Has the Catholic Church issued standing instructions on caring for clergymen with psychological disorder?

In separate startling incidents, two Parish Priests of Roman Catholic Church of India reportedly gave up their life recently after having undergone treatment for psychological condition. In many parishes, the priests lead isolated life and are prone to suicidal tendency in case they have psychological disorder. Such incidences could have been avoided if the priests were withdrawn from the parish and kept in community life under observation. My question is: Has the Catholic Church issued any standing instructions to Bishops in order to stave off such unfortunate incidents?
