| چکیده | ||
| Attention deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder. It is characterized by difficulties in allocating and sustaining attention, impulsivity and hyperactivity According to the DSM-5, three presentations of ADHD are described: combined, predominantly inattentive, and predominantly hyperactive/impulsive. Theta-beta ratio (TBR) or inattention index, which is referred to increased theta band power (typically 4-7 Hz) and, in particular, increased theta relative to beta band power (typically 13-30 Hz) has been the most reproducible psychophysiological finding in ADHD. The present study aims to review the literature on QEEG parameters related to ADHD. Due to the increased theta, TBR is reported by many investigators as a consistent characteristic of ADHD. However, it is not the diagnostic measure for all individuals with ADHD. TBR is unnecessary in making the diagnosis for all ADHD presentations. In other words, review of studies suggests that TBR could not be a comprehensive diagnostic measure for all ADHD subtypes. It should not be generalized for all presentations. Rather, each presentation could have its specific QEEG measure. Therefore, a QEEG spectrum classification of ADHD population would be an important notification. | ||
