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 provides evidence that Parkinson’s disease (PD) is associated with thinning of specific retinal layers that can be detected years before diagnosis. Key facts: Individuals with Parkinson’s disease (PD) had thinner retinal ganglion cell and inner plexiform layers compared to controls. Thinning of the inner nuclear layer, which contains dopamine cells, was also seen …
While people will always be in search of specific diets to help them lose weight, in recent years there is an increasing interest in how certain foods affect the human brain. It is estimated that there are currently over 5 million individuals in the United States that have been diagnosed with Alzheimer’s disease, and dietary …
Anyone living in a big city that has taken a vacation to experience nature (e.g. a cabin in the woods) can often detect a stark contrast in air quality. In the big city, the air you’re breathing in often smells dull and polluted, and you may sense that it’s taking a toll on your health. …
In recent years, increasing evidence has suggested that certain types of commonly prescribed medications may cause increased risk of developing dementia. This ranges from drugs used to treat anxiety (e.g. Xanax) to over-the-counter drugs (e.g. Benadryl). A majority of these medications tend to depress activity in the CNS and help minimize arousal and/or anxiety. Dementia …
