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.
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.
Over 50% of patients with mild traumatic brain injury reported their sense of smell was diminished following concussion. The effect does not appear to be long term.
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.
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.
Low-field magnetic stimulation (LFMS), a new, non-invasive repetitive transcranial magnetic stimulation technique, may help improve neurological symptoms following concussion.
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.
People with bipolar disorder have higher incidences of Parkinson's disease than those without the psychiatric condition. Manic and depressive episodes were associated with an elevated risk of developing Parkinson's disease.
Neuroimaging study reveals veterans who suffered a mild traumatic brain injury (mTBI) have higher levels of fast, high-frequency gamma waves in the prefrontal and posterior parietal lobes, areas of the brain associated with consciousness, attention and problem-solving.
Neuroimaging helps researchers observe what happens in the brain as a person is rotated. The study, which gives insight into how the brain moves after the head stops moving, also provides critical information for advancing studies of TBI.
Mimicking effects of the ketogenic diet with a drug called 2-DG reduced cell excitation and epileptic activity in mouse models of post-traumatic epilepsy. 2-DG may have the potential to restore network function following TBI, reducing the risk of epilepsy associated with head injuries. The findings may have positive implications for people who developed post-traumatic epilepsy, suggesting a change in diet could help alleviate some symptoms.
Veterans with comorbid mild traumatic brain injury and PTSD had significantly greater amygdala volume compared to those with mTBI alone.
