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.

Types of Delusions

Delusions come in many different forms. It is important to familiarize oneself with these types as they may be tested in an exam. Some of the most common types of delusions include:

– Folie a deux: a shared delusion between two or more people
– Grandiose: belief that one has special powers, beliefs, of purpose
– Hypochondriacal: belief that something is physically wrong with the patient
– Ekbom’s syndrome: belief that one has been infested with insects
– Othello syndrome: belief that a sexual partner is cheating on them
– Capgras delusion: belief that a person close to them has been replaced by a double
– Fregoli delusion: patient identifies a familiar person (usually suspected to be a persecutor) in other people they meet
– Syndrome of subjective doubles: belief that doubles of him/her exist
– Lycanthropy: belief that one has been transformed into an animal
– De Clérambault’s syndrome: false belief that a person is in love with them
– Cotard’s syndrome/nihilistic delusions: belief that they are dead of do not exist
– Referential: belief that others/TV/radio are speaking directly to of about the patient
– Delusional perception: belief that a normal percept (product of perception) has a special meaning
– Pseudocyesis: a condition whereby a woman believes herself to be pregnant when she is not. Objective signs accompany the belief such as abdominal enlargement, menstrual disturbance, apparent foetal movements, nausea, breast changes, and labour pains.

Remembering these types of delusions can be helpful in understanding and diagnosing patients with delusional disorders.

Assessment Tools:

Luria’s Test:
Luria’s test is a motor task designed by Alexander Luria, a Russian neuropsychologist. The test was developed based on his observation that individuals with significant frontal lobe damage were unable to modify their responses to a programmed motor task when the order of actions in the task was changed.

Geriatric Depression Scale:
The Geriatric Depression Scale is a screening tool used to identify depression in older adults. It is not designed to assess cognitive impairment.

Mini-Mental State Examination:
The Mini-Mental State Examination is a brief, 30-question screening tool used to assess cognitive impairment. It does not evaluate frontal lobe functions.

National Adult Reading Test:
The National Adult Reading Test is used to assess the premorbid level of intelligence in English-speaking patients.

Wechsler Adult Intelligence Scale:
The Wechsler Adult Intelligence Scale is a comprehensive assessment tool used to measure intelligence in adults and older adolescents.

The olfactory system contains peripheral and central divisions which are connected by transduction structures. Peripheral division consists mainly of the nostrils, ethmoid bone, nasal cavity, and the olfactory epithelium. Olfactory neurons are receptor cells in the epithelium that detect odour molecules dissolved in the mucus and transmit information about the odour to the brain in a process called sensory transduction. Olfactory nerves and fibers transmit information about odours from the peripheral olfactory system to the central olfactory system of the brain. The main olfactory bulb transmits pulses to both mitral and tufted cells, which help determine odour concentration. These cells also note differences between highly similar odours and use that data to aid in later recognition. The cells are different with the mitral having low firing-rates and being easily inhibited by neighbouring cells, while tufted have high rates of firing and are more difficult to inhibit. The uncus houses the olfactory cortex which includes the piriform cortex, amygdala, olfactory tubercle, and para-hippocampal gyrus. Entorhinal cortex is an area of middle temporal lobe that has connection with the para-hippocampal gyrus.

While it’s not necessary to memorize the precise sequence of all the stressful life events, it’s advisable to have knowledge of the order of the most significant three.

Holmes Rahe Stress Scale (Social Readjustment Rating Scale)

In 1967, Holmes and Rahe conducted a study on the impact of stress on illness. They surveyed over 5,000 medical patients and asked them to report whether they had experienced any of 43 life events in the past two years. Each event was assigned a Life Change Unit (LCU) value, which represented its weight for stress. The higher the score, the more likely the patient was to become ill.

The first 10 life events and their corresponding LCU values are listed below.

1. Death of spouse – 100
2. Divorce – 73
3. Marital separation – 65
4. Jail term – 63
5. Death of a close family member – 63
6. Personal illness – 53
7. Marriage – 50
8. Being fired from work – 47
9. Marital reconciliation – 45
10. Retirement – 45

This scale is known as the Holmes Rahe Stress Scale of the Social Readjustment Rating Scale. It is still widely used today to assess the impact of life events on stress levels and overall health.

The central sulcus divides the frontal lobe from the parietal lobe. It contains the motor cells for the movement function of the body.

Elevated plasma levels of clozapine have been observed in individuals of Asian ethnicity. Conversely, younger patients, males, and smokers tend to have lower plasma levels. The use of carbamazepine can accelerate the metabolism of clozapine, resulting in decreased serum assay levels. However, it is not recommended to use carbamazepine and clozapine together due to the increased risk of bone marrow suppression.

