In the first part of this series, we discussed the role of the craniosacral primary respiratory rhythm in cranial hydrodynamics. In the second article, we discussed the role of the accessory drainage system (vertebral venous plexus,VVP) in humans and cranial hydrodynamics during upright posture. In the third article, we discussed the role of the craniocervicxal spine as the critical link between the cranial dural sinuses and the accessory drainage system, and how craniocervical syndromes may cause blockage or hydrodynamic failure of the cranial dural sinuses and subsequent chronic normal pressure hydrocephalus (NPH). In this last article, we will discuss a possible link between chronic NPH and Alzheimer’s (AD), Parkinson’s (PD) and other diseases.
