title: Biochemical approaches to the nosology of nervous system defects, III.
abstract: In an ever larger number of neurologic conditions, the diagnosis depends on biochemical procedures. These range in complexity from simple screening tests on urine or blood, to analyses of nervous tissue lipids or metabolic studies or explants of brain tissue. Examples of each these are provided.
