Can ketogenic diet help Alzheimer's?

According to Andrew Huberman, there is mounting evidence that the ketogenic diet could potentially benefit those with Alzheimer's disease. Here are key points discussed on the Huberman Lab:

1. Anecdotal and Preliminary Evidence:

   • Small pilot trials and animal models suggest that the ketogenic diet can improve biomarkers of Alzheimer's and even enhance cognitive function in animal models 1.
   • There are clinical trials that show people in ketosis demonstrated improvements in daily living activities and quality of life, though cognitive improvements weren't always statistically significant 1 .

2. Mechanism:

   • Alzheimer's patients experience glucose hypometabolism, leading to insufficient energy for brain cells. Ketones provide an alternative energy source, which may help alleviate these deficits 2.

3. Challenges and Research:

   • There is a significant challenge in recruiting and maintaining participants for large studies, which has hindered more comprehensive research despite promising preliminary data 1 3.

   • The need for intensive support and education is emphasized since adherence to the diet can be complex 4 .

4. Practical Indications:

   • While not a cure, the ketogenic diet might help some Alzheimer's patients function better, and they may experience reduced symptoms upon reverting to higher-carb diets 5.
   • Improved blood flow to the brain and reduced inflammation when on a ketogenic diet could promote cognitive health 6.

In summary, while more extensive and controlled trials are needed, current theories and smaller studies indicate that the ketogenic diet could offer some therapeutic benefits for Alzheimer's patients by addressing brain energy metabolism issues and improving overall cognitive function.
