That was not supposed to happen until much later in the disease! 😱

Check out this paper I just dropped on non-motor phenotypes in Parkinson's disease with my bosses

We found that patients with early REM sleep behavior in Parkinson's predicts WORSE non-motor symptoms.

We love how effective DBS is to treat myoclonus dystonia syndrome.

Patients with a SGCE mutation have one of the B E S T responses.

Pauly M shared the case of KCCN2 mutation who did not improve significantly after GPi-DBS.

Should we test SGCE-negative patients before DBS?
