Anankastic personality disorder is a personality disorder characterized by a preoccupation with orderliness, perfectionism, and control. It falls under cluster C personality disorders according to DSM-IV classification.

Deliberate self-harm is commonly associated with cluster B personality disorders. In the United Kingdom, poisoning by drugs accounts for 90% of deliberate self-harm cases, while wrist cutting accounts for 6-7%, and all other methods combined account for 3-4%. Frequent wrist cutting can be a part of recurrent suicidal gestures seen in individuals with depressive disorder, schizophrenia, and borderline personality disorder.

The reasons for wrist cutting are varied and complex, including a means of punishment oneself, reducing tension, feeling bodily instead of emotional pain, wishing to die, testing the benevolence of fate, seeking an interruption to an unendurable state of tension, crying for help, communicating with others, and unbearable symptoms.

Borderline personality disorder (BPD) is characterized by impulsive acts, mood instability, and chaotic relationships. Individuals with BPD are impulsive in areas that have a potential for self-harm and exhibit recurrent suicidal gestures such as wrist cutting, overdose, of self-mutilation.

The symptoms described are consistent with tardive dystonia, which is commonly observed in younger patients who have been exposed to neuroleptic medication. Orofacial dyskinesia is more frequently seen in older patients. The symptoms do not suggest Huntington’s chorea of non-epileptic seizures, as the latter typically do not persist. Friedreich’s ataxia typically presents with muscle weakness and lack of coordination. Tourette’s syndrome is unlikely to cause such severe motor neurological symptoms.

Somatisation is a clinical feature that can be present in a variety of disorders and is not exclusive to schizophrenia. Delusions of guilt and grandeur are more commonly associated with affective psychosis, while running commentary is a classic symptom of schizophrenia and is given diagnostic significance in ICD-10.

An Overview of Anxiety Disorders

Anxiety disorders are a group of mental health conditions that are characterised by excessive and persistent feelings of fear, worry, and apprehension. There are several types of anxiety disorders, each with its own unique set of symptoms and diagnostic criteria.

Social phobia, also known as social anxiety disorder, is characterised by intermittent anxiety that is associated with specific social situations. Individuals with social phobia often feel the need to perform of fear being scrutinised in these situations, leading to avoidance as a maladaptive coping strategy.

Generalised anxiety disorder, on the other hand, is characterised by persistent free-floating anxiety that is not necessarily tied to any specific situation of trigger.

Paranoid personality disorder is not typically associated with anxiety as a key feature, although individuals with this condition may experience other symptoms such as suspiciousness and mistrust.

In contrast, paranoid schizophrenia may involve self-referential delusions, although the cognitive distortions seen in social phobia are not considered delusional.

Finally, specific phobia is a category of anxiety disorders that involves intense fear of anxiety in response to a specific object of situation, such as heights of spiders.

John’s behavior is causing distress and impairment in his ability to participate in family therapy and may have contributed to his child’s depression. His behavior is consistent with histrionic personality disorder, which is only found in the ICD-10. This disorder is characterized by self-dramatization, exaggerated emotions, suggestibility, a shallow and unstable emotional state, a constant need for attention and excitement, inappropriate seductive behavior, and an excessive concern with physical appearance. Other associated features may include egocentricity, self-indulgence, a constant desire for appreciation, easily hurt feelings, and manipulative behavior to meet personal needs.

Diagnosis of Bulimia Nervosa

Bulimia nervosa is the likely diagnosis for the patient, given her recurrent binges and use of laxatives to compensate for them. The DSM-IV criteria for bulimia nervosa require that these features occur more than twice weekly for three months. Weight loss is not a diagnostic requirement. In both anorexia nervosa and bulimia nervosa, self-worth is judged largely of exclusively in terms of shape and weight, and obtaining a reliable dietary history from the patient is unlikely. A key feature of bulimia nervosa is a feeling of loss of control during binge eating episodes.

Differential Diagnosis for a Patient with Temporal Lobe Epilepsy

Temporal lobe epilepsy, also known as complex partial seizures, is characterized by an aura of abdominal symptoms followed by altered consciousness and behavior. This episodic condition can occur rapidly. The presenting symptoms of this patient suggest an acute confusional state, ruling out antibiotic-induced psychosis, which is associated with ongoing antibiotic treatment. Delirium tremens, a severe form of alcohol withdrawal, is also unlikely. Early onset dementia cannot be associated with this presentation due to insufficient information. A differential diagnosis is necessary to determine the underlying cause of the patient’s symptoms.

The typical symptoms of Wernicke’s encephalopathy include ophthalmoplegia (such as horizontal and vertical nystagmus, weakness of paralysis of the lateral rectus muscles, and weakness of paralysis of conjugate gaze), ataxia (primarily affecting stance of gait, often without clear intention tremor), and confusion. If a patient presents with drowsiness, jaundice, and metabolic flap, it may indicate hepatic encephalopathy. On the other hand, nystagmus and intention tremor are indicative of alcohol withdrawal.

De Clérambault’s syndrome is characterized by amorous delusions where the patient believes that a person of higher social status, often a public figure, is in love with them. These delusions are not based on any actual contact of encouragement from the subject. Patients with this syndrome may also experience delusions of persecution. Due to their strong belief in the reality of their delusions, patients often lack insight and may not seek help. Treatment can include psychotherapy and antipsychotics. Other syndromes with delusional symptoms include Capgras syndrome, Cotard’s syndrome, Ekbom’s syndrome, and Othello’s syndrome.

Individuals with social phobia experience anxiety and apprehension regarding the possibility of receiving unfavorable attention from others, leading them to avoid eating in public.
