Abstract Recent advancements in Parkinson’s disease (PD) drug development have been significantly driven by genetic research. Importantly, drugs supported evidence are more likely to be approved. While genome-wide association studies (GWAS) a powerful tool nominate genomic regions associated with certain traits or diseases, pinpointing the causal biologically relevant gene is often challenging. Our aim was prioritize genes underlying PD GWAS signals. The polygenic priority score (PoPS) similarity-based prioritization method that integrates information from MAGMA gene-level tests and than 57,000 features, including expression, biological pathways, protein-protein interactions. We applied PoPS data largest published East Asian- European-ancestries. identified 120 independent associations P < 5×10 −8 prioritized 46 across these loci based on their scores, distance signal, presence of non-synonymous variants credible set. Alongside well-established ( e.g., TMEM175 VPS13C ), some which targeted ongoing clinical trials i.e. , SNCA LRRK2 GBA1 we plausible mechanistic link pathogenesis RIT2, BAG3 SCARB2 ). Many hold potential for repurposing novel therapeutic developments i.e., FYN, DYRK1A, NOD2, CTSB, SV2C, ITPKB Additionally, potentially druggable relatively unexplored XPO1, PIK3CA, EP300, MAP4K4, CAMK2D, NCOR1, WDR43 high-confidence list strong links may represent our next-best candidates disease-modifying therapeutics. hope findings stimulate further investigations preclinical work facilitate programs.

Epilepsy, a prevalent neurological disorder characterized by recurrent seizures, affects millions worldwide, with significant proportion resistant to pharmacological treatments. Surgical interventions have emerged as pivotal in managing drug-resistant epilepsy (DRE), aiming reduce seizure frequency or achieve freedom. Traditional resective surgeries evolved technological advances, enhancing precision and safety. Neurostimulation techniques, such responsive neurostimulation (RNS) deep brain stimulation (DBS), now provide personalized, real-time management, offering alternatives traditional surgery. Minimally invasive ablative methods, laser interstitial thermal therapy (LITT) Magnetic Resonance-guided Focused Ultrasound (MRgFUS), allow for targeted destruction of epileptogenic tissue reduced risks faster recovery times. The use stereo-electroencephalography (SEEG) robotic assistance has further refined surgical precision, outcomes. These advancements mark paradigm shift towards medicine care, promising improved management quality life patients globally. This review outlines the latest innovations surgery, emphasizing their mechanisms clinical implications improve outcomes DRE.

This study investigated the subthalamic nucleus (STN) function and deep brain stimulation (DBS) effects on single-unit activity (SUA) in Parkinson's disease (PD) patients with dysarthria. After presurgical speech analysis, we recorded STN neuronal activities while PD (n = 16) articulated Chinese Pinyin consonants. The consonants were categorized by manner place of articulation for SUA cluster analysis. cohort was then divided into normal dysarthria groups based diadochokinetic (DDK) assessments. patterns, represented mean firing rate (FR), peak time, response intensity during articulation, analyzed compared between two groups. Finally, a 7 included to test pattern changes following intraoperative DBS. Clustering analysis patterns demonstrated that neurons encode grouping same distinct clusters. Using k-means clustering, further classified SUAs waveform types: negative spikes (type 1) positive 2). Dysarthria exhibited an increased FR type 1 reduced 2 spikes.
