Subclaims¶

q3 i? Among the three ADHD subtypes, the inattentive type had the most delayed latencies in wave III (P = 0.000), wave V (P = 0.002), I-III interval (P = 0.001) and I-V interval (P = 0.002). → Mohamed A. Ahmed 2014

q3 · i? · associational · r1

One-way ANOVA comparing ABR means across ADHD subtypes; e.g. wave III mean was 3.78 in ADHD-I versus 3.53 (ADHD-C) and 3.43 (ADHD-HI). Waves I, II and interval III-V did not differ significantly across subtypes.

"The delay was significantly high in inattentive type in wave III (P = 0.000), wave V (P = 0.002), I-III interval (P = 0.001) and I-V interval (P = 0.002) in comparison to the combined and the hyperactive impulsive type (Table 4)."

• ADHD children show significantly prolonged ABR wave III, IV, V and interpeak I-III, III-V, I-V latencies compared with controls — related
• The inattentive ADHD subtype has the worst learning ability score among ADHD subtypes — related
• Learning disability scores correlate negatively with ABR wave III/IV/V latencies, I-III and I-V intervals, and epileptiform EEG activity — related
• Epileptiform EEG activity is more prevalent in the inattentive ADHD subtype — related
