The word dementia describes a set of symptoms that may include memory loss and difficulties with thinking, problem-solving or language. Dementia is caused when diseases, such as Alzheimer’s disease or a series of strokes, damage the brain. Dementia is progressive, which means the symptoms will gradually get worse. In most cases, there is no way to cure the diseases that cause dementia. However, there are drugs and treatments available that may help alleviate some of the symptoms.
