Synopsis

Forty-nine patients with low serum and cerebrospinal fluid folate levels completed the Ottawa–Wechsler Scale after 7–11 months of folate supplementation (10 mg daily). Twelve patients exhibited major neurological symptoms, while 37 patients displayed depression and minor neurological signs. After folate therapy, Verbal, Performance and Full Wechsler scores were significantly improved (P ≺ 0·0·01). The order of improvement in scores on the Wechsler subtests (from the statistically most significant to the least as measured by the t-statistics) was: Block Design, Digit Symbol, Similarities, Picture Completion, Picture Arrangement, Arithmetic, Object Assembly, Digit Span, Information, and Comprehension.
