The LUNSERS is a self-administered rating scale consisting of 51 items used to detect side effects caused by antipsychotic medication. It comprises 41 established side effects of neuroleptics and 10 additional items that are not known to be side effects of such medication, such as hair loss and chilblains, to validate the results. The scale’s validity and reliability were assessed in a sample of 50 male and female patients with an average age of 46 years and 16 years of antipsychotic use, as well as a group of 50 healthy controls, with promising outcomes. Furthermore, the LUNSERS’ validity was compared to that of the UKU, which is the gold standard and takes approximately 60 minutes to complete.

In psychiatry, various questionnaires and interviews are used to assess different conditions and areas. It is important for candidates to know whether certain assessment tools are self-rated of require clinical assistance. The table provided by the college lists some of the commonly used assessment tools and indicates whether they are self-rated of clinician-rated. For example, the HAMD and MADRS are clinician-rated scales used to assess the severity of depression, while the GDS is a self-rated scale used to screen for depression in the elderly. The YMRS is a clinician-rated scale used to assess the severity of mania in patients with bipolar disorder, while the Y-BOCS is used to measure both the severity of OCD and the response to treatment. The GAF provides a single measure of global functioning, while the CGI requires the clinician to rate the severity of the patient’s illness at the time of assessment. The CAMDEX is a tool developed to assist in the early diagnosis and measurement of dementia in the elderly.

The four moral principles are a useful tool in clinical practice. For instance, if a patient arrives in critical condition after a car accident and is unable to provide informed consent, the principle of beneficence requires healthcare professionals to prioritize treatment for the patient. The principle of justice may also be considered if there are many patients in need of care of if the treatment is expensive of scarce, potentially depriving others of medical attention. Non-maleficence is relevant if the treatment is likely to cause more harm than good. Respect for autonomy is important if the patient has previously expressed a desire to decline treatment in such circumstances.

Atypical depression can often be mistaken for a personality disorder due to its symptoms, which include sensitivity to rejection, low but reactive mood, some ability to experience pleasure (though not to normal levels), hyperphagia with at least 3 kg of weight gain in three months, hypersomnia, and a feeling of heaviness in the limbs. However, the key to diagnosing atypical depression is a change in function. It is important to gather collateral history to determine if there is a lifelong pattern of problems that have been exacerbated of if the break-up is due to the depression and the resulting sensitivity to rejection. The preferred treatment for atypical depression is MAOIs.

Mental Age and IQ

The concept of mental age (MA) was introduced by Alfred Binet in 1905. It involves administering a series of tests to a person of child, which are then ranked according to the age at which people are expected to complete them. The mental age can be used to calculate the intelligence quotient (IQ) using the formula: IQ = MA/CA x 100, where CA is the chronological age. An IQ of 100 indicates that the mental and chronological ages are equal. IQ tends to remain stable throughout life. The Stanford-Binet test was the first IQ test, while the WAIS-IV (Wechsler Adult Intelligence Scale) is the most commonly used IQ test today.

A pituitary adenoma can cause compression of the optic chiasm, resulting in a bitemporal hemianopia. Other tumors, such as craniopharyngiomas, meningiomas, of gliomas, can also cause this type of visual field defect. Cerebellopontine angle tumors typically present with symptoms related to the facial, vestibulocochlear, and trigeminal nerves. A cerebrovascular event in the occipital cortex can cause visual loss, usually in the form of a homonymous hemianopia. Diabetes mellitus can cause various visual defects, including diabetic retinopathy, retinal hemorrhages of detachment, and oculomotor nerve palsy. Oculomotor nerve palsies can be caused by a variety of conditions, such as vascular events, diabetic neuropathy, intracranial aneurysms, syphilis, of raised intracranial pressure. Symptoms include ptosis, diplopia, and possible mydriasis. Laser treatment for diabetic retinopathy is unlikely to cause a well-defined homonymous hemianopia.

