The use of Vigabatrin may lead to permanent visual field constriction in both eyes, causing tunnel vision and potential disability. Additionally, it may harm the central retina and result in reduced visual acuity.

Antiepileptic drugs (AEDs) are commonly used for the treatment of epilepsy, but many of them also have mood stabilizing properties and are used for the prophylaxis and treatment of bipolar disorder. However, some AEDs carry product warnings for serious side effects such as hepatic failure, pancreatitis, thrombocytopenia, and skin reactions. Additionally, some AEDs have been associated with an increased risk of suicidal behavior and ideation.

Behavioral side-effects associated with AEDs include depression, aberrant behaviors, and the development of worsening of irritability, impulsivity, anger, hostility, and aggression. Aggression can occur before, after, of in between seizures. Some AEDs are considered to carry a higher risk of aggression, including levetiracetam, perampanel, and topiramate. However, data on the specific risk of aggression for other AEDs is lacking of mixed. It is important for healthcare providers to carefully consider the potential risks and benefits of AEDs when prescribing them for patients with epilepsy of bipolar disorder.

The main requirement is a mismatch between an individual’s biological sex and their gender identity, which causes significant distress.

Gender identity is the person’s identification of lived role in society, which is separate from their biological sex. Gender can include non-binary and pangender identities, and cisgender refers to people whose gender is congruent with their biological sex. Gender identity is not the same as sexual preference, which is covered by separate diagnostic categories. The ICD-11 has redefined gender identity-related health, replacing diagnostic categories like “transsexualism” and “gender identity disorder of children” with “gender incongruence of adolescence and adulthood” and “gender incongruence of childhood”, respectively. The DSM-5 uses the term ‘gender dysphoria’ to cover the whole range of gender identity disorders, which is characterized by a marked incongruence between one’s experienced/expressed gender and their assigned gender, lasting at least 6 months, and associated with clinically significant distress of impairment in social, occupational, of other important areas of functioning.

Biochemical Changes Associated with Psychotropic Drugs

Psychotropic drugs can have incidental biochemical of haematological effects that need to be identified and monitored. The evidence for many of these changes is limited to case reports of information supplied by manufacturers. The Maudsley Guidelines 14th Edition summarises the important changes to be aware of.

One important parameter to monitor is ALT, a liver enzyme. Agents that can raise ALT levels include clozapine, haloperidol, olanzapine, quetiapine, chlorpromazine, mirtazapine, moclobemide, SSRIs, carbamazepine, lamotrigine, and valproate. On the other hand, vigabatrin can lower ALT levels.

Another liver enzyme to monitor is ALP. Haloperidol, clozapine, olanzapine, duloxetine, sertraline, and carbamazepine can raise ALP levels, while buprenorphine and zolpidem (rarely) can lower them.

AST levels are often associated with ALT levels. Trifluoperazine and vigabatrin can raise AST levels, while agents that raise ALT levels can also raise AST levels.

TSH levels, which are associated with thyroid function, can be affected by aripiprazole, carbamazepine, lithium, quetiapine, rivastigmine, sertraline, and valproate (slightly). Moclobemide can lower TSH levels.

Thyroxine levels can be affected by dexamphetamine, moclobemide, lithium (which can raise of lower levels), aripiprazole (rarely), and quetiapine (rarely).

Overall, it is important to monitor these biochemical changes when prescribing psychotropic drugs to ensure the safety and well-being of patients.

Individuals with borderline personality disorder may have conflicts with their neighbors, but it is unlikely that they would need to relocate multiple times as a result. On the other hand, those with paranoid personality disorder frequently engage in disputes with their neighbors.

Paranoid Personality Disorder is a type of personality disorder where individuals have a deep-seated distrust and suspicion of others, often interpreting their actions as malevolent. This disorder is characterized by a pattern of negative interpretations of others’ words, actions, and intentions, leading to a reluctance to confide in others and holding grudges for long periods of time. The DSM-5 criteria for this disorder include at least four of the following symptoms: unfounded suspicions of exploitation, harm, of deception by others, preoccupation with doubts about the loyalty of trustworthiness of friends of associates, reluctance to confide in others due to fear of malicious use of information, reading negative meanings into benign remarks of events, persistent grudges, perceiving attacks on one’s character of reputation that are not apparent to others and reacting angrily of counterattacking, and recurrent suspicions of infidelity in a partner without justification. The ICD-11 does not have a specific category for paranoid personality disorder but covers many of its features under the negative affectivity qualifier under the element of mistrustfulness.

