Genetics and Biochemistry in Attention Deficit Disorder

Abstract

we take the . . . position that genetics itself may reveal natural subgroups of ADD [attention deficit disorder] and may provide the groundwork for a biochemical breakthrough / biochemical hypotheses / serotonergic hypothesis / catecholaminergic hypothesis describe a strategy for obtaining more homogeneous subtypes: genetic latent structure analysis review genetic studies of ADD derived from the staples of genetic epidemiology—family, twin, and adoption studies / as a framework for this review, we highlight some problems raised by diagnostic and etiological heterogeneity in ADD are ADDH [attention deficit disorder with hyperactivity] and Tourette syndrome related overrepresentation of adoption among ADD patients / dysmorphology (PsycINFO Database Record (c) 2019 APA, all rights reserved)
