Cerebrolysin's effects on language ability in stroke patients with non-fluent aphasia

Effects of Cerebrolysin on Language Ability in Non-fluent Aphasia Patients After Stroke: A Randomized, Placebo-controlled, Double-blinded, Single Center Study

PHASE4 · Yonsei University · NCT06897176

This study tests if adding a medication called cerebrolysin to standard speech therapy can help stroke patients with non-fluent aphasia improve their language skills.

What this trial studies

This study investigates the impact of cerebrolysin on language ability in patients suffering from non-fluent aphasia following a stroke. Participants are divided into two groups: one receiving standard speech therapy combined with cerebrolysin, and the other receiving only standard speech therapy as a control. The study aims to measure changes in language ability using the PK-WAB scores before and after treatment. It focuses on patients in the subacute phase of stroke, where language therapy is crucial for recovery.

Who should consider this trial

Good fit: Ideal candidates are right-handed individuals aged 19 to 90 who have experienced their first ischemic or hemorrhagic stroke and are diagnosed with non-fluent aphasia.

Not a fit: Patients with multiple previous strokes, significant pre-existing neurogenic or psychiatric disorders, or allergies to cerebrolysin may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance language recovery in stroke patients with non-fluent aphasia, potentially improving their quality of life.

How similar studies have performed: While there is ongoing research into treatments for aphasia, the specific use of cerebrolysin in this context is relatively novel and has not been extensively tested.
