Comparison of diffusion tensor imaging parameters of the patient and control groups.

	Lower dorsal ARAS		Lower ventral ARAS		Upper ARAS
	FA	TV	FA	TV	FA	TV
Patient group	0.40 (±0.04)	350.26 (±168.93)	0.36 (±0.04)	189.34 (±138.11)	0.35 (±0.03)	20354.54 (±5958.37)
Control group	0.41 (±0.03)	375.58 (±152.75)	0.39 (±0.42)	323.23 (±120.80)	0.36 (±0.01)	19340.92 (±5559.88)
p-value	0.127	0.441	0.001*	0.001*	0.104	0.388

Values represent mean (±standard deviation); ARAS, ascending reticular activating system; FA, fractional anisotropy; TV, tract volume.
