The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

in the Danish population that was studied when people have had vagotomy x' and the vagus nerve was severed they had a 40% lower incidence of Parkinson's disease
what they found was that those who underwent truncal vagotomy which is the branch of the vagus nerve from the brain to the intestines and the brain to the stomach had a lower incidence of parkinson's disease a significantly lower incidence of parkinson's disease
and there is another correlate to that in terms of epidemiology there is a large study i believe in denmark of people who had super selective versus truncal vagotomy of the vagus nerve meaning cutting the major branches of the vagus nerve versus cutting only selective branches of the vagus nerve which is one of the major nerves that can move compounds and signals in an anterior grade or retrograde fashion from the stomach to the brain or vice versa and when it's doing that if you cut the vagus nerve if you do a truncal vagotomy those people have a much lower incidence of parkinson's disease in the danish population
