Which progressive brain disease is primarily associated with memory loss?

• A. Parkinson's disease
• B. Alzheimer's
• C. Dementia
• D. Multiple sclerosis

Answer: (B)

Alzheimer's disease is primarily associated with memory loss due to its impact on brain cells and their connections. It is a progressive neurodegenerative disorder that typically starts with mild memory loss and can eventually lead to more severe cognitive decline. In Alzheimer’s, the brain undergoes changes, including the buildup of amyloid plaques and tau tangles, which disrupt communication between neurons, leading to the loss of functions related to memory, reasoning, and other cognitive processes. While dementia is a broad term that encompasses a range of symptoms affecting memory and cognitive abilities, including Alzheimer's as one of its types, the question specifically points to the disease most directly aligned with memory loss as a primary symptom, thus making Alzheimer's the stronger candidate. Other options like Parkinson's disease and multiple sclerosis primarily involve other motor and systemic symptoms, and while they may lead to cognitive impairment later in the disease, they do not primarily manifest through memory loss like Alzheimer's does.
