A meta-analysis of cohort studies: Traumatic brain injury and risk of Alzheimer's Disease.

<h4>Introduction</h4>Recently, some epidemiological studies have reported that cognitive disorders in elderly people is accelerated with traumatic brain injury. But the causal relationship between traumatic brain injury and AD is still an area of controversy.<h4>Aims</h4>Our...
