The persistence of electroconvulsive therapy-induced changes in the electroencephalogram
The Journal of Nervous and Mental Disease
|April 1, 1980
Summary
Electroconvulsive therapy (ECT) can cause temporary EEG abnormalities, primarily slow wave activity. These changes usually resolve within months, though more treatments may prolong them.
Area of Science:
- Neuroscience
- Clinical Electrophysiology
Background:
- Electroconvulsive therapy (ECT) is a medical treatment.
- Understanding its effects on brain activity is crucial.
Purpose of the Study:
- To review the literature on electroencephalogram (EEG) changes following ECT.
- To assess the degree and duration of these EEG abnormalities.
Main Methods:
- Literature review of studies on ECT and EEG.
- Analysis of reported electrophysiological dysfunctions.
Main Results:
- Generalized slow wave activity is the most common EEG abnormality post-ECT.
- These EEG changes typically resolve within weeks to months.
- Prolonged alterations can occur, especially with higher numbers of ECT treatments.
Conclusions:
- ECT-induced EEG slowing is usually transient.
- Factors like treatment dosage may influence the persistence of EEG changes.

01:24Epilepsy and Seizures: Overview
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

01:30Electroconvulsive Therapy
Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early years,...
