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.

Scientists uncover how herpes virus fuels Alzheimer’s disease

Herpesvirus infection may contribute to Alzheimer’s disease through transposable element activation and neuroinflammation.

Patients favor non-invasive neuromodulation for neurological and mental health disorders

A new study, led by experts at the University of Nottingham, has found that patients who need treatment for neurological and mental health disorders, would favour non-invasive neuromodulation interventions over current interventions such as pharmaceutical drugs.

Study highlights increase in VZV-induced CNS infections and dementia risk

Researchers from Fujita Health University, Japan, observed a rise in adult central nervous system (CNS) infections, primarily aseptic meningitis caused by the varicella zoster virus (VZV), post-2019. The researchers highlighted the potential of zoster vaccination to reduce CNS infections.

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.

Study shows how herpes viruses contribute to Alzheimer's disease in aging brains

Researchers from Cleveland Clinic's Genome Center outlined the pathway human herpes simplex virus-1 (HSV1) can use to contribute to Alzheimer's disease in aging brains.

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."
