GCA, global cortical atrophy; MTA, medial temporal lobe atrophy; ICV, intracranial volume; VCSF (total), relative total cerebrospinal fluid (CSF) volume (= total CSF volume expressed as a percentage of intracranial volume); sd, standard deviation
Intracranial volume was significantly different between males and females (p < 0.01). No significant differences in age, GCA and MTA score were found
