to ecstasy, amphetamines, and cannabis, and are classified as either Class B of Class C drugs in the UK.
