Vestibular dysfunction in familial dysautonomia. The Riley-Day syndrome.

We report the bilateral absence of response to tests of vestibular function in 5 patients with familial dysautonomia.

Familial dysautonomia (Riley-Day syndrome).

Familial dysautonomia, also known as Riley-Day syndrome, is a disorder of autonomic nervous system with an autosomal recessive mode of inheritance. Reduction and/or loss of unmyelinated and small myelinated fibers is found, as reduction of dopamine beta-hydroxylase in blood. The diagnosis is based on clinical features: diminished lacrimation, insensitivity to pain, poor temperature control, abo...