Neurotransmitters are substances used by neurons to communicate with each other and with target tissues. They are synthesized and released from nerve endings into the synaptic cleft, where they bind to receptor proteins in the cellular membrane of the target tissue. Neurotransmitters can be classified into different types, including small molecules (such as acetylcholine, dopamine, norepinephrine, serotonin, and GABA) and large molecules (such as neuropeptides). They can also be classified as excitatory or inhibitory. Receptors can be ionotropic or metabotropic, and the effects of neurotransmitters can be fast of slow. Some important neurotransmitters include acetylcholine, dopamine, GABA, norepinephrine, and serotonin. Each neurotransmitter has a specific synthesis, breakdown, and receptor type. Understanding neurotransmitters is important for understanding the function of the nervous system and for developing treatments for neurological and psychiatric disorders.

Historical Classification of Schizophrenia

The classification of schizophrenia has evolved over time, with various individuals contributing to its development. In 1801, Phillippe Pinel used the term ‘demencé’ to describe the loss of mental abilities in chronically ill patients. Benedict Morel coined the term ‘demencé precocé’ in 1852 to describe young patients with premature dementia. Kahlbaum was the first to describe ‘paraphrenia hebetica’ in the 1860s, which was later elaborated as ‘hebephrenia’ by Hecker in 1871.

In 1893, Emil Kraepelin used the term dementia praecox to describe the condition, emphasizing the importance of delusions, hallucinations, impaired attention, thought incoherence, stereotyped movements and expressions, deterioration of emotional life, and a loss of drive as key symptoms. In 1908, Eugen Bleuler coined the term ‘schizophrenia’ to replace dementia praecox, denoting ‘a splitting of the psychic functions.’ Bleuler expanded the concept to include presentations that did not include a ‘terminal state.’

Bleuler introduced a distinction between basic and accessory symptoms and primary and secondary symptoms. Basic symptoms are necessarily present in any case of schizophrenia, while accessory symptoms may of may not occur. The fundamental features of schizophrenia were loosening of associations, disturbances of affectivity, ambivalence, and autism. The alteration of associations is the only symptom that Bleuler regarded as both basic and primary, and can thus be described as the core disturbance in the Bleulerian conception of schizophrenia.

In 1939, Langfeldt introduced the term ‘schizophreniform psychosis’ to describe patients with Bleulerian schizophrenia who did not follow a progressively deteriorating course. In the 1960s, Rado/Meehl introduced the term ‘schizotypy’ to recognize the concept of a continuum of spectrum of schizophrenia-related phenotypes. In the 1980s, Crow proposed a subclassification of schizophrenia, dividing patients into types I and II. Type I patients present with positive symptoms such as delusions and hallucinations, while type II patients present with negative symptoms such as affective flattening and poverty of speech.

Citalopram can moderately prolong QTc (>10 msec), while aripiprazole and paliperidone have no effect. Haloperidol and pimozide have a high effect, and quetiapine and amisulpride have a moderate effect. Clozapine, risperidone, and olanzapine have a low effect (<10 msec prolongation). Lamotrigine, mirtazapine, and SSRIs (excluding citalopram) do not have an effect on QTc interval.

Attachment theory is a framework that emphasizes the importance of secure emotional bonds and resources in shaping an individual’s development and behavior. It highlights the significance of early relationships and experiences in shaping one’s sense of security and ability to form healthy relationships later in life.

The man’s mother’s stance against violence prevented him from acting aggressively towards his father. Instead, he found an outlet for his aggression through martial arts, which was deemed socially acceptable. His success as a champion suggests that he sublimated his aggression into a positive pursuit, rather than displacing it onto others, which is a less mature defense mechanism. There is no indication that he repressed his feelings towards his father, as he was able to channel his aggression in a constructive manner.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

Serotonin (5-hydroxytryptamine, 5-HT) receptors are primarily G protein receptors, except for 5-HT3, which is a ligand-gated receptor. It is important to remember that 5-HT3 is most commonly associated with nausea. Additionally, 5-HT7 is linked to circadian rhythms. The stimulation of 5-HT2 receptors is believed to be responsible for the side effects of insomnia, agitation, and sexual dysfunction that are associated with the use of selective serotonin reuptake inhibitors (SSRIs).

