People who aggressively lower their high blood pressure not only help their heart health, but also may protect their brains from cognitive decline in the process, according to a 2025 study.

Communicating with someone with dementia can be tricky, since their ability to understand others and express themselves fluctuates and declines. Certain communication strategies can help smooth interactions between caregivers and dementia patients. They include being an active listener, avoiding confrontation, agreeing with the patient's reality, removing distractions, using shorter sentences and smaller words, asking yes-or-no questions, using written lists and schedules, and incorporating touch.

Dementia poses many challenges, both for people struggling with it and for those close to them. Understanding common behaviors and learning to handle situations that arise can help families and caregivers.

More than 30% of adults over 70 have amyloid or tau (proteins implicated in the development of Alzheimer's disease) in their brains yet have no apparent cognitive problems. This may indicate greater cognitive reserve, the brain's ability to compensate for damage.

A long-running study found that closely following the MIND Diet was linked with significantly slower age-related brain changes, including 20% less shrinkage in grey matter-equivalent to slowing brain aging by 2.5 years. However, it's not known if these changes translate to better brain function.

Neurogenesis is the birth of new nerve cells, called neurons, in the brain. The ability to grow new neurons appears more prominent in super-agers, people 80 and older whose thinking and memory skills are as sharp as adults who are decades younger.
