A 64-year-old right-handed @entity1 was admitted because of increasing clumsiness of the right hand and difficulty in walking since 8 months earlier. The WAIS revealed verbal IQ 124, performance IQ 104 and full scale IQ 115. Neurological examination revealed slight @entity4653 and @entity1319 . The right upper extremity showed Gegenhalten, @entity400 , @entity3520 , marked grasp reflex, grasping and groping behavior. @entity717 were slow and clumsy on the right side. However, neither ideational nor ideomotor apraxia was observed. Tendon reflexes were slightly exaggerated on the right side. Plantar responses were normal. The @entity1 had difficulty in initiating forward walking and turning movements. Once started, he walked dragging his right foot ahead of the left with short steps. A line on the floor was of no benefit. He could not stride across the line on the floor in front of him. Analysis of gait with floor reaction force revealed that the single step rhythm of his frozen gait was about 1.5 Hz, which contrasted with the high frequency seen in @entity191 . MRI demonstrated @entity194 of the frontal and parietal lobes on both sides. 123I-IMP single-photon emission CT demonstrated severe hypoperfusion of the left frontal and parietal lobes. Frozen or shuffling gait is a popular symptom as well as unsteady gait and tendency to fall in @entity528 . It may result from @entity75 . Lack of improvement in freezing by the visual input contrasts with @entity191 and may be related to dysfunction of the mesial part of the frontal lobe or the parietal lobe involved in @entity528 .
