There are many disorders that are linked to brain. Many of them are still unknown to the public’s. Being a TMS therapist I think no disorder is scary because almost all of them are curable. Even these six disorders have cures as well. Problem with people is, the loved ones and the patients usually do not take their mentality seriously such as depression and any other pressure to brain. That can harm the mentality. Therefore, I would say that never be uncaring about your most important part of the body.
