突发头痛伴精神异常，警惕脑卒中！

One day ago, the patient developed a headache after getting cold, characterized by persistent bilateral temporal throbbing pain, accompanied by neck stiffness and fatigue. There was no abnormal mental behavior. The patient thought they had caught a cold and took 'antiviral granules', but there was no relief. Half a day ago, the patient exhibited abnormal mental behavior, such as forgetting to turn off the faucet and mistaking zebra crossings. They also experienced weakness and intermittent numbness in the left hand, resulting in dropping objects. After taking 'compound cold tablets', the symptoms did not improve. Therefore, the patient was admitted to the neurology department of our hospital through the emergency department.
