Cerebral infarction patients lifting up the quilt all the time may be related to environmental factors, or it may be caused by motor aphasia, mental behavioral abnormality and so on. 1. Environmental factors: If the weather is too hot in the near future, the indoor temperature is high, and the bedding given by the family members to the patients with cerebral infarction is relatively thick, which leads to the patients feeling hot and uncomfortable, and they will lift up the quilts all the time in order to dissipate the heat and alleviate the uncomfortable symptoms. 2. Motor aphasia: some patients with cerebral infarction have motor aphasia due to the damage of the speech center, resulting in the inability of patients to express their thoughts through language. When they are hot or cold, or after urinating or defecating, they may lift up the quilt to attract the attention of their family members. 3. Abnormal mental behavior: Some patients with cerebral infarction have damage to the frontal lobe and temporal lobe, which may cause mental symptoms, which may be manifested as restlessness and agitation, and the phenomenon of lifting up the quilt may occur, and they may also shout frequently, and so on. Patients with cerebral infarction lifting the quilt all the time may also be caused by other reasons, and they should go to the hospital in time to find out the triggers and help the patients to solve the problems.
