What Is Alzheimer’s?
Understanding Alzheimer's and Dementia
Alzheimer’s disease is the leading cause of dementia, a broad term that describes memory loss and other cognitive impairments severe enough to affect daily life. It accounts for 60-80% of all dementia cases, making it the most common form of this condition.
While Alzheimer’s is often associated with aging, it is not a normal part of growing older. The most significant risk factor is age, with the majority of cases occurring in individuals aged 65 and older. However, Alzheimer's can also affect younger individuals, known as younger-onset or early-onset Alzheimer's, which occurs before age 65. Younger-onset Alzheimer’s can present in any stage of the disease—early, middle, or late.
The Progressive Nature of Alzheimer's
Alzheimer’s is a progressive disease, meaning symptoms worsen gradually over time. In the early stages, memory loss may be mild, but as the disease progresses, individuals may lose the ability to communicate or engage with their surroundings. The average lifespan after diagnosis is 4 to 8 years, though some may live as long as 20 years, influenced by overall health and other conditions.
Understanding Alzheimer’s and its impact can help families better navigate the journey of care and support.
