Final answer:
Modern psychosurgery is less common than early lobotomies and utilizes more precise techniques, targeting specific brain areas.
Step-by-step explanation:
Compared to early, crude lobotomies, modern psychosurgery is performed much less often. In the past, the prefrontal lobotomy was a common procedure to treat various psychiatric disorders by severing the connections between the prefrontal cortex and other regions of the brain.
This was thought to be necessary for patients with potentially uncontrollable behavior, mood disorders, and psychoses. Modern psychosurgery, when performed, uses more precise techniques and targets specific areas of the brain.
It is no longer a widespread treatment due to the development of antipsychotic drugs and the recognition of the severe and often detrimental effects lobotomies had on personality and cognitive function.
Lobotomies were once used to treat uncontrollable behavior and serious mental disorders, but have been largely replaced by medication and other therapies.
