- Clinical observation suggested to us that aphasia recovers relatively better than other deficits early after intravenous recombinant tissue plasminogen activator (IV-rtPA) treatment in stroke patients with minor deficits, while the reverse seemed the case in those with severe deficits. Retrospective analysis of acute ischemic stroke patients with aphasia admitted within 3hours from symptom onset and treated with IV-rtPA was carried out. Stroke severity, aphasia and global neurological impairment were assessed at admission and 24hours after thrombolysis. Improvement of aphasia (gain of ⩾1 point on the National Institutes of Health Stroke Scale [NIHSS] aphasia score) and global neurological improvement (gain of ⩾4 points on the NIHSS) were compared in minor strokes (NIHSS ⩽7), moderate strokes (NIHSS 8-15), and major strokes (NIH ⩾16). Sixty-nine of 243 stroke patients suffered from aphasia. Improvement of aphasia occurred in 7/16 minor strokes, 11/25 moderate strokes, and 7/28 severe strokes. Improvement of ⩾4 points on the NIHSS occurred in 3/16 minor strokes, 17/25 moderate strokes and 15/28 severe strokes. There is a significant (X(2)=4.073, p<0.05) dissociation of recovery of aphasia and that of other neurological deficits between minor versus severe strokes. This confirms the clinically suspected dissociation between a good early recovery from aphasia in minor strokes relative to recovery of other neurological deficits, as opposed to a better recovery from other neurological deficits than from aphasia in patients with severe strokes.

- OBJECTIVE: Stroke patients with aphasia have a high long-term morbidity. Intravenous rt-PA (iv) thrombolysis is given more deliberately to these patients. Early outcome data is lacking. Aim of this study was to determine early benefit from rt-PA in patients with aphasia. METHODS: Data of stroke patients treated by iv thrombolysis was scrutinized for the presence of aphasia defined as ≥1 point for aphasia on the National Institute of Health Stroke Scale (NIHSS). Improvement was defined as a gain of ≥1 point within 24h. Cranial computed tomography (CT) scans were evaluated regarding early ischemic changes (EICs), infarct volume and localization. RESULTS: Fifty patients with aphasia were included. 16 (32%) of patients improved (4 (36%) minor, 7 (41%) moderate, 5 (23%) major stroke patients), while 44 (62%) remained unchanged. Of 28 patients with EICs, 10 (36%) improved compared to 7 out of 22 (32%) patients without (p=0.773). Aphasia outcome was significantly associated with infarct volume at admission and at 24h (Kruskal-Wallis, p=0.033, p≤0.001, respectively). CONCLUSION: EICs are not predictive of aphasia outcome and patients with improvement showed smaller infarct volumes. One third improved within 24h, while two thirds remained unchanged. This might justify a closer follow-up of aphasia in stroke patients at the acute stage.
