Note: In exponent are signaled the number of missing values for each test and group (a: 1 missing value; b: 2 missing values; c: 3 missing values). Among patients suffering for tumors, 18 presented with a glial tumor, 6 with a meningioma, and 5 with another or unknown etiology. Vascular patients had either ischemia (n = 3) or haemorrhage (n = 9) due to the rupture of a vascular malformation. Time interval corresponds to the period of time separating the neuropsychological evaluation and the brain imaging.
