Extrapyramidal side-effects (EPSE’s) are a group of side effects that affect voluntary motor control, commonly seen in patients taking antipsychotic drugs. EPSE’s include dystonias, parkinsonism, akathisia, and tardive dyskinesia. They can be frightening and uncomfortable, leading to problems with non-compliance and can even be life-threatening in the case of laryngeal dystonia. EPSE’s are thought to be due to antagonism of dopaminergic D2 receptors in the basal ganglia. Symptoms generally occur within the first few days of treatment, with dystonias appearing quickly, within a few hours of administration of the first dose. Newer antipsychotics tend to produce less EPSE’s, with clozapine carrying the lowest risk and haloperidol carrying the highest risk. Akathisia is the most resistant EPSE to treat. EPSE’s can also occur when antipsychotics are discontinued (withdrawal dystonia).

Anorexia is a serious mental health condition that can have severe physical complications. These complications can affect various systems in the body, including the cardiac, skeletal, hematologic, reproductive, metabolic, gastrointestinal, CNS, and dermatological systems. Some of the recognized physical complications of anorexia nervosa include bradycardia, hypotension, osteoporosis, anemia, amenorrhea, hypothyroidism, delayed gastric emptying, cerebral atrophy, and lanugo.

The Royal College of Psychiatrists has issued advice on managing sick patients with anorexia nervosa, recommending hospital admission for those with high-risk items. These items include a BMI of less than 13, a pulse rate of less than 40 bpm, a SUSS test score of less than 2, a sodium level of less than 130 mmol/L, a potassium level of less than 3 mmol/L, a serum glucose level of less than 3 mmol/L, and a QTc interval of more than 450 ms. The SUSS test involves assessing the patient’s ability to sit up and squat without using their hands. A rating of 0 indicates complete inability to rise, while a rating of 3 indicates the ability to rise without difficulty. Proper management and treatment of anorexia nervosa are crucial to prevent of manage these physical complications.

There is insufficient evidence to support a diagnosis of ASD.

Understanding Panic Disorder: Key Facts, Diagnosis, and Treatment Recommendations

Panic disorder is a mental health condition characterized by recurrent unexpected panic attacks, which are sudden surges of intense fear of discomfort that reach a peak within minutes. Females are more commonly affected than males, and the disorder typically onsets during the early 20s. Panic attacks are followed by persistent concern of worry about their recurrence of negative significance, of behaviors intended to avoid their recurrence. The symptoms result in significant impairment in personal, family, social, educational, occupational, of other important areas of functioning.

To diagnose panic disorder, the individual must experience recurrent panic attacks that are not restricted to particular stimuli of situations and are unexpected. The panic attacks are followed by persistent concern of worry about their recurrence of negative significance, of behaviors intended to avoid their recurrence. The symptoms are not a manifestation of another medical condition of substance use, and they result in significant impairment in functioning.

Panic disorder is differentiated from normal fear reactions by the frequent recurrence of panic attacks, persistent worry of concern about the panic attacks of their meaning, and associated significant impairment in functioning. Treatment recommendations vary based on the severity of the disorder, with mild to moderate cases recommended for individual self-help and moderate to severe cases recommended for cognitive-behavioral therapy of antidepressant medication. The classes of antidepressants that have an evidence base for effectiveness are SSRIs, SNRIs, and TCAs. Benzodiazepines are not recommended for the treatment of panic disorder due to their association with a less favorable long-term outcome. Sedating antihistamines of antipsychotics should also not be prescribed for the treatment of panic disorder.

According to NICE, paroxetine has a greater likelihood of causing discontinuation symptoms compared to other SSRIs.

Depression Treatment Guidelines by NICE

The National Institute for Health and Care Excellence (NICE) provides guidelines for the treatment of depression. The following are some general recommendations:

– Selective serotonin reuptake inhibitors (SSRIs) are preferred when prescribing antidepressants.
– Antidepressants are not the first-line treatment for mild depression.
– After remission, continue antidepressant treatment for at least six months.
– Continue treatment for at least two years if at high risk of relapse of have a history of severe or prolonged episodes of inadequate response.
– Use a stepped care approach to depression treatment, starting at the appropriate level based on the severity of depression.

