Herbal boost? ashwagandha may improve brain function in schizophrenia

This study looked at whether adding ashwagandha, an herbal supplement, to standard schizophrenia medication (risperidone) could improve thinking and memory. 80 men with schizophrenia took either risperidone alone or risperidone plus ashwagandha for 8 weeks. Researchers measured changes in a brain chemical (BDNF) and cognitive test scores to see if the combination worked better.
