Early‐Onset Movement Disorder Syndrome Caused by Biallelic Variants in PDE1B Encoding Phosphodiesterase 1B

open access: yesMovement Disorders, EarlyView.
Abstract Background Breakdown of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) in basal ganglia cells through hydrolysis of diesteric bonds, primarily by PDE10A and PDE1B, is essential for normal human movement. While biallelic loss‐of‐function variants in PDE10A are known to cause hyperkinetic movement disorders, the ...

A Convergent Pathway for Stimulation‐Induced Dyskinesia Following Deep Brain Stimulation

open access: yesMovement Disorders, EarlyView.
Abstract Background Stimulation‐induced dyskinesias (SID) from deep brain stimulation (DBS) of the subthalamic nucleus (STN) and globus pallidus internus (GPi) are uncommon; however, they are increasingly recognized. Once considered transient and indicative of effective neuromodulation, SID are now seen as potential therapy‐limiting side effects, akin ...

Disease‐Modifying Trials in Treated Parkinson's Disease: “Stable Treated” Does Not Equate with Biological Stability

open access: yesMovement Disorders, EarlyView.
Abstract Traditionally, clinical trials of putative disease‐modifying therapies in Parkinson's disease have enrolled untreated patients at the earliest clinical stages of their disease. Due to a number of challenges inherent with this approach, there has been a recent move to a different study design, enrolling patients who are already taking “stable ...

Pregnenolone Reduces L‐Dopa‐Induced Dyskinesias in Female Parkinsonian Monkeys

open access: yesMovement Disorders, EarlyView.
Pregnenolone is the first neurosteroid synthesized from cholesterol in the brain. Ovariectomized female monkeys were tested as a model of women in menopause. They were lesioned with MPTP modeling Parkinson's disease and treated with levodopa (L‐dopa) to induce dyskinesias.
