Tesla’s willingness to stay up during his childhood and adolescent age to read and learn everything that interests him is only the base problem. The second is possible brain damage from taking particle accelerator beams to the head. He did that intentionally for years. He had a wooden box sealed on a tripod and used it to stimulate extreme creativity, to help him fight fatigue, remove exhaustion, and the need for sleep. Although these were only speculations, this wooden box was probably filled with powerful x-ray tubes plus some fast electrons, a.k.a. Beta radiation. As a child, he almost died from Cholera twice, and he stopped infection by refusing to touch other people, shake hands, and insist on personally cleaning his plates and silverware at restaurants. This led him to the label of a germaphobe, and being a germaphobe can be a symptom of OCD. But the question that imposes is this the usual type of OCD, or maybe it had to do something with Beta radiation he took on the back of the head for years.
