Whether confusion can be recovered after a brain hemorrhage depends on the size and location of the brain hemorrhage. If it is a small amount of brain hemorrhage, the bleeding is only a few milliliters, the impact on limbs and intelligence will not be very big. If it is a moderate to large amount of brain hemorrhage, which is dominated by hemorrhage in the frontal temporal lobe, the patient will have lower intelligence, and his memory and comprehension will be a bit poorer. There will also be uncontrolled mental activities. As to when the patient can return to normal, it depends on the absorption of hematoma, after about 3 months or 6 months of treatment and exercise, the memory and comprehension will be better than the early stage, but it is more difficult to return to the normal level. Therefore, the recovery of confusion and comprehension after cerebral hemorrhage should be decided according to the size and location of the hemorrhage.
