A New research links antidepressants to the REM Sleep Behavior Disorder (RBD). The study conducted by Mayo clinic points that using antidepressants causes the onset of this disorder at a younger age.
RBD is a sleep disorder where patients act out their dreams, which are often unpleasant and violent, according to Maja Tippmann-Peikert, M.D., sleep medicine specialist, neurologist and study investigator. This acting out results from a loss of normal muscle paralysis in REM (rapid eye movement) sleep, the dream stage of sleep, which normally prevents enacting one's dreams. RBD patients generally act out their dreams in a defensive posture, as if fending off an attacker, says R. Robert Auger, M.D., Mayo Clinic sleep medicine specialist, psychiatrist and primary investigator. The disorder is often recognized by a bed partner.
Although previously published case reports and a more recently published study have suggested the association between antidepressants and RBD, this study represents the first systematic demonstration of the relationship. Findings will be presented June 19 at the Associated Professional Sleep Societies' SLEEP 2006 meeting in Salt Lake City.
