The pervasive disorders of development (TPD) or disorders within the spectrum of autism (TEA) are two terms which are often used to describe a well-defined group of behaviour disorders characterized by changes in social interaction and language communication together with repetitive behaviour patterns. This group of disorders has multiple etiologies and the clinical manifestations vary in severity. In this study the incidence of a selected group of neurological changes and neurodiagnostic tests in 421 children with TDP is analyzed. 11% of the children had genetic disorders such as chromosomial disorders, genetic syndromes and family incidence. 18% of the children had motor disorders with hypotonicity being the commonest (85%). 71% of the children were stereotyped. 59% of the children had cogniscitive functions which were appropriate, or nearly so, for their chronological age. 28% of the children had language regression. 13% had epileptic crises. The electroencephalogram and cerebral magnetic resonance were abnormal in 29% and 19% respectively of the children on whom these tests were done.
