Concussions are one of the mildest forms of neurosurgical injuries, and if left untreated, they can heal on their own, with symptoms usually resolving significantly in about 2 weeks. This is because the mainstay of treatment for concussions is rest. If the corresponding symptoms exist, symptomatic treatment can be taken. If headache, you can take oral painkillers, such as diclofenac sodium, ibuprofen. If dizziness is noticeable, you can take oral vertigo stop. If left untreated, their symptoms will subside. However, a small number of patients may have persistent dizziness, headache, insomnia, and anxiety for more than 3 months, and at this moment, it is necessary to consider the combined post-traumatic brain injury syndrome. For post-traumatic brain injury syndrome, treatment is also generally needed, otherwise, it is very likely to seriously affect the quality of life of the patient, and complete recovery can be achieved through psychological, physical and medication treatments.
