We studied 15 families with autists, 15 with Down's syndrome and 15 asymptomatic children. Patients' age ranged from 5 to 15 years-old. The parents of these three families' groups were appraised in regard to their family dynamics, to relate those symptoms to the functioning of an autist family, in a comparative study. Details were provided of the families, the overall autistic features, the autist's family, the family and the mental health, their limitations and difficulties throughout the vital cycle. An attempt was made to locate the factors that aid the family in hindering the healthy emotional development of its members. The field research was achieved by use of the instruments of the Family Dynamics Evaluation, (Carneiro, 1983). The data gathered were statistically compared. Considering the family population studied (n = 45), we found that the autists' families and victims of Down's syndrome made it difficult to sustain the emotional health of group members. We conclude that the autist's family dynamics caused difficulties to the emotional health of the group's members.
