Amateur boxers, specifically those who boxed during their youth, are twice as likely to develop Alzheimer's disease than those who didn't.
White matter hyperintensities were more common in athletes who played more contact sports or had more head injuries and concussions during their sporting careers.
Blocking substance P following a head injury can prevent tau protein tangles from forming in the brain and lower the risk for CTE and other head injury associated dementias.
Military and law enforcement personnel who are routinely exposed to low levels of blasts, such as from high-caliber firearms while training, have higher levels of biomarkers associated with TBI.
Combining brain scan images with machine learning, researchers identified a number of brain changes following TBI that share similarities with Alzheimer's disease. The findings add to the growing body of evidence that the two conditions follow the same trajectories.
Birth control pills high in progesterone might be a new weapon in the fight against concussion in women. Researchers found that during the menstrual cycle, when progesterone levels were higher, women reported less concussion-related stress. Post-concussion stress reduction is a sign of recovery from a head injury. Progesterone is also linked to increased blood flow to the brain.
In veterans who suffered a TBI, lack of sleep was associated with enlarged perivascular spaces and an increase in post-concussive symptoms.
A single head injury can increase the risk of developing dementia, especially in women. Suffering more than one head injury increases the risk further, a new study reports.
Altered microRNA levels in a person's saliva can help determine if they have experienced a recent concussion. The new saliva test is a cheap and non-invasive method for the identification of concussion.
