The main symptoms of dementia are progressive memory loss, disorientation, and confusion. Sudden outbursts or embarrassing behaviour may be the first signs of the condition. Unpleasant personality traits may be magnified; families may have to endure accusations, unreasonable demands, or even assault. Paranoia, depression, and delusions may occur as the disease worsens. Irritability or anxiety gives way to indifference towards all feelings. Personal habits deteriorate, and speech becomes incoherent. Affected people may eventually need total nursing care.
Management of the most common
Alzheimer-type illness is based on the treatment of symptoms. Sedative drugs may be given for restlessness or paranoia. Drugs for dementia, for example donepezil, can slow mental decline in some people with mild to moderate Alzheimer’s disease (see acetylcholinesterase inhibitors).
