In Wernicke-Korsakoff syndrome , for example, damage to the memory centers of the brain from the use of alcohol or malnutrition. Infections that damage brain tissue, including encephalitis and herpes, can also cause amnesia. It emphasizes that there is a continuum, perhaps even a principal similarity, between organic and psychogenic amnesia , which derives from a common brain mechanism underlying both phenomena. However, some have speculated that Christie fabricated the entire episode as revenge. Focal retrograde amnesia : loss of memories for a large portion of their past life, can sometimes follow a fugue, but sometimes not.

In a new paper in Brain , a team of British neuropsychologists has reported their findings from a study of patients diagnosed with psychogenic amnesia – one of the largest ever studies of its kind. In the absence of detectable brain lesions, a differentiation of FRA from psychogenic causes is difficult.

This can be situation specific, loss of memory for a particular incident, or global, complete loss of autobiographical memory including ones identity. Which of the following statements is true of psychogenic amnesia ? It involves memory loss that is limited to personal information. It often involves anterograde amnesia.

Organic amnesia is typically restricted to deficits of memory function leaving other cognitive function intact. Similar restricted memory deficits have also been observed in retrograde psychogenic or dissociative amnesia.

Retrograde psychogenic amnesia is common but anterograde psychogenic amnesia is rare. Some researchers have suggested widespread cognitive impairments in retrograde or mixed anterograde and retrograde psychogenic amnesia. In this disorder, a person may lose personal memories and autobiographical information, but usually only briefly. Here we present a case of pure. The pattern of autobiographical memory loss differed between the psychogenic groups: fugue cases showed a severe and uniform loss of memories for both facts and events across all time periods, whereas the two focal retrograde amnesia groups showed a ‘reversed’ temporal gradient with relative sparing of recent memories.

When people suffer from sudden memory loss, the memories that they lose are generally what are known as episodic or explicit – they forget events and facts.

Temporally graded retrograde amnesia : A short-term impairment in retrieving memory.

Pure retrograde amnesia : Having no trace of anterograde amnesia. Those with fugue-to-focal retrograde amnesia (FRA), in which a more prolonged amnesia follows a fugue state. It inclines to disturb episodic, declarative memory and nonfictional negatively while typically keeping procedural memory integral with no striving for learning new acquaintance.
