What age does Alzheimer’s start?


Alzheimer’s disease is a progressive brain disorder that affects memory, thinking, and behavior. It is the most common cause of dementia, a general term for a decline in cognitive ability severe enough to interfere with daily life.

The age at which Alzheimer’s disease starts can vary, but it most commonly affects individuals who are 65 years of age or older. This is known as late-onset Alzheimer’s disease, which accounts for the majority of cases. However, early-onset Alzheimer’s disease, which is relatively rare, can begin as early as the 30s or 40s.

The risk of developing Alzheimer’s disease increases with age, and the prevalence of the disease rises sharply after the age of 65. However, it’s important to note that not everyone who reaches old age will develop Alzheimer’s disease, and there are also cases of individuals who develop Alzheimer’s disease before the age of 65. Risk factors for Alzheimer’s disease include age, genetics, family history, certain lifestyle factors, and other medical conditions. It’s always best to consult with a healthcare professional for accurate diagnosis and information about Alzheimer’s disease.
