Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

Spiritual care should be routine for patients with neurological diseases

People living with neurological diseases such as Parkinson's disease, dementia and epilepsy face not only physical decline, but also profound questions about identity, purpose, and meaning.

Unmasking the hyperactive circuitry of early Alzheimer’s

Neuroscientists at King's College London have pinpointed a mechanism behind the increased neural connectivity observed in the very early stages of Alzheimer's disease.

Redefining the "aging brain" through diverse data

Age is more than just one number. While neuroscientists used to think of cognitive aging as a single trendline, they now realize that vast individual differences require a more predictive and personalized approach. As they uncover more factors that affect cognition over time, they are realizing that modeling the aging brain requires more diverse data than traditionally captured.

Modified psilocybin compounds may treat brain disorders with fewer hallucinations

Psilocybin - the psychoactive compound in "magic mushrooms" - is gaining scientific attention for its potential in treating neuropsychiatric conditions including depression, anxiety, substance use disorders and certain neurodegenerative diseases.

Tubulin prevents toxic protein clumps linked to neurodegeneration

Researchers at Baylor College of Medicine have discovered a potential new strategy to fight back against Alzheimer's and Parkinson's diseases, conditions that are linked to the toxic accumulation of Tau and alpha synuclein protein clumps in the brain.

Brain cells amplify important signals to guide focus and navigation

Nerve cells in the brain are constantly bombarded with information from different senses simultaneously. How can the brain prioritize what is most important?

Single dose of CAR-astrocyte therapy halves amyloid levels in mice brains

The new generation of Alzheimer's disease drugs - the first proven to change the course of the disease - typically extend independent living for patients by 10 months.

New report shows primary care readiness for digital cognitive assessment tools

A new Gerontological Society of America (GSA) report summarizes survey findings on the readiness of the primary care workforce to adopt digital cognitive assessments (DCAs) for use in the diagnostic process for cognitive impairment and dementia.

New study shows the brain reactivates memories without reaching conscious thought

Researchers have used brain imaging to show how memories can be reactivated in the brain without them reaching conscious awareness, showing that these memories persist even when we think they have been forgotten.

Seniors defy stereotypes of decline through positive mindsets

Aging in later life is often portrayed as a steady slide toward physical and cognitive decline. But a new study by scientists at Yale University suggests an alternate narrative - that older individuals can and do improve over time and their mindset toward aging plays a major part in their success.

Drug combination shows greater weight loss while preserving muscle mass

A recent research study found that a combination of the GLP-1 receptor agonist semaglutide and bimagrumab, an antibody that blocks activin signaling pathways, results in greater weight loss while also preserving lean mass, such as skeletal muscle and connective tissue.

Machine learning detects early brain changes linked to Alzheimer's disease

Worcester Polytechnic Institute (WPI) researchers have used a form of artificial intelligence (AI) to analyze anatomical changes in the brain and predict Alzheimer's disease with nearly 93% accuracy.

Study reveals a disease-relevant role for tanycytes in neurodegeneration

Accumulation of the protein tau in the brain is one of the hallmarks of Alzheimer's disease. In a paper publishing March 5 in the Cell Press journal Cell Press Blue, researchers report a previously unknown mechanism that appears to enable the build-up of tau.

Study links gut microbiome health directly to ovarian aging processes

A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome (the collection of all bacteria and other microbes present) of the gut and ovarian health and function.

Can brain training prevent dementia? Long-term trial shows speed training with boosters makes a difference

A 20-year follow-up of older adults in the ACTIVE randomized trial linked to Medicare claims found that speed of processing cognitive training with booster sessions was associated with a significantly lower risk of diagnosed Alzheimer’s disease and related dementias. Memory and reasoning training did not show comparable long-term reductions in dementia risk.
