Alzheimer's disease is a type of dementia that causes problems with memory, thinking and behavior. Symptoms usually develop slowly and worsen over time, becoming severe enough to interfere with daily tasks. Alzheimer's disease is the most common form of dementia, accounting for 60 to 80 percent of dementia cases.
Although the greatest known risk factor is increasing age, and the majority of patients aged 65 or above, it is not just a disease of old age. There are cases of younger onset, which often appears in 40s or 50s. Memory problems are typically one of the first signs of cognitive impairment, but decline in non-memory aspects are common such as word-finding difficulties, vision/spatial issues, impaired reasoning and judgement, etc. Later the patient may wander and get lost, repeat questions, have personality and behavioral changes. As memory and confusion get worse, patients begin to have problems recognizing family and friends. At last, patient's brain tissue shrinks significantly, leading to inability to communicate and may become a dependence on others for care.
Sadly, Alzheimer's disease cannot be cured. Current approaches aim to help patients maintain mental function, manage behavioral symptoms, and delay the progression of the disease. Worldwide research efforts continue to seek more effective and definitive therapies.
