| progressive balance difficulties, impaired gait and coordination (ataxia), slurred speech, diplopia, and hypoacusis, insidious cognitive decline, esophoria. Upon exam, signs of both cerebellar and sensory ataxia (positive Romberg’s sign) as well as chorea, myoclonus, areflexia, and complete loss of vibration sense were found. Bradykinesia and marked postural instability. Eye examination revealed broken up smooth pursuit, nystagmus, mild dysconjugation of lateral eye movements, hypometric saccades and partial restriction of vertical gaze. Psychometric evaluation revealed deficits in information processing speed, working memory, attention, and visuospatial skills. A mild sensorineuronal hearing loss. | | - | movement disorder (ataxia) | |

| plurimetabolic syndrome. At age 30 years, he noted disturbed balance, and ataxia and severe axonal neuropathy were diagnosed. On examination at age 32 years, he had slowed ocular pursuit movements but with full range of motion. He had severe gait ataxia, imbalance, and trunk ataxia, as well as clumsiness of the hands. Achilles tendon reflexes were absent. dysarthria, obesity, chronic motor axonopathy, moderate sensory neuropathy at the upper limbs, mild neurogenic atrophy. | | - | movement disorder (ataxia) | |

| dystonic ulnar deviation of the left upper limb with distal predominance. She showed intermittent facial and jaw opening dystonia. At rest, she had marked postural instability caused by trunk ataxia, which is aggravated by motor actions like e.g. lifting the upper limbs. severe dysarthria, incomplete horizontal and vertical external ophthalmoplegia and ataxia were observed as clinical features of MIRAS.

Also her feet show unpatterend jerky movements, which may be classified as myoclonus but are also similar to limb movements in benign hereditary chorea. external ophthalmoplegia, slowing of voluntary saccades and gait ataxia started. | | - | movement disorder (ataxia) | |

| developed gait disturbance by the age of 35, progressing to increasing clumsiness in lower extremities, dysarthria, diplopia, and occasional amnesia at the age of 44. She developed ataxia, slight polyneuropathy, and external ophthalmoplegia. At the age of 46 she had slightly increased plasma creatine kinase levels and symmetrical cerebellar peduncular white matter signal intensity increase in brain MRI. The first epileptic seizure, requiring treatment by general anesthesia, oc- curred at the age of 55, after which she was hospitalized permanently. From her 30's, she received psychiatric care due to anxiety and depression. A neuropsychological examination revealed decrease in visual reasoning and memory functions. She deceased at the age of 56 due to pneumonia and pulmonary embolism. | | - | movement disorder (ataxia) | |
