Reversible alexia without
agraphia due to migraine.
Alexia without
agraphia is a syndrome involving impaired communication between the inferior portion of the splenium of the corpus callosum and the medial occipitotemporal gyrus of the dominant hemisphere [5].
Since knowledge of the characteristic of
agraphia in patients with AD or MCI is still lacking, this study could provide some baseline data in this field.

The plot in novelist Howard Engel's new memoir involves the treatment of a rare neurological condition called alexia sine
agraphia, which has whacked his ability to read but not his capacity to write.
The clinical features that are more common with a dominant left cerebral hemisphere lesion include aphasia,
agraphia, acalculia, apraxias, a left gaze preference, a right visual field deficit along with right-sided hemiparesis, and a right-sided hemisensory loss.
The MMSE is a 30-point structured clinician-rated interview scale incorporating pencil-and-paper tasks for assessing nine items: memory, orientation, attention, verbal fluency, nominal aphasia, receptive aphasia plus receptive apraxia, alexia,
agraphia, and constructional apraxia [23].
For example, alexia and
agraphia (difficulty reading and writing numbers) is almost always associated with lesions to the left hemisphere which also frequently involve neurological systems associated with aphasia (word retrieval difficulties) and reading disorders.
