The reason why the brain is sweating after infarction is mainly analyzed from the following aspects: First, according to the infarction site, such as the infarction of the frontal lobe and the base of the frontal lobe, it is easy to have high fever and sweating especially after infarction, which may be related to the damage of the contact fibers between the base of the frontal lobe and thalamus. Secondly, after thalamic infarction, it will cause symptoms of autonomic impairment and sweating, especially local sweating, and if the thermoregulatory center is damaged, high fever with body sweating may occur. Thirdly, after cerebral infarction, patients combined with poor cardiac function, in the acute phase of heart failure, some patients will also appear sweating, sweating is mainly based on eating or a lot of rehydration, especially obvious at night.
