The brain may need iron for healthy cognitive development

Iron levels in the basal ganglia steadily increase throughout development and, in two sub-regions, continue to increase into adulthood. Decreased levels of iron in the putamen was correlated with impaired cognitive performance involving reasoning and spatial processing. Findings suggest the brain requires iron for healthy cognitive development. Read More

Brain differences detected in children with depressed parents

The right putamen, a brain area linked to reward, motivation, and feelings of pleasure, is smaller in children with a genetic risk factor for depression. Previous studies implicated reduced putamen volume with anhedonia, which is often associated with depression, suicidal behaviors, and psychosis. Read More

Study identifies brain injury as a cause of dementia in some older adults

MRI neuroimaging can distinguish between memory loss caused by Alzheimer's disease and traumatic brain injury. Using new image analysis software, researchers discovered TBI causes the most amount of damage to the ventral diencephalon, a brain area associated with memory and learning, and the least amount of atrophy to the hippocampus, a brain region most impacted by Alzheimer's.

Gene variants influence size of brain stem and other structures

Researchers identified 48 common genetic variants that appear to play a role in the size of the brainstem and other subcortical structures. Forty of the variants were novel. The findings also revealed 199 genes related to the variants which regulate brain development and susceptibility to neurological disorders. Read More

Altered Brain Activity in Antisocial Teenagers

Neuroimaging reveals lower activation in the dorsolateral prefrontal cortex and angular gyrus in teenage girls with conduct disorder. Findings suggest that a reduction in prefrontal brain regions and functional connectivity during effortful emotional regulations contribute to behaviors associated with antisocial behavior in teenage girls.
