Dementia is a term used to describe symptoms that are associated with loss of memory and cognitive functions. When a person is afflicted with dementia, they can have trouble concentrating and remembering things. At later stages, some people lose the ability to properly care for themselves and are dependent on those around them for even their most basic needs. One form of dementia is Alzheimer's disease. It is also one of the most studied forms of dementia. Most forms of dementia worsen with time and are sometimes irreversible. Becoming educated about dementia and recognizing the signs and symptoms can be helpful if a loved one is exhibiting behavior that is not characteristic of them.
While much is continuously being learned about dementia, some of its causes include strokes, head injuries, and various diseases and infections. Certain forms of dementia can be reversible. The two most common types of dementia are Alzheimer's disease and vascular dementia, which is also referred to as multi-infarct dementia.
Some symptoms of dementia are memory loss, personality changes, difficulty performing familiar tasks, disorientation and the inability to make good decisions. People suffering from dementia may misplace things and be unable to find them later. They may develop mood swings that change quickly and without warning. They may seem confused or become lost in areas that were once familiar to them. Over time, symptoms often progress.
Once a diagnosis of dementia has been made, the doctor will work with you to find treatment options that fit your situation. While many forms of dementia are irreversible, there are medication and other treatment options, such as behavioral therapy, that can slow down the process.
Research is continually uncovering new possible causes and treatments for dementia. While there aren't yet any clearly defined ways to prevent dementia, some steps that can be taken to minimize your risk are to maintain a healthy lifestyle that includes a nutritional diet and regular exercise.
