Clinical features and risk factors of post-concussion syndromes after mild traumatic brain injury / 中华神经医学杂志

ABSTRACT

Objective To explore the clinical features and risk factors of post-concussion syndrome (PCS) in patients after mild traumatic brain injury (mTBI).Methods Two hundred and seventy-six patients with mTBI,admitted to our hospital from December 2016 to June 2018,were chosen in our study;114 patients (41.30％) developed PCS.The epidemiological data,causes and sites of brain injury,clinical symptoms,and duration and time of PCS occurrence were investigated.Multivariate Logistic regression was used to analyze the risk factors of PCS in patients with mTBI.Results The most common syndromes of PCS were headache (89.13％),amnesia (63.77％),dizziness (63.04％) and nausea (57.61％).The incidence rate of PCS was 51.75％ in the first month of injury and decreased with time.Multifactor Logistic regression analysis showed that student (P=0.041,OR=0.36,95％ CI:0.14-0.95),electric bicycle accidents (P=0.043,OR=0.54,95％CI:0.30-0.98),and occipital injury (P=0.022,OR=0.28,95％CI:0.09-0.83) were independent risk factors of PCS of mTBI patients.Conclusion Patients with mTBI,especially those who are students,victims of electric bicycle accidents and victims of occipital injury,should be highly alert to the occurrence of PCS,and need reasonable rest,symptomatic treatments and memory training or other rehabilitation treatments within one month of injury,in order to prevent the development of PCS.
