Can CT scans show mild concussion?

Concussion is a relatively common disease, which is mainly caused by a severe blow to the brain. At this time, you should go to the hospital for examination in time. CT examination is also a common method, but in general, the effect of CT examination is not particularly good. You can perform skull X-ray examination, EEG examination, cerebral blood flow examination, etc. Let us learn about it.

Lumbar puncture showed normal intracranial pressure, and some patients had decreased intracranial pressure. The cerebrospinal fluid is colorless and transparent, does not contain blood, and the white blood cell count is normal. Biochemical tests are mostly within the normal range, and some may reveal a significant increase in acetylcholine content, a decrease in cholesterase activity, and an increase in potassium ion concentration. 1. No fracture was found in skull X-ray examination. 2. Brain CT scan showed no obvious abnormal changes in the skull and brain. 3. Electroencephalogram examination: The electroencephalogram (EEG) is usually normal several months after the injury. 4. Cerebral blood flow examination: Cerebral blood flow may be reduced in the early stage after injury.

diagnosis

1. A transient coma occurs immediately after a head injury, lasting within 30 minutes. After waking up, the patient often has symptoms such as recent amnesia, headache, dizziness, nausea, anorexia, vomiting, tinnitus, and inattention. Blood pressure, respiration, and pulse are basically normal. 2. Neurological examination showed no positive signs, and lumbar puncture showed normal cerebrospinal fluid pressure and composition.

treat

The patient can be observed in the emergency room for a certain period of time after the injury, and close attention should be paid to changes in consciousness, pupils, limb movements and vital signs. If secondary intracranial lesions or other complications are found, timely diagnosis and treatment can be provided. Patients in the acute stage of concussion should pay attention to bed rest, avoid adverse external stimulation, reduce mental activity, and appropriately give sedatives and drugs to improve autonomic nervous function, and pay attention to the patient's psychological adjustment and treatment.
