Temper tantrums and hitting after brain hemorrhage may be related to the location of the brain hemorrhage, or it may be caused by psychological stress disorder, hyperthyroidism and other reasons. 1. The location of brain hemorrhage: if the brain hemorrhage is located in the frontal lobe or temporal lobe, as these parts of the brain dominate and control people’s emotions, when brain hemorrhage occurs in these parts of the brain, resulting in damage to the brain nerves, it may cause abnormal mental symptoms, which may lead to temper tantrums and hitting. 2. Psychological stress disorder: After cerebral hemorrhage, patients often suffer from a series of sequelae, such as adverse speech, dysphagia, paralysis of limbs, etc. The sudden sequelae of cerebral hemorrhage are difficult for patients to accept for a while, which leads to post-stroke psychological disorders, and the phenomenon of temper tantrum and hitting may occur. 3. Hyperthyroidism: If the patient has hyperthyroidism before the cerebral hemorrhage, and the patient does not take medication regularly after the cerebral hemorrhage, which leads to excessive secretion of thyroid hormones, the patient may show the phenomenon of grumpy hitting. The temper tantrum after brain hemorrhage may also be caused by other reasons, and it is recommended to consult a doctor in time.
