Compared with eating carbohydrates, eating protein—particularly protein from plants— was associated with lower odds of later developing cognitive declines, according to a Harvard study in the January 2022 issue of The American Journal of Clinical Nutrition.

Psychedelic drugs such as psilocybin (found in "magic mushrooms") and 5-MeO-DMT (a compound derived from toad venom) are being tested for treating cases of depression that don't respond to standard treatments. New depression approaches are needed since current treatments don't work in nearly half of patients. Hallucinogenics may change longstanding thought patterns or promote new connections in brain neurons. Benefits of psilocybin on mood appear to be long-lasting. FDA approval for psilocybin will likely take several more years.

A new study suggests a high-fiber diet may protect against dementia. In a group of about 3,700 older adults, those who consumed the most fiber (about 20 grams daily) had the lowest rates of dementia, and those who ate the least fiber (8 grams daily) had the highest rates.

People who struggle to remember names, details, or words during conversation are dealing with a phenomenon called "blocking," which is related to diminished memory recall. Addressing issues like stress, depression, an unhealthy diet, insomnia, lack of exercise, and prolonged isolation can improve recall. Otherwise, when blocking situations arise, people can try to incorporate cueing, a method that uses "hints" to help the brain better retrieve information.

Cognitive distortions are internal mental filters or biases that fuel anxiety and make us feel bad about ourselves. These filters can cause us to devolve into counterproductive brooding that can worsen depression or anxiety and stall positive lifestyle changes. So how can you recognize and overcome these distortions?

LATE is a brain disorder that causes dementia in older individuals. In fact it is the third most common cause of dementia, but it affects many of the same brain regions as Alzheimer's disease so it presents with similar symptoms, and it's only with the advent of special diagnostic tests that clinicians have realized how common it is.

We all have habits we'd like to break, but the brain doesn't make changes easily. Breaking an unhealthy habit can be done; to do so, it helps to understand what's happening in the brain, know why you want to change, and accept that there will be setbacks along the way.

A 2020 study found that people defined as lonely had a higher risk of dementia than those who were not considered lonely. Loneliness also was associated with smaller brain sizes and poorer executive function (the ability to plan, focus attention, and remember instructions).
