Monotruncular (Monomelic) CIDP

In this study, the authors describe the clinical, electrophysiological, and radiological features of patients with multifocal chronic inflammatory demyelinating polyneuropathy (CIDP) that presented with monotruncular (monomelic) onset.

Examination and Imaging Correlates of Visual Symptoms in Mild TBI

This study highlights measurable visual and structural changes in patients with mild traumatic brain injury (mTBI). Findings include convergence insufficiency, reduced contrast sensitivity, and occipital cortex changes, despite normal standard imaging and visual field tests. Machine learning discerned mTBI from controls with 72% accuracy, suggesting advanced diagnostics can uncover subtle abnormalities.

Patterns of Brain Atrophy in Memory Disorders

In this multicenter, memory clinic-based cohort targeting earliest at-risk states for dementia of Alzheimer’s type, limbic-predominant and hippocampus-sparing atrophy subtypes were identified. Limbic-predominant atrophy was linked to worse cognitive outcomes over time, including in individuals who were asymptomatic or only had subjective memory symptoms at the time of baseline imaging.

Psychiatric Comorbidities in Persons with Epilepsy

In this systematic review and meta-analysis, the prevalence of most psychiatric disorders was significantly higher in persons with epilepsy than in those without epilepsy. These findings show the high burden of psychiatric comorbidities in persons with epilepsy and underscore the importance of appropriately identifying and treating psychiatric comorbidities in epilepsy patients.

Wildfire Smoke Exposure Is a Risk Factor for Dementia

In this large, open cohort study based on electronic health record data from 2009 to 2019 of dementia-free people older than 60 years of age, exposure to wildfire smoke resulted in an increased incidence of dementia later in life.
