Coeurleophiles and autonomic fanatics, rejoice! I bring you a paper combining both.
Here, we show that orthostatic hypotension must accounted for if attempting to utilize locus coeruleus integrity (with NM-MRI) in the DDx of #Parkinson's and #MultipleSystemAtrophy.

- Exenetide had promise as a disease modifying agent in #Parkinsonsdisease. How about #MSA?
- Single center, *open-label* 48 wk trial lower change in UMSARS score over tme.
- Treatment had no impact on objective findings.
- Placebo/bias effects highly likely.

I am 3 years out of formal training in movement disorders - a two year fellowship - and I only just heard a coherent rationale for why we refer to certain diagnoses as “essential.”

Chronic low thoracic epidural spinal cord stimulation may work in #Parkinsons with severe orthostatic hypotension.

Previously, a different group showed its feasibility in a patient with multiple system atrophy. Many of us thought it may not work in PD.

When Americans raised concerns about RFK Jr.'s anti-vaccine views, he said he was "not gonna take away vaccines from anybody."

But now he's taking them away from millions of mommas and babies.

Vaccine recommendations should be based on science, not RFK Jr.'s political agenda.

No such thing as ‘validation’ of the 'neuronal α-synuclein disease integrated staging system' (NSD-ISS) for #Parkinsons.

It uses αSyn-SAA positivity to anchor an “S-D-G” (Synuclein–Dopamine dysfunction–Genetics) model. Does it hold up? (1/4)

Insightful combination of EEG and iEEG in a patient with epilepsy to study the effects of taVNS on heartbeat-evoked potentials (HEP) in the insula. taVNS enhanced HEPs, but the paper does not say the interaction (vs. sham) was not significant. #neuroskyence

As a biologist, I'm appalled at pride the White House takes in willful ignorance.

In yesterday's executive order about NPR and PBS, their first example of "the trash that passes for `news' at NPR and PBS" is the statement that "banana slugs are hermaphrodites."

But this is unequivocal fact.

Not disagreeing. This is a good piece. It offers some grounded and useful advice for how to advance free thought and good values in today’s autocratic America.

But wow is it depressing. This is where we are at now. An autocratic America.

Still, we will fight on together.
