Dementia

There is no single definition for the word dementia. It is used to describe a group of symptoms that can be caused by a variety of disorders that affect the brain. A person with dementia has difficulty solving problems and has impaired intellectual function which disrupts normal activities and relationships. In addition, a person with dementia may have a hard time maintaining emotional control and he/she may go through severe behavioral problems and personality changes.

There is some treatment for certain progressive forms of dementia, such as Alzheimer's disease, among others. These medicines do not reverse brain damage and do not "stop" the disease, but can slow down the disease's progression.

There are also a number of treatments for "milder" forms of dementia, and in certain cases, the dementia can even be reversed. Those with advanced dementia will require 24-hour supervision to prevent them from hurting themselves/others. In addition, they may need help with daily activities, including the following: eating, bathing, and dressing.
