Summary: Post-operative cognitive dysfunction (POCD) is a common neurological complication in older individuals following anesthesia/surgery, characterized by memory loss and accompanying abnormal emotions, behaviors, and language without consciousness disorder. The diagnosis of POCD often involves the evaluation of perioperative cognitive function using neuropsychological tests.

Summary: Diabetes is highly correlated with Alzheimer's disease and can cause complications that make it difficult to record neuronal activities in the brain tissue of diabetic patients. Researchers have developed a 4-mu m-tip diameter needle-electrode device that allows for electrophysiological recording in diabetic mice, reducing tissue injury and glial cell responses.

Summary: Intracellular recording of action potentials is crucial for studying disease mechanisms and electrophysiological studies. Current strategies include 3D nanoelectrodes and transient electroporation, but both have limitations. In this study, an advanced cell-based biosensing platform using electroporation is proposed, which provides consistent, high-quality recordings and allows real-time feedback.

Summary: This study used population-level data to develop and validate predictive models for postoperative mortality in patients with cirrhosis. The VOCAL-Penn models showed excellent discrimination and calibration compared to existing tools like MRS, MELD, MELD-Na, and CTP scores. These models could assist in preoperative risk assessment and patient selection for surgical procedures.

Summary: This study aimed to investigate the effects of high-intensity exercise on information processing and movement execution in individuals with Parkinson's disease. The results showed that aerobic exercise improved movement execution and information processing, with improvements persisting even after the exercise intervention ceased. Antiparkinsonian medication improved motor execution, but not information processing. The findings suggest that high-intensity exercise may enhance neural processing and non-motor pathways, providing a potential candidate for disease modification.

Summary: The study identified three cognitive subtypes of ET patients undergoing DBS, with 27.4% meeting criteria for MCI. The majority of MCI cases were in the Low Executive or Low Memory Multi-Domain groups, with the latter having a higher percentage of members classified as MCI. Future work should focus on examining these subgroups for progression to dementia.

Summary: This study compared the severity of mood symptoms in PD, ET, and HC groups and examined the relationship between mood and cognition. The results showed that both PD and ET groups reported more mood symptoms and lower cognitive scores compared to the HC group. The relationship between mood and cognition differed between PD and ET groups.

Summary: Despite advances in treatment, neuromodulation, such as deep brain stimulation, has not gained widespread adoption as a potential therapy for psychiatric diseases. In 2016, the American Society for Stereotactic and Functional Neurosurgery organized a meeting to discuss the future path forward. A follow-up meeting in 2022 aimed to review the current state of the field and identify barriers and milestones for progress.

Summary: Objective measures of disease progression using the Purdue Pegboard Test (PPT) were conducted in patients with Parkinson's disease (PD), atypical Parkinsonism, and healthy controls. The decline in PPT performance in PD patients correlated with motor symptom progression, while no such decline was seen in controls. Neuroimaging measures from the basal ganglia were significant predictors of PPT performance in PD, and cortical, basal ganglia, and cerebellar regions were predictors for atypical Parkinsonism. Accelerometry in PD patients showed diminished acceleration range and irregular patterns, which correlated with PPT scores.

Summary: Using the novel data-driven method DEBM, this study determined the sequence of several common biomarker changes in Parkinson's disease (PD). The left putamen was found to be the earliest biomarker to become abnormal, followed by the right putamen, CSF alpha-synuclein, right caudate, left caudate, and serum NfL. The estimated disease stages showed significant differences between PD and healthy controls, and achieved a high accuracy for distinguishing PD from HC.

Summary: This study aimed to investigate the incidence and risk factors for institutionalisation in Parkinson's disease (PD) and atypical parkinsonism (AP). The study found that institutionalisation was more frequent in AP compared to PD and controls. Age, poorer cognition, and more-severe parkinsonian impairment were independent predictors of institutionalisation.
