Servette Vs St Gallen Head To Head, who studied the distribution of subarachnoid spaces (SS) enlargement contested the theory of impaired CSF absorption because such mechanism should also determine a ventricular enlargement and an uniform dilatation of extra-axial cerebrospinal spaces, whereas dilatation of subarachnoid spaces is mainly frontal in scaphocephaly. Brain atrophy (cerebral atrophy) is a loss of neurons and connections between neurons. "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. Many conditions cause brain atrophy, so the severity of damage can vary. prominent extra axial csf spaces in adults.
