Side of Parkinson’s Onset Shapes Cognitive and Emotional Decline

Parkinson’s disease often starts on one side of the body, and new research shows this asymmetry influences how non-motor symptoms progress. Patients whose symptoms begin on the right side tend to experience greater cognitive decline and higher dementia risk.

Stem Cell Grafts Show Promise in Repairing Myelin in MS

A new study reveals that neural stem cell grafts can generate new myelin in the central nervous system, offering hope for treating progressive multiple sclerosis (MS). Researchers showed that induced neural stem cells matured into myelin-producing oligodendrocytes and safely integrated into damaged regions in a mouse model.

Clearing Brain Sugar Stores Could Protect Against Dementia

New research reveals that sugar metabolism in brain cells may be a crucial defense against Alzheimer’s and related dementias. Scientists found that neurons in both flies and human models of tauopathy accumulate excess glycogen, which disrupts cellular stress management when it can’t be broken down.

Cough Medicine Shows Promise in Slowing Parkinson’s Dementia

A clinical trial has revealed that Ambroxol, a common cough medicine in Europe, may help slow cognitive decline in people with Parkinson’s disease dementia. The 12-month study found that the drug stabilized psychiatric symptoms, protected against brain damage, and even improved cognition in genetically at-risk participants.

Brain Stimulation Reverses Synaptic Damage in Alzheimer’s

New research shows that low-intensity repetitive transcranial magnetic stimulation (rTMS) can restore key synaptic structures in mouse models of Alzheimer’s disease. The study found that axonal boutons—sites where neurons form connections—had reduced turnover in Alzheimer’s mice, indicating impaired brain plasticity. After a single rTMS session, the turnover of one bouton type significantly increased, matching levels seen in healthy mice.

Mimicking Exercise in the Brain Could Slow Cognitive Decline

While physical activity is known to slow cognitive decline in Alzheimer’s disease, many patients are unable to exercise due to frailty or advanced symptoms. A new study identifies a specific gene, ATPPIF1, that is reactivated through exercise and supports neuroplasticity in the brain.

Alzheimer’s May Disrupt Nerve Insulation Without Reducing Myelin

New research reveals that Alzheimer's disease may impair nerve function not by reducing myelin, but by altering the proteins at the critical interface between axons and their myelin sheath. Scientists found structural abnormalities in the paranode region, where myelin attaches to axons, including clogged nutrient channels and protein buildup that could block signal transmission.

Brain Criticality May Hold Key to Learning, Memory, and Alzheimer’s

New research proposes a unified theory of brain function based on criticality—a state where the brain teeters between order and chaos, allowing it to learn, adapt, and process information optimally. When the brain strays from this delicate balance, cognitive performance weakens, and neurological disorders such as Alzheimer’s may begin to take hold.

Robotic Heart Transplant Marks Surgical Breakthrough

Surgeons have performed the first fully robotic heart transplant in the U.S., using advanced robotic tools to avoid opening the chest. This technique involved precise incisions and accessing the heart through the preperitoneal space, preserving the chest wall.

Neighborhood Disadvantage Linked to Alzheimer’s Biomarkers and Inflammation

Living in disadvantaged neighborhoods may increase the risk of Alzheimer’s disease by elevating biomarkers associated with inflammation and neurodegeneration. A long-term study of 334 older adults found higher levels of tau and YKL-40, biomarkers linked to Alzheimer’s and brain inflammation, in people from less advantaged areas.

Staying Active Slows Cognitive Decline

Regular physical activity isn’t just good for the body—it protects the brain as we age. A 16-year study of over 13,000 adults found that sustained physical activity significantly slowed cognitive decline.

Shared Genetic Roots of Autism and Heart Disease Found

New research reveals that autism and congenital heart disease may share a common biological basis—tiny cellular structures called cilia. Scientists found that mutations in genes affecting cilia formation disrupt both brain and heart development, helping explain why the two conditions often co-occur.
