Introduction:
Attention deficit hyperactivity disorder (ADHD) is a heterogeneous condition and often coexists with other disorders that may go undetected, such as communication and language disorders.
Aims:
The aim of this study was to evaluate semantic processing of language in children with ADHD by recording the N400 component of cognitive evoked potentials.
Subjects And Methods:
The N400 component was recorded in visual mode while a semantic congruence/ incongruence task was being performed by a sample of 36 children with ADHD and 36 control children.
Results:
Latency and amplitude of the N400 component were seen to increase and decrease, respectively, in all areas of the brains of the children with ADHD with respect to the children from the control group.
Conclusions:
These findings clearly reveal the existence of a deficit in the semantic processing of language in children with ADHD that is associated to their attentional dysfunction.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
