Features of Auditory Brainstem Response Spectral Representations as Tools for ADHD-Diagnostics

Mathematical Statistics
Abstract (Swedish)
ADHD is a psychological disorder which has become significantly
more prevalent and much debated in the last decades. This study
investigates the possibilities in developing quantitative diagnostic tools
for psychiatric assessment of ADHD based on spectral representations
of Auditory Brainstem Responses (ABR). Two different approaches
to data pre-treatment are adopted, followed by estimates of power
spectral densities, cross power spectral densities and time-frequency
distributions. From these, features are extracted and examined on
their merit as disorder-specific traits. The subject sample consists of
ABR:s from 69 individuals; 36 of which are diagnosed with ADHD and
33 healthy controls. Using a band-pass pre-processing method,... (More)

significance in difference between disease groups is found for females in
terms of dominant frequency, bandwidth, spectral purity and
spectral slope in the power spectral density estimate. (Less)
