Antidepressants have the potential to improve memory and thinking skills, a new study suggests. Some patients experienced a boost on brain tests after taking the SSRI antidepressant escitalopram (Lexapro), researchers report. The drug appeared to affect a serotonin receptor in the brain called the 5HT4 receptor, according to results published recently in the journal Biological Psychiatry. Serotonin is described as a “feel good” hormone, researchers said in background notes. Higher levels of serotonin in the brain contribute to a sense of well-being and have been shown to ease clinical depression. “It seems that the SSRI medication contributes to an improvement on cognitive function, at the same time as helping improve mood,” said lead investigator Vibeke Dam, a senior researcher in neurology and neurobiology with Copenhagen University Hospital in Denmark. “Our work ties the improvement in cognitive function to the specific 5HT4 receptor and suggest that direct serotonin 4 receptor stimulation may be an important pro-cognitive target to consider in optimizing outcomes of antidepressant treatment,” Dam added in a journal news release. “It also reinforces the idea that serotonin is crucial to mood improvement.” For the study, researchers scanned the brains of 90 depressed patients to measure 5HT4 receptor function in their brains. The patients also were tested for mood problems and cognitive abilities. Then the patients were given daily escitalopram (Lexapro) for eight weeks. At… read on > read on >
