Introduction Spino-cerebellar ataxia or SCA are dominant neurological diseases caused by mutations in several genes. According to social and cultural contexts, especially in populations with low education level, the advent of such diseases might generate other kinds of suffering beside those caused by the physical impairment and disability. The aim of this work was to determine the impact of this disease in patients and their relatives. Methods It was a qualitative approach carried out through semi-directive clinical interviews, neuropsychiatric observations and the administration of the Hamilton depression scale. Results The study included a polygamous family in which mothers had 10 and 12 maternities. Neurological manifestations concerned four children of the same siblings and the father in a subtle form. The mother of these children was designated as responsible for the transmission of the disease and presented a reaction depression. Irritability, anxiety and depression reactions were observed in two patients and an unaffected brother. The advent of the disease was associated to the hatching of a latent familial conflict related to the father's status that has been established only after four years. Conclusion In a social and cultural setting of polygamy, the advent of dominant ataxia with anticipation might revive latent familial conflicts and have psychological and social repercussions on the affected individuals and their relatives.
