Transient Stuttering as a Sole Presentation in a Patient With a Subcentimeter Left Frontal Cortical Ischemic Infarct.

Abstract

Stuttering is a complex speech disorder that is associated with a variety of etiologies, including psychological factors, metabolic disorders, and structural abnormalities. While stuttering is typically not caused by stroke, it is important to include it in the diagnostic evaluation, especially in patients with a history of neurological conditions. Of the clinical presentations of stroke-induced stuttering, transient stuttering following stroke has seldom been documented, as most patients who develop a stutter following a stroke end up developing permanent speech deficits. Additionally, as most cases of stroke-induced stuttering are part of a broader neurological presentation, stuttering generally does not present as an isolated symptom. Furthermore, although strokes of various sizes have been implicated in stuttering, it is quite uncommon for the affected lesion to be smaller than 1 cm. We present a rare case of transient, isolated stuttering following a subcentimeter stroke and a subsequent review of relevant literature. Our case report highlights the diversity of stroke-related speech disorders and the importance of considering even minor strokes in the differential diagnosis of stuttering.
