Right-Hemisphere Stroke and the Limits of a Purely Linguistic Assessment
A 61-year-old woman is 3 weeks after a right-hemisphere stroke. Her language scores on a standard aphasia battery are within normal limits: she names, repeats, and comprehends single words and sentences well. However, her husband reports she 'misses the joke', talks too much and too close to people, and interrupts. She has left-sided neglect on cancellation tasks, bumps into doorframes on the left, and has difficulty planning a simple meal. She wants to return to her job as a primary-school teacher. The team asks whether she needs speech therapy at all, since her 'language is normal'.
1. Why is a normal aphasia battery insufficient here, and what communication deficits should be assessed?
Read the worked answer
Standard aphasia batteries test linguistic form (phonology, semantics, syntax) and can be normal in right-hemisphere damage. The relevant deficits are in pragmatics and cognitive-communication:
- Discourse and topic management - over-talking, interrupting, poor turn-taking.
- Inference, humor, and non-literal language - 'missing the joke'.
- Prosody and emotional communication - flat or inappropriate affect in speech.
- Social appropriateness and awareness of others' perspective.
- Attention, neglect, and executive function - left neglect, bumping into things, difficulty planning a meal - which affect communication in real settings.
These are exactly the skills a teacher needs. A 'normal' aphasia score says nothing about classroom communication, so the answer to the team is: yes, she needs cognitive-communication assessment and intervention.
2. What assessment methods and return-to-work plan would you propose?
Read the worked answer
Assessment:
- Discourse-level tasks: picture description, retelling, and a short conversation analyzed for topic maintenance, turn-taking, and informativeness.
- Pragmatic and social-cognition tasks: inference from short stories, humor, and interpreting tone.
- Executive and attentional measures and neglect assessment relevant to classroom demands.
- Ecological observation: a simulated or real classroom task (e.g., explaining a simple lesson) with feedback.
- Input from her husband and, with consent, colleagues about real-world communication.
Return-to-work plan:
- Staged return: start with non-teaching duties, then small-group teaching, then full class, with review points.
- Strategy training: self-monitoring cues for turn-taking and volume, 'pause and check' routines, and written planning supports.
- Environmental supports: seating, visual aids, and a co-teacher during transition.
- Measure outcomes in the classroom, not only on tests.
Frame the plan around her goal (returning to teaching) so the team sees the purpose of therapy.
