Smoking Linked to Lower Parkinson’s Risk but Higher Mortality

A neurological trade-off. New research finds currently smoking is linked to lower Parkinson's risk, but quitting remains the only way to lower your overall risk of death.

Two Genetic “Hits” Required to Trigger Parkinson’s Neurodegeneration

Researchers find that a mutation in GBA1 must be paired with an ATP13A2 mutation to drive the neurodegeneration seen in Parkinson’s disease.

This shows metabolic pathways in the brain.

Parkinson’s Triggers a Hidden Metabolic Shift

Think Parkinson's weight loss is just about nutrition? New research shows it’s actually a sign of an internal energy engine failure. By switching to a fat-burning "emergency engine," the body tries to compensate for a brain in crisis, making thinness a vital biological warning sign.

Dopamine Acts as a Movement Support System, Not a Speed Controller

Dopamine may not control the force or speed of movements as long believed. Instead, it appears to function as a foundational chemical that enables movement in the first place.

Microplastics Accelerate Alzheimer’s and Parkinson’s Damage

A new review highlights five major ways microplastics can harm the brain, raising concerns that they may worsen neurodegenerative diseases like Alzheimer’s and Parkinson’s. These tiny particles can trigger inflammation, disrupt the blood–brain barrier, generate oxidative stress, impair mitochondria, and damage neurons.

Untreated Sleep Apnea Doubles Parkinson’s Risk

A large analysis of more than 11 million medical records found that people with untreated obstructive sleep apnea face a substantially higher risk of developing Parkinson’s disease over time. Even after accounting for factors like age, obesity, and cardiovascular conditions, those who did not use CPAP were nearly twice as likely to be diagnosed with Parkinson’s as those who treated their apnea.

BrainSTEM Atlas Maps Every Cell of the Developing Human Brain

Scientists have built one of the most comprehensive single-cell maps of the developing human brain. The new BrainSTEM framework analyzed nearly 680,000 fetal brain cells to chart their growth and interactions, offering a detailed reference for studying neuron development.

Gene Behind Child Brain Disorder Also Tied to Parkinson’s Disease

Scientists have discovered that mutations in the EPG5 gene—known for causing the rare childhood disorder Vici syndrome—also increase the risk of Parkinson’s disease and dementia later in life. The gene plays a crucial role in autophagy, the process by which cells clear out damaged material.

Sleep Disorders Predict Parkinson’s or Dementia Years Ahead

Two landmark international studies show that brain biomarkers can predict whether people with REM sleep behaviour disorder (iRBD) will develop Parkinson’s disease or dementia with Lewy bodies (DLB). MRI scans revealed that reduced glymphatic system function signals higher risk for Parkinson’s, while increased free water in the basal nucleus of Meynert predicts progression to DLB.

Oral Bacteria May Trigger Parkinson’s Disease

Scientists have uncovered a direct link between oral bacteria and Parkinson’s disease. They found that Streptococcus mutans, best known for causing cavities, can settle in the gut and release metabolites that reach the brain.

This shows a brain surrounded by viruses and DNA.

Could a Common Virus Help Drive Parkinson’s?

New research suggests a previously harmless virus may be linked to Parkinson’s disease. Scientists detected Human Pegivirus (HPgV) in the brains and spinal fluid of Parkinson’s patients but not in controls, challenging assumptions that the virus is benign.

Overactive Neurons May Drive Parkinson’s Cell Death

A new study shows that overactivation of dopamine-producing neurons in the brain can trigger their degeneration, mirroring what happens in Parkinson’s disease. Using a mouse model, researchers found that chronic activation disrupted daily activity patterns, damaged neuronal axons, and eventually killed cells in the substantia nigra.
