While there's some truth here, medical diagnosis and treatment can be really hard. People have weird habits, weird diets, are exposed to weird chemicals in small amounts over extended periods of time, etc. There are all kinds of genetic factors where something can be really minor for most people and debilitating for others. There are all kinds or problems or diseases that people can have, and there can be weird combinations that interact or provide an overall confusing array of symptoms. And it's all mixed up with the patient's brain, which may be exacerbating or compensating in all kinds of ways (psychologically or through behaviors that the patient develops).