Strategic systemic therapy incorporates reframing and the domino effect. Haley’s approach assumes that symptoms are perpetuated by attempts to suppress them, and reframing involves giving negative emotions of behaviors a positive connotation. The domino effect refers to the improvement of additional problems after resolving an initial issue. Bowen’s family systems approach emphasizes the patient’s ability to maintain their individuality amidst familial tension. The Milan systemic approach uses circular questioning among family members, while Bateson’s paradoxical therapy involves intentionally engaging in undesirable behaviors. Minuchin’s structural model prioritizes the family hierarchy, rules, and boundaries.

Goffman coined the term ‘total institution’ in relation to asylums, which were responsible for fulfilling all the patients’ requirements, thereby hindering their rehabilitation.

D.W. Winnicott – Good enough mother, transitional object: Winnicott believed that a good enough mother is one who provides a secure and nurturing environment for her child, allowing them to develop a sense of self and independence. He also introduced the concept of the transitional object, such as a teddy bear of blanket, which helps a child transition from the mother’s care to the outside world.

Carl Jung – Collective unconscious, archetype, anima, animus: Jung believed in the existence of a collective unconscious, a shared pool of knowledge and experience that all humans possess. He also introduced the concept of archetypes, universal symbols and patterns that are present in the collective unconscious. The anima and animus are archetypes representing the feminine and masculine aspects of the psyche.

Melanie Klein – Paranoid-schizoid position, depressive position, splitting: Klein introduced the concept of the paranoid-schizoid position, a stage of development in which a child experiences intense anxiety and fear of persecution. She also introduced the depressive position, a stage in which the child learns to integrate positive and negative feelings towards others. Splitting is the defense mechanism in which a person sees things as either all good of all bad.

Sigmund Freud – Free association, transference, ego, super-ego, id, eros, thanatos, defense mechanisms, oedipus Complex, the unconscious: Freud is known for his theories on the unconscious mind, including the id, ego, and super-ego. He also introduced the concepts of eros (the life instinct) and thanatos (the death instinct), as well as defense mechanisms such as repression and denial. The Oedipus complex is a theory about a child’s sexual desire for their opposite-sex parent.

Wilfred Bion – Basic assumption group: Bion introduced the concept of the basic assumption group, a group that forms around a shared fantasy of assumption. He believed that these groups can be helpful of harmful, depending on the assumptions they are based on.

Karen Horney – Womb envy: Horney believed that men experience womb envy, a feeling of inferiority and jealousy towards women due to their inability to bear children. She also introduced the concept of neurotic needs, such as the need for affection and the need for power.

Erving Goffman – Total institution: Goffman introduced the concept of the total institution, a place where people are completely cut off from the outside world and subjected to strict rules and regulations. Examples include prisons and mental hospitals.

Siegfried Foulkes – Foundation matrix: Foulkes introduced the concept of the foundation matrix, a group’s shared history and experiences that shape their current dynamics and interactions.

Catecholamines are a group of chemical compounds that have a distinct structure consisting of a benzene ring with two hydroxyl groups, an intermediate ethyl chain, and a terminal amine group. These compounds play an important role in the body and are involved in various physiological processes. The three main catecholamines found in the body are dopamine, adrenaline, and noradrenaline. All of these compounds are derived from the amino acid tyrosine. Overall, catecholamines are essential for maintaining proper bodily functions and are involved in a wide range of physiological processes.

A positive Romberg test suggests the presence of sensory ataxia.

Romberg’s Test for Investigating Ataxia

Romberg’s test is a diagnostic tool used to determine the cause of ataxia. A positive result indicates that the cause is sensory in nature. The test involves asking the patient to stand upright with their feet together and eyes closed. If the patient begins to sway of fall over, the test is considered positive. In cases where there is a cerebellar problem, the patient will exhibit ataxia even when their eyes are open. Romberg’s test is an important tool in diagnosing ataxia and determining the underlying cause of the condition.

While XYY has been proposed as a potential contributor to aggressive behavior, it is more likely that the observed increase in aggression among individuals with this genetic makeup is a result of other factors such as low IQ and social deprivation, which are more prevalent in the XYY population. Therefore, XYY is not considered to be the sole cause of aggressiveness.

