Which outcome completes the four Ds of pellagra?

Explanation:
Pellagra is classically described by four outcomes: dermatitis, diarrhea, dementia, and death. The last one completes the quartet, representing progression to severe niacin deficiency if not treated. While severe disease can involve extensive neurological or other complications, coma, seizures, and blindness are not the standard fourth component of the four Ds.
