Risk Factors

New study shows potential link between bad quality sleep and Alzheimer’s in Hispanics

Hispanics who have trouble sleeping may be at a higher risk of Alzheimer’s disease or other dementias, according to a new study.

Blood test method may predict amyloid deposits in brain, potentially indicating Alzheimer's disease

A number of research projects are underway to develop a sensitive blood test that could help screen people for Alzheimer’s disease in a less invasive and costly way than current imaging and biomarker tests. NIA-supported researchers at Washington University in St. Louis reported an advance Aug. 1 in Neurology for their method of detecting amyloid protein in blood. The researchers are validating the method by showing an association between blood levels of amyloid and results from conventional biomarker tests for Alzheimer’s.

How Deep Sleep May Help The Brain Clear Alzheimer's Toxins

The brain waves generated during deep sleep appear to trigger a cleaning system in the brain that protects it against Alzheimer's and other neurodegenerative diseases.

Why Didn’t She Get Alzheimer’s? The Answer Could Hold a Key to Fighting the Disease

Researchers have found a woman with a rare genetic mutation that has protected her from dementia even though her brain has developed major neurological features of the disease.

Cognitive decline and social isolation common reasons for elderly financial abuse

One in 10 older adults are victims of abuse, with many being the victims of financial scams. Researchers are now studying why older adults are more susceptible and believe very early stages of Alzheimer’s and mild cognitive impairment could play a role.

ASU researcher studies menopause and memory loss

Women experience many symptoms during menopause which can include difficulty concentrating and memory loss.  Arizona State University researcher Dr. Bimonte-Nelson is studying the link between memory and thinking problems and the onset of menopause.

Migraines a risk factor for developing dementia and Alzheimer's, study suggests

Migraines could raise the risk of developing dementia, including Alzheimer's disease, according to researchers. The study published in the International Journal of Geriatric Psychiatry involved 679 people aged 65 or over in Canada, who didn't have dementia.

New Study Explores the Relationship Between Mental Cognition and Exercise

Exercise has long been known to provide a wealth of health benefits, both physical and mental. But a new study suggests that exercise can boost mental cognition immediately following the session.

Markers of abnormal liver function linked to Alzheimer's disease

Abnormal liver enzyme levels detected by commonly used blood tests may be linked to Alzheimer’s disease diagnosis and multiple biomarkers of the disease, according to a recent study. The findings were published July 31 in JAMA Network Open. Led by NIA-supported scientific teams at Duke University and Indiana University, the research was based on the rationale that abnormal changes in liver enzymes are associated with heart disease and metabolic disorders like diabetes, which are known risk factors for Alzheimer’s.

High Blood Pressure in Your 30s May Affect Your Brain, Increase Dementia Risk

High blood pressure is linked to a lot of common health problems, most notably stroke and heart disease. Scientists have also established a link between high blood pressure and increased dementia risk. But a new study finds that an uptick in blood pressure — even as early as your 30s — could lead to a higher dementia risk later on.
