Concussion diagnosis usually includes, first, a history of head trauma; second, after a head CT scan, no significant substantive changes are observed, but the patient has experienced a transient loss of consciousness, typically not exceeding half an hour. Third, there is approximated amnesia where the patient cannot recall the incident. Some may show symptoms such as decreased blood pressure and pale complexion, while others can experience dizziness, headache, nausea, loss of appetite, insomnia, memory deterioration, and lack of concentration among a series of clinical presentations. Diagnosis of concussion can be confirmed through medical history, supplementary examinations, and clinical symptoms.

How to administer first aid for a concussion

After a concussion occurs, the injured should be quickly moved from a dangerous environment to a safe area. The injured person should lie flat and rest quietly without sitting up or standing. The head can be appropriately cooled, and it is important to keep the body warm. For patients who are unconscious, it is necessary to keep the airway clear and closely observe their consciousness and pupils. If there are airway secretions or vomiting, they should be cleaned up promptly. If the patient has already experienced respiratory or circulatory problems, immediate cardiopulmonary resuscitation should be performed. After the aforementioned emergency treatment, the next step is to transport the patient to a nearby well-equipped hospital for further diagnosis and treatment.

Is a concussion dangerous?

Concussion is not a severe brain injury and there is no need for excessive worry; symptomatic supportive treatment is usually sufficient. Typically, rest is advised, along with a light diet, regular living habits, and abstaining from smoking and alcohol. If necessary, treatment may include neuro-nutritive medications and drugs to improve microcirculation. Generally, symptoms should subside within one to two weeks. It is important to note that concussions occur after head trauma, and there is a certain likelihood of re-bleeding within the first three days following the trauma. After three days, the possibility of intracranial hemorrhage becomes very very low. Therefore, post-concussion there is still some risk, and it is necessary to closely monitor any changes in the condition, potentially requiring hospitalization for observation and treatment.

Is a concussion scary?

Firstly, a concussion is the mildest form of brain injury, mainly characterized by transient consciousness disturbances, generally not lasting more than half an hour. The second characteristic is recent memory loss, with an inability to recall the circumstances of the injury. At the time of the injury, one may also experience pale complexion, blood pressure drop, and pupil constriction. After the injury, some patients may suffer from dizziness, headache, nausea, loss of appetite, tinnitus, lack of concentration, and memory decline, among other clinical symptoms. Patients with a concussion generally recover after 1-2 weeks of systematic treatment, and the majority of concussions are recoverable, so they are not as fearsome as believed.

How to diagnose a concussion?

Concussion typically involves functional impairment of brain activities. His head CT showed no organic damage. The main clinical symptoms include transient consciousness disturbances and recent memory loss after the injury. Some patients may experience significant symptoms such as headache, dizziness, nausea, vomiting, and insomnia, among other clinical symptoms. For concussion patients, the first step is to conduct a head CT to rule out intracranial organic injuries, followed by cerebrospinal fluid examination, and then an electroencephalogram test.

Some patients also experience varying degrees of headache, dizziness, nausea, vomiting, blindness, impaired memory, or lack of concentration, among other clinical symptoms.
