No, there is no scientific evidence to suggest that niacin deficiency causes autism. Autism spectrum disorder (ASD) is a complex neurodevelopmental condition influenced by genetic and environmental factors. Niacin deficiency, also known as pellagra, primarily leads to symptoms related to the skin, digestive system, and nervous system, such as dermatitis, diarrhea, and dementia, but it is not linked to causing autism. Research in autism focuses largely on genetics, brain structure and function, and early developmental cues, rather than deficiencies of specific vitamins like niacin.
