Background: Aphasia affects one third of acute stroke patients. There is a considerable spontaneous recovery in aphasia, but impaired communication ability remains a great problem. Communication difficulties are an impediment to rehabilitation. Early treatment of the language deficits leading to increased communication ability would improve rehabilitation. The aim of this study is to elucidate the efficacy of very early speech and language therapy (SLT) in acute stroke patients with aphasia. Methods: A prospective, open, randomized, controlled trial was carried out with blinded endpoint evaluation of SLT, starting within 2 days of stroke onset and lasting for 21 days. 123 consecutive patients with acute, first-ever ischemic stroke and aphasia were randomized. The SLT treatment was Language Enrichment Therapy, and the aphasia tests used were the Norsk grunntest for afasi (NGA) and the Amsterdam-Nijmegen everyday language test (ANELT), both performed by speech pathologists, blinded for randomization. Results: The primary outcome, as measured by ANELT at day 21, was 1.3 in the actively treated patient group and 1.2 among controls. NGA led to similar results in both groups. Patients with a higher level of education (>12 years) improved more on ANELT by day 21 than those with <12 years of education (3.4 vs. 1.0, respectively). In 34 patients in the treatment group and 19 in the control group improvement was ≧1 on ANELT (p < 0.05). There was no difference in the degree of aphasia at baseline except for fluency, which was higher in the group responding to treatment. Conclusions: Very early intensive SLT with the Language Enrichment Therapy program over 21 days had no effect on the degree of aphasia in unselected acute aphasic stroke patients. In aphasic patients with more fluency, SLT resulted in a significant improvement as compared to controls. A higher educational level of >12 years was beneficial.

Background and Purpose: Pharmacotherapy aimed at stroke rehabilitation through direct central nervous effects may be assumed to work in a similar way for language recovery and sensory-motor recovery. Some data suggest that antidepressant drugs could be beneficial also for functional improvement. This prompted us to investigate whether regression from aphasia after acute stroke could be enhanced by antidepressive drug therapy. Methods: We randomised 90 acute stroke patients with aphasia to either 600 mg moclobemide or placebo daily for 6 months, within 3 weeks of the onset of stroke. Aphasia was assessed prior to treatment and at 6 months, using Reinvang’s ‘Grunntest for afasi’ and the Amsterdam-Nijmegen-Everyday-Language-Test (ANELT). Result: The degree of aphasia decreased significantly at 6 months, with no difference between the moclobemide- and the placebo-treated groups. Multivariate regression analysis including treatment group, activities of daily living, aetiology of stroke, ANELT, and Reinvang’s coefficient at baseline, and neurological deficit confirmed these results. In all, 13 in the moclobemide and 10 in the placebo group stopped taking the study medication. No further change was found in the 56 aphasic patients followed up for another 6 months with no medication. Conclusions: Compared to placebo, treatment with moclobemide for 6 months did not enhance the regression of aphasia following an acute stroke.

The 2 tests show a close and consistent correlation over time and are equally sensitive to improvement. They have a similar capacity to predict complete recovery. A standardized test appears to be more suitable for patients with aphasia in the acute stage, while a functional test is more suitable in the subacute/chronic stage.

It is feasible to conduct a randomized controlled study on very early SLT for acute aphasic patients.
