DESCRIPTION:No electrophysiological\, neuroimaging or genetic markers have 
 been established that strongly relate to the diagnostic separation of the 
 depressive phases of Bipolar Disorder (BD) and Major Depressive Disorder (
 MDD). This talk will describe the potential of features\, extracted from t
 he recording of electrical activity from the outer ear canal\, in a proces
 s called Electrovestibulography (EVestG)\, for identifying depressed and p
 artly remitted/remitted MDD and BD patients from each other.\n\nMethods. F
 rom EVestG data sensory vestibulo-acoustic four features were extracted fr
 om both background (no movement) and using a single supine-vertical transl
 ation stimulus to distinguish 27 controls\, 39 MDD subjects and 43 BD subj
 ects.\n\nResults. Using leave-one-out-cross-validation\, unbiased parametr
 ic and non-parametric classification routines resulted in 78-83% (2-3 feat
 ures)\, 80-81% (1-2 features) and 66-68% (3 features) accuracies for separ
 ation of MDD from BD\, controls from depressed (BD & MDD) and the 3-way se
 paration of BD from MDD from control groups respectively.\n\nConclusions. 
 EVestG features can identify depressed and partly remitted/remitted MDD an
 d BD patients from each other.\n\nSpeaker(s): Brian Lithgow\, \n\nRoom: PL
