    AbstractPatient 1 (82 years old) had recurrent weakness and numbness in the left upper extremity, Patient 2 (71 years old) had transient dysarthria, and Patient 3 (70 years old) had transient apraxia of speech. Transient ischemic attack (TIA) was suspected; however, all three women had a history of head trauma before the symptom onset, and magnetic resonance imaging revealed subdural hematomas near the responsible lesions associated with sulcal hyperintensity (SHI) in the cerebral sulcus near the hematoma. Patients 1 and 2 improved spontaneously, whereas Patient 3 improved with antiseizure medication. Subdural hematomas associated with SHI may have transient focal neurological deficits that manifest through a mechanism unlike TIA.
