Olfactory dysfunction, dysautonomia, mood disturbance, and motor deficits disproportionate to dopaminergic denervation may serve as markers of amyloid-β positivity in newly diagnosed Parkinson disease.

The European Commission approved modified-release carbidopa/levodopa capsules, already available in the US as Crexont, for adults with moderate to severe motor fluctuations.

An analysis of more than 311,000 UK Biobank participants identified 13 pairs and 14 triplets of risk factors with significant additive interactions for late-onset Parkinson disease, with several potentially modifiable factors emerging as targets for prevention.

Findings from a phase 1 study showed that bilateral putaminal delivery of AAV2-GDNF using convection-enhanced delivery was well tolerated over 5 years, although exploratory clinical measures did not demonstrate significant improvements from baseline.

Full results from the phase 3 TEMPO-2 trial, published in Lancet Neurology, showed that flexible-dose tavapadon significantly improved motor symptoms and daily function in people with early Parkinson disease.

A recently published phase 2 trial showed that CBD/THC cannabis oil failed to ease chronic pain or nonmotor symptoms versus placebo among patients with Parkinson disease.

Investigators independently tracked the 6 patients treated in a Parkinson disease gene therapy trial that was abandoned mid-study after its sponsor became insolvent, finding a reassuring safety profile and mixed signals of motor benefit through up to 3 years.

Topline findings from the Phase 2 SUNRISE-PD study showed statistically significant improvements in clinical measures, inflammatory biomarkers, and exploratory neurodegeneration markers among patients with early Parkinson disease treated with bezisterim.
