Small world networks of brain network in mild traumatic brain injury patients:a functional magnetic resonance image study / 中华行为医学与脑科学杂志

ABSTRACT

Objective To analyze the effects of mild traumatic brain injury ( mTBI) on functional brain network parameters and to study the properties of small world of patients. Methods Ten patients with mild traumatic brain injury and 13 healthy controls matched by age and sex were collected from the Ninth People's Hospital Affiliated to Medical College of Shanghai Jiao Tong University. Resting functional magnetic resonance images of all subjects were collected. Functional networks were constructed and brain network properties were analyzed. Results The brain injury group and the healthy control group had small world at-tributes in the selected sparseness range. The global efficiency of patients with mTBI patients was significantly reduced compared to healthy control group (0. 174±0. 141 vs 0. 184±0. 062),t=2. 417,P=0. 025),and the shortest path length was increased compared to healthy control group (0. 797±0. 930 vs 0. 734±0. 488),t=-2. 083,P=0. 048). Conclusion The functional brain network of patients with mTBI patients has small world attributes,and the parameters of functional brain network of patients have changed.
