Quote:Doctors use two tests to measure tau buildup in the brain.
PET scans are a type of brain imaging technique. Known as a tau-PET, this imaging test uses a special dye to help doctors visualize tau tangles in the brain.
Doctors can also measure tau protein levels by testing the cerebrospinal fluid surrounding the brain. They can extract this fluid via a lumbar puncture, also known as a spinal tap.
Researchers are also exploring the possibility of using a blood-based marker of tau buildup called p-tauTrusted Source. In other words, detecting tau may soon be possible using a simple blood test.

Quote:Here are the 10 foods the MIND diet encourages (11Trusted Source):

• Green, leafy vegetables: Aim for six or more servings per week. This includes kale, spinach, cooked greens, and salads.
  
• All other vegetables: Try to eat another vegetable in addition to the green leafy vegetables at least once per day. It’s best to choose non-starchy vegetables because they provide a lot of nutrients for a low number of calories.
  
• Berries: Eat berries at least twice per week. Berries such as strawberries, blueberries, raspberries, and blackberries all have antioxidant benefits (6Trusted Source, 7Trusted Source).
  
• Nuts: Try to get five or more servings of nuts each week. The creators of the MIND diet don’t specify what kind of nuts to consume, but it is probably best to vary the type of nuts you eat to obtain a variety of nutrients.
  
• Olive oil: Use olive oil as your main cooking oil. Check out this article for information about the safety of cooking with olive oil.
  
• Whole grains: Aim for at least three servings daily. Choose whole grains like oatmeal, quinoa, brown rice, whole wheat pasta, and 100% whole wheat bread.
  
• Fish: Eat fish at least once per week. It is best to choose fatty fish such as salmon, sardines, trout, tuna, and mackerel for their high amounts of omega-3 fatty acids.
  
• Beans: Include beans in at least four meals per week. This category includes all beans, lentils, and soybeans.
  
• Poultry: Try to eat chicken or turkey at least twice per week. Note that fried chicken is not encouraged on the MIND diet.
  
• Wine: Aim for no more than one glass daily. Both red and white wine may benefit your brain. While there has been much interest in the compound resveratrol, which is found in red wine, recent research has questioned whether it has clear benefits in humans.
  

Quote:A new study by Upstate Medical University researchers shows that recreational cannabis use may offer protection against cognitive decline.
The study, done by Master of Public Health (MPH) student Zhi Chen and Professor Roger Wong, Ph.D., MPH, MSW, analyzed a large data set from the CDC and found that compared to non-users, non-medical cannabis use, such as for recreational purposes, was significantly associated with 96 percent decreased odds of subjective cognitive decline (SCD).

SCD is an important outcome of interest as prior research shows individuals with SCD have a 2 times higher risk for dementia, which currently has no cure or definitive prevention approaches.

Data for this study was obtained from 4,744 U.S. adults aged 45 and older in the 2021 Behavioral Risk Factor Surveillance System (BRFSS). SCD was a self-reported increase in confusion or memory loss in the past year.

The study, which was published in Current Alzheimer Research was Chen’s final project in the Advanced Biostatistics course in the MPH program taught by Wong. 

“Based on our findings, we don’t see the CBD in medical cannabis being beneficial for cognitive health,” Wong said.