Solanezumab is a type of humanised monoclonal antibody that can bind to the central region of β-amyloid, which is believed to prevent the formation of plaques. However, current research has not yet determined whether this drug is effective in treating Alzheimer’s dementia.

Carbimazole is a medication that is commonly used to treat hyperthyroidism, a condition in which the thyroid gland produces too much thyroid hormone.

Levomilnacipran is a newly approved drug by the FDA that is used to treat major depressive disorder.

Pantoprazole is a type of proton pump inhibitor that is used to treat acid reflux disease, a condition in which stomach acid flows back into the esophagus.

Zubsolv is a recently approved drug by the FDA that is used for the maintenance treatment of opioid dependence.

Alzheimer’s disease often results in the shrinkage of the hippocampus, which is a component of the limbic system and is responsible for the formation and retention of long-term memories.

Alzheimer’s disease is characterized by both macroscopic and microscopic changes in the brain. Macroscopic changes include cortical atrophy, ventricular dilation, and depigmentation of the locus coeruleus. Microscopic changes include the presence of senile plaques, neurofibrillary tangles, gliosis, degeneration of the nucleus of Meynert, and Hirano bodies. Senile plaques are extracellular deposits of beta amyloid in the gray matter of the brain, while neurofibrillary tangles are intracellular inclusion bodies that consist primarily of hyperphosphorylated tau. Gliosis is marked by increases in activated microglia and reactive astrocytes near the sites of amyloid plaques. The nucleus of Meynert degenerates in Alzheimer’s, resulting in a decrease in acetylcholine in the brain. Hirano bodies are actin-rich, eosinophilic intracytoplasmic inclusions which have a highly characteristic crystalloid fine structure and are regarded as a nonspecific manifestation of neuronal degeneration. These changes in the brain contribute to the cognitive decline and memory loss seen in Alzheimer’s disease.

Mutations are changes in the DNA of a cell. There are different types of mutations, including missense mutations, nonsense mutations, point mutations, frameshift mutations, and silent mutations. Missense mutations alter the codon, resulting in a different amino acid in the protein product. Nonsense mutations change a codon that specifies an amino acid to a stop codon, which prematurely stops the translation process. Point mutations involve a single change in one base of the gene sequence. Frameshift mutations occur when a number of nucleotides are inserted of deleted, causing a shift in the sequence and a different translation than the original. Silent mutations code for the same amino acid. Stop codons are nucleotide triplets that signal the end of the translation process. There are three types of stop codons: TAA, TAG, and TGA. When these codons undergo DNA transcription, they change to UAA, UAG, and UGA, which are the stop codons found in RNA molecules.

Cerebellar signs are evident in cases of lithium toxicity, which can manifest as slurred speech, a broad-based gait, and an intention tremor. The latter is characterized by a coarse appearance and a frequency of 2-3Hz (equivalent to 2 waves per second).

Types of Tremor

Essential Tremor

Otherwise known as benign essential tremor, this is the most common type of tremor. It is not associated with any underlying pathology. It usually begins in the 40’s, affects mainly the hands, and is slowly progressive. It tends to worsen with heightened emotion. It usually presents with unilateral upper limb involvement then progresses to both limbs.

Parkinsonian Tremor

This tremor is associated with Parkinson’s disease. It is classically described as ‘pill rolling’ due to the characteristic appearance of the fingers.

Cerebellar Tremor

Otherwise known as an intention tremor. This is a slow, coarse tremor which gets worse with purposeful movement. This is seen in lithium toxicity (note that the tremor seen as a side effect of long term lithium is fine and classed as physiological).

Psychogenic Tremor

Also known as a hysterical tremor. This type of tremor tends to appear and disappear suddenly and is hard to characterise due to its changeable nature. It tends to improve with distraction.

