INTRODUCTION: OCCUPATIONAL THERAPY IS A HEALTH PROFESSIONAL WITH MISSION OF IMPROVEMENT OF HEALTH AND WELLBEING OF CLIENTS. THEORETICALLY, PERSON IN INTERACTION WITH ENVIRONMENT PERFORM OCCUPATIONS THAT LEAD TO OCCUPATION PERFORMANCE. OCCUPATION PERFORMANCE RESULT IN PERSON ADJUSTMENT WITH ENVIRONMENT, AND SATISFYING OF NEEDS. USING OCCUPATION BASED INTERVENTIONS; OCCUPATIONAL THERAPISTS TRY TO IMPROVE OCCUPATION PERFORMANCE IN DIFFERENT DISORDERS. SLEEP IS A BASIC OCCUPATION AND DISTURBED SLEEP CAN DISTURB OCCUPATION PERFORMANCE. THEREFORE, RESEARCH ON THE RELATIVELY NEW FIELD OF SLEEP IN OCCUPATIONAL THERAPY, AND HOW OCCUPATIONAL THERAPISTS CAN IMPLEMENT THEIR INTERVENTIONS FOR SLEEP PROBLEMS IS NECESSARY.MATERIAL AND METHOD: THE SEARCH WAS PERFORMED ON THE GOOGLE SCHOLAR, PUBMED, ISI DATA BASE USING SLEEP PROBLEMS, OCCUPATIONAL THERAPY, OCCUPATION PERFORMANCE KEY WORDS. RELEVANT PAPERS WERE EXTRACTED AND ANALYZED.RESULTS: A LARGE BODY OF EVIDENCE SHOWS THAT SLEEP PROBLEMS CAN EFFECT ON OCCUPATION PERFORMANCE, AND THERE ARE SEVERAL INTERVENTIONS TO TREATMENT OF SLEEP PROBLEMS, ESPECIALLY INSOMNIA. COGNITIVE BEHAVIOR THERAPY, PHYSICAL ACTIVITY, AND MULTI TREATMENT INTERVENTIONS ARE AMONG THE TREATMENT. EVIDENCE ALSO SHOW THAT OCCUPATIONAL THERAPIST CAN APPLY THE INTERVENTIONS FOR CHILDREN WITH AUTISM SPECTRUM DISORDERS, OLDER ADULT, MENTALLY ILL PATIENTS, AND SO FOR CLIENTS IN VOCATIONAL REHABILITATION PROCESS. HOWEVER, THERE IS NO DIRECT EVIDENCE TO SUPPORT EFFICACY OF OCCUPATIONAL THERAPY INTERVENTIONS IN SLEEP PROBLEMS.CONCLUSION: SLEEP PROBLEMS CAN AFFECT OCCUPATION PERFORMANCE, AND OCCUPATIONAL THERAPIST SHOULD IMPLEMENT THEIR INTERVENTIONS TO IMPROVE SLEEP QUALITY AND OCCUPATION PERFORMANCE.MORE EDUCATION AND RESEARCH IN THIS NEW FIELD OF OCCUPATIONAL THERAPY IS NECESSARY.

INSOMNIA CAN BE PRIMARY OR SECONDARY TO OTHER PSYCHIATRIC OR MEDICAL CONDITIONS OR IT MAY BE COMORBID. IN SECONDARY CONDITIONS TREATMENT OF PRIMARY PROBLEM CAN IMPROVE SLEEP DISTURBANCE BUT IN SEVER INSOMNIA MAY NEED PHARMACOLOGICAL INTERVENTION AT LEAST FOR SHORT PERIOD OF TIME.PARENTS MUST BE INFORMED THAT THERE IS NOT FDA APPROVED DRUG FOR THIS PURPOSE AND MUST BE DISCUSS ABOUT COST BENEFIT OF THESE DRUGS. PHARMACOLOGICAL INTERVENTIONS MUST BE USED WHEN BEHAVIORAL INTERVENTIONS ARE INEFFECTIVE. IN SLEEP REGULATION NEUROTRANSMITTERS SUCH AS GABA, MELATONIN, HISTAMINE, NOREPINEPHRIN, ACETYLCHOLINE HAVE ROLE, AND THERE FOR DRUGS ARE USED FOR THIS PURPOSE AFFECT THEM. SEDATIVE EFFECT OF ANTIDEPRESSANTS LIKE TRAZODONE AND AMITRIPTYLINE IS RELATED TO ANTICHOLINERGIC MECHANISMS. THERE ARE VARIOUS FORMS ANTIHYSTAMINES AND ARE USED IN CHILDREN FOR INSOMNIA.ALSO ALPHA-ADRENERGIC AGONISTS SUCH AS CLONIDINE MAY BE USED FOR SEDATIVE EFFECT.
