Patients with brain hemorrhage are not sleepy, but the symptoms produced by the form of diseased tissue in the skull are the expression of wanting to sleep, called narcolepsy. Changes in consciousness, pupil size, blood pressure, and respiration need to be strictly noted . Narcolepsy means that the patient can be woken up and can answer the relevant questions correctly after waking up, such as “what is your name”, “where are you” and so on, but once he does not communicate with him or give him stimulation, he will immediately go to sleep. Reasons: First, mainly because of brain hemorrhage, the cranial brain is strained, nerve damage, especially for the nerve damage under the dominant waking activity, such as the thalamus or brainstem damage, more will appear sleepy performance. Second, inflammatory stimulation, because after brain hemorrhage will release inflammatory stimulation, which leads to drowsiness, as long as the patient can wake up and can answer questions normally, you can let it continue to ensure sufficient sleep, but also to give it sufficient rest time.
