Abstract:
Electroconvulsive therapy (ECT) was given to 16 non-depressed, non-demented patients with advanced Parkinson's disease (PD). In all the patients an antiparkinsonian effect was seen, lasting for 18 months in one patient, 3-5 months in seven patients, and a few days to four weeks in eight patients. After ECT the levels of homovanillic acid and neuropeptide Y in cerebrospinal fluid (CSF) were significantly increased. The eight patients with long lasting motor improvement after ECT had significantly lower CSF-3-methoxy-4-hydroxyphenylglycol compared to the group with short lasting improvement. Five patients developed transitory mental confusion after ECT. In these patients, and in no others, a high albumin-ratio was found already before ECT was given - an indication of blood CSF barrier damage. Our results suggest that ECT is valuable in patients with drug refractory PD or PD with intolerance to antiparkinsonian drugs.
