Different conditions cause brain atrophy, including cerebral palsy, dementia and infectious diseases. The CSF spaces comprise the sulci, fissures, basal cisterns and ventricles An appreciation of the normal appearances of the CSF spaces is required to allow assessment of brain volume The brain is surrounded by cerebrospinal fluid (CSF) within the sulci, fissures and basal cisterns. It is usually accompanied by enlarged cisterns (suprasellar and suprachiasmatic) and mildly enlarged ventricles (66%). Fluids Barriers CNS. Unfortunately, the cause of the majority of NPH cases is unknown, making it difficult to diagnose and understand. Occasionally, they can produce marked bone thickening with outward growth of the outer table of the skull [1, 4]. People lose some brain cells as they get older, and brain volume decreases as well, but healthcare providers use the term brain atrophy when a person has more brain changes than expected for age.
