RT Journal Article SR Electronic T1 Transient epileptic amnesia differentiated from psychogenic "fugue": neuropsychological, EEG, and PET findings. JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 1002 OP 1004 DO 10.1136/jnnp.57.8.1002 VO 57 IS 8 A1 Kopelman, M D A1 Panayiotopoulos, C P A1 Lewis, P YR 1994 UL http://jnnp.bmj.com/content/57/8/1002.abstract AB A patient had repeated episodes of transient loss of memory, which had been attributed to psychogenic causes. Preservation of his sense of personal identity and the presence of repetitive questioning indicated an organic basis, however, and the multiplicity of the attacks and their brief duration suggested an epileptic aetiology. Although three standard EEGs, CT and MRI were all normal, two sleep EEGs confirmed bilateral foci in the temporal lobes. The attacks responded to an anticonvulsant. A fluoro-deoxyglucose PET scan, performed a few months after the most recent attack, was normal. The patient also had impaired anterograde memory that persisted six months after recovery from the acute attacks.
