Obstructive sleep apnoea (OSA) is never considered the aetiology of focal neurological symptoms or in the differential of stroke-like symptoms. Although it is a risk factor for stroke and can produce global neurological symptoms, such as confusion and decreased consciousness, it has never been reported to produce focal neurology. This case describes a patient with OSA, diagnosed through polysomnography, who had multiple presentations of focal stroke-like symptoms and signs, despite initial optimal post-stroke management. Symptomatic cessation was only achieved after the patient received continuous positive airway pressure therapy.
