Which of the following is listed as a symptom of manganese toxicity?

• A. Headache
• B. Parkinson-like abnormalities
• C. Both Headache and Parkinson-like abnormalities
• D. None of the above

Answer: (C)

Manganese toxicity can affect the nervous system in ways that include both motor and nonspecific symptoms. The parkinson‑like abnormalities come from manganese accumulating in the basal ganglia, leading to tremor, rigidity, slowed movement, and gait difficulties. Headache, while nonspecific, can also occur with manganese exposure as part of central nervous system effects. Because both types of symptoms can be associated with manganese toxicity, the option that includes both headache and Parkinson‑like abnormalities best reflects how manganese toxicity can present clinically.
