How to prevent dementia?

Sources:

To prevent dementia, the following strategies have been discussed on the Huberman Lab podcast:

  1. Sleep and Exercise: Quality sleep and regular cardiovascular exercise are foundation elements for mental and physical health, which can impact brain function 1. Lack of sleep is linked to dementia and exacerbating pre-existing dementias 1. Consistent cardiovascular exercise is crucial for heart health, which is directly related to brain health 1.

  2. Cognitive Activity: It's also important to engage in cognitive activities regularly. However, there isn't a structured guideline on cognitive "exercise," but the concept is that just as the body needs physical activity, the brain requires stimulation through learning and other cognitive tasks 2.

  3. Disease Modulation: Alzheimer's was discussed as both the most prevalent form of dementia and neurodegenerative disease, and there is the possibility of altering the slope of cognitive decline to prevent diseases like Alzheimer's 3.

    Brain-Boosting Foods

    Andrew discusses the impact of nutrition on brain health and function. He emphasizes the importance of getting quality sleep and exercise for overall health, but also shares specific foods that have been shown to enhance brain function.

  4. Estrogen Optimization: For both men and women, optimizing estrogen levels is important for cognition and vascular function. Estrogen boosts dopamine activity, which is vital for brain function 4.

  5. Neurogenesis from Exercise: Cardiovascular exercise can increase the creation of new neurons in the dentate gyrus, which is involved in memory formation. Aiming for 180-200 minutes of zone two cardiovascular exercise per week is suggested to impact neurogenesis and enhance learning and memory 5.

  6. Isoform Consideration: Understanding genetic factors like the Apob gene isoforms E2, E3, and E4 can provide insights into varying levels of risk for developing Alzheimer's and offer potential protective measures 6.

It should be noted that these strategies are parts of ongoing research and discussions in the field and could be supplemented by further studies. Always consult with healthcare professionals for personalized health advice.
