Recently, a study from Oregon Health & Science University showed that cerebrospinal fluid flows into the brain through distinct channels called perivascular spaces and then into the brain tissue, a discovery that aligns with the glymphatic system described in mice.

Memory loss is the most recognized symptom of dementia, particularly in Alzheimer's disease, but experts point out other early warning signs that are significant for types of dementia where forgetfulness isn't primary.

Here are five other common red flags to look out for.

We recently wrapped up our second Industry Roundtable at the Movement Disorders Society Congress in Philadelphia.

Our focus? Advancing clinical trials for neuroprotective treatments targeting synucleinopathies.

Wearable tech may help track non-motor Parkinson’s symptoms like sleep issues linked to REM sleep behavior disorder. NAPS will soon begin a pilot study at select sites.

A study suggests voice analysis in RBD patients may help detect early Parkinson’s progression. AI monitoring of voice, movement, and walking patterns shows promise but needs further validation.

The New York Times delves into the rise of sleep optimization, noting the risks of 'orthosomnia'—an excessive focus on perfect sleep that can backfire. While aids like magnesium and gadgets help some, experts emphasize simpler habits.

A study by Dr. Michael Howell and NAPS team at University of Minnesota found key differences between RBD triggered by antidepressants (Serotonergic RBD) and idiopathic RBD (iRBD). Follow-up ongoing to assess neurodegenerative risks.

A recent study reported on two individuals with RBD treated with acetyl-DL-leucine (ADLL). Both had significantly decrease in severity of RBD symptoms, with improvements sustained for over 18 months. More intriguingly, both individuals had change in dopamine transporter imaging and brain imaging patterns opposite from what would be expected for Parkinson's disease, suggesting that ADLL might have a neuroprotective effect.

Researchers at Hospital Clinic of Barcelona, Spain analyzed cerebrospinal fluid (CSF) from 148 patients with isolated REM sleep behavior disorder (iRBD) to find biological signals linked to neurodegenerative diseases. The study team used advanced techniques to measure proteins, including misfolded alpha-synuclein and Alzheimer’s markers, and tracked participants longitudinally to determine whether these markers may predict disease development.

Researchers found that higher levels of belly and arm fat are associated with increased risk of developing Alzheimer's and Parkinson's diseases, especially among those with lower muscle strength. The study showed that individuals with high belly fat had a 13% higher risk, and those with high arm fat had an 18% higher risk of these neurodegenerative diseases compared to their counterparts with lower fat levels.

A recent study evaluated the effects of fecal transplant in improving clinical symptoms in PD. This study showed that fecal transplant did not lead to meaningful improvement in Parkinson's disease. The role of the gut in PD is still an interesting concept in how the disease evolves and more studies are needed to evaluate interventions that are based on altering gut flora as a possible therapeutic intervention.

The notion that night owls who stay up late struggle to be productive during the day might need rethinking.

Processed red meat has been found to raise the risk of dementia according to preliminary research presented at the Alzheimer's Association International Conference.

The study tracked more than 130,000 adults in the U.S. for up to 43 years. During that period, 11,173 people developed dementia. Those who consumed about two servings of processed red meat per week had a 14% greater risk of developing dementia compared to those who ate fewer than three servings per month.

Dreaming might help us practice handling threats, process emotions, and make sense of information. While many aspects of dreaming remain mysterious, researchers have uncovered some surprising insights. Curious about what you know about dreaming?
