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.
