Absence of cognitive impairment after more than 100 lifetime ECT treatments

Am J Psychiatry. 1991 Jul;148(7):929-32. doi: 10.1176/ajp.148.7.929.


The cognitive function scores and subjective memory complaints of eight patients who had each received more than 100 treatments with bilateral modified since wave ECT were equivalent to those of matched patients who had never received ECT. The results suggest that patients given many ECT treatments over several courses do not manifest measurable cognitive impairment at long-term follow-up.
