Stroke is a neurological deficit caused by a brain injury secondary to a vascular mechanism. It can be classified as: ischemic or hemorrhagic. Ischemic form is more common, resulting from insufficient cerebral blood supply. Most patients who suffer strokes have associated diseases such as diabetes, hypertension, dyslipidemia or cardiovascular disease. In the absence of these comorbidities, however, especially in patients younger than 45 years, it should be checked for possible deficiencies of natural anticoagulants such as protein C and protein S. Stroke associated with protein S deficiency is rare, although it is more common in young adults. This clinical report, in turn, aims to describe a case of ischemic stroke associated with reduced protein S in a young patient.
