[A case suspected of dystonia with marked cerebellar atrophy with torsion dystonia of the neck and cerebellar ataxia that developed during pharmacologic schizophrenia treatment].

A 46 year-old man with schizophrenia had taken several anti-psychotic drugs since 25 years of age. From ~35 years of age, he noticed occasional neck torsion to the left, and later an ataxic gait; both symptoms gradually worsened. On admission, the patient was taking olanzapine (5 mg/day) and biperiden hydrochloride (1 mg/day) because his schizophrenia was well controlled.

A novel nonsense mutation in a Japanese family with ataxia with oculomotor apraxia type 2 (AOA2).

We report a 67-year-old Japanese woman with ataxia with oculomotor apraxia type 2 (AOA2). She was born to consanguineous parents and showed a teenage onset, a slowly progressive cerebellar ataxia and sensory-motor neuropathy and an elevated level of serum alpha-fetoprotein (AFP). All of these clinical features were consistent with typical AOA2.
