Researchers aim to uncover causes of acquired hearing loss and find potential therapies

With a new five-year, $3.2 million grant from the National Institute on Deafness and Other Communications Disorders, researchers at Case Western Reserve University and Mass Eye and Ear will study what causes acquired hearing loss (AHL) and seek new ways to protect against it.

Baycrest study discovers role of thalamus in post-stroke recovery

A recent study by Baycrest reveals that an area of the brain distinct from the stroke lesion may play a significant role in causing the life-altering symptoms survivors are often left with, which can include severe challenges with speech, mobility and cognition.

Loss of empathy in frontotemporal dementia linked to brain activity changes

Patients with frontotemporal dementia often lack the ability to empathize. A study at Karolinska Institutet has now shown that these patients do not show the same brain activity as healthy individuals when they witness the pain of others, a finding that it is hoped will increase understanding of this specific dementia disease.

Lifestyle choices and cognitive health linked to future dementia risk

The risk of developing dementia later in life is strongly predicted by a person's cognitive ability, functional limitations and physical health as many as 20 years before onset of the illness, according to a new RAND report.

Skeletal muscle loss linked to increased risk of dementia

Skeletal muscle loss is a risk factor for developing dementia, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA).

Research sheds light on how mutated PSEN2 accelerates familial Alzheimer's disease progression

Alzheimer's disease is a debilitating condition that slowly robs people of their memory and cognitive abilities, affecting millions of people worldwide.

Ketone metabolism redefines protein quality control in aging brains

Ketone bodies, produced by the body to provide fuel during fasting, have roles in regulating cellular processes and aging mechanisms beyond energy production. Research at the Buck Institute shows that ketone bodies can best be understood as powerful signaling metabolites affecting brain function in aging and Alzheimer's disease.

Short sleep and high blood pressure may increase brain damage

People with high blood pressure who also lack sleep may be at increased risk of reduced cognitive performance and greater brain injury, Monash University research has found.

UK’s hearing loss organizations address misleading claims about dementia

The UK’s leading hearing loss organizations have joined forces to highlight misleading reports by some health professionals and the media that hearing loss causes dementia, and treating hearing loss will reduce our individual risk of dementia.

Understanding the role of sleep in dementia and associated illnesses

A new review was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 21, titled, "Sleep deprivation in dementia comorbidities: focus on cardiovascular disease, diabetes, anxiety/depression and thyroid disorders."

Study highlights the critical role of TLR7 in sex-biased Alzheimer’s-related demyelination

Inhibiting an immune signaling protein called TLR7 may help preserve the protective layer surrounding nerve fibers in the brain during both Alzheimer's disease and ordinary aging, suggests a study led by researchers at Weill Cornell Medicine.

Visceral fat found to contribute to Alzheimer's disease development

Researchers have linked a specific type of body fat to the abnormal proteins in the brain that are hallmarks of Alzheimer's disease up to 20 years before the earliest symptoms of dementia appear, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA).

Study links combined risk factors for aggressive behavior in men with CTE

People who have chronic traumatic encephalopathy (CTE) who have a family history of mental illness may have a higher risk of aggression in middle age, according to a study published in the November 27, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Research shows "Alzheimer's in a dish" model can accelerate drug discovery

A decade ago, researchers introduced a new model for studying Alzheimer's disease. Known as "Alzheimer's in a dish," the model uses cultures of mature brain cells suspended in a gel to recapitulate what takes place in the human brain over 10 to 13 years in just six weeks.
