A mild concussion primarily refers to a patient experiencing a brief loss of consciousness, generally lasting a few seconds to several minutes. Another symptom that can occur is retrograde amnesia, where the patient is unable to recall details of the incident that caused the injury. Some patients may also experience a drop in blood pressure and appear pale. Additionally, patients may suffer from headaches, dizziness, nausea, loss of appetite, insomnia, tinnitus, decreased memory, and lack of concentration, among other clinical manifestations. Mild concussions typically recover after five to seven days of rest, or symptomatic treatment, with most patients regaining their health.

How to treat a concussion

The management of concussion patients includes general management and symptomatic drug treatment. General management should include psychological communication with patients who may feel fear and anxiety. Keeping the patient's mood relaxed is beneficial to the recovery of the disease. Secondly, in the early stages of concussion, it is important to observe changes in the patient's general condition to prevent the possibility of delayed intracranial hemorrhage. Thirdly, the patient's diet should be light, easy to digest, and nutritionally reasonable. Additionally, there is symptomatic drug treatment. Some patients may experience severe headaches and insomnia. We can administer some analgesic and hypnotic medications orally. Treatment can also include oral medications that promote the recovery of nerve cells.

What are the symptoms of a concussion?

Patients with concussions often present with a clear history of head trauma, followed by a brief period of impaired consciousness, often referred to as a state of drowsiness or stupor. As the condition progresses, patients usually regain consciousness spontaneously and experience significant symptoms such as headache, dizziness, nausea, and vomiting. In addition, during subsequent treatment, patients may experience clinical symptoms such as insomnia at night, frequent dreaming, and easy waking. Patients often cannot accurately recall the incident at the time of injury, a condition clinically known as retrograde amnesia. However, in such patients, head CT or MRI scans typically show no significant positive findings. For these patients, diagnosis is generally made based on clinical presentation.

How to check for a concussion?

How is a concussion diagnosed? In fact, the diagnosis of a concussion is primarily based on clinical manifestations such as a clear history of head trauma, temporary confusion, and retrograde amnesia. Concussions can also undergo some routine examinations, such as CT scans of the head, X-rays of the head, electroencephalography, cerebral blood flow imaging, and cerebrospinal fluid analysis. However, these test results are usually negative, meaning that the diagnosis of a concussion mainly relies on clinical manifestations and there are no effective diagnostic tests.

How long should one rest for a concussion?

Concussions generally require about one to two weeks of rest, depending mainly on the specific symptoms of the patient. If the symptoms are relatively mild and the injury was not particularly severe, then about a week of rest is usually sufficient for returning to normal work and study. In some cases, if the concussion was relatively severe at the time of injury and subsequent complications or sequelae occur, then the rest period may need to be appropriately extended, possibly to about a month, depending on the patient's specific symptoms. In the vast majority of cases, resting for two weeks is generally sufficient for returning to normal work and study without involving any special issues. As long as medical advice is followed and treatment is correctly administered, many concussions can heal completely.
