[Neurodynamic speech disorders in the acute ischemic stroke].

Area of Science:

• Neurology
• Speech Pathology
• Stroke Research

Context:

• Ischemic stroke (IS) in the carotid system can lead to various speech impairments.
• Differentiating between cortical aphasia and neurodynamic speech disorders is crucial for understanding recovery patterns.

Purpose:

• To compare the clinical features and recovery dynamics of neurodynamic speech disorders with cortical aphasia post-ischemic stroke.
• To evaluate the regression patterns of speech disorders in patients with IS in the carotid system.

Summary:

• This study analyzed 268 patients with ischemic stroke, categorizing them into those with cortical aphasia (63.8%) and neurodynamic speech disorders (36.2%).
• Patients with neurodynamic speech disorders demonstrated significantly better and faster recovery (p=0.001), with less impact on the sensory component of speech compared to cortical aphasias.
• Motor and sensorimotor deficits were equally frequent in neurodynamic speech disorders, while cortical lesions more often affected the receptive speech areas.

Impact:

• Findings suggest neurodynamic speech disorders have a more favorable prognosis for speech recovery after ischemic stroke.
• Highlights the importance of distinguishing between these speech disorder types for targeted therapeutic interventions and patient counseling.
• Provides insights into the differential impact of stroke on various speech components, aiding in clinical assessment and management strategies.
