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.

The glymphatic system serves as the brain’s cleanup crew. It promotes the circulation of cerebrospinal fluid through the brain during deep sleep, flushing away amyloid and other proteins that can lead to neurological conditions such as Alzheimer’s, Parkinson’s disease, and Lewy body dementia.

Aging and a family history can increase the risk for a stroke, but women can lower it by managing factors that are under their control-such as diet, exercise, blood pressure, smoking, and diabetes.

When tremors progress from a mild nuisance to disrupting daily life, specific therapies may offer relief and help steady your movements.

Encephalitis, or brain inflammation, can cause symptoms ranging from mild, flu‑like illness to life‑threatening confusion and coma. Causes, recovery, and urgent treatments vary by virus.

Tingling, leg weakness, and voice changes can be alarming. Learn how doctors sort out these symptoms and when Parkinson's disease may be suspected.

A 2026 study suggested that helping care for grandchildren can offer cognitive benefits, helping older adults maintain stronger memory and language skills. Grandmothers who helped with childcare-related tasks also showed less overall cognitive decline over time than non-caregiving peers.

LATE dementia (which stands for limbic-predominant age-related TDP-43 encephalopathy) was formally recognized in 2019. LATE and Alzheimer's disease both involve progressive memory loss, but LATE usually advances more slowly than Alzheimer's.

Name slips and misplaced keys can feel unsettling in your 70s. Learn which memory changes are typical and when they might signal something more.
