Causes of Dementia

There can be many causes of dementia. It generally involves some level of brain cell death, often due to a neurodegenerative disease, which is a process that occurs over time. What can sometimes be unclear, however, is whether the brain cell death causes the dementia or is caused by it. Other potential causes of dementia can include head injury, a brain tumor, or a stroke. There could be a prion disease, which results from infection by a protein-based particle. Finally, there are several reversible factors, such as medication interactions, vitamin deficiencies, depression, or thyroid abnormalities, that can temporarily display signs of dementia.Next
