S-Adenosylmethionine (SAMe) for Neuropsychiatric Disorders: A Clinician-Oriented Review of Research
Abstract
Objective: A systematic review on S-adenosylmethionine (SAMe) for treatment of neuropsychiatric conditions and comorbid medical conditions.
Data sources: Searches were conducted in PubMed, EMBASE, PsycINFO, Cochrane Library, CINAHL, and Google Scholar databases between July 15, 2015, and September 28, 2016, by combining search terms for SAMe (s-adenosyl methionine or s-adenosyl-l-methionine) with terms for relevant disease states (major depressive disorder, MDD, depression, perinatal depression, human immunodeficiency virus, HIV, Parkinson's, Alzheimer's, dementia, anxiety, schizophrenia, psychotic, 22q11.2, substance abuse, fibromyalgia, osteoarthritis, hepatitis, or cirrhosis). Additional studies were identified from prior literature. Ongoing clinical trials were identified through clinical trial registries.
Study selection: Of the 174 records retrieved, 21 were excluded, as they were not original investigations. An additional 21 records were excluded for falling outside the scope of this review. Of the 132 studies included in this review, 115 were clinical trials and 17 were preclinical studies.
Data extraction: A wide range of studies was included in this review to capture information that would be of interest to psychiatrists in clinical practice.
Results: This review of SAMe in the treatment of major depressive disorder found promising but limited evidence of efficacy and safety to support its use as a monotherapy and as an augmentation for other antidepressants.…
