Concussion usually manifests as temporary consciousness disorder and immediate amnesia, meaning the inability to recall specific details at the time. Some patients also experience a series of clinical symptoms including headaches, dizziness, nausea, vomiting, insomnia, and memory decline. If a patient with a concussion vomits, the first step should be to conduct a head CT to rule out the possibility of intracranial hemorrhage. In addition, symptomatic treatment can be actively provided, with metoclopramide commonly used for intramuscular injection.

What to check for a concussion?

A head CT scan for concussion usually does not show organic changes, as it primarily stems from temporary dysfunction of brain neurological functions. The main symptoms include brief disturbances in consciousness, retrograde amnesia, and some patients may also experience a series of clinical symptoms such as headaches, dizziness, nausea, and vomiting. For patients with concussion, what we need to do is a head CT scan or an MRI of the head to rule out organic brain lesions. The second option is to examine the cerebrospinal fluid. The third option is to conduct an electroencephalogram (EEG) test.

What is a concussion?

Firstly, a concussion is a relatively mild condition where the brain sustains damage, usually accompanied by disturbances in consciousness, which are temporary, such as unconsciousness lasting no longer than half an hour. The second symptom is akin to amnesia, where the injured person is unable to recall the circumstances of the injury. At the time of the injury, symptoms such as a drop in blood pressure and pale complexion can occur; some patients may also experience dizziness, headache, nausea, loss of appetite, poor sleep, as well as a range of clinical manifestations including lack of concentration and memory decline.

How long does vomiting last with a mild concussion?

Patients with mild concussion typically exhibit brief disturbances in consciousness lasting from several seconds to several minutes after the injury, usually not exceeding half an hour, along with retrograde amnesia. Some patients may also experience varying degrees of headache, dizziness, nausea, vomiting, and other clinical symptoms. The vast majority of mild concussion patients can recover within five to seven days with rest and conditioning, meaning that mild concussion symptoms, including vomiting, can resolve within 5-7 days.

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.
