Personality change, depression and anxiety are also common. Psychosis may occur in more advanced cases. 4 million Americans have AD now. Up to 14 million could have AD by 2050 if current trends continue. AD is the 3 rd most expensive disease in total cost, behind cancer and heart disease.
Early diagnosis is important to maximize treatment options.
If you suspect that a relative has dementia, see a geriatric specialist. A growing body of research shows that genetic mutations play a role in AD, such as amyloid plaques which choke neurons from the outside and neurofibrillary tangles which disrupt cell function from the inside. Each of us inherits one of three APOE genes from each parent. Genetic testing for rare familial forms of AD can be helpful, but testing to learn your APOE type is not recommended as yet. Having the other combinations doesn't mean that you won't get AD either.
