Amnesia of Uncertain Etiology in an Adolescent during COVID-19 Pandemic: A Case Report
Abstract
Sudden retrograde memory loss, in the absence of neurological causes, is usually referred to as a dissociative symptom. Dissociative amnesia, defined in the DSM-V as an inability to remember important autobiographical experiences, usually of a traumatic or stressful nature, is however a controversial phenomenon. Few cases with this pattern are described in the scientific literature and still fewer regarding adolescents. The objective of this study was to describe the case of an unexplained sudden memory loss that only partially fits with the criteria for dissociative amnesia, in a juvenile patient aged 16 years, which occurred during the COVID-19 lockdown. After the exclusion of any organic disturbances, 10 days after the clinical onset, a series of psychometric (neuropsychological and psychodiagnostics) tests were administered to the patient. Recent distress associated with COVID-19 lockdown was reported, while no previous significant distress or psychiatric history emerged during the clinical interview, conducted with the patient and parents. Severe disturbances in remote memory tests were registered, while no impairments in cognitive or anterograde amnestic functions were found or personality disorders. The disturbance was diagnosed as “amnesia of uncertain etiology.”
