Within 12 hours of an intracranial hemorrhage, patients can experience a variety of different symptoms, depending primarily on the size of the bleed and the location of the bleed. In the case of a massive cerebral hemorrhage, the patient may experience headache and dizziness. In severe cases, coma may occur, as well as hemiparesis, or quadriplegia, or bulbar palsy, to name a few. If a brain stem hemorrhage is being considered, the patient may experience, unstable vital signs, including unstable respiration, blood pressure and heart rate, as well as decreased oxygen saturation, among others. If the amount of bleeding is small, the patient mainly shows focal signs and symptoms, and may have hemiparesis, hemianopsia, hemianopsia, and hemiplegia. Speech dysfunction can also be present, mainly seen in left-sided lesions. Patients may also present with dizziness, balance disorders, and ataxia. This is usually due to cerebellar and brainstem hemorrhage, among others.
