When I was a child my psychiatrists kept me in the hospital in the inpatient ward for over two years as a result of his fraudulent misdiagnoses as "borderline schizophrenic". The reason I suspect this is because no other psychiatrists heard of being borderline you either you are or your not it's what I was told.
Also, very shortly after that insurance companies stop paying for such an extensive inpatient treatment for reasons I'm not entirely aware of. But I suspect it's for the reasons that am talking about now.
Medical Malpractice Attorney
Texas medical malpractice claims are very hard to pursue now days because of "tort reforms" passed in 2003. A Texas plaintiff must be able to prove (1) a dramatic error occurred; (2) serious injury or death; and (3) a direct cause-and-effect link between the error and the injury. In cases involving misdiagnoses of mental conditions, the hard part is usually establishing enough financial loss to justify a claim. See, Texas laws cap damages relating to mental anguish, pain, and other non-economic damages. Those types of damage categories are greatly minimized under the tort reform scheme.
