The ‘Standard’ for Poststroke Aphasia Recovery

Long-term prognosis of aphasia after stroke

“…Future studies will help to further improve the estimation, but no prognostic study will ever be able to provide a prediction model with 100% certain predictions. Other differences with our study are that the authors1 used 3 months as the principle endpoint and excluded patients with severe aphasia 21…”

Factors predicting post-stroke aphasia recovery

“…A study by Mimura et al (1998) noted that an early recovery of left hemisphere CBF correlated with lessened initial impairment of language and better recovery within a year. In summary, a continuing hemisphere hypoperfusion and the delay in return of normal CBF and cerebral metabolic rate (CMR) adjacent to lesions during the early post-stroke period leads to poorer long-term recovery (Hillis 2010) [See Table 1 for summary] Naeser et al (1989Naeser et al ( , 1998 Speech comprehension has better recovery compared to expression Mazzoni et al (1992) Transcortical sensory aphasics have a worse prognosis than Broca's or transcortical motor aphasics Basso et al (1979) Phonology improves earlier than semantic or syntactic language.…”

The Factors Associated with Good Responses to Speech Therapy Combined with Transcranial Direct Current Stimulation in Post-stroke Aphasic Patients

“…Previous studies reported that prognosis is not better for non-fluent aphasia compared to fluent aphasia,13 and predictability is less but the degree of improvement changed by the severity of stroke or aphasia 14-16. According to studies in 2010, language dysfunctions after stroke seem to show highly predictable recovery which is related to initial impairments and 70% of patients recovered during the first 90 days 11,17…”
