Can sleep deprivation cause ADHD? I never linked the two, but Vatsal G. Thakkar did in a New York Times opinion piece. Thakkar is a clinical assistant professor of psychiatry at NYU School of Medicine in New York and an ADHD sufferer. Or is he? Thakkar was misdiagnosed with ADHD. He found an underlying sleep issue that, when properly addressed, removed all of his ADHD symptoms.
