A head injury can cause dementia, according to researchers from Imperial College London. In patients who have suffered a concussion, doctors found in the brain of amyloid plaques. The same deviation characteristic of Alzheimer's disease.
In total the study involved nine people who have suffered traumatic brain injury severe or moderate severity.
In most cases, the cause of the injury was an accident. Many volunteers after the accident quickly came to his senses, but to return to the former concentration and quickness of mind was not at all. About it writes The Daily Mail.
Scientists have found a pattern: the stronger was the brain injury, the more severe plaques had been diagnosed. It is possible that damage to the nervous system acts as a start for irreversible changes related to dementia.
