Patients with cerebral infarction in some specific areas may experience fear of heat, such as patients with brainstem and thalamic infarction death, where the infarct lesions can disrupt the central nervous system, thus affecting the thermoregulatory center and causing the patient to experience heat and cold dysregulation. These patients may feel hot and restless, or they may feel cold. In addition, some patients with vascular dementia and post-stroke affective disorders may also have a fear of heat. These patients mainly suffer from autonomic dysfunction. They may have symptoms such as fever, night sweats, irritability, sleep disturbance, anxiety, depression, etc. The symptoms can often be effectively controlled by regulating the plant nervous system and anti-anxiety and depression treatment. Therefore, the symptoms of fear of heat are more common in patients with cerebral infarction, and specific measures can be taken according to different situations.
