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.

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.

New microscope captures 3D blood flow and oxygenation at single-cell resolution

The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural tissue like electrical wires.

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.

Protein linked to Parkinson's may drive faster Alzheimer's disease progression in women

Alzheimer's-related brain changes progressed up to 20 times faster in women who also had abnormal levels of a Parkinson's-related protein, according to a Mayo Clinic study published in JAMA Network Open.

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.

Low‑dose oral lithium may help slow the decline of verbal memory, trial suggests

Lithium-a decades-old treatment for bipolar disorder-may hold potential neuroprotective benefits beyond mood stabilization.

Investigating microglia’s role in Alzheimer’s pathology

Announcing a new article publication for BIO Integration journal. Alzheimer's disease (AD) is a neurodegenerative disorder and the leading cause of dementia worldwide. Microglia, as central nervous system (CNS) resident macrophages, are key to AD pathology. Indeed, microglia aggregation around amyloid-β (Aβ) deposits is an AD hallmark.

Machine learning predicts who will decline faster in Alzheimer’s disease using routine clinic data

Researchers developed and validated ElasticNet machine learning models that predict 12-month MMSE and BADL outcomes in Alzheimer’s disease and mild cognitive impairment using routinely collected clinical data. The cognitive model demonstrated external validation in ADNI, showing that individualized progression forecasting is feasible without biomarkers or neuroimaging.
