Patients with severe cortical CSF changes showed a 7.8-fold excess risk of depression relapse/recurrence compared with patients with no cortical CSF space alteration. Depending on how old you are- as we age the brain shrinks and you see more fluid around the brain and the ventricles- the fluid spaces get a bit larger.
