Although most dementias are not curable, there are many positive things you can do to control the symptoms of dementia, including medication, home safety, and care management techniques. This can go a long way toward helping the person still live a meaningful life - to best of their own, unique ability.

Dementia is a brain disorder that seriously affects a person's ability to carry out daily activities. They lose their ability to solve problems and maintain emotional control, and they may experience personality changes and behavioral problems, such as agitation, delusions, and hallucinations.

Symptoms of dementia can be caused by various conditions, including Alzheimer's disease, vascular dementia (or stroke), Lewy body dementia, frontotemporal dementia (FTD), Huntington's disease, and Creutzfeldt-Jakob disease.

Reversible conditions with symptoms of dementia can be caused by a high fever, dehydration, vitamin deficiency, and poor nutrition, bad reactions to medicines, problems with the thyroid gland, or a minor head injury. Medical conditions like these can be serious and should be treated by a doctor as soon as possible.
