Scientists have discovered how electroconvulsive or electric shock therapy - a controversial but effective treatment - acts on the brains of severely depressed people and say the finding could help improve diagnosis and treatment of mental illness. 略 In a study published in the Proceedings of the National Academy of Sciences (PNAS) journal they found ECT appears to turn down overactive connections between parts of the brain that control mood and parts that control thinking and concentrating. 略
In a study published in the Proceedings of the National Academy of Sciences (PNAS) journal they found ECT appears to turn down overactive connections between parts of the brain that control mood and parts that control thinking and concentrating.
"For the first time we can point to something that ECT does in the brain that makes sense in the context of what we think is wrong in people who are depressed."
He said the results also chime with a study Nutt published in January which found that psilocybin, the active ingredient in the psychedelic drug known as magic mushrooms, also disrupts this network of connections and may also be effective in treating severe depression.
He said the new method could also be applied to a wide range of other brain disorders such as schizophrenia, autism, or dementia, and "may lead to a better understanding of the underlying disease mechanisms and the development of new diagnostic tools."

"Our key finding is that if you compare the connections in the brain before and after ECT, ECT reduces the connection strength," he said in a statement.
