[Therapeutic indications of S-adenosyl methionine in neuropsychiatry].

Studies conducted by Italian and Anglo-saxon authors underline the thymoanaleptic properties of a transmethylant biological substance, the S-adenosyl methionine (SAMe). The authors discuss a review of literature concerning the use of SAMe in neuro-psychiatry, particularly in the treatment of affective disorders. The many physiopathological implications are subtended by the biological inter-relations of SAMe with other biological substances. Some hypotheses are proposed on the role played by phospholipid methylation, the folate metabolism and the purinergic transmission in mental diseases.
