Transient speech impairment: a minor stroke/TIA case escaping conventional imaging methods

This case report discusses the diagnostic challenges posed by transient ischaemic attacks (TIAs) and minor strokes presenting with atypical symptoms, focusing on a 62-year-old male presenting with isolated speech difficulties reminiscent of Broca's aphasia. Despite initial inconclusive imaging, subsequent evaluation revealed minor periventricular changes consistent with ischaemic small vessel disease and a pre-existing lacunar infarct. The resolution of symptoms within 10 days highlights the transient nature of the event. The case underscores the importance of recognising nuanced presentations of cerebrovascular events and the necessity for standardised diagnostic criteria and assessment tools for transient speech impairments resembling Broca's aphasia. Further research into the mechanisms underlying these transient events, utilising advanced imaging techniques, such as diffusion-weighted MRI (DWI), may be warranted to facilitate early recognition and appropriate management in clinical practice.
