The lymphatic clearance pathways of the brain are different compared to the other
organs of the body and have been the subject of heated debates. Drainage of brain
extracellular fluids, particularly interstitial fluid (ISF) and cerebrospinal
fluid (CSF), is not only important for volume regulation, but also for removal of
waste products such as amyloid beta (A?). CSF plays a special role in clinical
medicine, as it is available for analysis of biomarkers for Alzheimer's disease.
Despite the lack of a complete anatomical and physiological picture of the
communications between the subarachnoid space (SAS) and the brain parenchyma, it
is often assumed that A? is cleared from the cerebral ISF into the CSF. Recent
work suggests that clearance of the brain mainly occurs during sleep, with a
specific role for peri- and para-vascular spaces as drainage pathways from the
brain parenchyma. However, the direction of flow, the anatomical structures
involved and the driving forces remain elusive, with partially conflicting data
in literature. The presence of A? in the glia limitans in Alzheimer's disease
suggests a direct communication of ISF with CSF. Nonetheless, there is also the
well-described pathology of cerebral amyloid angiopathy associated with the
failure of perivascular drainage of A?. Herein, we review the role of the
vasculature and the impact of vascular pathology on the peri- and para-vascular
clearance pathways of the brain. The different views on the possible routes for
ISF drainage of the brain are discussed in the context of pathological
significance.
