Introduction
After a fall, if the amount of intracranial hemorrhage is small, the patient may regain consciousness within one to two days following hematoma removal. If there is extensive brain bleeding and herniation has occurred before surgery, it may take one to two weeks or even longer to regain consciousness. If the bleeding occurs in a critical area of the brain, it may take approximately two to three months to awaken, or the patient may remain in a prolonged coma with vegetative state.

The time it takes for a patient to regain consciousness after surgery for brain hemorrhage due to a fall generally depends on the severity of the condition.

If the amount of bleeding is relatively small, patients may gradually regain consciousness within one to two days after timely medical treatment and hematoma removal. However, if the patient experienced extensive brain hemorrhage and had already developed brain herniation before surgery, recovery usually takes longer—possibly one to two weeks or even more. Additionally, if brain herniation occurred prior to surgery and the bleeding is located in critical areas such as the brainstem, the time to regain consciousness may be significantly prolonged, often requiring 2–3 months. In some cases, a small number of patients may never regain consciousness and remain in a prolonged vegetative state.

For patients who remain unconscious for more than two weeks after a fall-related brain hemorrhage, rehabilitation measures such as hyperbaric oxygen therapy may be considered under medical guidance, which could help gradually restore consciousness in some individuals.
