The motor symptoms in "psychiatric disorders" are clearly not mental processes - memetic processes - but reflect the underlying disorder of executive function, broadly defined as human will. The negative effects on mental function, or "meme function", are just a symptom of disturbed executive function. Psychiatry models all of this in reverse, executive dysfunction is caused by mental disorder, rather than the other way around, and it does so because it has to conform to a "generatio spontanea" type of cause and effect, ultimately a result of pecking order bias and cowardice. Psychiatry is not a science. The truth will set you free.
