Wasn't the lymphatic system of the brain only just discovered in the last decade?

I have a condition called venous sinus stenosis (narrowing of the major cerebral veins, mine was treated with venous sinus stenting) which is linked heavily to cerebrospinal fluid and intrcranial hypertension. The pathophysiology of onset in these cerebral venous congestion disorders remains unclear but there has been some evidence to suggest the glymphatic system may be involved. Really fascinating stuff!
