If a defendant is deemed mentally ill, with a condition that has been diagnosed and treatable, that condition is usually monitored by a mental health unit within the probation office. If it was not put on the order, then the condition can be added so that it may be monitored. If the defendant can lead a "normal" life with proper medication, then the defendant will be violated for failure to comply. If the court monotors the defendant's mental health progress, then updated from the providing facility will be attained, blood draws to determine whether or not he adheres to recommendations and so on.
If it is determined that the defendant's mental health condition is a hinderance to compliance and nothing can be done to improve his condition to the point that he may be able to successfully navigate probation, the court will be made aware and alternative sentences will bw available.
