How brain injury can lead to post-traumatic stress disorder

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.

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.

Rare sleep disorder common among veterans with PTSD

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.

Peptide hydrogels could help heal traumatic brain injuries

A newly developed peptide hydrogel could help repair some of the damage caused by a traumatic brain injury. In rat models, the hydrogel improved the survival of brain cells, resulting in twice as many neurons at the injury site than in the control rats with TBI. Researchers reported new blood vessels also grew.

How a side hit to the head could damage brain and lead to concussion

Side impact to the head can lead to rotational accelerations what cause mechanical vibrations to concentrate in the corpus callosum and periventricular region of the brain. Trauma to the side of the head can lead to concussions.

Nearly three-quarters of traumatic brain injuries in under-19s caused by consumer products

A new study identifies specific consumer products related to non-fatal brain injuries in children between the ages of 0 to 19. For infants, the leading cause of head injury is falling from beds, while in the teenage group, sporting equipment was the leading cause of TBI.

Brain injury common in domestic violence

Many survivors of domestic violence are likely to have experienced repeated head injuries and oxygen deprivation. The injuries resulted in memory loss, anxiety, and visual problems. Of the 49 people interviewed for this study, 81% report being hit in the head by their partner, while 83% report strangulation events.

Hidden Consciousness Detectable with EEG Just Days after Brain Injury

Researchers detected brain waves indicative of 'hidden' consciousness in 15% of patients with TBI four days after the injury occurred. Among those patients, 50% improved and were able to follow verbal commands before being discharged from hospital compared to just 26% who did not show signs of hidden consciousness.

People with traumatic brain injury, who often lose empathy, can regain it with treatment

Many people who experience traumatic brain injury report a loss of empathy following their injury. Researchers consider how to reconnect those who have a TBI with their feelings of empathy and emotional recognition.
