Adults suffering from lead poisoning can suffer from which of the following?

Adults suffering from lead poisoning can suffer from which of the following?

• A. Memory and concentration problems
• B. Hair loss
• C. Improved digestion
• D. Increased energy

Answer: (A)

Lead acts as a neurotoxin in adults, so its effects on the brain are a common and early consequence of exposure. This can show up as memory problems and difficulty concentrating, since neural signaling and cognitive processing are directly affected by lead. Other choices don’t fit the typical adult presentation: hair loss isn’t a usual symptom of lead poisoning, digestion isn’t improved (lead can actually cause abdominal pain and constipation), and increased energy isn’t something associated with lead exposure. So memory and concentration problems best reflect how lead poisoning commonly presents in adults.
