Clinical interpretations of the measurement of folic acid and vitamin B12 in neuromuscular disease.
56 patients were studied in an attempt to define neurologic complications associated with folic acid and vitamin B12 deficiency. 2 patients had abnormal levels of vitamin B12. 1 of these showed decreased vibRATORY SENSE IN THE LEGS. 10 of 15 patients with serum folate less than 4.0 ng per ml and 16 of 23 patients with serum folate less than 6.0 ng per ml by radioassay had neurologic abnormalities. The control group demonstrated 17/31 with neurologic abnormalities, a figure not significantly different from the deficient group. It is suggested that more patients with "pure folate deficiency" must be analyzed to eliminate the possible role of toxic effects of alcohol and other diseases of the nervous system in patients with low serum folate and neurologic problems.
