[Female with dentatorubral-pallidoluysian atrophy followed for 14 years from the pre-clinical stage: availability of gait analysis].
We presented a 28-year-old female with dentatorubral-pallidoluysian atrophy (DRPLA) who had been followed from the pre-clinical stage. Her mother and elder brother were diagnosed as DRPLA at autopsy. Though the genetic diagnosis was not performed, we diagnosed this patient as DRPLA from her clinical course and family history. She first visited our hospital at age 14 with a symptoms of mental retardation. Generalized tonic-clonic type epilepsy developed at age 15, and valproate was prescribed from age 24. Gait disturbance and mental deterioration gradually progressed from age 15. We had performed gait analyses and brain MRI studies at regular intervals from age 14 to 27. She could walk even with gait disturbance until her early 20s. At one year after marked ataxia was recorded on gait analysis, she rapidly regressed and became unable to walk. Following this patient over a long period of time presented an opportunity to gather informative data regarding the progression of this disorder.