Physiologic Tremor

This is a very-low-amplitude fine tremor that is barely visible to the naked eye. It is present in every normal person while maintaining a posture of movement. It becomes enhanced and visible in many conditions such as anxiety, hyperthyroidism, alcohol withdrawal, and as drug induced side effects.

It is useful to have a basic idea about the frequencies of different types of tremor.

Type of Tremor Frequency

Intention 2-3Hz

Parkinsonian 5Hz

Essential 7Hz

Physiological 10Hz

Psychogenic variable

The use of dopaminergic drugs in individuals with Parkinson’s disease increases their susceptibility to NMS. NMS is more likely to develop when there is a modification in the dosage of dopaminergic and antipsychotic medications. While it is possible, NMS does not typically arise without the administration of dopamine-affecting drugs.

Serotonin Syndrome and Neuroleptic Malignant Syndrome are two conditions that can be difficult to differentiate. Serotonin Syndrome is caused by excess serotonergic activity in the CNS and is characterized by neuromuscular abnormalities, altered mental state, and autonomic dysfunction. On the other hand, Neuroleptic Malignant Syndrome is a rare acute disorder of thermoregulation and neuromotor control that is almost exclusively caused by antipsychotics. The symptoms of both syndromes can overlap, but there are some distinguishing clinical features. Hyper-reflexia, ocular clonus, and tremors are more prominent in Serotonin Syndrome, while Neuroleptic Malignant Syndrome is characterized by uniform ‘lead-pipe’ rigidity and hyporeflexia. Symptoms of Serotonin Syndrome usually resolve within a few days of stopping the medication, while Neuroleptic Malignant Syndrome can take up to 14 days to remit with appropriate treatment. The following table provides a useful guide to the main differentials of Serotonin Syndrome and Neuroleptic Malignant Syndrome.

The Corpus Callosum and Circle of Willis: Important Structures in the Brain

The corpus callosum is a thick bundle of fibers that connects the two cerebral hemispheres. When this structure is divided, communication between the hemispheres is disrupted, resulting in observable effects through experimental techniques. For instance, if an object is presented to the left visual field only (and therefore processed by the right visual cortex only), a subject may be unable to name the object out loud due to the speech center typically being located in the left hemisphere.

On the other hand, the Circle of Willis is a crucial part of the cerebral circulation. If the optic chiasm is divided, it can lead to specific visual problems known as chiasmal syndrome. These structures play important roles in brain function and can have significant consequences when damaged of disrupted.

Erik Erikson is known as the father of psychosocial development and the architect of identity due to his significant contribution of placing psychoanalytic concepts in a social and cultural context. He outlined eight stages of psychosocial development, including Trust vs. Mistrust, Autonomy vs. Shame and Doubt, Initiative vs. Guilt, Industry vs. Inferiority, Identity vs. Role diffusion, Intimacy vs. Isolation, Generativity vs. Stagnation, and Ego Integrity vs. Despair. These stages differ from Freud’s stages of psychosocial development. On the other hand, Carl Gustav Jung introduced the concept of archetypes, which include Self, Shadow, Anima, and Animus. Archetypes are the original models from which all other similar persons, objects, of concepts are derived, copied, patterned, of emulated.

Initially used to treat tuberculosis, iproniazid was found to have a positive impact on patients’ moods. Kline’s publication provided the first evidence supporting its effectiveness in treating depression.

A Historical Note on the Development of Zimelidine, the First Selective Serotonin Reuptake Inhibitor

In 1960s, evidence began to emerge suggesting a significant role of serotonin in depression. This led to the development of zimelidine, the first selective serotonin reuptake inhibitor (SSRI). Zimelidine was derived from pheniramine and was marketed in Europe in 1982. However, it was removed from the market in 1983 due to severe side effects such as hypersensitivity reactions and Guillain-Barre syndrome.

Despite its short-lived availability, zimelidine paved the way for the development of other SSRIs such as fluoxetine, which was approved by the FDA in 1987 and launched in the US market in 1988 under the trade name Prozac. The development of SSRIs revolutionized the treatment of depression and other mood disorders, providing a safer and more effective alternative to earlier antidepressants such as the tricyclics and MAO inhibitors.

