“…Data sources/measurement of variables: the study involved the collection of brain CT-scan images, which were already scanned using 6, 16 and 128 slices using Siemens Somatom Emotion, Sensation and Definition machines respectively, with a slice thickness of 5mm and an increment of 2mm. From Figure 1 , a computer-assisted system was used to measure the brain volume of all the images using a DBF formula designed to measure the dimensions of the brain relative to the skull and ventricles [ 13 ]. This study considered cut-off for a DBF value of 0.75 to describe the presence of brain atrophy.…”

“…Thus, a value <0.75 indicated the presence of atrophy, and a value >0.75 indicated normal brain volume. Additionally, to grade the severity of brain atrophy, this study considered the range and grade of brain atrophy as follows: 0.15 - 0.30 (very severe), 0.31 - 0.45 (severe), 0.46 - 0.60 (moderate), 0.61 - 0.75 (mild), and >0.75 (normal brain volume) [ 13 ].…”

“…A radiologist examined the Brain CT-scan images, which evaluated sulcal width, lateral ventricular body width and the Evans index using the three familiar radiological linear procedures. Diagonal multi-linear (DBF) approach was calculated to identify the presence or absence of brain atrophy for those who qualified for the use of this technique [22].…”
