title: Cessation of long-term naltrexone administration: longitudinal follow-ups.
abstract: Longitudinal follow-ups of the cessation of long-term Naltrexone administration (1 year of drug therapy) were conducted with a young woman (in her early 30s) with profound mental retardation who had previously displayed dramatic decreases in her self-injurious behaviors (SIB) both during, and for a period of at least 6 months following termination of drug treatment. After 2 and 4 years, post-Naltrexone therapy, the subject continued to exhibit near-zero rates of SIB episodes despite significant turnovers in her direct care staff by the 2-year follow-up, and changes in her physical/living environment and fellow residents by 4-year follow-up. These findings provide further support to the idea that long-term Naltrexone administration may result in highly durable reductions in SIB long after treatment ends and argue against certain aspects of the subject's environment affecting her rates of SIB significantly. These results are discussed in light of the endogenous opiate system theories of SIB. A functional analysis and discussion of the effectiveness of behavioral treatments for her few remaining SIB episodes are also provided.
