It's big leap to assume that massage of peripheral lymph vessels (e.g. arms and legs) affect lymph draining in the brain. I'm always a bit perplexed when people's first reaction to new hard science is to assume that it supports more or less pseudoscience. Especially in a forum where hard evidence is the norm and encouraged. Just because some research shares a noun with pseudoscience doesn't mean that X supports Y.
