Most adult patients with pervasive developmental disorder（PDD）who consult with psychiatrists for the first time may have normal intelligence. In diagnosing high-functioning PDD to adult patients, we should pay much attention to psychological consistency which exists between developmental problems in childhood,developed personality, recent problems in social adjustment, and manifested psychiatric symptoms.
 In order to understand these relationships,considering the patients’type of ego structure（“PDD ego type”）seems to be useful. “PDD ego type”is characterized by their unique selfuniverse image which takes form of grid one（just like a touch panel）, which is decisively different from the form of a radial or concentric circle held by most people（Jung,C.G）. This self-universe image characterizes adult PDD patients’psychiatric symptoms, unsuitable social performance, and their “personality.”
