Patients with cerebral infarction keep trying to sleep for some of the following reasons: 1. Inhibition of the cerebral cortex. If the cortical branch of the arterial vessels is diseased, it can lead to infarction of the cerebral cortex. The cortical lesion can cause the sleep-wake cycle to be disrupted, and the patient is in a drowsy state most of the time and only occasionally in an awake state. 2. Brainstem infarction. Brainstem infarction can cause damage to the brainstem reticular upstream activation system, resulting in a prolonged state of lethargy. 3. Post-stroke affective disorder. Some patients with cerebral infarction develop anxiety and depression, and patients are silent and lethargic throughout the day. These patients with cerebral infarction combined with drowsiness should be treated with behavioral modifications as well as medication. Patients can be encouraged to listen to more music and radio and to get out of bed more often for activities. At the same time, Chinese patent medicines such as Waking Brain Jing and Brain Heart Tong, Nourishing Blood and Clearing Brain Granules can be given to wake up the brain and open the mind.
