Whether or not you will be awake after the cerebral edema disappears after a cerebral hemorrhage is not absolute; if the cerebral edema is small, you will usually be awake. If the cerebral edema is more extensive or if there is edema in the brain stem or other areas, the patient may not be awake even after the edema disappears. Cerebral edema indicates that the patient may experience headache, vomiting, and coma. If the cerebral edema is small, it usually disappears after treatment with medications such as mannitol and furosemide as prescribed by the doctor. After the cerebral edema disappears, the patient can usually wake up. If the cerebral edema is large and causes severe compression of the patient’s cerebral cortex, resulting in irreversible damage to the cerebral cortex, the patient may not be able to wake up even if the cerebral edema subsides after surgery. In addition, if the cerebral edema occurs in the brainstem, resulting in irreversible damage to the nerve conduction bundles of the brainstem, the patient may not be able to wake up even after the cerebral edema disappears. It is recommended that patients with cerebral edema symptoms should be treated as soon as possible to avoid delaying the condition.
