| Popis: | Migraineurs often experience auditory-related symptoms such as increased sensitivity to sounds and difficulty in processing auditory information. There is some evidence that there may be abnormalities in certain brain regions; thus, there is impetus to use auditory assessment tools that probe different regions in the brain. The goals of this study were to identify whether innate differences exist in auditory measures between migraineurs during attack-free periods and non-migraineurs, and if asymmetries exist between the ears in migraineurs. The migraine group consisted of 10 adult female subjects with a history of migraine headaches, and the control group consisted of 10 adult female subjects with no history of migraine headaches. Results on pure tone audiometry, immittance audiometry and uncomfortable loudness level tests indicated no significant differences between the groups. However, the amplitude growth from 40 to 80dB nHL for auditory brainstem response (ABR) peak V and middle latency response (MLR)... |
