title: [The progressive reduction of functioning in the course of mucopolysaccharidosis type IIIA - longitudinal study of two siblings].
abstract: BACKGROUND
  This paper presents a description of changes in the functioning of two siblings diagnosed with mucopolysaccharidosis type III A. Both are under specialist care exercised by the Rehabilitation, Care and Education Centre in the city Kielce, including care of a oligophrenopedagogue, a psychologist, a speech therapist and a physiotherapist.
  
  
  OBJECTIVE
  Evaluation of changes in functioning of two siblings diagnosed with mucopolysaccharidosis type IIIA.
  
  
  METHODS
  The longitudinal study covered two children with MPS type IIIA. During the 29 months of observation, there were six measurements on the basis of PPAC Gunzburg Inventory in the Polish adaptation by Tadeusz Witkowski. The results are shown in the form of PPAC diagrams and profiles of functioning.
  
  
  RESULTS
  Despite the differences in the presence and severity of somatic and neurocognitive symptoms, functioning both of the boy and the girl does not differ from functioning described in the literature. Therapeutic interventions have produced short-term improvements in its area of self-service, communication and activities.
  
  
  CONCLUSIONS
  Despite the similar trend of changes in functioning, there is an inter-individual variability in the quality of patterns and dynamics of progress. The progressive decrease in the level of functioning in patients with MPS IIIA does not preclude the acquisition of new skills. They are not permanent, however. There is a need for functional assessment in order to learn more about the specificity of the disease and to assume an individualised therapeutic approach aimed at improving the quality of life of patients with MPS IIIA and, indirectly, the quality of life of their families.
