| Abstract |
We reported a patient who presented unusual writing disturbances following multiple cerebral infarctions. His dysgraphia was characterized by an excess of strokes in letter writing; extra-strokes. He had no signs of aphasia, alexia, apraxia, and his general intellectual ability was within normal range. He was able to copy geometric figures correctly. Furthermore, he made few errors other than extra-strokes. The extra-strokes occurred only when he wrote with his right hand, and the errors increased in the eye-closed condition. They occurred irrespective of the position of stroke in the letter, top or bottom, or right or left, and occurred more frequently in the letters that had repeated sequences of identical strokes. The errors decreased when he was promoted to write slowly. We suggested that the extra strokes in this case could be attributed to disinhibition of motor programs and impaired monitoring function in letter writing. |
