Dementia is not a disease itself, but rather a group of symptoms that may accompany certain diseases or conditions. Dementia is the loss of mental functions, such as memory, thinking, and reasoning that is severe enough to interfere with a person’s daily functioning. Dementia is irreversible when caused by disease or injury, but might be reversible when caused by drugs, alcohol, hormone or vitamin imbalances, or depression. Therefore, it is very important to evaluate dementia symptoms comprehensively, so as not to miss potentially treatable conditions. Most types of dementia can't be cured, but doctors will help manage the symptoms.Treatment of dementia symptoms may help slow or minimize the development of symptoms. We will talk about the medical treatments for dementia throughout this class.
