Occlusion dysfunction (OD) is causally linked to an increased risk of Alzheimer’s disease (AD), while dentures restoration can mitigate this risk. Highlights: Periodontal disease (PD) and Alzheimer’s do not have a direct causal relationship (P = 0.395). Loose teeth significantly increase the risk of AD progression (P = 0.017, OR = 187.3567). Dentures restoration is …
Long-term practitioners of Orgasmic Meditation (OM) show distinct patterns of reduced brain metabolism compared to non-meditators, with significant differences in various brain regions involved in cognition, attention, and emotional regulation. Highlights: Reduced Metabolism: OM practitioners exhibit significantly lower metabolic activity in the frontal, temporal, and parietal lobes, as well as the anterior cingulate, insula, and …