The stepped care approach involves the following steps:

– Step 1: Assessment, support, psychoeducation, active monitoring, and referral for further assessment and interventions.
– Step 2: Low-intensity psychosocial interventions, psychological interventions, medication, and referral for further assessment and interventions.
– Step 3: Medication, high-intensity psychological interventions, combined treatments, collaborative care, and referral for further assessment and interventions.
– Step 4: Medication, high-intensity psychological interventions, electroconvulsive therapy, crisis service, combined treatments, multiprofessional and inpatient care.

Individual guided self-help programs based on cognitive-behavioral therapy (CBT) principles should be supported by a trained practitioner and last 9 to 12 weeks. Physical activity programs should consist of three sessions per week of moderate duration over 10 to 14 weeks.

NICE advises against using antidepressants routinely to treat persistent subthreshold depressive symptoms of mild depression. However, they may be considered for people with a past history of moderate or severe depression, initial presentation of subthreshold depressive symptoms that have been present for a long period, of subthreshold depressive symptoms of mild depression that persist after other interventions.

NICE recommends a combination of antidepressant medication and a high-intensity psychological intervention (CBT of interpersonal therapy) for people with moderate of severe depression. Augmentation of antidepressants with lithium, antipsychotics, of other antidepressants may be appropriate, but benzodiazepines, buspirone, carbamazepine, lamotrigine, of valproate should not be routinely used.

When considering different antidepressants, venlafaxine is associated with a greater risk of death from overdose compared to other equally effective antidepressants. Tricyclic antidepressants (TCAs) except for lofepramine are associated with the greatest risk in overdose. Higher doses of venlafaxine may exacerbate cardiac arrhythmias, and venlafaxine and duloxetine may exacerbate hypertension. TCAs may cause postural hypotension and arrhythmias, and mianserin requires hematological monitoring in elderly people.

The review frequency depends on the age and suicide risk of the patient. If the patient is over 30 and has no suicide risk, see them after two weeks and then at intervals of 2-4 weeks for the first three months. If the patient is under 30 and has a suicide risk, see them after one week.

Understanding Vitamin B12 Deficiency

Vitamin B12 deficiency is a common condition, especially among older adults, and can lead to various psychiatric symptoms. This water-soluble vitamin occurs in three different forms in the human body, and it is absorbed in the terminal ileum after binding with intrinsic factor. Vitamin B12 is a cofactor for two important metabolic reactions, and its deficiency can cause the accumulation of precursors, which can be diagnosed by measuring homocysteine and methylmalonic acid. Common dietary sources of vitamin B12 include meat, fish, and dairy products, and deficiency can be caused by decreased intake, poor absorption, intrinsic factor deficiency, chronic pancreatic disease, parasites, intestinal disease, of metabolic impairment. Symptoms of vitamin B12 deficiency are often nonspecific and can include weakness, fatigue, irritability, developmental delay/regression, paresthesias, anemia, and more. Neurologic changes can occur without hematologic abnormality.

Antipsychotics can be classified in different ways, with the most common being typical (first generation) and atypical (second generation) types. Typical antipsychotics block dopamine (D2) receptors and have varying degrees of M1, Alpha-1, and H1 receptor blockade. Atypical antipsychotics have a lower propensity for extrapyramidal side-effects and are attributed to the combination of relatively lower D2 antagonism with 5HT2A antagonism. They are also classified by structure, with examples including phenothiazines, butyrophenones, thioxanthenes, diphenylbutylpiperidine, dibenzodiazepines, benzoxazoles, thienobenzodiazepine, substituted benzamides, and arylpiperidylindole (quinolone). Studies have found little evidence to support the superiority of atypicals over typicals in terms of efficacy, discontinuation rates, of adherence, with the main difference being the side-effect profile. The Royal College also favors classification by structure.

Anorexia is marked by prolonged hypercortisolism, with increased levels of free cortisol in both the plasma and CSF. Dexamethasone typically fails to suppress cortisol in individuals with anorexia.

