Digit and letter alexia in carbon monoxide poisoning.

Shen Q, Rong X, Pan R, Peng Y, Peng W, Tang Y - Neural Regen Res (2012)

Bottom Line: The results revealed that the patient exhibited digit and letter alexia, while the ability to read Chinese characters was preserved.Following treatment, reading and writing ability was improved and electroencephalographic abnormalities were ameliorated.Overall, our experimental findings demonstrated that delayed encephalopathy following acute carbon monoxide poisoning was characterized by digit and letter alexia.

ABSTRACT
This study examined a 24-year-old patient with delayed encephalopathy, who was admitted to hospital with complaints of headache and visual impairment 1 week after acute carbon monoxide poisoning. The results of a visual field assessment, electroencephalography and head magnetic resonance imaging indicated damage to the cerebral cortex. After a 2-week treatment period, the patient had recovered from the visual impairment, but exhibited digit- and letter-reading difficulty. The Chinese aphasia battery and the number and letter battery supplement were conducted. The results revealed that the patient exhibited digit and letter alexia, while the ability to read Chinese characters was preserved. In contrast, the patient exhibited a deficit in Chinese character writing, while number and letter writing remained intact. Following treatment, reading and writing ability was improved and electroencephalographic abnormalities were ameliorated. Overall, our experimental findings demonstrated that delayed encephalopathy following acute carbon monoxide poisoning was characterized by digit and letter alexia.

Visual impairment of the patient before and after treatment.Visual field examination was performed at day 2 when the patient was admitted to the hospital. Right homonymous hemianopia was evident in both eyes pre-treatment (A). After 2 weeks of treatment, the patient's visual deficit had fully recovered (B).
