Summary
Electroconvulsive therapy (ECT) effectively treats psychiatric disorders but is debated for causing brain damage. Current evidence shows ECT impacts brain structure and function, but does not prove it causes lasting brain damage.
Area of Science:
- Neuroscience
- Psychiatry
- Medical Ethics
Background:
- Electroconvulsive therapy (ECT) is a recognized psychiatric treatment.
- Concerns persist regarding ECT's safety, particularly its potential to cause brain damage.
- Defining and studying brain damage from ECT presents significant ethical and technical challenges.
Purpose of the Study:
- To review current evidence on whether electroconvulsive therapy (ECT) is associated with brain damage.
- To examine indirect methods used to assess ECT's impact on the brain.
Main Methods:
- Narrative review of existing literature.
- Analysis of studies using structural, functional, and metabolic neuroimaging.
- Inclusion of body fluid biochemical marker studies and cognitive follow-up assessments.
Main Results:
- Evidence indicates electroconvulsive therapy (ECT) demonstrably affects brain structure and function.
- No conclusive evidence currently supports the claim that ECT causes brain damage.
Conclusions:
- While ECT influences brain activity and morphology, current data do not substantiate claims of causing brain damage.
- Further research is needed to fully understand the long-term neurological effects of ECT.

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...

01:24Epilepsy and Seizures: Overview
950
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...

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...
