Which is a cognitive effect of lead exposure?

• A. Rash
• B. Drowsiness
• C. Memory loss - concentration problems
• D. Headache

Answer: (C)

Lead exposure can impair brain function, leading to cognitive changes. The most characteristic cognitive effects are memory loss and problems with concentration, reflecting difficulties with attention, working memory, and information processing. This neurotoxic impact arises because lead disrupts neural signaling and the brain circuits involved in memory and focus. Rash is a skin symptom, not related to cognition. Drowsiness is a non-specific symptom of fatigue and does not specifically describe cognitive impairment. Headache can occur in various conditions and isn’t as clearly tied to cognitive performance as memory loss with concentration problems. Therefore, memory loss and concentration problems best represent a cognitive effect of lead exposure.