XYY Syndrome

XYY Syndrome, also known as Jacobs’ Syndrome of super-males, is a genetic condition where males have an extra Y chromosome, resulting in a 47, XYY karyotype. In some cases, mosaicism may occur, resulting in a 47,XYY/46,XY karyotype. The error leading to the 47,XYY genotype occurs during spermatogenesis of post-zygotic mitosis. The prevalence of XYY Syndrome is as high as 1:1000 male live births, but many cases go unidentified as they are not necessarily associated with physical of cognitive impairments. The most common features are high stature and a strong build, and fertility and sexual development are usually unaffected. In the past, XYY Syndrome was linked to aggressiveness and deviance, but this is likely due to intermediate factors such as reduced IQ and social deprivation. XYY Syndrome is best thought of as a risk factor rather than a cause. There is an increased risk of developmental disorders such as learning difficulties, ASD, ADHD, and emotional problems.

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.

Individuals who have ever experienced manic or hypomanic episodes should not be diagnosed with a ‘single episode depressive disorder’ (ICD-11 6A70).

Depression is diagnosed using different criteria in the ICD-11 and DSM-5. The ICD-11 recognizes single depressive episodes, recurrent depressive disorder, dysthymic disorder, and mixed depressive and anxiety disorder. The DSM-5 recognizes disruptive mood dysregulation disorder, major depressive disorder, persistent depressive disorder, and premenstrual dysphoric disorder.

For a diagnosis of a single depressive episode, the ICD-11 requires the presence of at least five characteristic symptoms occurring most of the day, nearly every day during a period lasting at least 2 weeks. The DSM-5 requires the presence of at least five symptoms during the same 2-week period, with at least one of the symptoms being either depressed mood of loss of interest of pleasure.

Recurrent depressive disorder is characterized by a history of at least two depressive episodes separated by at least several months without significant mood disturbance, according to the ICD-11. The DSM-5 requires at least two episodes with an interval of at least 2 consecutive months between separate episodes in which criteria are not met for a major depressive episode.

Dysthymic disorder is diagnosed when a person experiences persistent depressed mood lasting 2 years of more, according to the ICD-11. The DSM-5 requires depressed mood for most of the day, for more days than not, for at least 2 years, along with the presence of two or more additional symptoms.

Mixed depressive and anxiety disorder is recognized as a separate code in the ICD-11, while the DSM-5 uses the ‘with anxious distress’ qualifier. The ICD-11 requires the presence of both depressive and anxiety symptoms for most of the time during a period of 2 weeks of more, while the DSM-5 requires the presence of both depressive and anxious symptoms during the same 2-week period.

Overall, the criteria for diagnosing depression vary between the ICD-11 and DSM-5, but both require the presence of characteristic symptoms that cause significant distress of impairment in functioning.

Kohlberg’s Six Stages of Moral Development

Kohlberg’s theory of moral development consists of six stages that can be categorized into three levels. The first level is the preconventional stage, which is characterized by obedience and punishment orientation, where the focus is on the direct consequences of actions and unquestioning deference to power. The second stage is the self-interest orientation, where right behavior is defined purely by what is in the individual’s own interest.

The second level is the conventional stage, which is characterized by interpersonal accord and conformity, where the focus is on how the individual will appear to others. The behavior should accord with a consensus view on what is good. The second stage is the authority and social order obedience driven, where what is lawful is judged to be morally right. Right behavior is dictated by societal rules, and there is a greater respect for social order and the need for laws.

The third level is the postconventional stage, which is characterized by the social contract orientation, where individual rights determine behavior. The individual views laws and rules as flexible tools for improving human purposes. The fourth stage is the universal ethical principles orientation, where the right action is the one that is consistent with abstract reasoning using universal ethical principles.

It is important to note that the age ranges for Kohlberg’s developmental stages are rough guides, and sources vary widely. Kohlberg developed his stage theory following an experiment he conducted on 72 boys aged 10-16. However, the theory is criticized as sexist as it only included boys.

Copropraxia is a neurological condition characterized by the involuntary expression of socially unacceptable gestures. It is similar to coprolalia, which is the involuntary expression of socially unacceptable words. Other related conditions include echolalia, which involves copying others’ words, and echopraxia, which involves copying others’ actions. Coprophagia, on the other hand, refers to the act of eating faeces, while palilialia involves repeating one’s own sounds. These conditions can be distressing for those who experience them and can have a significant impact on their daily lives. Treatment options may include medication, therapy, and support groups.

A fenestrated cavum septum pellucidum is linked to dementia pugilistica.

Dementia Pugilistica: A Neurodegenerative Condition Resulting from Neurotrauma

Dementia pugilistica, also known as chronic traumatic encephalopathy (CTE), is a neurodegenerative condition that results from neurotrauma. It is commonly seen in boxers and NFL players, but can also occur in anyone with neurotrauma. The condition is characterized by symptoms such as gait ataxia, slurred speech, impaired hearing, tremors, disequilibrium, neurobehavioral disturbances, and progressive cognitive decline.

