Which disease is a progressive crippling disease that affects about 1 in 100 people over 60, with unknown cause and no cure?

• A. Alzheimer's Disease
• B. Parkinson's Disease
• C. Multiple Sclerosis
• D. Amyotrophic Lateral Sclerosis

Answer: (B)

Parkinson's disease best fits this description. It is a progressive neurodegenerative disorder that mainly affects movement, leading to symptoms like tremor, muscle stiffness, slowness of movement, and balance problems. It commonly begins in people around age 60 or older, and the number affected by age is often cited as about 1 in 100 over 60. The cause is not fully understood, and there is no cure, though therapies can help manage symptoms and improve quality of life. Alzheimer's disease is mainly a progressive cognitive decline involving memory and thinking, not primarily a crippling movement disorder, so it’s not the best match here. Multiple sclerosis usually begins in younger adults and is an autoimmune condition affecting the nervous system, which doesn’t align with the age-mostly description. Amyotrophic lateral sclerosis is a motor neuron disease that also affects movement but is far less common in the over-60 population and doesn’t fit the specified prevalence.