Childhood Fear: Normal Development

It is normal for children to experience fear and anxiety as they grow and develop. According to Marks’ ‘ontogenetic parade’ theory, children’s fears follow a predictable pattern throughout their development. In the preschool years, children may fear imaginary creatures, animals, strangers, and their environment. As they enter middle childhood, fears of physical danger, bodily injury, and school performance become more prominent. During adolescence, fears about social evaluations and interactions become more common.

Gullone’s research in 1999 identified specific fears that are prominent at different ages. For example, towards the end of the first year, children may fear strangers, heights, and separation anxiety. In preschool years, fears of being alone, the dark, and animals are common. During the school years, children may fear bodily injury, illness, social situations, supernatural phenomena, failure, and criticism. Finally, in adolescence, fears about death, economic and political concerns may persist.

Overall, fear and anxiety are a normal part of child development, and parents and caregivers can support children by acknowledging their fears and helping them develop coping strategies.

The DIS was the survey instrument used in the Epidemiological Catchment Area Study, which was conducted in the United States.

Epidemiological Catchment Area Study: A Landmark Community-Based Survey

The Epidemiological Catchment Area Study (ECA) was a significant survey conducted in five US communities from 1980-1985. The study included 20,000 participants, with 3000 community residents and 500 residents of institutions sampled in each site. The Diagnostic Interview Schedule (DIS) was used to conduct two interviews over a year with each participant.

However, the DIS diagnosis of schizophrenia was not consistent with psychiatrists’ classification, with only 20% of cases identified by the DIS in the Baltimore ECA site matching the psychiatrist’s diagnosis. Despite this, the ECA produced valuable findings, including a lifetime prevalence rate of 32.3% for any disorder, 16.4% for substance misuse disorder, 14.6% for anxiety disorder, 8.3% for affective disorder, 1.5% for schizophrenia and schizophreniform disorder, and 0.1% for somatization disorder.

The ECA also found that phobia had a one-month prevalence of 12.5%, generalized anxiety and depression had a prevalence of 8.5%, obsessive-compulsive disorder had a prevalence of 2.5%, and panic had a prevalence of 1.6%. Overall, the ECA was a landmark community-based survey that provided valuable insights into the prevalence of mental disorders in the US.

The duration of cannabis in the system may vary, but it typically lasts for weeks rather than just a few hours of days. However, if cannabis is used only once, it may only be detectable for a period of 6-24 hours.

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.

Bulimia: Epidemiology and Risk Factors

Bulimia is a prevalent eating disorder, with an estimated prevalence of 0.63% (Qian, 2021). It is more common in women than men, with a ratio of 10:1. The onset of symptoms typically occurs during adolescence.

Several risk factors have been identified for bulimia, including childhood sexual abuse, male homosexuality, having an occupation that focuses on weight, and low self-esteem (Rushing, 2003). Additionally, being female is also a risk factor for developing bulimia.

Overall, understanding the epidemiology and risk factors associated with bulimia is crucial for early identification and intervention to prevent the negative physical and psychological consequences of this disorder.

Budesonide is a type of steroid that is often administered through an inhaler to manage asthma symptoms. However, it has been noted that the use of inhaled steroids can trigger episodes of hypomania and mania. This information was reported in a study by E Brown et al. titled The psychiatric side effects of corticosteroids, which was published in the Annals of Allergy, Asthma & Immunology in 1999.

Drug-Induced Mania: Evidence and Precipitating Drugs

There is strong evidence that mania can be triggered by certain drugs, according to Peet (1995). These drugs include levodopa, corticosteroids, anabolic-androgenic steroids, and certain classes of antidepressants such as tricyclic and monoamine oxidase inhibitors.

Additionally, Peet (2012) suggests that there is weaker evidence that mania can be induced by dopaminergic anti-Parkinsonian drugs, thyroxine, iproniazid and isoniazid, sympathomimetic drugs, chloroquine, baclofen, alprazolam, captopril, amphetamine, and phencyclidine.

It is important for healthcare professionals to be aware of the potential for drug-induced mania and to monitor patients closely for any signs of symptoms. Patients should also be informed of the risks associated with these medications and advised to report any unusual changes in mood of behavior.

