    Abstract:
    Children with infantile spasms (IS) are generally treated with ACTH although little is known of the biochemical basis of the symptoms and the mechanism of this therapy. We have measured the concentrations of gamma-aminobutyric acid (GABA), homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) in the CSF of IS children, followed the effect of ACTH treatment on these parameters and correlated CSF GABA values with the cause of IS, cranial CT findings and antiepileptic treatment. While significant differences in GABA concentrations were found between the children with IS and those with febrile seizures or nonconvulsive symptoms, these could be accounted for by age, not the disease present. The CSF GABA level was highest in the IS children with normal CT, cryptogenic cause and no antiepileptic treatment, and lowest in those with abnormal CT, symptomatic cause and antiepileptic treatment. The basal level of CSF 5-HIAA in the IS children was higher than that in the nonconvulsive children, but HVA levels did not differ. ACTH therapy did not change the CSF levels of GABA, 5-HIAA and HVA significantly.
