Dementia is a word for a group of
symptoms caused by disorders that affect the brain. It is not a specific
disease. People with dementia may not be able to think well enough to
do normal activities, such as getting dressed or eating. They may lose
their ability to solve problems or control their emotions. Their
personalities may change. They may become agitated or see things that
are not there.
Memory loss is a common symptom of dementia. However, memory loss by itself does not mean you have dementia. People with dementia have serious problems with two or more brain functions, such as memory and language.
Many different diseases can cause dementia, including Alzeimerand stroke. Drugs are available to treat some of these diseases. While these drugs cannot cure dementia or repair brain damage, they may improve symptoms or slow down the disease.
