Dementia

Mild cognitive impairment – an early stage of dementia – is widely underdiagnosed in people 65 and older.

A decade-long U.S. study found a slight increase in dementia risk among people exposed to PM2.5 air pollution, particularly from agriculture and wildfires. The research emphasizes the need for targeted air quality interventions to reduce dementia's burden.

A study revealed that a blood test, identifying 11 proteins, can predict dementia with 90% accuracy up to 15 years before diagnosis, offering a non-invasive, cost-effective alternative for early detection and intervention, enhancing patient care and treatment opportunities.

A new study in Neurology shows erectile dysfunction medications may reduce Alzheimer's risk by 18%. Exploring drug repurposing, researchers found men prescribed these drugs had a lower incidence of Alzheimer's, offering a promising avenue for prevention and highlighting the need...

A recent study in the Neurobiology of Aging reveals that individuals with high levels of openness, a trait marked by curiosity and a broad interest spectrum, have a stronger cognitive reserve, potentially shielding against the cognitive decline seen in conditions...

New research has linked a healthier diet to a reduced risk of dementia and a deceleration in the pace of aging. This study, published in the Annals of Neurology, provides new insights into how diet can influence the complex mechanisms...

A study of over 1,000 adults over 40 found that playing musical instruments is linked with improved working memory and executive function, suggesting that musical engagement may enhance cognitive reserve and potentially reduce the risk of cognitive impairment in older...

A study from Bengaluru, India, reveals bilingualism could protect older adults from dementia and mild cognitive impairment, emphasizing the cognitive benefits of speaking multiple languages regardless of educational background.

New research suggests living in socioeconomically disadvantaged neighborhoods might impact cognitive abilities in older individuals, independently of brain pathologies. Higher education appears to mitigate these effects, suggesting cognitive reserve plays a key role in brain health.

In a groundbreaking 12-week study, daily fiber supplements improved brain function in twins over 65, hinting at a link between gut microbes and cognitive health. Prebiotic fibers like inulin and FOS altered gut microbiome, boosting beneficial bacteria.

A study by Baycrest and the University of Toronto found speech speed, not word-finding difficulty, is a key indicator of cognitive health in aging. Slower speech may signal brain changes, challenging assumptions that struggling to find words is a major...

MIT researchers have found that 40Hz sensory gamma rhythm stimulation can significantly slow Alzheimer's progression by enhancing the brain's glymphatic system to clear amyloid proteins. This breakthrough offers new hope for treating Alzheimer's through non-invasive light and sound therapy.

UCLA Health discovers Kundalini Yoga enhances memory, reverses aging biomarkers, and supports brain health in women at Alzheimer's risk, surpassing standard memory exercises. A holistic approach may offer comprehensive cognitive benefits, highlighting yoga's potential in Alzheimer’s prevention.

Frontotemporal dementia (FTD) affects behavior and language, with genetics playing a key role. Studies on genes and proteins linked to FTD and ALS offer hope for treatments, exploring brain circuitry and potential for reversing symptoms.

Scientists have developed a machine learning model that predicts Alzheimer's onset up to seven years early, identifying high cholesterol and osteoporosis as key predictors, especially in women. Published in Nature Aging, this study marks a significant step toward early diagnosis...
