Higher BMI Linked to Longer Survival After a Dementia Diagnosis
Summary: A long-term study of more than 4,500 older adults reveals that individuals who are overweight or obese when diagnosed with dementia exhibit a significantly lower risk of death than…
Adults With ADHD Face Higher Long-Term Dementia Risk
Summary: A massive study of more than 187,000 older adults enrolled in the NIH’s All of Us Research Program reveals that adults with attention-deficit/hyperactivity disorder (ADHD) face more than quadruple…
Early DBS Protects Cognition in Genetic Parkinson’s
Summary: A multi-center international study reveals that the timing of Deep Brain Stimulation (DBS) surgery is the deciding factor in preserving cognitive function for Parkinson’s disease patients carrying a GBA1…
Study of Brain Immune Cells Reveals New Clues to Alzheimer’s Disease Progression
Summary: Researchers have mapped over 830,000 brain immune cells, discovering a protective subtype of microglia that expands as Alzheimer’s disease progresses. Driven by the TREM2 molecular pathway, these cells actively…
Regenerative Astrocytes Repair Brain Damage
Summary: Researchers discovered a previously unknown mechanism through which the adult mammalian brain repairs itself following focal injuries or autoimmune damage. Using two-photon microscopy and longitudinal gene mapping in living…
Exercise Shields Dopamine Neurons in Parkinson’s
Summary: Researchers synthesized evidence from 129 studies detailing how exercise-induced muscle signaling protects against Parkinson’s disease (PD) pathology. The authors examine the biological impact of sarcopenia, the progressive loss of…
Phase 1 Trial Validates Anti-PD-L1 Antibody for Alzheimer’s
Summary: Researchers announced the successful completion of a Phase 1b clinical trial for a novel immunotherapy for Alzheimer’s disease. The trial evaluated IBC-Ab002, a humanized anti-PD-L1 monoclonal antibody specifically engineered…
Brain PET Scans Link Late-Onset Psychosis to Tau and Amyloid
Summary: A new study demonstrates that first-episode hallucinations and delusions appearing after age 40 are frequently driven by underlying neurodegenerative pathology. Using molecular positron emission tomography (PET) imaging, the team…
Consistent Daily Routines Reduce Physical Pain and Depression
Summary: A study reveals that maintaining a consistent daily routine can significantly reduce physical pain and ease symptoms of depression, offering a accessible strategy for improving overall quality of life,…
