Pellagra is associated with which symptoms referred to as the "3 Ds"?

Pellagra is a nutritional deficiency condition primarily caused by a lack of niacin (vitamin B3) and is most famously characterized by the "3 Ds": Diarrhea, Dermatitis, and Dementia. Each of these symptoms corresponds to a significant impact on the body as a result of this deficiency.

Diarrhea results from the malabsorption and gastrointestinal disturbances linked to the lack of niacin. Dermatitis is noted for its distinctive skin lesions typically occurring in sun-exposed areas, leading to symptoms such as redness, scaling, and sometimes a darker pigmentation. Dementia illustrates the neurological impact of niacin deficiency, which can result in cognitive decline, confusion, and other mental health issues.

While the other options present combinations of symptoms, they do not correspond with the recognized clinical manifestations of pellagra. Thus, the answer that accurately reflects the triad of symptoms associated with this condition is indeed the one that lists Diarrhea, Dermatitis, and Dementia as symptoms of pellagra.
