We report a 63-year-old woman who presented myotonia and parkinsonism. The patient was well until 15 years of the age when she noted that the ring finger of her left hand at times flexed when she did not intend to do so. She noted weakness in her left upper extremity at the age of 40, and difficulty in relaxing her hand grip at 45. She had an onset of tremor in her right foot at age 50, which was foll-owed by difficulty in gait and hand writing. She was admitted to Juntendo University Urayasu Hospitalwhen she was 63-year-old.

Her mother, two sisters, and a son were affected with similar muscle weakness and myotonia.
