Dementia

Overview

Dementia is not part of healthy aging. It's a severe cognitive impairment that compromises one's ability to perform daily activities and function independently. No one test definitively diagnoses dementia—instead, a test series, brain scans, and an expert's consideration of the overall pattern of symptoms lead to a formal diagnosis.

Hours of research by our editors, distilled into minutes of clarity.

  • How Alzheimer's disease affected one family as symptoms progressed

    News program 60 Minutes interviewed a couple navigating aging and Alzheimer's over a 10-year period to illustrate the effects of the disease on their lives.

  • Dementia caregiver training programs exist—but they aren't common

    Comprehensive dementia care programs go beyond offering support to caregivers. They train people on how to modify their homes, communicate with their loved ones with dementia, and cope with the stress of caregiving, among other skills. Yet despite evidence showing their effectiveness and the economic benefit of avoiding unnecessary emergency room visits, these programs are often poorly funded and difficult to find.

  • Dementia describes progressive memory issues that impact daily activities

    Although Alzheimer's disease is sometimes thought of synonymously with dementia, there are multiple types of dementia, which manifest in memory loss and other symptoms that make it challenging to perform daily tasks. These types include Lewy Body dementia, vascular dementia, and frontotemporal dementia. Parkinson's disease is not a form of dementia, but this movement disorder can sometimes develop into issues with memory and a formal diagnosis of dementia.

  • Learn the differences between mild cognitive impairment and age-associated memory loss

    Mild cognitive impairment is a condition in which people experience more thinking and memory problems than expected for their age. It's often associated with depression and anxiety. Daily routines, writing things down, and healthy lifestyle choices can help cope with the condition, but there's no cure. The condition elevates the risk of developing dementia and Alzheimer's.

  • Why vascular dementia develops

    This type of dementia, the second most common form after Alzheimer's, develops due to microscopic bleeds and blood vessel blockages in the brain. The condition isn't curable but medications to help with blood clotting and high blood pressure are part of a suite of interventions designed to minimize damage to the brain.

  • Brain training game creates long-lasting changes in the brain that may help protect against dementia

    Findings published in 2026 that tracked more than 2,000 older adults, examining dementia onset and completion of cognitive speed training activities, provide some of the strongest evidence yet that cognitive training games can help protect against dementia. Participants who underwent speed training and received booster sessions had a 25% reduction in the risk of dementia diagnosis compared with the control group.

  • Repeated head injuries can lead to CTE and early dementia

    Chronic traumatic encephalopathy is a progressive neurodegenerative disease caused by repeated trauma to the head. The condition has become a particular concern in sports like football and soccer, from youth to professional leagues, where repeated low-level concussive events are likely.
