causa neurobiológica para o autismo

There no need to postulate a defective brain. Althought it is possíble. Autism probably is contingency shaped. Enrivoment should be good to development ocurr. "neurobiological causes of autism are intuitively appealing, medical research has failed to provide conclusive evidence for a neurological, biological, or genetic cause for autism. In the introduction to a special issue of the Journal of Autism and Developmental Disorders devoted to contemporary research in autism, Alexander, Cowdry, Hall, and Snow (1996) stated, "No consensus regarding causes or potential cures for autism is assumed. This is a problem that is not yet solved" (p. 118). Likewise, Bailey, Phillips, and Rutter (1996) stated, "a replicable, neurophysiological basis for autism has not yet been identified" (p. 89). More recently other neurobiological researchers have reached similar conclusions. Lauritsen, Mors, Mortensen, and Ewald (1999) stated, "Infantile autism is a heterogeneous disorder of unknown etiology" (p. 335). Trottier, Srivastava, and Walker (1998) reported, "The etiology of autism is complex, and in most cases the underlying pathologic mechanisms are unknown" (p. 103). hus despite the prevalence of the neurobiological explanation, it is evident that no conclusive scientific evidence for a neurobiological cause for autism currently exists"
