Early-onset multisystem degeneration with central motor, autonomic and optic nerve disturbances: unusual Riley-Day syndrome or new clinical entity?
We report a 21-year-old woman presenting with a slowly progressive tetraparesis, optic nerve atrophy on both sides, and autonomic disturbances since early childhood. The patient has been carefully followed up for 5 years with clinical and ancillary investigations. The results and the time course strongly suggest an underlying degenerative syndrome affecting parts of three major systems: autonomic, motor and visual. Some symptoms resemble familial dysautonomia (FD, Riley-Day syndrome), however, hallmarks of FD, such as absence of fungiform papillae of the tongue, abnormal reaction on intradermal histamine injection, absent tendon reflexes, are missing, and central motor disturbances have not been described in FD. We consider this syndrome a slowly progressive multisystemic degeneration with two unusual hitherto unreported features: the combination of affected systems (autonomic and motor systems, optic nerves), and the early onset.
