Understanding Personality Disorders: Borderline Personality Disorder and Other Types

Personality disorders are complex and severe disturbances in an individual’s character and behavior, causing significant personal and social disruption. These disorders are challenging to treat, but psychological and pharmacological interventions can help manage symptoms. One of the most common types of personality disorder is borderline personality disorder, characterized by intense emotions, unstable relationships, impulsive behavior, self-harm, and abandonment anxieties. Other types of personality disorders include schizoid personality disorder, avoidant personality disorder, dependent personality disorder, and narcissistic personality disorder. Understanding these disorders can help individuals seek appropriate treatment and support.

Lithium levels should be checked 12 hours after the last dose, ideally in the evening before bloods are taken the following morning. Taking the sample too soon or too late can lead to incorrect dosing adjustments.

Lithium is a medication used to stabilize mood in individuals with bipolar disorder and as an adjunct in treatment-resistant depression. It has a narrow therapeutic range of 0.4-1.0 mmol/L and is primarily excreted by the kidneys. The mechanism of action is not fully understood, but it is believed to interfere with inositol triphosphate and cAMP formation. Adverse effects may include nausea, vomiting, diarrhea, fine tremors, nephrotoxicity, thyroid enlargement, ECG changes, weight gain, idiopathic intracranial hypertension, leucocytosis, hyperparathyroidism, and hypercalcemia.

Monitoring of patients taking lithium is crucial to prevent adverse effects and ensure therapeutic levels. It is recommended to check lithium levels 12 hours after the last dose and weekly after starting or changing the dose until levels are stable. Once established, lithium levels should be checked every three months. Thyroid and renal function should be monitored every six months. Patients should be provided with an information booklet, alert card, and record book to ensure proper management of their medication. Inadequate monitoring of patients taking lithium is common, and guidelines have been issued to address this issue.

The presence of lanugo hair, which is fine and downy hair that grows in response to body fat loss, can be a characteristic physical finding that supports the diagnosis of anorexia nervosa. However, this should be considered alongside other features such as the failure of secondary sexual characteristics, bradycardia, cold intolerance, and a yellow tinge on the skin (hypercarotenaemia). Anosmia is not typically associated with anorexia nervosa, but it may be relevant in patients with Kallmann syndrome, which involves anosmia and delayed or absent puberty. Hirsutism, which is excessive hair growth, is indicative of elevated testosterone levels and is not compatible with anorexia nervosa. Hyperkalaemia is an incorrect feature, as hypokalaemia is the most common electrolyte abnormality in anorexia. Patients with anorexia nervosa often have high cholesterol levels in their blood.

Characteristics of Anorexia Nervosa

Anorexia nervosa is a disorder that is characterized by a number of clinical signs and physiological abnormalities. The most notable feature of this disorder is a reduced body mass index, which is often accompanied by bradycardia and hypotension. In addition, individuals with anorexia nervosa may experience enlarged salivary glands, which can cause discomfort and difficulty swallowing.

Physiological abnormalities associated with anorexia nervosa include hypokalaemia, which is a deficiency of potassium in the blood, as well as low levels of FSH, LH, oestrogens, and testosterone. Individuals with anorexia nervosa may also have raised levels of cortisol and growth hormone, impaired glucose tolerance, hypercholesterolaemia, hypercarotinaemia, and low T3.

Overall, anorexia nervosa is a complex disorder that can have a significant impact on an individual’s physical and emotional well-being. It is important for individuals who are struggling with this disorder to seek professional help in order to receive the support and treatment they need to recover.

According to NICE, lithium levels should be checked one week after starting treatment, one week after any dose changes, and weekly until stable levels are achieved. Once stable levels are reached, lithium levels should be checked every 3 months, with the sample taken 12 hours after the dose. It is important to note that a trough level taken immediately before a dose is only applicable for certain medications, such as twice-daily clozapine.

Individuals with schizotypal personality disorder exhibit peculiar behavior, speech, and beliefs and typically do not have any close friends outside of their family.

Personality disorders are a set of personality traits that are maladaptive and interfere with normal functioning in life. It is estimated that around 1 in 20 people have a personality disorder, which are typically categorized into three clusters: Cluster A, which includes Odd or Eccentric disorders such as Paranoid, Schizoid, and Schizotypal; Cluster B, which includes Dramatic, Emotional, or Erratic disorders such as Antisocial, Borderline (Emotionally Unstable), Histrionic, and Narcissistic; and Cluster C, which includes Anxious and Fearful disorders such as Obsessive-Compulsive, Avoidant, and Dependent.

