Brief Smell Identification Test

Brief Smell Identification Test decreases inferior lateral ventricular expansion in humans (β = −10.71 mm3/year).

“slower inferior lateral ventricular expansion (β = −10.71 mm3/year, PFDR = 0.015) in the MRI trajectory analysis.”

Brief Smell Identification Test decreases hippocampal atrophy in humans (β = 10.89 mm3/year).

“Higher BSIT scores were also significantly associated with slower hippocampal atrophy (β = 10.89 mm3/year, PFDR = 0.001)”
