Recent studies indicate that ketone bodies may play a significant role in improving cognitive function and clearing misfolded proteins linked to Alzheimer's disease (AD). Early human studies have shown promise in patients with mild to moderate AD, suggesting that a ketogenic diet, which induces the production of ketones, may be beneficial. The discussion also highlights the potential of exogenous ketone supplementation as an easier alternative to achieve cognitive benefits without the stringent dietary requirements of keto. There are insights shared on personal experiences with ketogenic diets improving focus and mental clarity, along with speculations on the relationship between sugar, fat intake, and cognitive health. Moreover, the alternative view that enhanced glucose metabolism could be associated with lower Alzheimer’s symptoms underscores the complexity of diet's impact on brain health. Highlighted is the enduring pursuit of effective Alzheimer’s treatments amid slow research progress, as well as the emotional toll of witnessing the effects of this disease firsthand.
