Description: This is a review of studies which provide outcomes of aphasia treatment with a specified time post-onset, in order to determine if there is a relationship between treatment response and time post-onset.

Question(s) Addressed:

Is there a relationship between time post-onset of aphasia and response to treatment for aphasia in chronic patients one year or longer after symptom onset?

Population: Patients one year or longer after onset of aphasia symptoms

Intervention/Assessment: Treatment for aphasia

Number of Studies Included: 23

Years Included: 1985 - 2003



  • Treatment
    • Language
      • General Findings - Generally, individuals benefit positively from aphasia treatment regardless of time post-onset. "Therefore, expectations of how well individuals will respond to aphasia treatment, which are based solely on time postonset, are not warranted" (p. 3051).
