头痛伴精神行为异常和肢体无力，警惕脑血管意外！

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