Cerebral infarction is a kind of infarction disease that occurs in the brain. After the occurrence of the disease, the blood circulation in the brain of the patient is affected, and then ischemia and hypoxia occur, which can lead to death in severe cases. In severe cases, it can lead to death. After the onset of the disease, the patient may have symptoms of mania. Generally, because of the tissue necrosis and edema caused by cerebral infarction, there is an increase in intracranial pressure and cause mania, most of this situation is the most serious for 3-5 days, and then will gradually improve, but there are individual differences. However, the duration of mania in patients with cerebral infarction also depends on the location of the infarction, such as frontal lobe infarction and temporal lobe infarction, which will easily cause patients to have symptoms of agitation and restlessness, and the duration of this condition may be longer, and it may exist in the acute stage until it has improved in about 1 month. The patient needs to actively undergo subsequent rehabilitation exercises, which may allow the manic symptoms to gradually decrease. In addition, some psychotropic medications can be supplemented for treatment to improve the symptoms. In addition, if the patient has some complications after cerebral infarction, such as lung infection, urinary tract infection, bedsores, etc., or taking some nutritive drugs or antibiotics, the patient may also have irritability symptoms, and at this time, the patient needs to eliminate the causative factors under the guidance of professional doctors. Usually when the triggers are reduced or disappeared, the symptoms of restlessness will be gradually relieved, and the specific duration usually depends on the elimination time of the triggers.
