A 2026 mechanistic review linked microplastics to 6 proposed Alzheimer’s disease pathways and 6 proposed Parkinson’s disease pathways.1 The calibrated interpretation is that microplastics are biologically plausible brain stressors, but the human evidence does not yet prove that they cause Parkinson’s disease or Alzheimer’s disease. Research Highlights Exposure is widespread: the review cited an estimate …
A 2026 review argues that neurovascular-unit dysfunction may precede amyloid-beta generation in Alzheimer’s disease and then synergize with amyloid deposition, tau pathology, inflammation, and neuronal loss.1 The model is vascular biology plus amyloid biology: blood vessels, barrier integrity, and amyloid deposition can amplify each other early enough to affect dementia risk and progression. Research Highlights …
Microplastics and nanoplastics (MNPs) from the breakdown of plastic materials pollute the environment and make their way into the human body, raising concerns over potential health impacts. Research shows that microplastics and nanoplastics are able to cross the blood-brain barrier in mice within 2 hours of ingestion. Key Facts: Polystyrene nanoparticles with a size of …
Recent research reveals that combining fish oil and choline supplementation may have synergistic effects in boosting levels of brain docosahexaenoic acid (DHA) and memory enhancement in middle-aged mice. Key Facts: Combining fish oil and choline increased DHA levels in the brain more than either supplement alone in mice. The combination upregulated expression of key fatty …
Is GABA an effective treatment for anxiety disorder? Many people believe so. When dealing with anxiety, everyone is different. What works for one person may not work for you. If you have tried therapy and talked to a psychologist, but cannot overcome anxiety on your own, you may seek out alternative types of treatment. One …
