In order to assess the early presenting symptoms and signs of myotonic dystrophy in childhood, 12 subjects (four females and eight males), offsprings from eight different families, were examined. The patients' ages ranged from six to 15 years and their course has been followed for four years. The family history, the presenting symptoms, the clinical features and course, the mental evaluation, the electromyographic, ophthalmological and histopathological findings, the serum enzymes, the cardiovascular and endocrinological systems of all the subjects were discussed. The authors observed that, under the same conditions of age and duration of illness, the disease is worse in those patients whose mother is the affected relative and that same investigations (EMG, ERG, echocardiography and muscle biopsy) were altered also in the pre-clinical stage of the disease.
