While impact on the brain at the same site of injury to the skull is the ...
The brain can be deprived of oxygen with as little as 4.4 pounds of pressure and can cause loss of consciousness in just ten seconds. When hypoxia begins, permanent brain damage can occur within ...
Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...
Unfortunately, doctors “don’t really know the cause of this,” he adds. It's possible that sundowning in dementia patients is caused by a combination of hormonal changes, brain deterioration ...
Closed-head injury is a type of traumatic brain injury in which the skull and dura mater remain intact. Closed-head injuries are the leading cause of death in children under 4 years old and the most common cause of physical disability and cognitive impairment in young people.
Research in brain damage as a result of repeated head injuries began in the 1920s, at which time the condition was known as dementia pugilistica or "boxer's dementia", "boxer's madness", or "punch drunk syndrome". [1] [3] It has been proposed that the rules of some sports be changed as a means of prevention. [1]
