Alzheimer's Disease News and Research

RSS

Alzheimer's disease (AD) is an irreversible, progressive brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living. In most people with AD, symptoms first appear after age 60. AD is the most common cause of dementia among older people, but it is not a normal part of aging. Dementia refers to a decline in cognitive function that interferes with daily life and activities. AD starts in a region of the brain that affects recent memory, then gradually spreads to other parts of the brain. Although treatment can slow the progression of AD and help manage its symptoms in some people, currently there is no cure for this devastating disease.

Nasal spray may offer new hope for traumatic brain injury patients

A new study led by researchers at Mass General Brigham suggests a nasal spray developed to target neuroinflammation could one day be an effective treatment for traumatic brain injury (TBI).

New study identifies effective blood tests for ALS diagnosis and monitoring

ALS, or amyotrophic lateral sclerosis, can sometimes be difficult to diagnose or to predict how quickly the disease is likely to progress. A new study helps determine which blood tests are best at identifying and monitoring ALS.

Pilot study explores potential of senolytics in Alzheimer's prevention

A new pilot study known as STAMINA (Senolytics To Alleviate Mobility Issues and Neurological Impairments in Aging), that focused on the effects of senolytic medications, Dasatinib and Quercetin (DQ), which remove old (senescent) cells from the body, suggests that intermittent treatment may hold promise for improving cognitive function in older adults at risk of Alzheimer's disease.

New study uncovers how the brain creates spatial maps

The brain creates internal 'maps' to help us navigate and learn from our surroundings, but how these maps form remains a challenge to understand.

Retinal changes may serve as early indicator for Alzheimer's disease

A team of scientists at the Indiana University School of Medicine has identified that an eye condition affecting the retina, the light-sensing tissue in the back of the eye, may serve as an early indicator for Alzheimer's disease.

Mass General Brigham study uncovers 16 novel Alzheimer's risk genes

Investigators from Mass General Brigham have conducted a multi-ancestry, whole genome sequencing association study of Alzheimer's disease and found evidence for 16 new susceptibility genes, expanding the study of Alzheimer's disease in underrepresented groups.

New AI tool measures brain aging speed and predicts cognitive health

A new artificial intelligence model measures how fast a patient's brain is aging and could be a powerful new tool for understanding, preventing and treating cognitive decline and dementia, according to USC researchers.

Small amounts of exercise linked to lower dementia risk in older adults

A little movement could help prevent dementia, even for frail older adults, suggests a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health.

Blood test for Alzheimer’s could replace costly and invasive spinal taps

Researchers indicate that the Lumipulse p-tau217 assay may reduce over 50% of lumbar punctures performed for diagnosing Alzheimer's disease.

Infant exposure to herpes virus may cause memory problems later in life

Very early exposure to even a very small dose of herpes simplex virus (HSV) in infant mice can lead to cognitive decline later in life, according to findings from a new Dartmouth-led study, in collaboration with Harvard Medical School and published in the journal PLoS Pathogens.

Direct connection found between memory and sensory processing centers in brain

A newly identified part of a brain circuit mixes sensory information, memories, and emotions to tell whether things are familiar or new—and important or just "background noise."

New review sheds light on links between Alzheimer's and metabolic syndrome

Alzheimer's disease (AD), the most common form of dementia, continues to remain one of modern medicine's greatest challenges.

New review maps the impact of reproductive hormones on neurological health

A comprehensive review published today in Brain Medicine by leading neuroendocrinologist Professor Hyman M. Schipper from McGill University's Department of Neurology and Neurosurgery maps out the extensive influence of reproductive hormones on neurological health and disease.

Researchers discover direct feedback loop in brain circuit connecting memories and emotions

A newly identified part of a brain circuit mixes sensory information, memories, and emotions to tell whether things are familiar or new, and important or just "background noise."

Lecanemab and donanemab slow Alzheimer’s decline, but is the benefit worth the cost?

Study finds that disease-modifying therapies for Alzheimer’s, lecanemab and donanemab, can extend independence in daily activities by up to 13 months, though their clinical relevance remains debated.

Breakthrough technology enables mRNA delivery across the blood-brain barrier

Scientists at the Icahn School of Medicine at Mount Sinai have developed a lipid nanoparticle system capable of delivering messenger RNA (mRNA) to the brain via intravenous injection, a challenge that has long been limited by the protective nature of the blood-brain barrier.

Innovative blood test shows potential to replace spinal tap for Alzheimer's diagnosis

Up to half of all people living with Alzheimer's Disease in Ireland remain undiagnosed. Now, a new blood test may have the potential to transform patient care, allowing for better diagnosis, earlier interventions and more targeted treatments.

Intracranial hemorrhages linked to higher dementia risk

Weill Cornell Medicine researchers have found that intracranial hemorrhages, or "brain bleeds" caused by a ruptured blood vessel in the brain, double a person's risk of developing dementia later in life.
