Anxiety, DBS + Ultrasound, Diagnosis Drug and the Use of AI
Greetings from the beautiful city of Istanbul, where the weather is as delightful as the vibrant life here. During my daily exploration of recent scientific literature, I've identified a recurring pattern in the updates on Parkinson's Disease. To keep our information organized and accessible, I will categorize updates into four main types:
Lifestyle Updates
Treatment Updates
Research Updates
Technology Updates
Here are this week’s notable highlights:
Lifestyle Updates
Anxiety and Parkinson's Disease:
A groundbreaking study conducted by Juan Carlos (JC) Bazo Alvarez and his team at UCL has shed light on the connection between anxiety and Parkinson's disease. The research reveals that individuals over the age of 50 who develop anxiety are at least twice as likely to be diagnosed with Parkinson's compared to those without anxiety. The study, which followed participants from the onset of anxiety to one year before a Parkinson's diagnosis, found that symptoms like depression, sleep disturbances, and cognitive impairment significantly increased the risk of developing Parkinson's. This highlights the critical importance of early detection and intervention.

Treatment Updates
Innovations in Deep Brain Stimulation:
Jason Hou, Md Osman Goni Nayeem, Canan Dagdeviren and their team at MIT have introduced a novel approach to deep brain stimulation (DBS) for treating Parkinson’s Disease. Their method utilizes ultrasound via a hair-thin fiber, known as the ImPULS (Implantable Piezoelectric Ultrasound Stimulator), rather than traditional electricity.
This technique promises reduced tissue damage and enhanced neuron stimulation in the substantia nigra, a crucial area for Parkinson's treatment. The research, published in Nature Communications, opens new avenues for safer, more effective brain stimulation therapies and potential drug delivery systems.

Research Updates
Visualizing Parkinson’s Disease Proteins in Living Patients:
Researchers at the National Institutes for Quantum Science and Technology (QST) in Japan have made a significant breakthrough in the visualization of Parkinson’s disease. Their latest study, published in the journal Neuron, introduces a novel imaging agent that can effectively visualize the accumulation of alpha-synuclein protein in the brains of living patients. This protein forms clumps known as fibrils, which are hallmark features of Parkinson’s disease and Lewy body dementia.

Until now, detecting these fibrils in living patients was a major challenge, but the new imaging agent promises to enhance our understanding of the disease progression and assist in the development of targeted therapies. This advancement represents a critical step forward in the diagnosis and study of Parkinson's and related neurodegenerative disorders.

Technology Updates
AI for Early Parkinson's Prediction:
Great Ormond Street Hospital for Children NHS Foundation Trust (GOSH) is pioneering the use of artificial intelligence to forecast Parkinson's disease before symptoms even begin. Researchers have developed a machine learning tool that analyzes a panel of eight blood-based biomarkers, altered in patients with Parkinson's, to provide early diagnosis with high accuracy. This AI tool was tested on patients with rapid eye movement behavior disorder, with results showing that up to 79% of these patients could be predicted to develop Parkinson's up to seven years before any clinical symptoms appear. This breakthrough could transform how we approach Parkinson's disease, allowing for earlier and potentially more effective treatments.
Further information on this revolutionary approach can be found at GOSH AI Parkinson's Prediction.
Thank you for taking the time to read our newsletter. We hope these insights offer valuable knowledge and provoke thought as we continue to explore the complexities of Parkinson’s Disease together.
Looking forward to sharing more next week.
Warm regards,