Paranoid individuals exhibit hypersensitivity and an unforgiving attitude when insulted, a reluctance to confide in others, and a preoccupation with conspiratorial beliefs and hidden meanings. Schizoid individuals show indifference to praise and criticism, a preference for solitary activities, and emotional coldness. Schizotypal individuals exhibit odd beliefs and magical thinking, unusual perceptual disturbances, and inappropriate affect. Antisocial individuals fail to conform to social norms, deceive others, and exhibit impulsiveness, irritability, and aggressiveness. Borderline individuals exhibit unstable interpersonal relationships, impulsivity, and affective instability. Histrionic individuals exhibit inappropriate sexual seductiveness, a need to be the center of attention, and self-dramatization. Narcissistic individuals exhibit a grandiose sense of self-importance, lack of empathy, and excessive need for admiration. Obsessive-compulsive individuals are occupied with details, rules, and organization to the point of hampering completion of tasks. Avoidant individuals avoid interpersonal contact due to fears of criticism or rejection, while dependent individuals have difficulty making decisions without excessive reassurance from others.

Personality disorders are difficult to treat, but a number of approaches have been shown to help patients, including psychological therapies such as dialectical behavior therapy and treatment of any coexisting psychiatric conditions.

Conditions for Deprivation of Liberty Safeguards (DoLS) Authorisation

DoLS authorisation is a legal process that allows a person to be deprived of their liberty in a care home or hospital for their own safety. However, certain conditions must be met before authorisation can be granted. Firstly, the patient must reside in a care home or hospital, and an application to the Court of Protection must be made if they reside in their own home. Secondly, the patient must lack capacity for decisions regarding treatment. Thirdly, the patient’s lack of an advance decision about their treatment does not prevent DoLS authorisation. Fourthly, the patient must be above 18 years of age. Finally, the patient must have a mental disorder, such as dementia, but it is important to consider if they meet the criteria for detention under the Mental Health Act 1983.

Korsakoff’s syndrome is a complication that can arise from Wernicke’s encephalopathy, and it is characterized by anterograde amnesia, retrograde amnesia, and confabulation. In this case, the patient displays confusion, ataxia, and ophthalmoplegia, as well as anterograde and retrograde amnesia with confabulation, which suggests that they have progressed to Korsakoff’s syndrome. Wernicke’s encephalopathy is caused by a deficiency in thiamine (vitamin B1), which is often due to chronic alcohol abuse or malnutrition. It presents with confusion, ataxia, and oculomotor dysfunction, which can lead to Korsakoff’s syndrome if left untreated. Brain tumors typically present with symptoms of increased intracranial pressure and focal neurological deficits, which are not present in this case. Lewy body dementia can be diagnosed if a patient with decreased cognition displays two or more of the following symptoms: parkinsonism, visual hallucinations, waxing-and-waning levels of consciousness, and rapid-eye-movement (REM) sleep behavior disorder. Transient global amnesia is a temporary condition that involves retrograde and anterograde amnesia following a stressful event, lasting between 2-8 hours but less than 24 hours. Based on the patient’s symptoms and history of alcohol abuse, Korsakoff’s syndrome is the most likely diagnosis.

Understanding Korsakoff’s Syndrome

Korsakoff’s syndrome is a memory disorder that is commonly observed in individuals who have a history of alcoholism. The condition is caused by a deficiency of thiamine, which leads to damage and bleeding in the mammillary bodies of the hypothalamus and the medial thalamus. Korsakoff’s syndrome often develops after untreated Wernicke’s encephalopathy.

The symptoms of Korsakoff’s syndrome include anterograde amnesia, which is the inability to form new memories, and retrograde amnesia. Individuals with this condition may also experience confabulation, which is the production of fabricated or distorted memories to fill gaps in their recollection.

When considering the use of Paroxetine during pregnancy, it is important to note that it can increase the risk of congenital malformations, especially during the first trimester. The use of SSRIs during pregnancy should be carefully evaluated, weighing the potential benefits against the risks. While there is a small increased risk of congenital heart defects when using SSRIs during the first trimester, using them during the third trimester can result in persistent pulmonary hypertension of the newborn. Therefore, it is crucial to consider all potential risks before deciding to use Paroxetine or any other SSRIs during pregnancy.

