Transient epileptic amnesia in a memory clinic setting. A report of three cases

• Transient epileptic amnesia (TEA) is a recently described, typically misdiagnosed at presentation, distinctive syndrome, characterized by recurrent, brief attacks of memory loss in middle-aged or elderly people, accompanied by significant interictal memory difficulties. We describe the clinical, neuroimaging, electrophysiological, and neuropsychological characteristics of three patients fulfilling the proposed criteria for TEA, initially referred to our memory clinic for evaluation and treatment of probable dementia. Neuropsychological performance on admission and 6 months after treatment demonstrated a broad range of performance on measures of executive function, lower than expected visuospatial perception, and poor autobiographical memory. TEA should be included in the differential diagnosis of dementia to avoid misdiagnosis and needless medication. It is a benign and treatable condition, yet the associated decline in autobiographical and remote memory despite antiepileptic therapy poses challenges for further research.
