The page will highlight some of the recent research on health and well-being as it pertains to aging. I try to access the primary source, or else a summary of the primary sources.
One of the biggest fears people have is loss of cognitive functioning. Here is a Ted Talk that discusses the factors that increase or decrease neuro-regeneration. The factors that increase neurogenesis are learning new things, sex, running, calorie restriction, intermittent fasting, dark chocolate, blueberries and food that requires chewing. Factors that decrease neurogenesis are stress, sleep loss, getting older and a diet high in saturated fat. Diet affects mood in the same direction as neurogenesis. Meditation was not included in the review. Cameron Magg at the Vancouver Coastal Research Institue summarizes some of the research on brain regeneration regarding exercise and stroke.
Diets/Food/Supplements and cognitive functioning
The diet and food supplement industry is a big business. I will attempt to link to some studies that help to separate out the hope and the hype. One study recently published was on fasting. The important finding was there is some cellular regeneration with re-feeding after fasting. Most of the studies are tracking cardiovascular, cancer and diabetes and are in animals or small short-term studies of humans. Compliance and drop outs are a problem with some studies. This summary of the research suggests fasting might be a benefit to a small subgroup of people, perhaps those with diabetes. More research is underway.
Meditation/Mindfulness and cognitive functioning
The topic of meditation and mindfulness is experiencing an uptake in research. This article covers a lot of diverse information on meditation and brain functioning.

Hearing testing and hearing aids.
A recent review in the Lancet of factors affecting the development of dementia included hearing loss in mid life as a contributing factor to dementia. The study estimated a 9% reduction in the rates of dementia if hearing loss was prevented. However there was no evidence that hearing aids mitigate the risk of dementia. If one was to hope that hearing aids might help to prevent dementia, there are hearing devices that are cheaper than hearing aids that provide similar amplification. In a comparison between hearing aids and hearing devices, the mean accuracy without an aid was 76.5, 88.4 with a hearing aid and from 87-65 with the Personal Sound Amplification Devices.
Here are links to the top three devices:
The Sound World is the most accurate of the aids tested in the JAMA article above. Accuracy was 87.4. $ 349 US each. The second most accurate was the Sound Hawk. This is a link to an extensive review of this product by a third party. The Sound Hawk site as down as this time but the product is available on Amazon with reviews. This is the second most accurate of the devices. Part 3 is a response to the review by SoundHawk which is not currently available on Amazon. Accuracy was 86.7. The third most accurate was the Etyomtic Bean available on Amazon (84.1). $489.15 CDN each.
You might also take a look at LifeEars who claim to have low cost ($ 600 US pair ) hearing amplifiers.
My local contacts tell me that Costco has the best prices for hearing aids.
Estrogen Cream- Premarin
I have had a recent experience using this and was very unhappy with the adverse effects. I have reported the adverse effects to the Health Canada website where you can do a search for any product and see who has reported adverse reactions or you can report yourself.
