These medications are sometimes used to treat the dementia associated with Lewy body disease.

However, many people do not improve at all to medication or improve only a little.

People with dementia that cannot be reversed need care from doctors, nurses and social workers. This care can take place anywhere, including in a hospital, at home, in an assisted-living center, or in other types of facilities. Depending on the cause of the dementia, several specialists may be involved in care, including neurologists, psychologists, psychiatrists or geriatric doctors. Important aspects of care include:

• Familiar surroundings, people and routines, because too much change can cause confusion and agitation

• Bright, active environments to help focus the person's attention and keep him or her oriented to the environment

• Safe environments so that the person cannot be hurt or get lost if he or she wanders away

• Physical exercise to improve balance and general good health

• Appropriate therapies, including music, art and occupational therapy, to provide stimulation and improve control of muscles
