In their preliminary report, Kurtzke and Berlin1 did not claim unequivocal effectiveness of isoniazid but suggested that their results warranted further investigation.

It was felt that a study of the effect of the drug on patients with persistent disabling features of the disease would be of special value for the evaluation of its therapeutic efficacy. In addition, a group of patients with other neurological disorders was selected for the
