West syn·drome

(west),
an encephalopathy in infancy characterized by infantile spasms, arrest of psychomotor development, and hypsarrhythmia.
An early onset condition characterised by a triad:
(1) Infantile spasms,
(2) Interictal EEG pattern termed hypsarrhythmia, and
(3) Mental retardation. Per the international classification, the diagnosis can be made in the presence of two of the three symptoms. The frequent onset of West syndrome in infancy suggests that CNS immaturity may play a key role in its pathogenesis. The clinical response to ACTH and glucocorticoids may be linked to suppression of corticotropin-releasing hormone production
