“…[21] A 53-year-old woman presenting with callosal disconnection syndrome (CDS) as a result of a stroke presents with ideomotor apraxia, and tactile anomia with the left hand, cross-replication of hand postures, cross-localization of the ngers, and constructional impairment with the right hand. [22] Epilepsy has been reported in up to two-thirds of people with corpus callosum hypoplasia or partial hypoplasia. The corpus callosum is the main pathway of epileptic generalization.…”

Marchiafava-Bignami disease (MBD) is a rare disease with only a few reports worldwide. To describe clinical features and identify difficulties in the treatment of alcohol-related MBD, we performed a retrospective study of 21 MBD inpatients at a hospital in Southwest China. The interquartile range (IQR) for age was 53-66, with a mean age of 59 years. The IQR for drinking duration was 30-40, with a mean drinking length of 35.5 years. Cognitive impairment and unconsciousness were the most common symptoms (n=13, [61.9%]). Consciousness disorders, delirium, irritability, and ataxia are more prevalent in type A MBD patients; seizures, cognitive impairment, and limb weakness are more common in type B MBD patients. Routine blood and biochemical tests in alcoholic MBD patients may demonstrate orthocytic hypochromic anaemia and impaired liver function. Patients' uric acid (UA), potassium, and sodium levels may be normal. Eight patients received thiamine, while one received steroids. The average stay was 15 days. At the time of discharge, there had been no deaths. One patient died six months after being discharged, while another died two years afterwards. Indeed, MBD is a rare alcohol-related disorder with a variety of clinical symptoms. With thiamine treatment, prognosis is positive.

“…60,61 These findings may suggest distinct interhemispheric pathways for the reading/writing of kanji and kana or the reorganization of interhemispheric transfer that is different for kanji and kana following callosal lesions. 62,63 Another possibility is that the right hemisphere gained a compensatory function for the reading/writing of either kana or kanji at the chronic stage.…”

Reading and writing are important in modern society. Focal brain injuries, such as stroke, selectively impair reading and/or writing, leading to alexia and/or agraphia, respectively. In this review, I describe pure alexia and agraphia in Japanese; alexia and agraphia associated with aphasia are excluded unless otherwise specified.Dejerine established the theoretical basis for alexia with agraphia and alexia without agraphia. 1 Interruption between the visual cortex and the left angular gyrus was assumed to result in alexia without agraphia. This model was revived by Geschwind as a disconnection syndrome. 2 During the early 20th century, pure alexia and/or agraphia in Japanese were reported in Japanese journals, including cases of pure alexia, 3,4 alexia with agraphia, 5 and apraxic agraphia. 6 These