Most cases of dementia pugilistica present with early onset cognitive deficits, and behavioral signs exhibited by patients include aggression, suspiciousness, paranoia, childishness, hypersexuality, depression, and restlessness. The progression of the condition leads to more prominent behavioral symptoms such as difficulty with impulse control, irritability, inappropriateness, and explosive outbursts of aggression.

Neuropathological abnormalities have been identified in CTE, with the most unique feature being the abnormal accumulation of tau in neurons and glia in an irregular, focal, perivascular distribution and at the depths of cortical sulci. Abnormalities of the septum pellucidum, such as cavum and fenestration, are also a common feature.

While the condition has become increasingly rare due to the progressive improvement in sports safety, it is important to recognize the potential long-term consequences of repeated head injuries and take steps to prevent them.

Mental State Exam – Mood and Affect

Affect is a term used to describe a patient’s present emotional responsiveness, which is indicated by their facial expression and tone of voice. It can be described as being within normal range, constricted (where the affect is restricted in range and intensity), blunted (similar to constricted but a bit more so), of flat (where there are virtually no signs of affective expression). Mood, on the other hand, is a more prolonged prevailing state of disposition. A feeling is an active experience of somatic sensation of a passive subjective experience of an emotion, while an emotion is best thought of as a feeling and memory intertwined. Apathy is the absence of feeling. It is important to distinguish between affect and mood, as affect is momentary and mood is more prolonged.

Phenelzine belongs to a class of antidepressants called Monoamine Oxidase Inhibitors (MAOIs). However, it is contraindicated in patients with phaeochromocytoma, a rare tumor that secretes catecholamines, as MAOIs inhibit the breakdown of catecholamines and can lead to hypertensive crises, brain hemorrhage, and even death in such patients.

While antidepressants are generally considered to have a negligible effect on seizure activity in epileptics, caution should be exercised when using MAOIs in patients with thyroid disease. Additionally, as with all antidepressants, MAOIs may precipitate mania and should be used with caution in bipolar disorder, although they are not contraindicated.

Hyponatremia, a condition characterized by low sodium levels, is a potential side effect of most antidepressants, including MAOIs. However, MAOIs are not considered high risk compared to other antidepressant drugs. If sodium levels fall below 125 mmol/L, antidepressants should be stopped.

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 majority of psychotropics undergo significant hepatic metabolism, with the exclusion of amisulpride, sulpiride, gabapentin, and lithium, which experience little to no hepatic metabolism.

The Hering illusion is an optical illusion where straight and parallel lines appear to be curved of bowed outwards when presented in front of a radial background, such as the spokes of a bicycle wheel.

Gestalt Psychology and the Laws of Perceptual Organization

Gestalt psychology emerged as a response to structuralism, which aimed to break down thoughts into their basic components. Instead, Gestalt psychologists recognized that individual items must be examined together, as they interact and add complexity to the overall picture. Max Wertheimer, Kurt Koffka, and Wolfgang Köhler are important names associated with Gestalt psychology. Wertheimer discovered the phi phenomenon, which explains how rapid sequences of perceptual events create the illusion of motion. The Gestalt laws of perceptual organization explain how we tend to organize parts into wholes. These laws include symmetry and order, similarity, proximity, continuity, closure, and common fate. These laws help us understand how the mind groups similar elements into collective entities of totalities, and how spatial or temporal grouping of elements may induce the mind to perceive a collective of totality. Additionally, the laws explain how points that are connected by straight of curving lines are seen in a way that follows the smoothest path, and how things are grouped together if they seem to complete a picture. Finally, elements with the same moving direction are perceived as a collective of unit.

Antidepressants and Their Cardiac Effects

SSRIs are generally recommended for patients with cardiac disease as they may protect against myocardial infarction (MI). Untreated depression worsens prognosis in cardiovascular disease. Post MI, SSRIs and mirtazapine have either a neutral of beneficial effect on mortality. Sertraline is recommended post MI, but other SSRIs and mirtazapine are also likely to be safe. However, citalopram is associated with Torsades de pointes (mainly in overdose). Bupropion, citalopram, escitalopram, moclobemide, lofepramine, and venlafaxine should be used with caution of avoided in those at risk of serious arrhythmia (those with heart failure, left ventricular hypertrophy, previous arrhythmia, of MI).

