Neuroanatomical correlates of depression in post traumatic brain injury: preliminary results of a pilot study.

The authors present preliminary results from a pilot study on patterns of brain injury associated with incident major depression after traumatic brain injury (TBI). Brain metabolite ratios, regional brain volumes, and cognitive performance were compared between 10 subjects with incident major depression post-TBI and seven TBI patients without major depression. TBI-depressed participants performed poorly on tests of frontotemporal functioning, had lower choline/creatine and N-acetylaspartate/creatine ratios in the right basal ganglia and had lower regional brain volumes in the right frontal, left occipital, and temporal lobes.

Neuropsychiatric symptoms in dementia patients with and without a history of traumatic brain injury.

The authors aim to determine if a history of traumatic brain injury (TBI) assessed before dementia onset is associated with a higher risk of neuropsychiatric symptoms after dementia onset. A population-based incident series of people with dementia were assessed for TBI prior to onset of dementia and for neuropsychiatric symptoms after the onset, using the Neuropsychiatric Inventory. Participants with predementia TBI were more likely to exhibit disinhibition (12.

Predictors of new-onset depression after mild traumatic brain injury.

Mild traumatic brain injury (TBI) is the most common form of TBI. Most people recover after mild TBI, but a small percentage continues to have persistent problems, predominantly depression. There is, however, minimal literature on the risk factors associated with mild TBI depression.

Aggression after traumatic brain injury: prevalence and correlates.

Aggression after traumatic brain injury (TBI) is common but not well defined. Sixty-seven participants with first-time TBI were evaluated for aggression within 3 months of injury. The prevalence of aggression was found to be 28.
