Which condition is a progressive irreversible brain disease commonly associated with age?

• A. Alzheimer's disease
• B. Delirium
• C. Acute Renal Failure
• D. Mittelschmerz

Answer: (A)

The main idea is recognizing a progressive, irreversible brain disease that tends to be associated with aging. Alzheimer’s disease fits this description best. It’s a form of dementia marked by a gradual, unstoppable decline in memory and other cognitive abilities, followed by impairments in language, judgment, and daily functioning. As the disease progresses, neurons and brain connections deteriorate, with characteristic brain changes such as amyloid plaques and tau tangles contributing to the loss of neurons, especially in areas like the hippocampus and cortex. Age is the strongest risk factor, and while there are genetic influences, most cases occur in older adults. Delirium, by contrast, is an acute, fluctuating disturbance of consciousness and cognition that arises quickly and is usually reversible once the underlying cause (infection, medications, metabolic issues) is treated. Acute Renal Failure affects kidney function, not brain degeneration. Mittelschmerz is mid-cycle ovulation pain and has no relation to brain degeneration.
