Which progressive neurological disease is known for causing memory loss in older adults?

Alzheimer's disease is renowned for its significant impact on memory, particularly among older adults. This progressive neurological disorder primarily affects cognitive functions, leading to challenges in remembering recent events, recognizing loved ones, and eventually, even basic daily tasks. The hallmark of Alzheimer's disease is the gradual deterioration of memory, which is often one of the first symptoms noticed by patients and their families. As the conditions progress, it can also affect language, thinking skills, and the ability to carry out simple tasks, but memory loss stands out as a defining characteristic.

While other options present neurological conditions, they do not primarily manifest with memory loss as their most notable symptom. Parkinson's disease primarily affects motor function and can also lead to cognitive impairment, but memory loss is not its central feature. Huntington's disease usually includes movement disorders and behavioral changes, but memory loss develops later in the disease progression. Multiple sclerosis may cause cognitive changes, but it is characterized more by physical symptoms and neurological deficits rather than the specific progression of memory loss associated with Alzheimer's.
