1.Headache This is one of the most common symptoms in neurosurgery. In fact, most of the headaches in daily life are functional and there is no organic brain lesion. (1) Acute headache: The patient usually has no headache symptoms, but suddenly appears severe headache or even vomiting, which can be seen in intracranial hemorrhage, acute inflammation, tumor stroke, etc.; (2) Recurrent paroxysmal headache: Mostly seen in vascular headache, epileptic headache, occipital neuralgia or cervical spondylosis, etc.; (3) Gradually aggravated headache: It often indicates that the intracranial pressure gradually increases. If there is a gradual loss of vision when the headache is aggravated, and if the headache is accompanied by jet vomiting, it is a typical “three main signs” of cranial hypertension, mostly due to neurosurgical diseases. Facial pain includes pain in the face, eyes, nose, mouth and teeth. (1) If there is a sudden onset of transient and severe pain on one side of the face, which feels like a knife cut, electric shock, burning or pins and needles, and it is easy to appear suddenly when washing the face, brushing teeth, eating or talking, the possibility of trigeminal neuralgia should be considered. It is especially important to point out that trigeminal neuralgia sometimes manifests itself as unbearable toothache. Patients often go to dentistry first and impatiently ask for tooth extraction, and as a result, half of the big teeth are often extracted and the pain is still not relieved in the slightest before they finally go to neurosurgery. (2) If there is persistent vague, dull or swelling pain in the face without obvious intervals, the lesion around the trigeminal nerve should be considered and the patient should go to neurosurgery. (3) If there is transient severe pain at the root of the tongue, deep in the oral cavity, or deep in the external auditory canal, and the pain is often induced when swallowing, then it may be hyo-pharyngeal neuralgia, and a neurosurgical consultation should also be made promptly. 3. Involuntary movements (1) Twitching: Involuntary twitching of the limbs, face or chest and abdominal muscles that occurs and stops suddenly. (2) Tremor palsy: involuntary rhythmic shaking of a part of the body or the whole body, accompanied by muscle stiffness and bradykinesia.
