Research is being conducted on the glymphatic system in adults with type 2 diabetes mellitus, with studies using various methods such as diffusion tensor imaging analysis and multimodal neuroimaging. The studies appear to be investigating the relationship between glymphatic system impairment and various factors, including cognitive impairment, sleep, and exercise therapy. The research also seems to be exploring the broader implications of glymphatic system dysfunction, including its potential connections to psychiatric disorders and other health conditions.
