Movement Disorders in Developmental and Epileptic Encephalopathies

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Monogenic developmental and epileptic encephalopathies (DEE) frequently feature co‐occurring movement disorders. Gene discovery has expanded epilepsy‐dyskinesia syndromes (EDS) from classic associations such as stereotypies in Rett syndrome to PRRT2‐related infantile seizures with paroxysmal dyskinesia and crouched gait in SCN1A ...

Phenomenology of levodopa-induced dyskinesia

, 2014
Levodopa has been effective against the motor features of Parkinson's disease for several decades. However, it is observed that long-term treatment with levodopa can be complicated by the development of various types of response fluctuations as well as ...

Levodopa-Induced Dyskinesia Is Related to Indirect Pathway Medium Spiny Neuron Excitotoxicity: A Hypothesis Based on an Unexpected Finding

Parkinson's Disease, 2016
A serendipitous pharmacogenetic finding links the vulnerability to developing levodopa-induced dyskinesia to the age of onset of Huntington’s disease. Huntington’s disease is caused by a polyglutamate expansion of the protein huntingtin.

Data‐Driven Insights into Hyperkinetic Disorders in Neurodevelopmental Syndromes and Epileptic Encephalopathies

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Childhood‐onset hyperkinetic movement disorders occur in a range of genetic conditions. Recently, there has been an increase in recognition of hyperkinetic movement disorders, mainly dystonia, chorea and dyskinesia, with monogenic conditions associated with neurodevelopmental delay (NDD) and also with developmental and epileptic ...

Tracking Genetic Parkinson's Disease with Molecular Imaging: A Systematic Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) is a worldwide, complex neurodegenerative disorder influenced by both genetic and environmental factors. Around 15–20% of PD cases are linked to genetic mutations, providing insights into the disease's pathogenesis.

7 T MRI Connectivity‐Guided Reprogramming Improves Deep Brain Stimulation Motor Outcome in Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an established treatment for Parkinson's disease (PD). Using 7‐Tesla (7 T) MRI connectivity analysis to visualize the patient‐specific STN motor subdivision, we hypothesize that reprogramming patients who are stimulated outside of this subdivision can improve their ...

Continuous Intrajejunal Levodopa–Carbidopa Infusion in Parkinson's Disease Associated with 22q11.2 Deletion Syndrome: A Case Series

Movement Disorders Clinical Practice, EarlyView.
Abstract Background 22q11.2 deletion syndrome (22q11DS) is a multisystem genetic disorder associated with a significantly increased risk of early‐onset Parkinson's disease (EOPD). Management is challenging because psychiatric and cognitive comorbidities often limit advanced therapies such as deep brain stimulation (DBS). Cases We report 2 patients with

Involvement of Autophagy in Levodopa‐Induced Dyskinesia

, 2021
International audienceBackgroundAutophagy is intensively studied in cancer, metabolic and neurodegenerative diseases, but little is known about its role in pathological conditions linked to altered neurotransmission.

Altered D1 dopamine receptor trafficking in parkinsonian and dyskinetic non-human primates

Neurobiology of Disease, 2007
Dyskinesias represent a debilitating complication of levodopa therapy for Parkinson's disease (PD). While we recently demonstrated that levodopa-induced dyskinesia results from increased dopamine D1 receptor-mediated transmission, we also questioned the ...

Machine Learning Prediction of Hoehn and Yahr Scores at 5‐Years Post‐123I‐Ioflupane SPECT Imaging in a Real‐World Parkinson's Disease Dataset

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) progression is highly heterogeneous, complicating clinical management and prognostication. While machine learning models have been developed using research datasets such as Parkinson's Precision Medicine Initiative (PPMI) and Parkinson's Disease Biomarkers Program (PDBP), their clinical translatability is ...
