Prognosis
The prognosis is best when identified early and treated aggressively. In these cases NMS is not usually fatal. In previous studies the mortality rates from NMS have ranged from 20%–38%, however in the last two decades mortality rates have fallen below 10% due to early recognition and improved management. Re-introduction to the drug that originally caused NMS to develop may also trigger a recurrence, although in most cases it does not.
Memory impairment is a consistent feature of recovery from NMS, and usually temporary, though in some cases, may become persistent.
