title: [A case of early onset cerebellar ataxia with hearing loss, mental disturbance and primary hypogonadism].
abstract: A 14-year-old girl, whose birth and developmental history were normal till the age of 7, was admitted to our hospital because of slowly progressive difficulties in walking, speaking and hearing. She also complained of absence of menstruation. She showed poor school records since the age of 7. On neurological examination, she showed limb and truncal ataxia. There was no nystagmus but slurred speech was found. Muscular power was good and her sensory system was normal. Tendon reflexes were equally present, and plantar reflexes were flexor. Bilateral moderate nerve deafness was also present. Mental deficiency was diagnosed on an intelligence test. Brain CT and MRI showed cerebellar atrophy. Gynecological examination revealed scanty pubic hair and small uterus. Karyotype was 46XX. Endocrinological studies demonstrated high level of FSH, low level of E2, and the normal response to pituitary stimulation with LHRH, indicating the existence of primary hypogonadism. Although the etiology of this multisystem disorder is unknown, it is possible that both nervous and endocrine disorders were genetically determined.
