Believe it or not, it's long  been understood that the brain has no lymphatic system!  It was just recently discovered that it does indeed HAVE lypmphatics!  And, why shouldn't it have lymphatics, it's the brain!!! While we sleep, the brain drains and detoxifies.  This has huge implications for any neurological disorders. They are finding that conditions such as Alzheimers, MS, etc are a result of an accumulation of toxins in the brain.  The brain's lymphatic pathways run along the venous sinus drainage in the head.  I've had many people report they feel much more clarity in their thinking after enhancing the venous and lymphatic drainage of the brain via Biodynamic Craniosacral.
