Recovery does not stop at six months
The six-month figure describes when spontaneous neurological recovery completes — not when therapy-driven improvement ends. These are two separate processes. Clinical trials consistently show meaningful language gains in chronic aphasia when therapy intensity is sufficient.
- +The NIDCD states that some people continue to improve for years after stroke
- +A 25-year case study in peer-reviewed literature documented continued gains in global aphasia
- +Randomised controlled trials of chronic aphasia therapy show positive treatment effects at every stage tested
- +Intensity (hours per week, trials per session) predicts outcome in chronic aphasia more strongly than time since onset

Why progress is slower in the chronic phase
In the first months after stroke, spontaneous biological processes (resolution of swelling, tissue stabilisation) contribute to improvement alongside therapy. In the chronic phase, all gains are therapy-driven. The brain's neuroplastic capacity is unchanged — the biological boost is gone. This means:
- +Higher repetition counts are needed to produce the same magnitude of change
- +Progress is measured over months, not days or weeks
- +Home practice intensity matters more, not less, than in early recovery
- +Tracking data (accuracy over time) becomes essential to see progress that is too gradual to notice day-to-day

Questions to ask your SLP or insurer
If you have been told that further improvement is unlikely because of time elapsed since stroke, these questions are appropriate to raise:
- +What therapy intensity (hours per week) is being proposed, and how does that compare to the intensity used in trials showing positive outcomes in chronic aphasia?
- +Is structured home practice included in the treatment plan, and will session data be tracked?
- +What specific outcome measures will be used to track progress, and at what intervals will they be administered?
- +What is the criterion for continuing or discontinuing treatment, and how will that decision be made?
- +Are there any clinical trials or intensive aphasia programmes in our area that might be appropriate?

Structuring home practice in the chronic phase
| Component | Recommendation | Why it matters |
|---|
| Daily duration | 20-30 minutes | Sufficient to accumulate 200-300 trials without fatigue |
| Frequency | 5-6 days per week | Consistent daily activation drives synaptic consolidation |
| Exercise selection | SLP-assigned only | Clinician chooses the right difficulty and target type |
| Tracking | Record accuracy every session | Gradual gains are invisible without data |
| Rest | 1-2 days per week | Recovery time is part of neuroplastic consolidation |
| Clinic review | Every 2-4 weeks | Allows difficulty adjustment before progress stalls |

Signs that the programme is working
- +Accuracy on target items increases by 10% or more over 4 weeks
- +Retrieval speed (latency) decreases even when accuracy is stable
- +Generalisation to untreated items (words not in the practice set)
- +Reduced reliance on high-level cues over time
- +Self-reports of improved communication in daily conversations

When to reassess
If accuracy on target items has not improved after 6 weeks of consistent high-intensity practice, discuss the following with your SLP:
- +Is the current exercise targeting the right level of the deficit (semantic vs. phonological)?
- +Is the difficulty level appropriate — not too easy, not too hard?
- +Are there medical factors (fatigue, medication changes, mood) affecting performance?
- +Would a different exercise type or modality (e.g., written naming instead of spoken naming) produce better results?
