Defective metabolism of levodopa in the brain was associated with a decline in the drug's efficacy over time and the adverse effect of dyskinesia among patients with Parkinson disease.
Study Explores Development, Association of Constipation in PD With Other Symptoms
A recent study explored how patients with Parkinson disease who suffer from constipation are more likely to have other nonmotor symptoms than patients without constipation.
How Mutations in the Parkin Gene Affect Quality of Life in Patients With Parkinson Disease
Patients with newly diagnosed Parkinson disease (PD) who carried mutations in the Parkin gene were found to exhibit worse quality of life, longer disease duration, and an earlier age at disease onset than those with PD who did not carry the mutation.
Top 5 Most-Read Parkinson Disease Articles of 2020
The top 5 most-read Parkinson disease stories of 2020 on AJMC.com included the latest insights on treatments such as spinal cord stimulation and the role of dietary management, as well as implications of the coronavirus disease 2019 pandemic.
Tomatoes May Offer Novel Cost-effective Source of Levodopa
Tomatoes metabolically engineered to be enriched by the antiparkinsonian drug levodopa may provide a novel, cost-effective source of the drug for patients with Parkinson disease.
How Does Presence of Essential Tremor Affect Progression of Parkinson Disease?
Among patients with Parkinson disease, a positive history of essential tremor was found to be associated with slower progression of motor and nonmotor symptoms, with no impact observed on survival.
Study Finds Patients With Parkinson Disease at Greater Risk of Death by Suicide
Patients with Parkinson disease were shown to be at greater risk of suicide than matched participants in the general population, according to study findings published last week.
Pandemic-Related Social Isolation Linked With Worsening Symptom Severity, Quality of Life in Parkinson Disease
Amid the coronavirus disease 2019 pandemic, patients with Parkinson disease reporting feelings of loneliness were found to experience greater severity of symptoms.
What We’re Reading: Eli Lilly to Buy Prevail Therapeutics; Extra Doses of Pfizer Vaccine; Breast Cancer Drug Approved
Eli Lilly & Co is set to acquire Prevail Therapeutics Inc for almost $1 billion; Pfizer’s coronavirus disease 2019 vaccine vials found to contain extra doses; a new treatment has been approved for patients with advanced breast cancer.
Review Outlines Dermatologic Implications in Parkinson Disease
Researchers review the association between Parkinson disease and dermatologic disorders, as well as implications that this link may have on the pathophysiological mechanisms underlying Parkinson disease.
How Has Neurological Telemedicine Fared Amid COVID-19?
The effectiveness of telemedicine services among patients with neurological conditions was spotlighted amid the coronavirus disease 2019 (COVID-19) pandemic, particularly how telephone and video consultations have fared in temporarily replacing face-to-face consultations.
Technological Innovations, Challenges to Integration in Parkinson Disease Management
Researchers discuss the latest advances in technology-enabled care under development for Parkinson disease, as well as potential challenges to achieve full integration.
What Can Alleviate Levodopa-Induced Dyskinesia in Parkinson Disease?
Low-frequency transcranial stimulation of the pre-supplementary motor area was found to delay the onset and reduce severity of levodopa-induced dyskinesia in patients with Parkinson disease.
How an Eye Exam May Improve Early Diagnosis of Parkinson Disease
An eye exam paired with artificial intelligence machine learning technology may provide a novel approach to diagnose Parkinson disease in early stages.
Machine Learning Approach May Offer Future Diagnostic Advances in Parkinson Disease
A machine learning approach that works to identify mitochondrial impairments, a potential mechanism underlying the pathogenesis of Parkinson disease (PD), accurately distinguished between patients with PD and healthy controls.
How Tremor Affects Learning Abilities in Patients With Parkinson Disease
Patients with Parkinson disease (PD) who do not experience tremor were found to show improvements in reward learning after taking dopaminergic medication, while those with PD and tremor exhibited no benefit in reinforcement learning.
How Socioeconomic Status Influences Mortality Risk in Patients With Parkinson Disease
Individual-level low socioeconomic status (SES) was found to be significantly associated with increased mortality in Korean patients with Parkinson disease, whereas regional-level SES was not.
A Review of Stem Cell–Based Therapies for Parkinson Disease
Researchers discuss the development and potential of stem cell–based therapies in the treatment of Parkinson disease.
Skin Samples May Improve Earlier Diagnosis of Parkinson Disease
A skin test to detect clumping of alpha-synuclein, an abnormal protein suggested to have a central role in the pathogenesis of Parkinson disease, may assist in improving earlier detection of the condition, according to study findings.
Air Pollution Tied to Higher Hospitalization Risk for PD, Other Neurological Disorders
Air pollution was found to be significantly associated with an increased risk of hospital admissions for several neurological disorders, including Parkinson disease, Alzheimer disease, and other dementias.
Assessing Impact of Parkinson Disease Symptoms on Caregivers, Patients Amid COVID-19
In assessing symptoms of Parkinson disease exacerbated by the coronavirus disease 2019 (COVID-19) pandemic, nonmotor neuropsychiatric and automatic symptoms were noted to particularly affect both patients and their respective caregivers.
Exploring the Clinical Burden of OFF Periods in Parkinson Disease
The Economic Impact of OFF Periods in Parkinson Disease
Examining Chronic Pain in Parkinson Disease
Researchers examine the clinical and pathophysiological mechanisms underlying pain in Parkinson disease.
Spinal Cord Stimulation Found to Reduce Pain, Motor Symptoms in Parkinson Disease
Spinal cord stimulation was found to decrease pain and reduce motor symptoms of Parkinson disease as both a singular therapy and as a salvage therapy after deep brain stimulation therapies proved ineffective.
Novel Study Examines Optimal Drug Balance for Patients With Parkinson Disease
Researchers assess the optimal balance of levodopa in patients with Parkinson disease (PD), which wanes in efficacy as PD progresses and can contribute to uncontrollable, involuntary bodily movements if given in too high of a dosage.