Selective serotonin reuptake inhibitors (SSRIs) are commonly used as the first-line treatment for depression. Citalopram and fluoxetine are the preferred SSRIs, while sertraline is recommended for patients who have had a myocardial infarction. However, caution should be exercised when prescribing SSRIs to children and adolescents. Gastrointestinal symptoms are the most common side-effect, and patients taking SSRIs are at an increased risk of gastrointestinal bleeding. Patients should also be aware of the possibility of increased anxiety and agitation after starting a SSRI. Fluoxetine and paroxetine have a higher propensity for drug interactions.

The Medicines and Healthcare products Regulatory Agency (MHRA) has issued a warning regarding the use of citalopram due to its association with dose-dependent QT interval prolongation. As a result, citalopram and escitalopram should not be used in patients with congenital long QT syndrome, known pre-existing QT interval prolongation, or in combination with other medicines that prolong the QT interval. The maximum daily dose of citalopram is now 40 mg for adults, 20 mg for patients older than 65 years, and 20 mg for those with hepatic impairment.

When initiating antidepressant therapy, patients should be reviewed by a doctor after 2 weeks. Patients under the age of 25 years or at an increased risk of suicide should be reviewed after 1 week. If a patient responds well to antidepressant therapy, they should continue treatment for at least 6 months after remission to reduce the risk of relapse. When stopping a SSRI, the dose should be gradually reduced over a 4 week period, except for fluoxetine. Paroxetine has a higher incidence of discontinuation symptoms, including mood changes, restlessness, difficulty sleeping, unsteadiness, sweating, gastrointestinal symptoms, and paraesthesia.

When considering the use of SSRIs during pregnancy, the benefits and risks should be weighed. Use during the first trimester may increase the risk of congenital heart defects, while use during the third trimester can result in persistent pulmonary hypertension of the newborn. Paroxetine has an increased risk of congenital malformations, particularly in the first trimester.

Chronic lithium toxicity is the leading cause of hypothyroidism, which is the most common endocrine disorder. The onset of this condition typically occurs within 6 to 18 months of starting lithium treatment, although the exact mechanism by which lithium inhibits thyroid hormone release is not well understood. While olanzapine does not cause hypothyroidism or hypercalcemia, lithium is not associated with hypoadrenalism. Although undertreatment of bipolar disorder can lead to a depressive episode, the patient in this case has experienced an improvement in mood and the emergence of new somatic symptoms, making hypothyroidism due to lithium toxicity a more probable diagnosis.

Understanding Different Types of Anxiety and Related Disorders

Anxiety and related disorders can manifest in various ways, making it important to understand the different types and their symptoms. Depression with secondary panic attacks is a common occurrence, where panic attacks and other anxiety symptoms are a secondary feature of depression. Agoraphobia is an excessive fear of being in situations where escape or help may not be available, leading to avoidance of such situations. Generalised anxiety disorder is characterised by uncontrollable and irrational worry or anxiety about a wide range of issues and situations. Panic disorder is diagnosed when a person has recurrent, severe panic attacks without an obvious precipitant. Chronic fatigue syndrome is characterised by persistent, unexplained fatigue over several months. Understanding these disorders and their symptoms can help in proper diagnosis and treatment.

Schizophrenia with a gradual onset is indicative of a poor prognosis, whereas the other options suggest a better outcome. Although some studies have linked high intelligence with a higher risk of suicide, generally, individuals with higher intelligence have a more favorable prognosis for schizophrenia.

Schizophrenia is a mental disorder that can have varying prognosis depending on certain factors. Some indicators associated with a poor prognosis include a strong family history of the disorder, a gradual onset of symptoms, a low IQ, a prodromal phase of social withdrawal, and a lack of an obvious precipitant. These factors can contribute to a more severe and chronic course of the illness, making it more difficult to manage and treat. It is important for individuals with schizophrenia and their loved ones to be aware of these indicators and seek appropriate treatment and support.

Investigations for Huntington’s Disease: Genetic Testing, CT Scan, EEG, MRI Scan, and PET Scan

Huntington’s Disease is a genetic disorder that affects the brain, causing progressive motor, cognitive, and psychiatric symptoms. There are several investigations that can be done to confirm the diagnosis and assess disease progression.

