There are two main reasons for incontinence after cerebral hemorrhage: First, after cerebral hemorrhage, the neural control of urination and defecation is in a state of imbalance, that is, there is no way to control urination and defecation. The second point is the formation of hydrocephalus in combination. After a brain hemorrhage, if the cerebrospinal fluid circulation pathway is not smooth, it will form hydrocephalus, and once the condition of hydrocephalus is formed, the intracranial pressure increases sharply, which will have a significant impact on the overall brain state, and will also cause the higher nerve centers to be unable to control the same lower nerve centers will appear as long as there is urine will urinate, there will be defecation, thus causing incontinence.
