The medical body consists of interdependent systems, "causation" is a seriously complicated issue if we are talking about medical negligence. The medical personnel or authorities involved might argue that their procedure and or treatment was not the cause of the injury but that it was instead the ill affect of a medical condition the patient was going through.
IF a patient wants to claim for medical  malpractice for any medical negligence, in that case he or she has to prove  main three points. First one is that the medical professionals had a duty and  full responsibilty to provide a certain rules and regulations and   standard of care, which was not folloed and which lead to injury etc. And the  second thing is that the patient suffered an injury be it physical, mental or  othersie and the third and final thing to prove is that the injury was actually  caused and was the result of the alleged medical negligence or carelessness.
Know do you know that "standard of  care" varies from state to state. Some laws restrict the medical standard  to be followed be the physicians in the same area of the country, while others  states may extend the medical standard to doctors on a countrywide level. lets  says for an example, a brain surgeon will be held to certain standard of other  surgeons in the same field. If he or she acted in a way that differs from the  way most brain surgeons would have acted in similar circumstances, that surgeon  may be found to have been medically negligent.
It is not only the Physical injury but  Psychologists and psychiatrists can also be sued for medical negligence,  although these types of cases are much more difficult to prove because not only  are the injuries non-physical, but causation is particularly complex.
In any type of case, the attorneys  assigned by the physicians' malpractice insurance company will likely try to  argue that the injury was not caused by medical negligence.