Eating Disorders: Lab Findings and Medical Complications

Eating disorders can lead to a range of medical complications, including renal failure, peripheral edema, sinus bradycardia, QT-prolongation, pericardial effusion, and slowed GI motility. Other complications include constipation, cathartic colon, esophageal esophagitis, hair loss, and dental erosion. Blood abnormalities are also common in patients with eating disorders, including hyponatremia, hypokalemia, hypophosphatemia, and hypoglycemia. Additionally, patients may experience leucopenia, anemia, low albumin, elevated liver enzymes, and vitamin deficiencies. These complications can cause significant morbidity and mortality in patients with eating disorders. It is important for healthcare providers to monitor patients for these complications and provide appropriate treatment.

Antipsychotics (Maximum Doses)

It is important to be aware of the maximum doses for commonly used antipsychotics. The following are the maximum doses for various antipsychotics:

– Clozapine (oral): 900 mg/day
– Haloperidol (oral): 20 mg/day
– Olanzapine (oral): 20 mg/day
– Quetiapine (oral): 750mg/day (for schizophrenia) and 800 mg/day (for bipolar disorder)
– Risperidone (oral): 16 mg/day
– Amisulpride (oral): 1200 mg/day
– Aripiprazole (oral): 30 mg/day
– Flupentixol (depot): 400 mg/week
– Zuclopenthixol (depot): 600 mg/week
– Haloperidol (depot): 300 mg every 4 weeks

It is important to keep these maximum doses in mind when prescribing antipsychotics to patients.

Sialadenosis is the term used to describe the enlargement of the salivary glands, particularly the parotids, without any inflammation. This condition is typically recurrent and is commonly linked to an underlying systemic disorder such as alcoholism, diabetes, malnutrition, bulimia, and anorexia nervosa.

It is important for healthcare providers to monitor patients for these complications and provide appropriate treatment.

Asthenic personality disorder, which used to be a common term, is now referred to as dependent personality disorder. It is important to be aware of this older term as it may still appear in older records.

Dependent Personality Disorder is a type of personality disorder where individuals excessively rely on others for support and fear abandonment. This disorder falls under Cluster C personality disorders. The DSM-5 criteria for this disorder includes exhibiting five of more of the following behaviors: difficulty making decisions without input from others, requiring others to take on responsibilities, fear of disagreement, difficulty starting projects without support, excessive need for nurturance and support, feeling vulnerable and helpless when alone, seeking new relationships when one ends, and having an unrealistic fear of being left alone and unable to care for oneself. The ICD-11 removed the specific diagnosis of Dependent Personality Disorder, but individuals can still be diagnosed with a general personality disorder if they exhibit dependent features.

According to a Cochrane review, while Ginkgo biloba may have the potential to decrease TD, there is insufficient evidence to support its regular use as a recommended treatment. Additionally, it should be noted that reducing medication dosage may initially exacerbate TD symptoms.

Tardive Dyskinesia: Symptoms, Causes, Risk Factors, and Management

Tardive dyskinesia (TD) is a condition that affects the face, limbs, and trunk of individuals who have been on neuroleptics for months to years. The movements fluctuate over time, increase with emotional arousal, decrease with relaxation, and disappear with sleep. The cause of TD remains theoretical, but the postsynaptic dopamine (D2) receptor supersensitivity hypothesis is the most persistent. Other hypotheses include the presynaptic dopaminergic/noradrenergic hyperactivity hypothesis, the cholinergic interneuron burnout hypothesis, the excitatory/oxidative stress hypothesis, and the synaptic plasticity hypothesis. Risk factors for TD include advancing age, female sex, ethnicity, longer illness duration, intellectual disability and brain damage, negative symptoms in schizophrenia, mood disorders, diabetes, smoking, alcohol and substance misuse, FGA vs SGA treatment, higher antipsychotic dose, anticholinergic co-treatment, and akathisia.

Management options for TD include stopping any anticholinergic, reducing antipsychotic dose, changing to an antipsychotic with lower propensity for TD, and using tetrabenazine, vitamin E, of amantadine as add-on options. Clozapine is the antipsychotic most likely to be associated with resolution of symptoms. Vesicular monoamine transporter type 2 (VMAT2) inhibitors are agents that cause a depletion of neuroactive peptides such as dopamine in nerve terminals and are used to treat chorea due to neurodegenerative diseases of dyskinesias due to neuroleptic medications (tardive dyskinesia).