Hyponatremia in Psychiatric Patients

Hyponatremia, of low serum sodium, can occur in psychiatric patients due to the disorder itself, its treatment, of other medical conditions. Symptoms include nausea, confusion, seizures, and muscular cramps. Drug-induced hyponatremia is known as the syndrome of inappropriate antidiuretic hormone hypersecretion (SIADH), which results from excessive secretion of ADH and fluid overload. Diagnosis is based on clinically euvolaemic state with low serum sodium and osmolality, raised urine sodium and osmolality. SSRIs, SNRIs, and tricyclics are the most common drugs that can cause SIADH. Risk factors for SIADH include starting a new drug, and treatment usually involves fluid restriction and sometimes demeclocycline.

The act of repeating phrases that one feels compelled to perform is considered a compulsion. Compulsions are actions, either physical or mental, that one feels driven to perform. Obsessions, on the other hand, are recurrent and intrusive thoughts, urges, of images. The urge to hoard, for example, is an obsession rather than a compulsion. Compulsions are not inherently pleasurable and are performed to reduce anxiety. It is important to note that in order to qualify as a compulsion under DSM-5, the behavior must be time-consuming (taking more than 1 hour per day) of cause significant distress of impairment in important areas of functioning. Therefore, the behavior that is most suggestive of a compulsion is one that meets these criteria.

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by the presence of either obsessions or compulsions, and often both. Obsessions are repetitive and persistent thoughts, images, of impulses that are intrusive and unwanted, while compulsions are repetitive behaviors of rituals that an individual feels driven to perform in response to an obsession of according to rigid rules. The symptoms can cause significant functional impairment and/of distress. To diagnose OCD, the essential features include the presence of persistent obsessions and/of compulsions that are time-consuming of result in significant distress of impairment in important areas of functioning. The symptoms cannot be attributed to another medical condition of the effects of a substance of medication on the central nervous system.

Dissociative seizures, also known as pseudoseizures of functional seizures, are abnormal paroxysmal manifestations that resemble epileptic seizures but are not related to abnormal epileptiform discharges. They can be caused by physical factors such as hypoglycemia of cardiac dysfunction, but more commonly result from mental of emotional processes. Dissociative seizures are more common in females and tend to have an onset in late adolescence. Distinguishing between true seizures and pseudoseizures can be challenging, but a rise in serum prolactin levels after a seizure is a helpful diagnostic tool. Treatment options for psychogenic nonepileptic seizures are limited, with cognitive-behavioral therapy being the most studied and effective intervention.

Serotonin Syndrome and Neuroleptic Malignant Syndrome are two conditions that can be difficult to differentiate. Serotonin Syndrome is caused by excess serotonergic activity in the CNS and is characterized by neuromuscular abnormalities, altered mental state, and autonomic dysfunction. On the other hand, Neuroleptic Malignant Syndrome is a rare acute disorder of thermoregulation and neuromotor control that is almost exclusively caused by antipsychotics. The symptoms of both syndromes can overlap, but there are some distinguishing clinical features. Hyper-reflexia, ocular clonus, and tremors are more prominent in Serotonin Syndrome, while Neuroleptic Malignant Syndrome is characterized by uniform ‘lead-pipe’ rigidity and hyporeflexia. Symptoms of Serotonin Syndrome usually resolve within a few days of stopping the medication, while Neuroleptic Malignant Syndrome can take up to 14 days to remit with appropriate treatment. The following table provides a useful guide to the main differentials of Serotonin Syndrome and Neuroleptic Malignant Syndrome.

