Transient global amnesia (TGA) is a syndrome characterized by anterograde amnesia of sudden onset lasting less than 24 h, without other accompanying neurological symptoms. Other organic amnesic syndromes, such as Korsakoff’s syndrome (whether caused by alcohol of not), may exhibit confabulation, but in transient global amnesia, there is only a temporary loss of recent memory and impaired new learning, without any other cognitive abnormalities. Patients remain alert and responsive, and their personal identity is not affected. The prevailing theory is that this amnesia is caused by a temporary dysfunction in the limbic-hippocampus circuits that are essential for memory formation.

Although retrograde amnesia is not predominant, some patients may transiently forget relatively recent memories, as described by Ribot’s law. Most autobiographical memories however, particularly semantic ones are preserved.

Different types of thought disorders are associated with specific personality traits of mental illnesses. Circumstantiality involves taking a long and detailed route to get to the initial point. Loosening of association makes it difficult to follow how one idea connects to the previous one, resulting in derailment. Overinclusive thinking blurs the boundaries between words and concepts, causing unrelated ideas to be associated with each other. Tangentiality involves answers that are related to the question but do not directly answer it.

The patient has a false belief that others are manipulating situations of occurrences to communicate with them, which is known as a delusion of reference.

Bulimia nervosa is a condition characterized by recurrent episodes of binge eating followed by compensatory behaviors such as vomiting, laxative use, of excessive exercise. One of the hallmark physical symptoms of bulimia nervosa is bilateral swelling of the parotid glands, which are located on either side of the face near the ears. This swelling is caused by repeated vomiting and can be a visible sign of the disorder. Other symptoms of bulimia nervosa may include dental problems, gastrointestinal issues, and electrolyte imbalances. The International Classification of Diseases, 10th Revision (ICD-10) classifies bulimia nervosa as F50.2.

Anankastic personality disorder, previously known as obsessive-compulsive personality disorder in DSM-IV, is a condition where individuals are excessively focused on schedules, rules, and details. Their perfectionism can hinder their ability to meet the criteria outlined in ICD-10, which characterizes the disorder as one marked by doubt, excessive conscientiousness, preoccupation with details, checking, stubbornness, caution, and rigidity. People with this disorder may experience persistent and unwanted thoughts of impulses that do not reach the level of an obsessive-compulsive disorder. They may also struggle to function effectively at work due to difficulty completing tasks.

Passivity Phenomena in a Patient: An Example

The patient in question experiences the sensation of an external force attempting to interfere with his thoughts and actions. This is an example of passivity phenomena. Although he holds a belief in black magic, this may be considered a secondary delusional belief. The patient may also exhibit formal thought disorder, but the combination of thought passivity and the belief in external influence is more consistent with an overall description of passivity phenomena.

While overvalued ideas can interfere with normal social functioning, they may be considered culturally appropriate to a lesser degree. However, the nature of the patient’s experiences precludes this possibility. There is no evidence of pseudo of other hallucinatory experiences.

To encourage patients to express themselves freely, doctors use various techniques such as validation, confrontation, clarification, facilitation, and open-ended questions. Validation involves making patients feel more comfortable by normalizing their thoughts, feelings, of behaviors. Confrontation involves pointing out something that the patient may be missing of denying. Clarification is used to clarify something that the patient has said. Facilitation involves using verbal and non-verbal cues to encourage patients to continue sharing. Open-ended questions are used to prompt patients to respond in their own words, rather than with a simple yes or no answer.

Hallucinations of taste, known as gustatory hallucinations, are characterized by unusual of unpleasant taste perceptions. The mechanism behind this disturbance in taste perception is often challenging to explain. Gustatory hallucinations can manifest in various organic conditions, including epilepsy, dementia, schizophrenia, and depression. Additionally, certain psychotropic medications, such as lithium carbonate, can also cause gustatory hallucinations.

The mental state examination involves evaluating and documenting characteristics of mental illness in order to diagnose a clinical syndrome. It includes observing and describing the significant aspects of a person’s mental state at a specific moment in time. This assessment can be conducted before obtaining a patient’s medical history.

Symptom exaggeration is a method of suggesting a behavior that is more problematic than expected to help the patient feel less guilty and provide a more truthful response.

Confrontation involves the doctor pointing out something that the patient may be denying or missing.

Clarification is used to clarify something the patient has said.

Open-ended questions encourage the patient to respond in their own words and cannot be answered with a simple yes of no.

Validation is used to make the patient’s thoughts, feelings, of behaviors seem more acceptable by normalizing them.
