Parkinson's disease is an idiopathic, slowly progressive disorder of the central nervous system characterized by resting tremor, muscular rigidity, slow and decreased movement (bradykinesia), and postural instability. In the United States, Parkinson's disease is the fourth most common neurodegenerative disorder in the elderly, affecting an estimated half a million people. Oral health care providers can expect to be called upon to care for patients with this progressively debilitating disease. To provide competent care to patients with Parkinson's disease, clinicians must understand the disease, its treatment, and its impact on the patient's ability to undergo and respond to dental care.

Harmonious ageing: a narrative review of music therapy in the biomedical literature.
Eur Geriatr Med
January 2025
School of Medicine, Trinity College Dublin, Dublin, Ireland.
Purpose: As the global population of older adults rises, the United Nations Decade of Healthy Ageing (2021-2030) advocates for disease prevention, management, and enhancing overall wellbeing in older adults. We reviewed the MEDLINE literature under the MeSH term "music therapy" (MT), for its role in promoting healthy ageing.
Methods: A systematic search of the MEDLINE biomedical database (Ovid) was conducted using "MT" and "Ageing" as keywords, retrieving relevant full-text studies in English.

Adaptive deep brain stimulation (DBS) provides individualized therapy for people with Parkinson's disease (PWP) by adjusting the stimulation in real-time using neural signals that reflect their motor state. Current algorithms, however, utilize condensed and manually selected neural features which may result in a less robust and biased therapy. In this study, we propose Neural-to-Gait Neural network (N2GNet), a novel deep learning-based regression model capable of tracking real-time gait performance from subthalamic nucleus local field potentials (STN LFPs).

Loss-of-function mutations in PARK7, encoding for DJ-1, can lead to early onset Parkinson's disease (PD). In mice, Park7 deletion leads to dopaminergic deficits during aging, and increased sensitivity to oxidative stress. However, the severity of the reported phenotypes varies.

Distinguishing between Parkinson's disease (PD) and essential tremor (ET) can be challenging sometimes. Although positron emission tomography can confirm PD diagnosis, its application is limited by high cost and exposure to radioactive isotopes. Patients with PD exhibit loss of the dorsal nigral hyperintensity on brain magnetic resonance imaging (MRI).

Department of Molecular Pathology, IRCCS Neuromed, Pozzilli, Italy.
Metabotropic glutamate (mGlu) receptors are candidate drug targets for therapeutic intervention in Parkinson's disease (PD). Here we focused on mGlu3, a receptor subtype involved in synaptic regulation and neuroinflammation. mGlu3 mice showed an enhanced nigro-striatal damage and microglial activation in response to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).
