Conclusions
This study suggests that decreases in hippocampal [3H]pirenzepine binding in subjects with schizophrenia are most likely associated with widespread changes in expression levels of the M4 receptor. These data further implicate the hippocampal formation in the pathology of schizophrenia

You haven't read many scientific papers have you? Vague wording in conclusions are the norm.
At any rate, you asked for any cadaver study that provided evidence that there was a pathophysiology to psychiatry, and I provided it for you after a whopping three second google search.
The diagnosis of mental disorders is often believed to be more difficult than diagnosis of somatic, or general medical, disorders, since there is no definitive lesion, laboratory test, or abnormality in brain tissue that can identify the illness. The diagnosis of mental disorders must rest with the patients reports of the intensity and duration of symptoms, signs from their mental status examination, and clinician observation of their behavior including functional impairment. These clues are grouped together by the clinician into recognizable patterns known as syndromes. When the syndrome meets all the criteria for a diagnosis, it constitutes a mental disorder.

Once again, I have already told you that psychiatry deals entirely in clinical diagnosis due to the fact that there are no tests currently available to provide a lab value for the diagnosis. I have never met a psychiatrist (BTW, I am not a psychiatrist) who has stated otherwise.
This quote says exactly what I have stated.
Again, I have never claimed that there is a workable test and safe test that psychiatry can use to make a diagnosis. You have either misunderstood me or are misrepresenting my words when you claim I have. Furthermore, I also agree that the pathophysiology of even the most discrete of conditions (i.e. schizophrenia) has not been fully established.
Where we differ is that you don't think it is possible to discern a pathophysiology or establish a test at some point in the future, and I do.
Again, your fundamental problem is that you are only content to point out holes in psychiatry without offering any workable alternative. When pressed for an alternative, you can only resort to anecdotes and personal opinion, none of which has ever met any sort of scientific scrutiny (while constantly bitching about how psychiatry is not "science"). This is somewhat akin to the people that argue against evolution by pointing out its flaws without offering any scientifically workable counter-proposals.
Finally, if you think psychiatrists don't study the CNS or that the study of the brain is limited to the field of neurology, you are clueless.
In fact, I provided (and you read) one such study on this thread. Though, I have noticed that you simply ignore items that are inconvenient for your.