Herbal Remedies for Depression and Anxiety

Depression can be treated with Hypericum perforatum (St John’s Wort), which has been found to be more effective than placebo and as effective as standard antidepressants. However, its use is not advised due to uncertainty about appropriate doses, variation in preparations, and potential interactions with other drugs. St John’s Wort can cause serotonin syndrome and decrease levels of drugs such as warfarin and ciclosporin. The effectiveness of the combined oral contraceptive pill may also be reduced.

Anxiety can be reduced with Piper methysticum (kava), but it cannot be recommended for clinical use due to its association with hepatotoxicity.

Schizophrenia: Understanding the Risk Factors

Social class is a significant risk factor for schizophrenia, with people of lower socioeconomic status being more likely to develop the condition. Two hypotheses attempt to explain this relationship, one suggesting that environmental exposures common in lower social class conditions are responsible, while the other suggests that people with schizophrenia tend to drift towards the lower class due to their inability to compete for good jobs.

While early studies suggested that schizophrenia was more common in black populations than in white, the current consensus is that there are no differences in rates of schizophrenia by race. However, there is evidence that rates are higher in migrant populations and ethnic minorities.

Gender and age do not appear to be consistent risk factors for schizophrenia, with conflicting evidence on whether males of females are more likely to develop the condition. Marital status may also play a role, with females with schizophrenia being more likely to marry than males.

Family history is a strong risk factor for schizophrenia, with the risk increasing significantly for close relatives of people with the condition. Season of birth and urban versus rural place of birth have also been shown to impact the risk of developing schizophrenia.

Obstetric complications, particularly prenatal nutritional deprivation, brain injury, and influenza, have been identified as significant risk factors for schizophrenia. Understanding these risk factors can help identify individuals who may be at higher risk for developing the condition and inform preventative measures.

Psychomotor activation, also known as psychomotor agitation, is characterized by increased speed of thinking, difficulty focusing, excessive energy, and a sense of restlessness. These terms can be used interchangeably.

Bipolar Disorder Versus BPD

Bipolar disorder and borderline personality disorder (BPD) can be distinguished from each other based on several factors. Bipolar disorder is characterized by psychomotor activation, which is not typically seen in BPD. Additionally, self-destructive cutting behavior is rare in bipolar disorder but common in BPD. BPD is often associated with sexual trauma, while bipolar disorder has a lower prevalence of sexual trauma. Other BPD features such as identity disturbance and dissociative symptoms are not typically seen in bipolar disorder. Finally, bipolar disorder is highly heritable, while BPD has a lower genetic loading. Understanding these differences is important for accurate diagnosis and treatment.

The formation of the MARSIPAN working group was prompted by the observation that several patients with severe anorexia nervosa were being admitted to general medical units and experiencing deterioration and even death. The working group has put forth a variety of suggestions, and it is advisable to review the college report for comprehensive information (refer to the provided link).

A rating of 0 indicates complete inability to rise, while a rating of 3 indicates the ability to rise without difficulty. Proper management and treatment of anorexia nervosa are crucial to prevent of manage these physical complications.

Teratogens and Their Associated Defects

Valproic acid is a teratogen that has been linked to various birth defects, including neural tube defects, hypospadias, cleft lip/palate, cardiovascular abnormalities, developmental delay, endocrinological disorders, limb defects, and autism (Alsdorf, 2005). Lithium has been associated with cardiac anomalies, specifically Ebstein’s anomaly. Alcohol consumption during pregnancy can lead to cleft lip/palate and fetal alcohol syndrome. Phenytoin has been linked to fingernail hypoplasia, craniofacial defects, limb defects, cerebrovascular defects, and mental retardation. Similarly, carbamazepine has been associated with fingernail hypoplasia and craniofacial defects. Diazepam has been linked to craniofacial defects, specifically cleft lip/palate (Palmieri, 2008). The evidence for steroids causing craniofacial defects is not convincing, according to the British National Formulary (BNF). Selective serotonin reuptake inhibitors (SSRIs) have been associated with congenital heart defects and persistent pulmonary hypertension (BNF). It is important for pregnant women to avoid exposure to these teratogens to reduce the risk of birth defects in their babies.

