About every month or two....there's some story in the German news....some attack on a German....with a knife involved (usually). If you follow the story over the next couple of months....the German judge has 'bound' the guy over to a mental clinic for a 30-day exam. With one exception that I know of....the vast majority of endings end up with the clinic director stamping the guy paranoid schizophrenic.
The letter goes to the judge, and a month or two later....the charges are dismissed and the guy is 'bound' (in a permanent way) to some German mental clinic. That's usually the end of the story.
Over the past month....I've put a couple of hours in...reading up on schizophrenia.
First....how it develops. It's basically a mix of genetics, brain chemistry, and environmental triggers. You could live in a pretty low-key/low-stress situation and marginally ever show schizophrenia. The more stress you mix in....the more likely of a uncontrolled situation.
Second....there is NO real test to determine your level of schizophrenia. You can run blood and urine tests to check for drugs, alcohol, or other chemical imbalances. You can run imaging tests (MRI or CT scans) and EEGs (brain activity tests) to rule out brain injuries, strokes, tumors, or epilepsy.
I worked with a guy who'd had a stroke....over the course of three months....he developed full-blown schizoprenia....to the level that you couldn't trust the guy.
Third, you could survive with light schizophrenia.....keeping to a zero-drug lifestyle, and NO alcohol. The minute you add to your lifestyle....your odds increase.
Fourth....genetics plays a role. If your dad or mom had it.....higher the probability that you have it.
So I've come to the reality....yeah, there probably are hundreds of 'new-residents' of Germany with schizophrenia....adding alcohol/drugs to their lifestyle....hearing 'voices' and are not in control of themselves.
Resolving this trend? I've come to the point....you can't really fix this.
I also believe.....after five to ten years of holding some guy in a mental clinic....under very tight controls (no booze/no alcohol)....the management folks will eventually sign off on some release form....going to a German judge to release the 'safe' guy. Naturally....a month or two into freedom....he'll find temptation (booze/alcohol), and buy a knife. You know the scenario.
The odd end-point? Well...the schizophrenia guy would be fairly safe....in a zero-alcohol/zero-drug landscape....like in the 'old' country. But in Germany....he can never be truly safe.
