Alzheimer’s disease (AD) is the most common form of dementia among older people. Dementia is a brain disorder that seriously affects a person’s ability to carry out daily activities.

As the disease progresses, people may not recognize family members or have trouble speaking, reading or writing – eventually requiring total care.
