A study at Thomas Jefferson University Hospital found that mantra-based meditation can boost the mood of patients suffering from Alzheimer’s and other forms of memory impairment or loss. Participants in the study practiced Kirtan Kriya (KK) meditation on a daily basis for 8 weeks, reporting improvement in symptoms ranging from fatigue, anger, depression, and tension. Patients also experienced improvement in cognitive function, which researchers linked specifically to improvement in feelings of depression and confusion. The enhancement in cognitive function also led to improvements in memory for some participants. Researchers state that the study’s results are a promising first step in research examining the connection between meditation and brain function.
