Soldiers who suffer traumatic brain injury are significantly more likely than those who suffer other serious injuries to be diagnosed with mental health disorders including PTSD, schizophrenia, and anxiety.
Growth hormone replacement therapy for those with mild traumatic brain injury helped improve cognition, anxiety, and depression while reducing fatigue and sleep disturbances.
Alzheimer's patients who used antipsychotics had a 29% increased risk of head injury and a 22% higher risk of TBI compared to others with the neurodegenerative disease who did not use the medications.
Analyzing previous studies, researchers have identified the effects of individual and environmental risk factors for suicide over a person's lifespan. The risk factors, researchers report, change throughout a person's lifetime.
Transplanting embryonic progenitor interneurons into the hippocampus of mouse models of TBI, researchers noticed the neurons migrated to the injury site and made new connections. Following treatment, memory improved and seizures were reduced.
Traumatic brain injury caused five times as many neurons in the amygdala to be active during white noise exposure in rats. Altered sensory processing within subcortical sensory-emotional networks following TBI impacts the facilitation of traumatic memory and may contribute to the development of PTSD.
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.
21% of veterans who experience PTSD or traumatic brain injury suffer from a rare sleep condition that affects less than 1% of the general population. The condition, REM sleep behavior disorder (RBD), is characterized by an impairment of sleep-related muscle paralysis, causing people to act out dreams during REM sleep. The uncontrolled actions often cause harm to the sufferer of their partners.
