Article Synopsis
- Current estimates of genetic variants linked to Parkinson's disease (PD) show limitations and biases across different populations, complicating patient recruitment for clinical trials focused on genetic therapies.
- The Rostock Parkinson's disease (ROPAD) study analyzes data from 12,580 PD patients across 16 countries, revealing that 14.8% had a genetic test positive for PD-related variants, particularly in specific genes like GBA1 and LRRK2.
- Findings indicate higher positivity rates in patients with earlier onset (age ≤ 50) or a positive family history, emphasizing the need for more extensive genetic investigation to improve patient stratification for future clinical trials.
Background: Deep brain stimulation (DBS) has been utilized for over two decades to treat medication-refractory dystonia in children. Short-term benefit has been demonstrated for inherited, isolated, and idiopathic cases, with less efficacy in heredodegenerative and acquired dystonia. The ongoing publication of long-term outcomes warrants a critical assessment of available information as pediatric patients are expected to live most of their lives with these implants.

However, non-motor symptoms of Parkinson's disease and post-mortem histopathology confirm dysfunction in other brain areas, including the locus coeruleus and its associated neurotransmitter norepinephrine. Here, we investigate the role of central norepinephrine-producing neurons in Parkinson's disease by chronically stimulating catecholaminergic neurons in the locus coeruleus using chemogenetic manipulation.

Recent Findings: Over the past 2 years, work from multiple groups has contributed to support an early role of locus coeruleus degeneration and/or hyperactivation in the neurodegenerative process, including a trigger of neuroinflammation. Imaging advances are allowing the quantification of locus coeruleus structural features in vivo, which is critical in the early stages of disease.
Purpose: To develop a new technique that enables simultaneous quantification of whole-brain T , T , , as well as susceptibility and synthesis of six contrast-weighted images in a single 9.1-minute scan.
Methods: The technique uses hybrid T -prepared inversion-recovery pulse modules and multi-echo gradient-echo readouts to collect k-space data with various T1, T2, and weightings.
