What are the symptoms of concussion?

After a blow to the head, you will feel a temporary loss of consciousness and everything seems to go black in front of your eyes. Some people fear that this is a concussion. Everyone should know that concussion actually refers to a temporary dysfunction of the central nervous system, and there are many symptoms of concussion. Some people do not suffer any serious conditions for the time being after a head hit, but they are likely to have some sequelae in the future.

In order to help everyone understand the symptoms of concussion, here we introduce some symptoms of concussion. I hope you can understand more after reading this. There are four manifestations of concussion, which can be seen in the following aspects.

1. Transient brainstem symptoms: Impairment of consciousness occurs immediately after trauma to the head, manifested as confusion or complete coma, lasting for several seconds, minutes or tens of minutes, but generally not more than half an hour. The patient may also experience symptoms such as pale complexion, sweating, decreased blood pressure, slow heartbeat, shallow and slow breathing, decreased muscle tone, and slow or absent various physiological reflexes. In most patients with reversible mild concussion, the central nervous system function recovers rapidly from bottom to top, from the cervical spinal cord-medulla oblongata-brainstem to the cerebral cortex; while in irreversible severe concussion, it may be a top-down inhibition process, which interrupts the function of the medullary respiratory center and circulatory center for too long, thus leading to death.

2. Retrograde amnesia (recent amnesia): After the patient regains consciousness, he cannot recall the situation at the time of injury or even a period of time before the injury. The more severe the concussion and the longer the primary coma, the more obvious the recent amnesia is, but he can recall past events (remote memory). This may be related to damage to the hippocampus.

3. No positive signs were found in neurological examination.

4. Patients in the recovery period of concussion often have symptoms such as dizziness, headache, nausea, vomiting, tinnitus, insomnia, etc., which usually disappear gradually within weeks to months. However, some patients have long-term symptoms such as dizziness, headache, insomnia, irritability, inattention and memory loss. Some of them are recovery symptoms. If there is no obvious improvement after 3 to 6 months, in addition to considering whether there are mental factors, detailed examination and analysis should be carried out to see if there is any delayed damage. Do not use the term "sequelae of concussion" to sum it up, which will increase the mental burden of the patient.

What are the symptoms of concussion? These four conditions are specific manifestations of concussion. If you find yourself with a concussion, you must not ignore it, because if it is not treated, it is likely to cause other more serious effects, causing great harm to your life and psychology. Therefore, in order to live a happy life in the future, you still need to do a good job of disease prevention and examination.
