Psychosurgery

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Electroconvulsive Therapy

Electroconvulsive 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...

Area of Science:

Neurosurgery
Epileptology
Pediatric Neurology

Background:

Hemispherectomy is a surgical procedure for intractable epilepsy in children.
It has evolved significantly since its initial description.
Indications include hemimegalencephaly, Rasmussen's encephalitis, Sturge-Weber syndrome, perinatal stroke, and cortical dysplasia.

Purpose of the Study:

To review the evolution of hemispherectomy techniques.
To analyze the outcomes and complications of hemispherectomy.
To discuss factors influencing success rates.

Main Methods:

Literature review of hemispherectomy procedures.
Analysis of historical and current surgical modifications.
Evaluation of reported outcomes and complications.

Main Results:

Hemispherectomy is highly successful in seizure reduction.
Modifications have decreased mortality and morbidity.
Hemimegalencephaly may increase morbidity and reduce success rates.

Conclusions:

Hemispherectomy remains a leading surgical option for pediatric intractable epilepsy.
Continued research is needed to identify outcome predictors.
Understanding pathology and surgical type is crucial for optimizing results.
