Summary
Delayed-onset ipsilateral sensory symptoms after stroke are a newly recognized phenomenon. These mild symptoms occur on the same side as the lesion, mirroring the most severe central poststroke pain.
Area of Science:
- Neurology
- Neuroscience
- Clinical Medicine
Background:
- Central poststroke pain (CPSP) typically manifests as sensory symptoms contralateral to the cerebral lesion.
- The occurrence of ipsilateral sensory symptoms in CPSP has been historically unrecognized.
Observation:
- This study describes 6 patients with unilateral stroke who initially presented with contralateral sensory symptoms.
- These patients later developed delayed-onset, mild ipsilateral sensory symptoms.
- The ipsilateral symptoms mirrored the location of the most severe CPSP and lacked objective sensory deficits.
Findings:
- Delayed-onset ipsilateral sensory symptoms can occur in patients with central poststroke pain.
- These symptoms appear after an initial period of contralateral sensory disturbances.
- The ipsilateral symptoms are mild and localized to body parts mirroring the most painful areas.
Implications:
- This finding expands the understanding of sensory symptom presentation in central poststroke pain.
- It suggests potential novel pathogenic mechanisms for delayed sensory disturbances after stroke.
- Further research is warranted to elucidate the underlying neurological processes and clinical significance.
