Increased extra-axial CSF volume is a reliable brain anomaly that has now been found in three independent cohorts, comprising both high-risk and normal-risk children with autism spectrum disorder. Compounding this difficulty is the fact that some of the symptoms of NPH are similar to the effects of the aging process, as well as diseases such as Alzheimer's and Parkinson's. Often discovered incidentally or when patients undergo neuroimaging in the workup of macrocephaly. Signs of a shunt malfunction include headaches, vision problems, irritability, fatigue, personality change, loss of coordination, difficulty in waking up or staying awake, a return of walking difficulties, mild dementia or incontinence. CSF is of lower density than the grey or white matter of the brain, and therefore appears darker on CT images.
