An early sign of Alzheimer's disease is

• A. Seizures
• B. Forgetfulness
• C. Fever
• D. Aggression

Answer: (B)

Memory loss, especially trouble remembering recent events or conversations that disrupts daily life, is the hallmark early sign of Alzheimer’s disease. This reflects early destruction of memory-related brain areas like the hippocampus, leading to progressive short-term memory impairment before other functions are heavily affected. Seizures, fever, and aggression are not typical early indicators: fever points to illness, seizures are not common at the outset, and aggression tends to appear later as confusion and frustration increase. So the first clue most people notice is forgetfulness tied to everyday memory problems.
