Background:Although electroconvulsive therapy (ECT) causes no structural brain damage, recent studies reported altered brain perfusion acutely following ECT. This is in keeping with brain edema which was noted in animal experiments following electroconvulsive shock.Aim:This study examined alteration in magnetic resonance imaging (MRI) T2 relaxation time, a measure of brain edema, and its relation to therapeutic efficacy, orientation and memory impairment with ECT.Materials and Methods:Fifteen drug-naive consenting patients of major depressive disorder with melancholia (DSM-IV) received ECT as first-line treatment. MRI scans were done before the first ECT and at 2 hours after the second ECT. T2 relaxation time was measured bilaterally in thalamus, hippocampus, medial temporal lobes and dorsolateral frontal cortex by a blind rater.Results:Depression scores and memory scores were reduced significantly both after the second and fifth ECT. There was no change in T2 relaxation time after second ECT.Conclusion:The finding suggests that ECT does not produce demonstrable change acutely in brain parenchyma detectable by MRI scans.
Accidental awareness under general anesthesia (AAGA) is a well-known phenomenon. However, little literature exists in its relation to the psychiatric field, particularly within the electroconvulsive therapy (ECT) setting. This report explores the case of a 52-year-old woman that describes her own experience of AAGA during ECT. Relevant anesthetic details are also provided along with its possible implications in AAGA. The aim of this case report is to increase awareness among clinicians in regard to AAGA and its occurrence during ECT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
