"Once people pass from mild cognitive impairment to Alzheimer's, then the rates of whole-brain atrophy are three times those seen in the healthy brain, and for the medial temporal lobe they are even higher," he said. The ventricles enlarge to handle the increased volume of CSF, thus compressing the brain from within and eventually damaging or destroying the brain tissue. Evaluation of subarachnoid space and subarachnoid cisterns in children and teenagers based on computed tomography studies. In an adult, the skull is rigid and cannot expand, so the pressure in the brain may increase profoundly. Cerebrospinal fluid space alterations in melancholic depression.
