Unwanted Weight Gain or Weight Loss During the Pandemic? Blame Your Stress Hormones

A recent study found 42% of participants gained, on average, 29 lb of unwanted weight during the pandemic, with people gaining 1.5lb per month. Researchers say a combination of stress, hormones, and dwindling motivation to exercise during the lockdowns may be to blame. Read More

Hunger Hormone Impacts Memory

The hunger hormone ghrelin doesn't just influence where and when animals eat, it also appears to have an impact on memory. Disrupting signaling of ghrelin to the vagus nerve caused rats to forget they had just eaten, even though the animals remembered they had just had access to food. Findings suggest disrupted ghrelin signaling could negatively impact episodic memory. Read More

Earbud-like nerve stimulator shows promise for relieving indigestion

For the 15% of American adults who suffer from frequent indigestion or functional dyspepsia, a new, non-invasive treatment may provide some relief. Respiratory-gated Auricular Vagal Afferent Nerve Stimulation (RAVANS), a form of taVNS, delivers short pulses of painless electrical current to the vagus nerve in tune with respiratory rhythms. The device can modulate the stomach's response to food ingestion, which is often impaired in those with functional dyspepsia. Read More

Where does Parkinson’s disease start? In the brain or gut? Or both?

Lewy body disorders, including Parkinson's disease and Lewy body dementia, comprise of two distinct subtypes. One subtype originates in the peripheral nervous system (PNS) of the gut and spreads to the brain. The other originates in the brain, or enters the brain via the olfactory system, before spreading to the brainstem and PNS. Read More

New research shows Parkinson’s disease origins in the gut

A new study adds to the growing body of evidence that Parkinson's disease may start in the gut. Researchers found gut-to-brain propagation of alpha-synuclein spread via the vagus nerve. The study provides a more accurate model of Parkinson's progression and could lead to new treatments to halt or prevent this neurodegenerative disease. Read More