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 presence of self-destructive cutting behavior is a strong indicator for a diagnosis of borderline personality disorder.

Battle’s sign is a clinical indicator of a basal skull fracture, while Babinski’s sign is indicative of an upper motor neuron lesion. Hoover’s sign is a sign of non-organic paralysis of the leg. Kernig’s sign is a clinical indicator of meningeal irritation.

Skin Changes in Anorexia Nervosa

Anorexia nervosa is an eating disorder characterized by a distorted body image and an intense fear of gaining weight. In addition to the physical effects of malnutrition, anorexia can also cause various skin changes. These changes include xerosis of dry skin, cheilitis of inflammation of the lips, gingivitis of inflammation of the gums, hypertrichiosis of excess hair growth in areas that do not normally have hair, hyperpigmentation, Russell’s sign of scarring on knuckles and back of hand, carotenoderma of yellow/orange skin color, acne, nail changes, acrocyanosis of persistent blue, cyanotic discoloration of the digits, and seborrheic dermatitis. These skin changes can be a sign of underlying malnutrition and should be addressed as part of the treatment plan for anorexia nervosa.

NICE recommends against the use of dosulepin due to the higher risk of cardiac complications and overdose toxicity, which outweigh any potential benefits in terms of tolerability compared to other antidepressants.

Patients and the general population tend to prefer hanging as their method of choice.

2021 National Confidential Inquiry into Suicide and Safety in Mental Health (NCISH) report reveals key findings on suicide rates in the UK from 2008-2018. The rates have remained stable over the years, with a slight increase following the 2008 recession and another rise since 2015/2016. Approximately 27% of all general population suicides were patients who had contact with mental health services within 12 months of suicide. The most common methods of suicide were hanging/strangulation (52%) and self-poisoning (22%), mainly through prescription opioids. In-patient suicides have continued to decrease, with most of them occurring on the ward itself from low lying ligature points. The first three months after discharge remain a high-risk period, with 13% of all patient suicides occurring within this time frame. Nearly half (48%) of patient suicides were from patients who lived alone. In England, suicide rates are higher in males (17.2 per 100,000) than females (5.4 per 100,000), with the highest age-specific suicide rate for males in the 45-49 years age group (27.1 deaths per 100,000 males) and for females in the same age group (9.2 deaths per 100,000). Hanging remains the most common method of suicide in the UK, accounting for 59.4% of all suicides among males and 45.0% of all suicides among females.

Understanding Vitamin B12 Deficiency

Vitamin B12 deficiency is a common condition, especially among older adults, and can lead to various psychiatric symptoms. This water-soluble vitamin occurs in three different forms in the human body, and it is absorbed in the terminal ileum after binding with intrinsic factor. Vitamin B12 is a cofactor for two important metabolic reactions, and its deficiency can cause the accumulation of precursors, which can be diagnosed by measuring homocysteine and methylmalonic acid. Common dietary sources of vitamin B12 include meat, fish, and dairy products, and deficiency can be caused by decreased intake, poor absorption, intrinsic factor deficiency, chronic pancreatic disease, parasites, intestinal disease, of metabolic impairment. Symptoms of vitamin B12 deficiency are often nonspecific and can include weakness, fatigue, irritability, developmental delay/regression, paresthesias, anemia, and more. Neurologic changes can occur without hematologic abnormality.

Compared to the other options, bupropion is classified as high risk for individuals with epilepsy. The remaining options are considered low risk of likely low risk.

Psychotropics and Seizure Threshold in People with Epilepsy

People with epilepsy are at an increased risk for various mental health conditions, including depression, anxiety, psychosis, and suicide. It is important to note that the link between epilepsy and mental illness is bidirectional, as patients with mental health conditions also have an increased risk of developing new-onset epilepsy. Psychotropic drugs are often necessary for people with epilepsy, but they can reduce the seizure threshold and increase the risk of seizures. The following tables provide guidance on the seizure risk associated with different classes of antidepressants, antipsychotics, and ADHD medications. It is important to use caution and carefully consider the risks and benefits of these medications when treating people with epilepsy.