Genetic testing is the most useful way to confirm the diagnosis of Huntington’s Disease. A positive result consists of 40 or more CAG repeats on one of the alleles. It is important to provide genetic counselling to patients if they choose to get this test done.

CT scans can be useful later on in the disease, showing loss of striatal volume and an increase in the size of the frontal horns of the lateral ventricles of the brain. However, these findings are not always present early on in the disease, so a CT scan would not be the most useful investigation.

EEGs are not usually done unless another cause for the symptoms, such as epilepsy, is suspected.

MRI scans can also show caudate or striatal atrophy. However, it is important to note that these findings are not always specific to Huntington’s Disease, making this investigation less useful.

PET scans are not routinely done to detect Huntington’s Disease but may be used in combination with other investigations to assess disease progression. Systematic reviews have shown that when they are used, the scan results show differences in brain metabolism, dopaminergic function, and phosphodiesterase levels when assessing the progression of Huntington’s Disease.

The patient is unable to function independently and relies on his parents for daily care, indicating a possible diagnosis of a learning disability. This condition is defined by the Department of Health as a significant reduction in the ability to learn new skills and understand complex information, leading to a decreased ability to cope independently. Symptoms must have started before adulthood and have a lasting impact on development. Other potential diagnoses, such as ADHD, autism spectrum disorder, learning difficulty, and oppositional defiant disorder, do not fit the patient’s symptoms and behaviors.

Understanding Psychotic Symptoms: Delusions, Illusions, Perseveration, and Hallucinations

Psychotic symptoms are not simply exaggerations of normal experiences like anxiety or depression. They include hallucinations, delusions, and thought disorder. Delusions are false beliefs that are not shared by others in a cultural group and can be characteristic of different psychiatric disorders. Persecutory delusions are the most common form in schizophrenia and delusional disorder. Schizophrenia is characterized by episodes of delusions, hallucinations, bizarre behavior, incoherent thought processes, and flat or inappropriate affect. Illusions, on the other hand, are misinterpretations of existing sensory stimuli and suggest delirium or intoxication. Perseveration is the persistent repetition of words, phrases, or simple motor behavior and can occur in delirium, dementia, or psychosis. Hallucinations are perceptions of stimuli that are not there and are less common than delusions in schizophrenia. Mood-congruent delusions are consistent with the reported or observed mood and may be markers of the severity of mood disturbance, while mood-incongruent delusions are less easily explained but are commonly associated with a worse prognosis.

There are various medical conditions that can cause changes in urine and serum osmolality levels. Lithium is a common cause of acquired nephrogenic diabetes insipidus, which is characterized by low urine osmolality and high serum osmolality due to a deficiency in antidiuretic hormone secretion or poor kidney response to ADH. On the other hand, high blood sugar levels are associated with polyuria and polydipsia, which can be indicative of diabetes mellitus. Elevated serum calcium levels may be caused by hyperparathyroidism or vitamin D excess, which can also lead to polyuria and polydipsia. However, if the patient has a history of psychosis, psychogenic polydipsia may be the more likely cause. This condition is characterized by low urine and serum osmolality due to excessive water intake, often seen in middle-aged women with psychiatric comorbidities or after lesions in the hypothalamus affecting thirst centers. Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is another disorder that can cause changes in urine and serum osmolality levels, characterized by high urine osmolality and low serum osmolality due to excessive ADH production.

The Use of Electroconvulsive Therapy (ECT) in Mental Health: Conditions and Recommendations

Electroconvulsive therapy (ECT) is a treatment option for certain mental health conditions. The National Institute for Health and Care Excellence (NICE) recommends ECT for severe depression, catatonia, and prolonged or severe mania, but only if the condition is potentially life-threatening and other treatments have proved ineffective. ECT involves attaching electrodes to the scalp and passing an electrical current through to induce a seizure, which is performed under general anaesthesia. The mechanism of action involved in ECT is still not fully understood, but it is thought to cause a neurotransmitter release that improves symptoms. However, ECT can have side-effects such as memory impairment, headache, confusion, and muscle pains. It is not recommended for moderate depression, post-traumatic stress disorder (PTSD), anxiety, or severe dementia.