Tricyclic antidepressants (TCAs) have established arrhythmogenic activity which arises as a result of potent blockade of cardiac sodium channels and variable activity at potassium channels. ECG changes produced include PR, QRS, and QT prolongation and the Brugada syndrome. Lofepramine is less cardiotoxic than other TCAs and seems to lack the overdose arrhythmogenicity of other TCAs. QT changes are not usually seen at normal clinical doses of antidepressants (but can occur, particularly with citalopram/escitalopram). The arrhythmogenic potential of TCAs and other antidepressants is dose-related.

Overall, SSRIs are recommended for patients with cardiac disease, while caution should be exercised when prescribing TCAs and other antidepressants, especially in those at risk of serious arrhythmia. It is important to monitor patients closely for any cardiac effects when prescribing antidepressants.

The caffeine content in brewed coffee is relatively high, with approximately 100 mg per cup. In comparison, tea has a lower caffeine content. Black tea has around 45 mg per cup, while green tea has approximately 25 mg per cup. Instant coffee contains about 60 mg per cup, and a can of Red Bull contains 80 mg of caffeine.

Aripiprazole does not affect the QTc interval and has minimal risk of extrapyramidal side effects, sedation, of weight gain. Amisulpride, citalopram, and quetiapine have a moderate effect on the QTc interval, which requires ECG monitoring due to a prolongation of >10 msec. Haloperidol has a high effect on the QTc interval, which mandates ECG monitoring due to a prolongation of >20 msec.

Macrocytic anaemia is the type that is commonly associated with valproate.

Valproate: Forms, Doses, and Adverse Effects

Valproate comes in three forms: semi-sodium valproate, valproic acid, and sodium valproate. Semi-sodium valproate is a mix of sodium valproate and valproic acid and is licensed for acute mania associated with bipolar disorder. Valproic acid is also licensed for acute mania, but this is not consistent with the Maudsley Guidelines. Sodium valproate is licensed for epilepsy. It is important to note that doses of sodium valproate and semi-sodium valproate are not the same, with a slightly higher dose required for sodium valproate.

Valproate is associated with many adverse effects, including nausea, tremor, liver injury, vomiting/diarrhea, gingival hyperplasia, memory impairment/confusional state, somnolence, weight gain, anaemia/thrombocytopenia, alopecia (with curly regrowth), severe liver damage, and pancreatitis. Increased liver enzymes are common, particularly at the beginning of therapy, and tend to be transient. Vomiting and diarrhea tend to occur at the start of treatment and remit after a few days. Severe liver damage is most likely to occur in the first six months of therapy, with the maximum risk being between two and twelve weeks. The risk also declines with advancing age.

Valproate is a teratogen and should not be initiated in women of childbearing potential. Approximately 10% of children exposed to valproate monotherapy during pregnancy suffer from congenital malformations, with the risk being dose-dependent. The most common malformations are neural tube defects, facial dysmorphism, cleft lip and palate, craniostenosis, cardiac, renal and urogenital defects, and limb defects. There is also a dose-dependent relationship between valproate and developmental delay, with approximately 30-40% of children exposed in utero experiencing delay in their early development, such as talking and walking later, lower intellectual abilities, poor language skills, and memory problems. There is also a thought to be a 3-fold increase of autism in children exposed in utero.

In addition to fluctuating cognition and visual hallucinations, Lewy body dementia often involves sensitivity to neuroleptics. Patients may also experience falls and REM sleep disorder as common symptoms.

Pure word deafness is a condition where a person is unable to comprehend speech despite having normal hearing abilities for other sounds. The individual is capable of speaking, reading, and writing with ease and understanding, but cannot grasp the meaning of spoken words. They perceive words as mere sounds without any recognition of their significance. This condition is also referred to as subcortical auditory dysphasia.

In certain cases, the addition of 5-10 mg of aripiprazole has demonstrated the ability to restore hyperprolactinaemia to normal levels.

Antipsychotics and Sexual Dysfunction: Causes, Risks, and Management

Sexual dysfunction is a common side effect of antipsychotic medication, with the highest risk associated with risperidone and haloperidol due to their effect on prolactin levels. Clozapine, olanzapine, quetiapine, aripiprazole, asenapine, and lurasidone are associated with lower rates of sexual dysfunction. The Arizona Sexual Experiences Scale (ASEX) can be used to measure sexual dysfunction before and during treatment. Management options include excluding other causes, watchful waiting, dose reduction, switching to a lower risk agent, adding aripiprazole, considering an antidote medication, of using sildenafil for erectile dysfunction. It is important to address sexual dysfunction to improve quality of life and medication adherence.
