Abstract

Infantile autism is a complex behavioral syndrome of unknown etiology.

Recent research has shifted away from psychogenic hypotheses to a

variety of possible genetic, neuroanatomical, neurophysiological and

neurotransmitter causes. The present paper examines very recent

research concerned with these major biogenic hypotheses. Linkages among

the various hypotheses are explored, along with problems in conducting

empirical research in this area. The review concludes with an analysis

of the current state of understanding of the biological bases of autism

and a discussion of implications of biogenic hypotheses for clinicians,

educators and parents who work with autistic individuals. The principal

conclusion of the review is that despite many promising hypotheses, the

current literature is filled with conflicting findings and no one

hypothesis has appeared to take center stage.