The Use of Electroconvulsive Therapy (ECT) in Mental Health: Conditions and Recommendations

Understanding Schizophrenia: Differentiating it from Other Mental Health Disorders

Schizophrenia is a mental health disorder that can be diagnosed if certain criteria are met. These criteria include the presence of two or more symptoms such as delusions, hallucinations, disorganized speech, disorganized/catatonic behavior, or negative symptoms. At least one of the symptoms must be a positive symptom, and they must occur for a period of at least one month (less if treated) and be associated with a decline in functioning for at least six months. Additionally, symptoms cannot occur concurrently with substance use or a mood disorder episode.

In contrast to drug-induced psychosis, this man does not have a history of drug use. Mania, on the other hand, is a mood disorder characterized by predominantly positive feelings such as elation and euphoria. Schizoaffective disorder is diagnosed when there are both prominent psychotic and affective features, but this man does not have prominent affective symptoms. Delusional disorder, which is characterized by the development of a single or related delusions that are usually persistent and sometimes lifelong, does not include hallucinations.

In this case, the man is experiencing auditory hallucinations and delusions about the ghosts of dead children, which are typical symptoms of schizophrenia. Understanding the criteria for schizophrenia and differentiating it from other mental health disorders is crucial for accurate diagnosis and effective treatment.

Understanding Post-Traumatic Stress Disorder (PTSD)

Post-traumatic stress disorder (PTSD) is a mental health condition that can develop in individuals of any age following a traumatic event. This can include experiences such as natural disasters, accidents, or even childhood abuse. PTSD is characterized by a range of symptoms, including re-experiencing the traumatic event through flashbacks or nightmares, avoidance of situations or people associated with the event, hyperarousal, emotional numbing, depression, and even substance abuse.

Effective management of PTSD involves a range of interventions, depending on the severity of the symptoms. Single-session interventions are not recommended, and watchful waiting may be used for mild symptoms lasting less than four weeks. Military personnel have access to treatment provided by the armed forces, while trauma-focused cognitive behavioral therapy (CBT) or eye movement desensitization and reprocessing (EMDR) therapy may be used in more severe cases.

It is important to note that drug treatments for PTSD should not be used as a routine first-line treatment for adults. If drug treatment is used, venlafaxine or a selective serotonin reuptake inhibitor (SSRI), such as sertraline, should be tried. In severe cases, NICE recommends that risperidone may be used. Overall, understanding the symptoms and effective management of PTSD is crucial in supporting individuals who have experienced traumatic events.

Mythbusting: Common Misconceptions About Schizophrenia Treatment

1. Oral antipsychotic treatment and psychological interventions should be offered to those with a first episode of psychosis.
2. Patients with schizophrenia should remain under the care of a psychiatrist lifelong, but can be eligible for shared care with a GP after 12 months of stability.
3. An ECG is only necessary before starting antipsychotic medication in certain circumstances.
4. Before starting any oral antipsychotic medication, various health factors need to be checked in all patients.
5. The choice of antipsychotic medication should be made on an individual basis, taking into account potential side-effects.
6. Early intervention in psychosis services should be accessed urgently for anyone presenting with a first episode of psychosis. Antipsychotic medication should not be initiated in primary care without the advice of a psychiatrist.

Urinary retention may be a side effect of tricyclic antidepressants, particularly with the use of Amitriptyline due to its anticholinergic properties. This can lead to symptoms such as tachycardia, dry mouth, and mydriasis. However, SSRIs like fluoxetine and SNRIs like venlafaxine are less likely to cause urinary retention and dry mouth. Benzodiazepines like diazepam do not have anticholinergic effects.

Tricyclic Antidepressants for Neuropathic Pain

Tricyclic antidepressants (TCAs) were once commonly used for depression, but their side-effects and toxicity in overdose have led to a decrease in their use. However, they are still widely used in the treatment of neuropathic pain, where smaller doses are typically required. TCAs such as low-dose amitriptyline are commonly used for the management of neuropathic pain and the prophylaxis of headache, while lofepramine has a lower incidence of toxicity in overdose. It is important to note that some TCAs, such as amitriptyline and dosulepin, are considered more dangerous in overdose than others.

Common side-effects of TCAs include drowsiness, dry mouth, blurred vision, constipation, urinary retention, and lengthening of the QT interval. When choosing a TCA for neuropathic pain, the level of sedation may also be a consideration. Amitriptyline, clomipramine, dosulepin, and trazodone are more sedative, while imipramine, lofepramine, and nortriptyline are less sedative. It is important to work with a healthcare provider to determine the appropriate TCA and dosage for the individual’s specific needs.
