1.Headache This is one of the most common symptoms of neurosurgery. In fact, most of the headaches in daily life are functional and there is no organic lesion of the nervous system, only the following cases should be promptly seen in neurosurgery: (1) Acute headache: the patient usually has no headache symptoms, but suddenly appears severe headache or even with vomiting, which can be seen in intracranial hemorrhage, acute inflammation, tumor stroke, etc. (2) Recurrent paroxysmal headache: It is usually seen in vascular headache, epileptic headache, occipital neuralgia or cervical spondylosis, etc. (3) Gradually aggravated headache: It often indicates a gradual increase in intracranial pressure. It is mostly caused by neurosurgical diseases. 2. Maxillofacial pain: including 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, electric shock, burning or pins and needles, and it is easy to appear suddenly when washing the face, brushing the teeth, eating or talking, the possibility of trigeminal neuralgia should be considered. In particular, trigeminal neuralgia sometimes manifests 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 a transient severe pain at the root of the tongue, deep in the mouth, or deep in the external auditory canal, and the pain can often be induced when swallowing, then it may be linguopharyngeal neuralgia, which should also be promptly seen by Neurosurgery. Convulsions caused by brain diseases, especially secondary seizures caused by brain tumors, are characterized by sudden, transient and recurrent seizures. It is often manifested as sudden onset of limb convulsions, which may extend to the whole body, and may be accompanied by impaired consciousness or urinary or fecal incontinence, lasting from a few seconds to several minutes each time, with completely normal interictal periods. 4, limb weakness or unstable walking can gradually aggravate or suddenly appear, early manifestation is the inability to hold chopsticks, easy to drop, holding objects difficult, if the lower limb weakness, it is manifested as walking dragging, knee easily soft bending or even fall, the sick side of the shoe sole wear is obviously more serious than the healthy side. If the hand or foot cannot be lifted, or even the consciousness cannot control the movement of the hand and foot, it is the so-called “hemiplegia”. There are superficial and deep sensations in the human body. The superficial senses are pain, heat and cold, light touch and pressure, while the deep senses are the sensation of the position of the limb, vibration and movement when the person is closed. 6, visual field disorders Sudden or gradual decline in vision, reduced range of vision, if no ophthalmologic disease is found in the eye examination or found that the fundus has edema manifestations, should go to neurosurgery, these conditions are often caused by intracranial lesions. 7, endocrine disorders female amenorrhea, lactation, early menopause, infertility; male hypogonadism; rapid growth, acromegaly, that is, thick fingers, toes, nose tip and other parts; centripetal obesity, intractable hypertension, etc.. Neurosurgery should be consulted, and these conditions are often caused by intracranial lesions. 8, aphasia Mainly refers to acquired language dysfunction or loss: that is to say, originally there is no deafness, mute, and only later the problem of language function, mostly due to the left side of the brain higher language center affected by the lesion; can be manifested as the following: (1) motor aphasia: manifested as the ability to hear others, can pronounce words, but can not speak or can only say individual single words, unable to repeat. (2) Perceptual aphasia: It is manifested as understanding the speech of others and oneself, although the pronunciation is normal and the speech is coherent, the words are often wrong and the answer is not what is asked. (3) Naming aphasia: It is manifested as knowing the purpose of an object but being unable to name it. (4) Complete aphasia: Loss of both the ability to express and understand language, neither understanding what is said nor being able to speak out. (5) Dyslexia: Normal vision, formerly literate, but now the ability to read words is lost. (6) Dysgraphia: normal hand movement, but cannot write. What symptoms should be seen in neurosurgery? As the initial symptom of facial muscle spasm is eyelid jumping, which is also known as “left eye jumping for money, right eye jumping for disaster”, it usually does not attract people’s attention, but after a period of time, it develops into facial muscle spasm, which is associated with the corners of the mouth to the neck. Facial muscle spasm can be divided into two types, one is primary facial muscle spasm, and the other is secondary facial muscle spasm.
