Dementia is a common disease in the elderly population that causes disability and increases mortality. It is a significant public health problem because of the burden the disease places on the health care system and the caregivers of the demented person. There are different environmental and biological characteristics which have been suggested to be a causal factor for developing dementia. One that is very controversial and has received a lot of media attention in North America is head injury. In this proposed study, we will be determining if a history of traumatic brain injury is associated with development of dementia or cognitive decline in a population of Danish twins. By examining this question in twins, we are able to control for potential genetic-related causal factors.
