Deans' stroke musings: Keto Diet Delays Alzheimer’s Memory Loss

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Keto Diet Delays Alzheimer’s Memory Loss

Do you have a competent? doctor and hospital enough so they'll ensure human testing gets done?

Of course your competent? doctor and hospital already know about beta-hydroxybutyrate because of this earlier research.

Keto Diet Delays Alzheimer’s Memory Loss

Summary: A ketogenic diet significantly postpones the onset of Alzheimer’s-related memory decline in mice, a phase akin to human mild cognitive impairment preceding Alzheimer’s disease. Key findings highlight the molecule beta-hydroxybutyrate (BHB) as instrumental in this protective effect, showing a nearly seven-fold increase in mice on the diet and improving synaptic function critical for memory.

While the study indicates that the diet, particularly BHB, doesn’t eliminate Alzheimer’s, it suggests potential for delaying its early stages. Additionally, the research noted more pronounced benefits in female mice, pointing to intriguing implications for human health, especially among women at higher risk for Alzheimer’s.

Key Facts:

Ketogenic Diet’s Protective Role: The ketogenic diet boosts levels of BHB in the body, which is linked to delaying the early stages of Alzheimer’s-related memory loss in mice.
Gender-Specific Benefits: The ketogenic diet was found to be more beneficial for female mice, indicating a potential for greater impact on women, particularly those with the ApoE4 gene variant linked to higher Alzheimer’s risk.
Future Research Directions: The findings open new avenues for research into healthy aging and Alzheimer’s prevention, with an emphasis on further exploring the effects of BHB supplementation and the ketogenic diet’s neuroprotective mechanisms.

A new study from researchers at the University of California, Davis, shows a ketogenic diet significantly delays the early stages of Alzheimer’s-related memory loss in mice. This early memory loss is comparable to mild cognitive impairment in humans that precedes full-blown Alzheimer’s disease.

The study was published in the Nature Group journal Communications Biology.

The ketogenic diet is a low-carbohydrate, high fat and moderate protein diet, which shifts the body’s metabolism from using glucose as the main fuel source to burning fat and producing ketones for energy. UC Davis researchers previously found that mice lived 13% longer on ketogenic diets.

Slowing Alzheimer’s

The new study, which follows up on that research, found that the molecule beta-hydroxybutyrate, or BHB, plays a pivotal role in preventing early memory decline. It increases almost seven-fold on the ketogenic diet.

“The data support the idea that the ketogenic diet in general, and BHB specifically, delays mild cognitive impairment and it may delay full blown Alzheimer’s disease,” said co-corresponding author Gino Cortopassi, a biochemist and pharmacologist with the UC Davis School of Veterinary Medicine.

“The data clearly don’t support the idea that this is eliminating Alzheimer’s disease entirely.”

Scientists gave mice enough BHB to simulate the benefits of being on the keto diet for seven months.

“We observed amazing abilities of BHB to improve the function of synapses, small structures that connect all nerve cells in the brain. When nerve cells are better connected, the memory problems in mild cognitive impairment are improved,” said co-corresponding author Izumi Maezawa, professor of pathology in the UC Davis School of Medicine.

Cortopassi noted that BHB is also available as a supplement for humans. He said a BHB supplement could likely support memory in mice, but that hasn’t yet been shown.

Other cognitive improvements

Researchers found that the ketogenic diet mice exhibited significant increases in the biochemical pathways related to memory formation. The keto diet also seemed to benefit females more than males and resulted in a higher levels of BHB in females.

“If these results translated to humans, that could be interesting since females, especially those bearing the ApoE4 gene variant, are at significantly higher risk for Alzheimer’s,” Cortopassi said.

The research team is optimistic about the potential impact on healthy aging and plans to delve further into the subject with future studies.