A hypomanic episode does not result in significant impairment in social of occupational functioning of require hospitalization, and if it includes psychotic features, it is classified as a manic episode.

Bipolar Disorder Diagnosis

Bipolar and related disorders are mood disorders characterized by manic, mixed, of hypomanic episodes alternating with depressive episodes. The lifetime risk of suicide in individuals with bipolar disorder is estimated to be at least 15 times that of the general population. Under the ICD-11, there are three subtypes of bipolar disorder: Bipolar I, Bipolar II, and Cyclothymic disorder.

Bipolar I disorder is diagnosed when an individual has a history of at least one manic of mixed episode. The typical course of the disorder is characterized by recurrent depressive and manic of mixed episodes. Onset of the first mood episode most often occurs during the late teen years, but onset of bipolar type I can occur at any time through the life cycle. The lifetime prevalence of bipolar I disorder is estimated to be around 2.1%.

Bipolar II disorder is diagnosed when an individual has a history of at least one hypomanic episode and at least one depressive episode. The typical course of the disorder is characterized by recurrent depressive and hypomanic episodes. Onset of bipolar type II most often occurs during the mid-twenties. The number of lifetime episodes tends to be higher for bipolar II disorder than for major depressive disorder of bipolar I disorder.

Cyclothymic disorder is diagnosed when an individual experiences mood instability over an extended period of time characterized by numerous hypomanic and depressive periods. The symptoms are present for more days than not, and there is no history of manic or mixed episodes. The course of cyclothymic disorder is often gradual and persistent, and onset commonly occurs during adolescence of early adulthood.

Rapid cycling is not a subtype of bipolar disorder but instead is a qualifier. It 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. Rapid cycling is associated with an increased risk of suicide and tends to be precipitated by stressors such as life events, alcohol abuse, use of antidepressants, and medical disorders.

Overall, the diagnosis of bipolar disorder requires careful evaluation of an individual’s symptoms and history. Treatment typically involves a combination of medication and psychotherapy.

Diagnostic Overshadowing in Learning Disability

Diagnostic overshadowing is a common phenomenon where a change in behavior of emotion is attributed to learning disability rather than a coexisting mental disorder. This tendency can lead to misdiagnosis and inappropriate treatment, particularly in adults with learning disability admitted to psychiatric wards. It is important for healthcare professionals to consider the possibility of comorbid mental disorders and conduct a thorough assessment to ensure accurate diagnosis and appropriate treatment. By avoiding diagnostic overshadowing, individuals with learning disability can receive the necessary support and care for their mental health needs.

Genomic Imprinting and its Role in Psychiatric Disorders

Genomic imprinting is a phenomenon where a piece of DNA behaves differently depending on whether it is inherited from the mother of the father. This is because DNA sequences are marked of imprinted in the ovaries and testes, which affects their expression. In psychiatry, two classic examples of genomic imprinting disorders are Prader-Willi and Angelman syndrome.

Prader-Willi syndrome is caused by a deletion of chromosome 15q when inherited from the father. This disorder is characterized by hypotonia, short stature, polyphagia, obesity, small gonads, and mild mental retardation. On the other hand, Angelman syndrome, also known as Happy Puppet syndrome, is caused by a deletion of 15q when inherited from the mother. This disorder is characterized by an unusually happy demeanor, developmental delay, seizures, sleep disturbance, and jerky hand movements.

Overall, genomic imprinting plays a crucial role in the development of psychiatric disorders. Understanding the mechanisms behind genomic imprinting can help in the diagnosis and treatment of these disorders.

TCAs, low-potency antipsychotics, topiramate, and SSRIs have been linked to angle-closure glaucoma, a severe condition.

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

Charles Bonnet syndrome (CBS) is a condition where mentally healthy individuals experience vivid and recurring visual hallucinations, also known as fictive visual percepts. These hallucinations are typically small in size, known as lilliputian hallucinations. CBS is commonly found in individuals who have visual impairments due to old age of damage to the eyes of optic pathways. However, not all individuals with such deficits develop CBS. In some cases, CBS may be triggered by a combination of central vision loss due to conditions like macular degeneration and peripheral vision loss from glaucoma. In this context, bilateral lenticular opacities refer to cataracts. For more information on CBS, please refer to the Royal National Institute of Blind People (RNIB).

