Abstract

The objective of this paper was to determine the degree of diagnostic overlap between attention deficit disorder with hyperactivity (ADDH) and conduct disorder (CD) and to see whether ADDH children show a different pattern of demographic, familial, and developmental correlates compared to CD children. The sample for this study consisted of 2,697 4- to 16-year-olds who participated in the Ontario Child Health Study. In terms of diagnostic overlap, ADDH and CD occurred together more often than by chance alone, particularly among girls. Pure groups of ADDH and CD children differed in a variety of ways. In general, ADDH children were younger and had experienced more developmental delays and less psychosocial disadvantage than the CD children. No differences were found with respect to associated impairments, a measure of severity. Children with both ADDH and CD (a mixed group) appeared to represent a true hybrid disorder rather than one diagnosis or the other. These findings support the validity of ADDH compared to CD, at least in terms of the pattern of correlates.

Attention Disorders

Attention is involved in all cognitive activities, and attention disorders are reported in patients with various neurological diseases. Here are the latest discoveries pertaining to attention disorders.

4H Leukodystrophy

4H Lekodystrophy involves hypomyelination, hypogonadotropic hypogonadism and hypodontia. It is also known as POLR-3Related Leukodystrophy. 4H syndrome symptoms include delayed or abnormal puberty, issues with central nervous system signal transmission, abnormal development of teeth, and symptoms tend to progressively get worse over time. There is not yet a known cure.
