Understanding how brain processes affect sentence production in people with aphasia

Neurocognitive Mechanisms of Sentence Production Impairment in Aphasia

NA · University of Maryland, College Park · NCT06405594

This study is trying to understand how the brain works when people with post-stroke aphasia struggle to form sentences, in hopes of finding better ways to help them communicate.

What this trial studies

This research aims to explore the neurocognitive mechanisms behind sentence production impairments in individuals with post-stroke agrammatic aphasia. By investigating how lexical, grammatical, motoric, and cognitive processes interact during sentence production, the study seeks to identify the neural dynamics that contribute to communication difficulties. The findings could inform the development of more effective interventions for improving communication in individuals affected by aphasia. The study will involve both individuals with acquired aphasia and neurotypical adults to provide a comparative analysis.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with acquired aphasia following a left hemisphere brain injury, as well as neurotypical adults aged 18-30 or over 60.

Not a fit: Patients with prior neurological or psychiatric conditions or those who do not speak English fluently may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could lead to improved therapeutic strategies for individuals with aphasia, enhancing their communication abilities and overall quality of life.

How similar studies have performed: While there have been studies focusing on aphasia, this specific approach to understanding the neurocognitive mechanisms is novel and has not been extensively tested.
