Many of the disturbances resulting from dysregulations in the autonomous nervous system of children with cerebral palsy are rarely discussed in the doctor's praxis. Nevertheless, they are causes of trouble and worry for the parents. For this reason we started an inquiry into this matter. Questionnaires were sent to the parents of 452 C.P. patients. 374 were answered with sufficient care. The following factors were evaluated: sleep, bladder and bowel activity, temperature regulation, vomiting, sweating, blood circulation, growth. The C.P. children were compared to their own siblings especially to the next younger ones. The diagnoses were as follows: Spastic tetraplegia 197 patients. Spastic hemiplegia 44 patients, Athetosis 33 patients, Mixed cases of spasticity and athetosis 82 patients, Other 15 patients. The degrees of handicap in terms of motor development were: severe (unability to sit unsupported) 166 cases, moderate (unability to kneel or walk unsupported) 118 cases, mild (ability to kneel and/or walk unsupported) 87 cases. Summarized, the statements of the parents gave the following results: sleep disturbances: 169 cases (46%), constipation: 145 cases (39%), tendency towards temperature dysregulation: 112 cases (30%) , tendency towards increased vomiting: 91 cases (25%), sweating increased or decreased: 110 cases (30%), irregular and frequent voiding of bladder: 92 cases (25%), unstable regulation of blood circulation: 101 cases (27%), cold skin: 264 cases (71%), body-length deficit: 119 cases (32%), low-weight: 177 cases (48%), feet too small for age: 252 cases (68%). Results are related to diagnosis and severeness of handicap. In addition, it is discussed, whether there are relations between several of the investigated factors. The influence of the patients sex is discussed.
