Conclusions Piracetam plays a limited role in the rehabilitation of overall language impairment and only benefits written language ability at the end of trials .
Its effect on overall linguistic level and written language tends to emerge within a short period and declines thereafter
Background Aphasia is a common symptom in post-stroke patients .
Piracetam is a commonly used nootropic agent that promises various benefits to brain function , including language improvement .
Objective We performed a systematic review and meta- analysis to assess whether piracetam facilitates the rehabilitation of language performance in post-stroke patients .
Aphasia in acute stroke: Incidence, determinants, and recovery
Knowledge of the frequency and remission of aphasia is essential for the rehabilitation of stroke patients and provides insight into the brain organization of language . We studied prospect ively and consecutively an unselected and community‐based sample of 881 patients with acute stroke .  Assessment of aphasia  was done at admission , weekly during the hospital stay , and at a 6‐months follow‐up using the aphasia score of the Sc and inavian Stroke Scale .  Thirty‐eight percent had aphasia at the time of admission ; at discharge 18 % had aphasia .  Sex was not a determinant of aphasia in stroke , and no sex difference in the anterior‐posterior distribution of lesions was found . The remission curve was steep : Stationary language function in 95 % was reached within 2 weeks in those with initial mild aphasia , within 6 weeks in those with moderate , and within 10 weeks in those with severe aphasia . A valid prognosis of aphasia could be made within 1 to 4 weeks after the stroke depending on the initial severity of aphasia . Initial severity of aphasia was the only clinical ly relevant predictor of aphasia outcome . Sex , h and edness , and side of stroke lesion were not independent outcome predictors , and the influence of age was minimal