Consider administering clozapine via the intramuscular route in cases where patients are noncompliant with oral medications, provided that two different antipsychotics (at least one of which is an atypical) have been tried at effective doses and with adequate compliance.

Problem Gambling: Screening and Interventions

Problem gambling, also known as pathological gambling, refers to gambling that causes harm to personal, family, of recreational pursuits. The prevalence of problem gambling in adults ranges from 7.3% to 0.7%, while in psychiatric patients, it ranges from 6% to 12%. Problem gambling typically starts in early adolescence in males and runs a chronic, progressive course with periods of abstinence and relapses.

Screening for problem gambling is done using various tools, including the NODS-CLiP and the South Oaks Gambling Screen (SOGS). Brief interventions have been successful in decreasing gambling, with motivational enhancement therapy (MET) being the most effective. Pharmacological interventions, such as selective serotonin reuptake inhibitors (SSRIs), naltrexone, and mood stabilizers, have also been effective, but the choice of drug depends on the presence of comorbidity. Psychological interventions, particularly cognitive-behavioral treatments, show promise, but long-term follow-up and high drop-out rates are major limitations. Studies comparing psychological and pharmacological interventions are needed.

Schizophrenia in children is rare compared to adults, with a prevalence estimate of 0.05% for those under 15 years old. There are two classifications based on age of onset: early onset schizophrenia (EOS) when symptoms appear between 13-18 years old, and very early onset schizophrenia (VEOS) when symptoms appear at of before 13 years old. EOS and VEOS have atypical features compared to adult-onset schizophrenia, including insidious onset, more severe neurodevelopmental abnormalities, terrifying visual hallucinations, constant inappropriate of blunted effects, higher rates of familial psychopathology, minor response to treatment, and poorer outcomes. Preliminary data suggests that VEOS and EOS may be due to greater familial vulnerability from genetic, psychosocial, and environmental factors. Poor outcomes are most reliably linked to a positive history of premorbid difficulties, greater symptom severity (especially negative symptoms) at baseline, and longer duration of untreated psychosis. Age at psychosis onset and sex are not consistent predictors of outcome.

The categorization of Alzheimer’s severity is based on the MMSE score, where a score of 21-26 is considered mild, 10-20 is moderate, and 0-10 is severe.

Treatment of Dementia: AChE Inhibitors and Memantine

Dementia is a debilitating condition that affects millions of people worldwide. Acetylcholinesterase inhibitors (AChE inhibitors) and memantine are two drugs used in the management of dementia. AChE inhibitors prevent cholinesterase from breaking down acetylcholine, which is deficient in Alzheimer’s due to loss of cholinergic neurons. Donepezil, galantamine, and rivastigmine are AChE inhibitors used in the management of Alzheimer’s. Memantine is an NMDA receptor antagonist that blocks the effects of pathologically elevated levels of glutamate that may lead to neuronal dysfunction.

NICE guidelines recommend the use of AChE inhibitors for managing mild to moderate Alzheimer’s and memantine for managing moderate to severe Alzheimer’s. For those already taking an AChE inhibitor, memantine can be added if the disease is moderate of severe. AChE inhibitors are also recommended for managing mild, moderate, and severe dementia with Lewy bodies, while memantine is considered if AChE inhibitors are not tolerated of contraindicated. AChE inhibitors and memantine are not recommended for vascular dementia, frontotemporal dementia, of cognitive impairment due to multiple sclerosis.

The British Association for Psychopharmacology recommends AChE inhibitors as the first choice for Alzheimer’s and mixed dementia, while memantine is the second choice. AChE inhibitors and memantine are also recommended for dementia with Parkinson’s and dementia with Lewy bodies.

In summary, AChE inhibitors and memantine are important drugs used in the management of dementia. The choice of drug depends on the type and severity of dementia, as well as individual patient factors.

Schizophrenia Prognosis: Factors Predicting Poor Outcome

Several factors have been identified that predict a poor outcome for individuals with schizophrenia. These include being male, having an early age of onset, experiencing a prolonged period of untreated illness, and having severe cognitive and negative symptoms. These symptoms can include difficulties with memory, attention, and decision-making, as well as a lack of motivation, emotional expression, and social functioning. It is important for individuals with schizophrenia to receive early and effective treatment to improve their chances of a better outcome.

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.
