Abstract

The concentration of free amino acids was measured in the cerebrospinal fluid of four patients with Rett syndrome. The reference material were patients with autistic disorder who had CSF aminoacid levels similar to those reported for healthy children. The concentration of glutamate - but of no other amino acid - was markedly elevated in the CSF of the RS patients.

The results are discussed in the context of excitotoxicity in neurodegenerative disease.
