Acute reversible leukoencephalopathy with increased urinary alpha-ketoglutarate

Definition

A rare neurometabolic disease characterized by acute, reversible, and sometimes recurrent neurologic deterioration (including drowsiness, hypotonia, dysarthria, and ataxia) during a febrile illness. The condition is associated with reversible leukoencephalopathy and persistently increased urinary excretion (and sometimes cerebrospinal fluid concentration) mainly of alpha-ketoglutarate and N-acetylaspartate.
