When you have a "diagnosis" from a "scientific discipline" that cannot be rigorously tested or diagnosed, it seems obvious it would be open to abuse in this manner.

If there were a blood test for crazy, it would be a little more difficult. Sadly, diagnosing illnesses of the mind is just educated guesswork, and will likely never rise to the level of science that most people assume.

There is evidence that MRI can be used to detect biological differences and that there is some genetic component as well. The two major challenges though are that these diseases are not "binary" but multivariate and that it's very difficult to collect enough data to explore that space. So it's certainly hard, but not impossible!
