The multidrug treatment therapy with the statin cocktail (simvastatin, L-Arginine, and tetrahydrobiopterin) that targets augmentation of the endothelial nitric oxide synthase pathway may improve cerebral blood flow and cognitive function in patients with Alzheimer’s Disease.
Time-series cerebral blood flow rCBF images are shown for the right hippocampus (A) and right middle temporal lobe (B) of Patient 1 from Group 1. With the progression of time, the rCBF values show an increased signal for structures in the limbic system and the cortical area for all patients in Group 1.
T-value maps generated using the SPM12 software results are shown for the MCA region of the brain comparing all the patient groups at each time-point. A single patient rCBF map is shown with intensity overlays, which show the regional differences for each group comparison. Higher T-values indicate greater differences compared to the lower T-values. Groups 1 and 3 show the greatest difference between each other compared to the other group comparisons particularly at the 1-month and 2-month time-points. By 4 months, groups 1 and 3 showed more differences compared to the others.
