Quetiapine Reduced Childhood Mania, Especially in Those with Thicker Frontal Temporal Regions

white matterIn a symposium at the 2019 meeting of the American Academy of Child and Adolescent Psychiatry, researcher Melissa P. Delbello reported that six weeks of treatment with either lithium or quetiapine was effective in childhood mania, but quetiapine had a higher response rate of 71% versus 46% for lithium. Delbello found two types of structural changes on functional magnetic resonance imaging (fMRI). Some children had thicker frontal temporal regions, while others had thinning in these areas. The first group of patients had a 100% response to quetiapine, but only 53% of the second group responded to quetiapine.

In contrast, other researchers have found lithium superior to quetiapine. Vivian Kafantaris showed that patients who respond well to lithium show improvements in white matter abnormalities. Michael Berk and colleagues found that a year on lithium was superior to quetiapine on all measures including cognition and brain imaging in patients having their first episode of mania.
