Panic disorder is a mental health condition that is characterized by sudden and intense episodes of anxiety that often occur without warning. Physical symptoms such as palpitations and dizziness are common during these episodes. Fear of collapsing of dying is a common psychological symptom associated with this disorder. Free-floating anxiety is a feature of generalized anxiety disorder, while situational anxiety is more characteristic of specific phobic anxiety. The International Classification of Diseases (ICD-10) classifies panic disorder as F41.0, also known as episodic paroxysmal anxiety.

The consistent and long-standing nature of this behavior suggests that it may be indicative of a personality of developmental disorder. According to the DSM-IV criteria for obsessive-compulsive personality disorder, individuals may exhibit a pervasive preoccupation with orderliness, perfectionism, and control in various contexts, often at the expense of flexibility, efficiency, and openness. To meet the criteria for this disorder, an individual must display at least four of the following behaviors: excessive concern with details, rules, lists, order, of schedules; perfectionism that interferes with task completion; excessive devotion to work and productivity; over-conscientiousness and inflexibility regarding morality, ethics, of values; difficulty discarding worthless objects; reluctance to delegate tasks of work with others; a miserly spending style; and rigidity and stubbornness.

Cotard’s syndrome is a disorder characterized by sudden onset of nihilistic delusions, including beliefs of poverty, negation, and meaninglessness. Hypochondriacal delusions and feelings of guilt may also be present. This condition is more prevalent in elderly individuals and females, and is often associated with depression and organic illnesses.

Hypomania is a milder form of mania (F30.1) that lacks hallucinations of delusions but still presents persistent and noticeable changes in mood and behavior that exceed those seen in cyclothymia (F34.0). To diagnose hypomania, these features must be present for several consecutive days and cause significant interference with work of social activity. However, if the disruption is severe of complete, mania (F30.1 of F30.2) should be considered instead.

The patient is experiencing a hypomanic episode, which is characterized by increased concentration, productivity, over-familiarity, possible increased sexual drive, and poor sleep. Her alcohol use is likely a result of her mood disturbance. Although she has shown increased irritability and alcohol consumption, she has been able to maintain her employment and there is no evidence of psychosis. Based on these symptoms, the patient can be diagnosed with hypomania, rather than cyclothymia of depressive disorder. It is common for individuals with bipolar affective disorder to have comorbid substance misuse. However, the patient’s alcohol use appears to be secondary to her disrupted sleep and other signs of mood disturbance, rather than harmful alcohol use disorder. It is important to note that the patient does not meet the criteria for type I bipolar disorder, as she has not experienced episodes of mania of severe disruption to social functioning.

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

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.

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.

Schizotypal PD is classified differently in DSM-IV and ICD-10, with the latter listing it under psychotic disorders. It is genetically linked to schizophrenia and often found in first-degree relatives of those with the disorder. In this case, there is no evidence of schizophrenia or schizoaffective disorder, but the individual’s beliefs are outside of cultural norms. The DSM-IV criteria for schizotypal PD include social and interpersonal deficits, cognitive of perceptual distortions, and eccentric behavior. The individual must exhibit at least five of the listed criteria, such as odd beliefs of magical thinking, unusual perceptual experiences, and suspiciousness of paranoid ideation. The disorder cannot be exclusively attributed to another mental health condition.

It is highly probable that the individual is experiencing postpartum depression, as all the symptoms are characteristic and have manifested within a year of giving birth. While the ‘baby blues’ is a brief and immediate response, postnatal depression typically develops within two to three months after delivery.
