Psychoneurological dilemma of diagnosis of transient amnesia. The case of 36-year-old Tatyana

The article describes the case of 36-year-old Tatyana, whose clinical case was characterized by an episode of transient amnesia lasting less than a day, without other signs of mental and neurological disorders. The patient was admitted to a psychiatric hospital where she was disorientated in place, time and partly in her own personality. There was an acute onset and an abrupt end to the amnestic syndrome, which was not due to mental trauma. Particular attention is paid to the distinction between amnesic syndrome and depersonalization in the context of the phenomenon of “autobiographical amnesia”. According to the diagnostic criteria, the case in question did not meet the parameters of either transient global amnesia or dissociative amnesia. The article provides an overview of modern literature and an analysis of clinical case. It is pointed out that routine psychopathological examination excludes transient global amnesia from differential diagnosis, which may affect the accuracy of the diagnosis.
