Numerous developments have improved the safety and efficacy of electro
convulsive therapy (ECT) in recent years, so that ECT is now one of th
e safest forms of treatment under anesthesia. The indications for psyc
hiatric patients are clearly defined. ECT is also under discussion wit
h respect to certain neurological disorders. This discussion has, howe
ver, been largely ignored by the German medical profession. Critical e
valuation of previous experience, especially in the United States and
in Scandinavia, reveals some clinical situations (e.g., akinetic crisi
s in Parkinson's disease) in which a primary neurological indication f
or ECT might be present. ECT is frequently indicated in other brain di
seases if pronounced psychopathological disturbances (especially of a
depressive type) occur and fail to respond to conventional treatment w
ith psychotropic drugs. ECT may then be indicated on a case-by-case ba
sis. ECT should not be withheld from such patients; on the other hand,
there is the risk of uncontrolled expansion of these indica tions for
ECT.