ADHD medications can be classified into stimulant and non-stimulant drugs. The therapeutic effects of these drugs are believed to be mediated through the action of noradrenaline in the prefrontal cortex. Common side effects of these drugs include decreased appetite, insomnia, nervousness, headache, and nausea. Stimulant drugs like dexamphetamine, methylphenidate, and lisdexamfetamine inhibit the reuptake of dopamine and noradrenaline. Non-stimulant drugs like atomoxetine, guanfacine, and clonidine work by increasing noradrenaline levels in the synaptic cleft through different mechanisms. The most common side effects of these drugs are decreased appetite, somnolence, headache, and abdominal pain.

The PANSS is commonly utilized in clinical trials to assess positive and negative symptoms as well as general psychopathology (30 items in total). To measure extrapyramidal side effects, the Simpson Angus Scale, Abnormal Involuntary Movement Scale (AIMS), and Barnes Akathisia Scale are frequently employed. While the Clinical Global Impression (CGI) scale provides a general score of 1 to 5 for a patient’s overall presentation, it may not be as useful for evaluating a specific positive symptom of schizophrenia as the question suggests.

Depression has been found to be strongly associated with cardiovascular disease, even after controlling for other risk factors such as smoking. Studies have demonstrated that depression is an independent predictor of both fatal and non-fatal ischaemic heart disease.

Some important noradrenaline reuptake inhibitors (NaRIs) include Reboxetine and Atomoxetine.

Mechanisms of Action of Different Drugs

Understanding the mechanisms of action of different drugs is crucial for medical professionals. It is a common topic in exams and can earn easy marks if studied well. This article provides a list of drugs and their mechanisms of action in different categories such as antidepressants, anti dementia drugs, mood stabilizers, anxiolytic/hypnotic drugs, antipsychotics, drugs of abuse, and other drugs. For example, mirtazapine is a noradrenaline and serotonin specific antidepressant that works as a 5HT2 antagonist, 5HT3 antagonist, H1 antagonist, alpha 1 and alpha 2 antagonist, and moderate muscarinic antagonist. Similarly, donepezil is a reversible acetylcholinesterase inhibitor used as an anti dementia drug, while valproate is a GABA agonist and NMDA antagonist used as a mood stabilizer. The article also explains the mechanisms of action of drugs such as ketamine, phencyclidine, buprenorphine, naloxone, atomoxetine, varenicline, disulfiram, acamprosate, and sildenafil.

Several scales are available to measure medication adherence attitudes and behaviors in psychiatric patients, particularly those with schizophrenia. The Rating of Medication Influences (ROMI) scale has 20 interviewer-rated items with good inter-rater reliability. The ASK-20 Adherence Barrier Survey measures barriers to adherence with 20 clinical items. The Brief Evaluation of Medication Influences and Beliefs (BEMIB) scale is an eight-item Likert-type scale that measures costs and benefits of medication use based on the health belief model. The Drug Attitude Inventory is a 30-item self-report scale that evaluates subjective effects of antipsychotic drugs among patients with schizophrenia. The Medication Adherence Rating Scale (MARS) is a 10-item self-report scale derived from the Drug Attitude Inventory and Medication Adherence Questionnaire, and is used in patients with schizophrenia and psychosis.

The recommended treatment options for obsessive-compulsive disorder and body dysmorphic disorder, according to NICE guidelines, include the use of selective serotonin reuptake inhibitors (SSRIs) of cognitive behavioural therapy (CBT), of a combination of both. Other therapies such as cognitive analytical therapy, interpersonal therapy, and psychodynamic psychotherapy have not been found to have sufficient evidence to support their use in managing OCD. Additionally, referral to an anxiety management group would not provide targeted treatment for OCD.

Engrossment refers to the emotional connection that a father develops with his child. This term was coined by Greenberg and Morris in their 1974 study, which explored the impact of newborns on fathers. In contrast, Bowlby used the term ‘attachment’ to describe the bond that develops between a child and their mother. Bonding, on the other hand, refers to the process by which a mother develops a strong emotional connection with her child. Imprinting is a phenomenon observed in some animal species, where newborns acquire certain behavioral characteristics from their parents shortly after birth. Finally, sociability is a crucial aspect of attachment, as it involves the pursuit of social contact and connection with others.
