This report contains follow-up data on the effects of an anticoagulant-psychotherapy regimen in presenile and senile dementia. Over a two-year period, 49 such patients who were seriously ill were treated with a Coumadin-psychotherapy regimen; 34 (69 percent) improved (4 of them dramatically) and 15 (31 percent) did not improve or became worse. The underlying pathologic processes are discussed, with the rationale for therapy.

A 45-year old women with Huntington's disease (HD) was followed for three years while under an anticoagulant-psychotherapy regimen. The chorea disappeared and the patient improved rather than deteriorating as predicted. All psychotropic drugs were discontinued. This case of reversal of the disease may help to confirm the hypothesis that HD is probably due to circulatory insufficiency in the substantia nigra.
