OBJECTIVES: To clarify clinical picture of transient @entity2045 state in elderly @entity1 . METHODS: The Aizawa Hospital database was searched to identify all @entity1 with transient @entity2045 state with or without asterixis between April 2006 and June 2013. Medical records, brain images and laboratory data including electroencephalograms and electromyograms were reviewed. RESULTS: We found 26 @entity1 : 10 @entity1 and 16 @entity1 , and their ages ranged from 56 to 96 years (79.7  9.9 years, mean  standard deviation). The affected sites of the @entity2045 were predominantly the lower face, neck and upper extremities. The @entity2045 appeared at conscious resting condition, slightly exaggerated by posturing or action. Asterixis was observed in eight @entity1 . @entity36890 were 1.70  0.94s long. The interval of @entity36890 was 4.47  2.44s. @entity36890 were composed of 9.5  2.5Hz @entity2472 , and single @entity2472 were 44.4  12.3ms in duration. Most of the @entity1 suffered from @entity102 , but they were basically independent in activity of daily living. Oral administration of @entity2053 was effective. CONCLUSIONS: Transient @entity2045 state has relatively stereotyped features. The pathophysiology may include some @entity209 on a background of age-related arteriosclerotic changes. Its prognosis is benign, and prompt oral administration of @entity2053 abolishes it. Further investigations will be needed to clarify its cause and pathophysiology.
