Brain blood flow helps treat depression

Israeli scientists have confirmed the usefulness of established molecular imaging approaches in the treatment of depression.

"Individuals in a depressed emotional state have impaired cerebral blood flow," said associate professor Omer Bonne at Hadassah-Hebrew University Medical Center in Jerusalem. "Clinical improvement in depression is accompanied by diverse changes in cerebral blood flow, according to whether patients are treated with medication or electroconvulsive treatment."

The researchers found antidepressant medicines normalized decreased brain blood flow in patients with depression, while electroconvulsive treatment was associated with additional decreases in blood flow.

"Currently, clinical psychiatry is based almost solely on subjective observer-based judgment," said Bonne. "Our findings suggest that objective imaging evaluations could support subjective clinical decisions."

The study appears in the August issue of the Journal of Nuclear Medicine.
