AI Article Synopsis
- The study aimed to assess how unilateral hemispheric strokes affect voiding dysfunction by comparing urodynamic parameters across different patient groups.
- A total of 69 stroke patients with lower urinary tract symptoms were analyzed, but key urodynamic measures showed no significant differences between patients with dominant, non-dominant, and bilateral lesions.
- The results indicate that the laterality of ischemic lesions in the brain does not correlate with variations in lower urinary tract symptoms, as no significant differences were found among the groups.
Article Abstract
Objectives: To determine the effect of unilateral hemispheric lesion on voiding dysfunction by comparing urodynamic parameters in dominant, non-dominant and bilateral hemispheric stroke patients.
Methods: We retrospectively reviewed the medical records of patients from a magnetic resonance imaging and urodynamic study. We identified 69 cases among 192 stroke patients who had undergone urodynamic study due to lower urinary tract symptoms from June 2003 to December 2008.
Results: Among the analyzed variables in the urodynamic study, total bladder capacity, voided volume, postvoid residual urine volume, maximum flow rate, average flow rate, detrusor pressure at the maximum flow rate, and bladder compliance did not show statistically significant differences among dominant, non-dominant and bilateral hemispheric stroke patients groups (P > 0.05). The dominant hemispheric stroke group had detrusor overactivity in 64.2% of cases and detrusor underactivity in 35.8%; the non-dominant hemispheric stroke group had detrusor overactivity in 66.7% of cases and detrusor underactivity in 33.3%; and the bilateral stroke group had detrusor overactivity in 60.0% of cases and detrusor underactivity in 40.0% (P = 0.946).
Conclusion: Urodynamic findings cannot be characterized by the laterality of the unilateral hemispheric ischemic lesion. There are no significant differences in lower urinary tract symptoms between dominant, non-dominant and bilateral hemispheric ischemic stroke patients.

Pediatric patients with moyamoya disease frequently show rapid progression with a high risk of stroke. Indirect revascularization is widely accepted as a surgical treatment for pediatric moyamoya disease, but it does not augment cerebral blood flow immediately, which leaves patients at risk for stroke peri-operatively. This delay in flow augmentation may make adding direct bypass the better option.

Acute ischemic stroke (AIS) is a leading cause of mortality and disability worldwide, with early and accurate diagnosis being critical for timely intervention and improved patient outcomes. This retrospective study aimed to assess the diagnostic performance of two advanced artificial intelligence (AI) models, Chat Generative Pre-trained Transformer (ChatGPT-4o) and Claude 3.5 Sonnet, in identifying AIS from diffusion-weighted imaging (DWI).

Background: Perinatal brain injury is a leading cause of developmental disabilities, including cerebral palsy. However, further work is needed to understand early brain development in the presence of brain injury. In this case report, we examine the longitudinal neuromotor development of a term infant following a significant loss of right-hemispheric brain tissue due to a unilateral ischemic stroke.

Personalized prediction of stroke outcome using lesion imaging markers is still too imprecise to make a breakthrough in clinical practice. We performed a combined prediction and brain mapping study on topographic and connectomic lesion imaging data to evaluate (i) the relationship between lesion-deficit associations and their predictive value and (ii) the influence of time since stroke. In patients with first-ever ischaemic stroke, we first applied high-dimensional machine learning models on lesion topographies or structural disconnection data to model stroke severity (National Institutes of Health Stroke Scale 24 h/3 months) and functional outcome (modified Rankin Scale 3 months) in cross-validation.

Objective: This study aims to observe the effect of enrichment rehabilitation (ER) on cognitive function in post-stroke patients and to clarify its underlying mechanism.
Methods: Forty patients with post-stroke cognitive impairment (PSCI) meeting the inclusion criteria were randomly assigned to two groups: conventional medical rehabilitation (CM group) and ER intervention (ER group). All patients underwent assessments of overall cognitive function, attention function, and executive function within 24 h before the start of training and within 24 h after the 8 weeks of training.
