Head Trauma Links to Dementia. Various physical traumas like brain injury, tumors, oxygen deprivation or exposure to heavy metals can also cause dementia. Dementia pugilistica, or boxer's dementia, is caused by repetitive trauma to the head, while post-traumatic dementia occurs after a single incident of brain injury. The dementia itself can be caused either by direct tissue damage or by swelling, infection or fluid collection.
TBI occurs when the brain is injured by an external force. TBI can occur either as a result of blunt force trauma or shock waves from a blast.
