Dementia (took out lating as maddness has negative conoations?) is a word that descibes a group of symptoms (this is what it is). These symtpoms can vary grately depeding on the cause, and can include memory loss, confusion and mood changes.

Dementia can be caused by a number of different diseases and conditions. The most common cause of dementia is Alzheimer's disease. Alzheimer's disease causes two thirds of cases of dementia. Other diseases that cause dementia are vascular dementia, dementia with Lewy Bodies, Frontotemporal dementia and Parkinson's disease. Rarer causes of dementia include CJD, HIV/AIDS, alcohol related dementia. Many people have two causes of dementia (for example Alzheimer's disease and vascular dementia) at the same time and this is termed mixed dementia.

The majortiy of people with demetia are over the age of 65. It can occur before the age of 65, in which case it is termed "early onset dementia".[1] xxx people world-wide have dementia, xxx of these have Alzheimer's disease. Around 40% of people with dementia do not recieve a formal diagnosis.

Especially in the later stages of the condition, affected persons may be disoriented in time (not knowing what day of the week, day of the month, or even what year it is), in place (not knowing where they are), and in person (not knowing who they, or others around them, are). Dementia, though often treatable to some degree, is usually due to causes that are progressive and incurable as observed in primary progressive aphasia (PPA).[3][4][5]

Symptoms of dementia can be classified as either reversible or irreversible, depending upon the etiology of the disease. Fewer than 10% of cases of dementia are due to causes that may presently be reversed with treatment. Causes include many different specific disease processes, in the same way that symptoms of organ dysfunction such as shortness of breath, jaundice, or pain are attributable to many etiologies.
