Other dementias

“Other dementias” resemble Alzheimer’s disease in that they also involve a progressive degeneration of brain cells that is currently irreversible. There are many different types of dementia, although some are far more common than others.

A small percentage of dementias are reversible, occurring as a secondary development in treatable conditions. Toxic reactions to prescription or over the counter medications are the most common cause of reversible dementia. Others include dietary or vitamin B12 deficiencies, infections, tumours, alcoholism, inflammatory states, hormonal dysfunction, environmental toxins, drug abuse, and depression.
