Abstract
The aim of the present study was to investigate the causes of polyneuropathy in teenagers and to describe some characteristic clinical, laboratory, electrophysiological and pathological features. Forty-five patients with peripheral nervous disorders aged 13-19 were studied. Hereditary polyneuropathy of different types was diagnosed in 28 patients (62%); nine showed chronic inflammatory demyelinating polyneuropathy (CIDP) and two showed vasculitic neuropathy. In two more cases polyneuropathy was attributed to toxic agents, while among the rest, one was diagnosed as metachromatic leucodystrophy (juvenile type), one as adrenoleucodystrophy, one as porphyric neuropathy and one as Fabry disease. The high incidence of hereditary neuropathies in teenagers differs from that in adults, but is similar to that encountered in children. In our study, CIDP appears to be a frequent cause of neuropathy in teenagers, while the other causes are broadly similar to those found in studies concerning children rather than adults.
