When a patient with traumatic brain injury recovers from acute trauma, dizziness, headache and various degrees of vegetative dysfunction or psychotic symptoms persist for more than 3 months after the injury without improvement, with no exact positive signs on neurological examination and no abnormal findings on CT, MRI, etc., it is called post-traumatic brain injury syndrome. It is also called post-traumatic brain injury syndrome, post-concussion syndrome, post-traumatic brain injury neurosis, post-traumatic brain injury neurological weakness or post-traumatic brain injury neurosis. The onset of the disease may be caused by the premise of mild organic brain damage, coupled with physical and psychological factors and social factors contributing to the patient. There is no corresponding relationship between the occurrence of post-traumatic brain injury syndrome and the severity of brain tissue damage. Clinical manifestations The post-traumatic brain injury syndrome is characterized by headache, dizziness and neurological dysfunction. Patients often experience head swelling, cutting or throbbing pains of variable duration, which may be exacerbated by insomnia, fatigue, poor mood, poor work performance or external noise. Dizziness is also common. Patients often feel dizzy in the head, lack of clarity in thinking, or a feeling of confusion and disorientation. Patients also often experience emotional instability, easy fatigue, insomnia, poor concentration, memory loss, and even moodiness and agitation. Intermittently or when there is a dysfunction of the vegetative nerves, the patient may experience tinnitus, palpitations, fluctuating blood pressure, excessive sweating, decreased sexual function or menstrual disorders. Diagnostic points 1. History of cranio-cerebral injury, most patients have different degrees of organic brain damage after injury, such as limb paralysis, aphasia, sensory impairment, cranial nerve disorder, psychiatric symptoms and intellectual impairment. After clinical treatment, the signs of neurological damage have disappeared, but the remaining self-conscious symptoms still exist several months or years after the injury. 2.There are functional neurological symptoms, such as headache, dizziness, tinnitus, insomnia and dreaminess, fatigue, memory loss, inattention, emotional instability, etc. There are symptoms of plant nerve dysfunction, such as excessive sweating, palpitations, chest tightness, nausea, poor mood, etc. The above symptoms are often aggravated or relapsed due to mental and physical work or emotional effects. 3. The patient’s complaints are often incompatible with neurological signs. Most of the neurological examinations are normal. 4.Lumbar puncture cerebrospinal fluid pressure is normal. Most of the electroencephalograms are normal, and some patients have mild or moderate abnormalities. 5, attention should be paid to the identification of comorbidities or complications with craniocerebral injury. Treatment 1. Do a good job in explaining patiently and carefully to relieve the patient’s misunderstanding that “concussion sequelae cannot be cured”, make the patient believe that the disease can be cured, and create a good medical living environment for the patient to avoid various adverse stimuli from outside. To relieve the ideological concerns, establish the confidence to overcome the disease and cooperate with clinical treatment. 2, for self-conscious symptoms need to give symptomatic treatment, such as sedative, analgesic, sleeping drugs, nerve cell nutrient applications, as well as glutamate, vitamin B, etc. can be chosen to use. Analgesics can be given for headache, but narcotics or morphine-based drugs should not be used to avoid addiction. Such as rhododendrine (cranial pain), levocetine lidine naproxen, enteric aspirin ibuprofen; dizziness can be given benadryl, trichloro tert-butyl alcohol, etc.; autonomic dysfunction can be given glutamate, iproniazid, γ-aminobutyric acid (γ-aminobutyric acid), methylphenidate (methylphenidate), atropine (atropine sulfate) scopolamine, etc.; excited patients can be given endorphin diazepam (Valium), oxazepam ( Depressed patients can be given glutamate γ-aminotyrosine, etc. 3, conditioning life so that there is regularity. Some patients with a long history of illness, in addition to appropriate rest, can also participate in physical therapy or moderate labor and work to help recovery. 4, with physical therapy, acupuncture, Chinese medicine and other comprehensive treatment can help to improve and recovery.
