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.

Study advances understanding of mixed protein pathologies in dementia

The aging brain frequently harbors multiple protein pathologies that contribute to Alzheimer's, Parkinson's and other neurodegenerative diseases.

Study identifies new target for Parkinson's disease neuroprotection

Parkinson's disease (PD) is the second most common form of neurodegenerative disease and afflicts more than ten million people worldwide. While current therapies address disease symptoms, they do not prevent the underlying neurodegeneration that drives the disease.

Weill Cornell Medicine receives federal grant to study new gene therapy for Alzheimer's disease

The National Institute on Aging of the National Institutes of Health has awarded a five-year grant initially worth $8.37 million for Weill Cornell Medicine researchers to study a new gene therapy for Alzheimer's disease in people who have a high genetic risk of developing the condition.

NFL players have higher rates of neurodegenerative disease-caused mortality

Mass General Brigham, Boston University, and the Concussion & CTE Foundation cohort study of nearly 20,000 NFL players reveals that players are dying of dementia and Parkinson's disease at much higher rates than the general population.

Investigational drug ameliorates neuronal DNA damage and inflammation in Alzheimer's model

Accumulation of DNA damage in the brain's neurons may contribute to the development of Alzheimer's disease.

New review shows why antidepressants often fail in Alzheimer’s and Parkinson’s depression

A Molecular Psychiatry review shows that depression in Alzheimer’s and Parkinson’s disease may reflect disease-specific molecular, neurotransmitter, inflammatory, and circuit-level disruptions rather than standard depression biology alone. It argues that broad antidepressants often show limited efficacy in these patients and that future trials should use biomarkers, neuroimaging, and symptom profiling to guide targeted treatments.

Study offers insight into how long-term inflammation may contribute to cognitive decline

The King's College London study, published in Nature Communications, offers insight into how long-term inflammation may contribute to cognitive decline in disorders such as Alzheimer's disease, aging, depression, and the lingering neurological effects of viral infections.

Short sleep and poor sleep quality track with Parkinson’s risk

Using CHARLS data from 2011 to 2020, researchers found that sleep duration and self-reported sleep quality were associated with Parkinson’s disease risk in middle-aged and older Chinese adults. Short sleep was linked to higher PD risk, while age-specific patterns suggested a linear association in adults aged ≤60 years and a U-shaped relationship in those aged >60 years.

Study compares different light therapies for treating Alzheimer's disease

The researchers treated 5‑month‑old 5xFAD mice – a model with aggressive amyloid deposition – with 810‑nm light (25 mW/cm² at the scalp, ~6.25 mW/cm² brain dose for CW, and half that for 40‑Hz due to 50% duty cycle) for 10 minutes daily over 37 days.

Rumination carries anxiety into deeper distress for caregivers of dementia patients

A new study from Virginia Tech suggests patterns of repetitive negative thinking explain how anxiety develops into deeper stress for caregivers of people living with dementia, and that mindfulness training may help identify and interrupt that progression.

BCG vaccine may remodel the human brain's immune environment

New research led by Mass General Brigham investigators suggests that the Bacillus Calmette-Guérin (BCG) vaccine - which is delivered through the skin to prevent tuberculosis - may remodel the human brain's immune environment, offering a potential biological explanation for previously observed associations between BCG vaccination and lower Alzheimer's disease risk.

Experimental drug shields nerve cells from damage caused by ALS

Amyotrophic Lateral Sclerosis, or ALS, received widespread awareness in the summer of 2014 thanks to an Ice Bucket Challenge. Millions of people participated in the challenge, drenching themselves in ice cold water to bring visibility to this devastating neurodegenerative disease and generate charitable donations for research.

Blood circRNAs may predict Alzheimer’s before symptoms emerge

Blood-based circular RNAs showed strong potential for identifying biomarker-confirmed Alzheimer’s disease and predicting progression to symptomatic disease. When combined with pTau217, the circRNA model produced the strongest predictive performance, but larger prospective validation is still needed.

Lung tumors hijack nervous system to drive cancer-related cachexia

According to the Cleveland Clinic, a quarter of cancer deaths can be attributed to one source: cachexia. Cachexia is a syndrome that accompanies underlying chronic illness and causes unwanted muscle and fat loss, reducing quality of life and sometimes even limiting treatment options.