1. Dehydration can lead to medical crisis and urgent medical assessment is necessary.
2. Oral replacement is preferable, but parenteral fluids may be required if the patient is refusing to drink.
3. A white cell count of >4 and neutrophils >1.5 is not normally a cause for concern.
4. Chronic low potassium levels (down to 1.5) in purging are common, but acute changes are more dangerous.
5. An albumin level of 36 is not normally a cause for concern.
6. Glucose levels of 3.0 may be concerning, but immediate action is required if levels drop below 2.5.
7. The Mental Health Act may be used to provide treatment for anorexia nervosa.

Herbal Remedies for Depression and Anxiety

Depression can be treated with Hypericum perforatum (St John’s Wort), which has been found to be more effective than placebo and as effective as standard antidepressants. However, its use is not advised due to uncertainty about appropriate doses, variation in preparations, and potential interactions with other drugs. St John’s Wort can cause serotonin syndrome and decrease levels of drugs such as warfarin and ciclosporin. The effectiveness of the combined oral contraceptive pill may also be reduced.

Anxiety can be reduced with Piper methysticum (kava), but it cannot be recommended for clinical use due to its association with hepatotoxicity.

The patient’s symptoms are consistent with diabetic ketoacidosis, which may be caused by undiagnosed and untreated hyperglycemia and diabetes resulting from clozapine-induced metabolic syndrome. This condition can lead to a medical emergency, as evidenced by a negative base excess on ABG and hyponatremia.

To ensure sufficient efficacy, a proper evaluation of clozapine should span a minimum of 8 weeks while maintaining a plasma trough level of 350-400 µg/L of higher (Schulte, 2003).

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

Epidemiological surveys and prevalence estimates have been conducted to determine the prevalence of various mental health conditions. The Epidemiological Catchment Area (ECA) study was conducted in the mid-1980s using the Diagnostic Interview Schedule (DIS) based on DSM-III criteria. The National Comorbidity Survey (NCS) used the Composite International Diagnostic Interview (CIDI) and was conducted in the 1990s and repeated in 2001. The Adult Psychiatric Morbidity Survey (APMS) used the Clinical Interview Schedule (CIS-R) and was conducted in England every 7 years since 1993. The WHO World Mental Health (WMH) Survey Initiative used the World Mental Health Composite International Diagnostic Interview (WMH-CIDI) and was conducted in close to 30 countries from 2001 onwards.

The main findings of these studies show that major depression has a prevalence of 4-10% worldwide, with 6.7% in the past 12 months and 16.6% lifetime prevalence. Generalised anxiety disorder (GAD) has a 3.1% 12-month prevalence and 5.7% lifetime prevalence. Panic disorder has a 2.7% 12-month prevalence and 4.7% lifetime prevalence. Specific phobia has an 8.7% 12-month prevalence and 12.5% lifetime prevalence. Social anxiety disorder has a 6.8% 12-month prevalence and 12.1% lifetime prevalence. Agoraphobia without panic disorder has a 0.8% 12-month prevalence and 1.4% lifetime prevalence. Obsessive-compulsive disorder (OCD) has a 1.0% 12-month prevalence and 1.6% lifetime prevalence. Post-traumatic stress disorder (PTSD) has a 1.3-3.6% 12-month prevalence and 6.8% lifetime prevalence. Schizophrenia has a 0.33% 12-month prevalence and 0.48% lifetime prevalence. Bipolar I disorder has a 1.5% 12-month prevalence and 2.1% lifetime prevalence. Bulimia nervosa has a 0.63% lifetime prevalence, anorexia nervosa has a 0.16% lifetime prevalence, and binge eating disorder has a 1.53% lifetime prevalence.

These prevalence estimates provide important information for policymakers, healthcare providers, and researchers to better understand the burden of mental health conditions and to develop effective prevention and treatment strategies.

Effectiveness of Antidepressants

In clinical trials, a response to antidepressants is typically defined as a 50% reduction in depression rating scores. For patients with moderate depression, the number needed to treat (NNT) for antidepressants over placebo is 5, while the NNT for antidepressants over true no-treatment is 3. These findings are outlined in the Maudsley Guidelines 14th Edition.
