A 62 year old, right handed man developed a pure agraphia as the result of a left temporal lobe stroke. Isolated writing disturbances persisted for seven months until he had a second cerebrovascular accident resulting in total aphasia and right hemiplegia. A CAT scan obtained four months after the first episode showed a localised dilatation of the posterior portion of the left Sylvian cistern and patchy areas of low absorption in the left temporal lobe. The report supports suggestions that localised damage to the language area can produce a pure agraphia as the sole detectable disorder of language organisation.

This paper presented a case of a right-handed male who showed a right hemiplegia without aphasia and apraxia. He lost the ability to write with the left hand. A 56-year-old right-handed man, who had a daughter of left-handedness, was sent to our hospital with a homonymous hemianopsia, facial weakness, spastic hemiparesis and sensory disturbance in the right side. CT scan revealed an infarction in the territory of the left middle cerebral artery. On a month after the onset, he was alert and oriented. His speech was normal and verbal comprehension was intact. Although he neglected the right side of the page, he could read and comprehend it correctly. In contrast with his normal abilities to speak, comprehend, and read, difficulties in writing were prominent. Spontaneous writing with the left hand was extremely poor, and he even had difficulty writing his own name. His dictation was also poor, but his writing improved with copying letters. Agraphia had seen even after USN was recovered. Analysis of this case suggested the presence of the dominance for speech, comprehension, and praxis in the intact right hemisphere, and writing center in the damaged left hemisphere.

A 74-year-old right-handed man with multiple cerebral infarction who presented with dementia simulating dementia of Alzheimer type (DAT) is reported. He had been well until April 20, 1987 when he developed transient right hand palsy lasting overnight. Eleven days later, he became confused, disorientated, and amnestic. He was admitted to this hospital on June 8. Physical examination revealed hypertension (170/90mmHg). On neurological examination, his consciousness was clear but he was demented. He showed disorientation, amnesia, and urinary incontinence. His most prominent symptom was disturbance of speech, including fluent aphasia and alexia with agraphia. Additionally, he showed ideomotor apraxia, construction apraxia, right-left agnosia, finger agnosia, and acalculia. On July 9, he had a transient attack of right hemiplegia with confusion. The brain CT scan performed on admission was unremarkable except for cavum septi pellucidum and a small low density area in the right basal ganglia. However, single photon emission computed tomography (SPECT) by 123I-labeled N-isopropyl-p-iodoamphetamine disclosed hypoperfusion of the cerebral blood flow in the border zones of the temporoparietal and frontal lobes on the left. A follow-up brain CT scan taken one month later demonstrated low density in the new areas corresponding to hypoperfusion shown by SPECT. Although the clinical features of the present case resembled those of DAT, dementia in this case was regarded as the result of multiple cerebral infarction since it occurred acutely with mild motor deficits, and brain CT scans and SPECT showed lesions indicating focal cerebral ischemia.(ABSTRACT TRUNCATED AT 250 WORDS)

A right-handed man, born of a right-handed family, presented an infarct in the territory of the right middle cerebral artery, with a left hemiplegia, a left lateral homonymous hemianopsia and an expression aphasia. The oral trouble disappeared in some weeks, but later a permanent linguistic deficit persisted, affecting mainly the written language and realizing a clinical picture of alexia-agraphia with Gerstmann's syndrome. The neurolinguistic study showed a preferential alteration of the phonologic system in the written language, and at a lesser degree in the oral modality. The extent of the lesion and the relative integrity of oral expression and comprehension, suggested that these functions were localized in the left hemisphere, whereas lecture, writing, calculation, body-parts notion, laterality notion, had been simultaneously implanted during the ontogenesis in the right hemisphere. The latter was probably also responsible for phonological aspects of written and spoken language, according to a scheme opposite to that of usual right-handers.

A 74-year-old, right-handed woman suffered acute aphasia and left hemiplegia secondary to a cerebral infarction in the right cerebral hemisphere. The lesion was located deep in the parietal lobe and extended to the posterior limb of the internal capsule and the head of the caudate nucleus. The patient's aphasia was characterized by severe impairment in auditory and visual comprehension and auditory retention span, as well as by anomia, agraphia, and dyscalculia. She showed rapid recovery from her aphasia, with residual deficits in writing, naming, calculation, and memory.

A 74 year-old woman was admitted with a right hemiplegia resulting from a left infarct that had totally destroyed the territory supplied by the middle and anterior cerebral arteries. The patient presented with anosognosia and hemiasomatognosia and negligence of the right half-field. She was aprosodic, not aphasic, and there was a severe apraxia and total agraphia. These neuropsychological disorders are discussed in relation to the contradictory data relative to the manual lateralization of the patient. Findings in this case of a "crossed apraxia" show that management of language and of the propositional gestures are not necessarily ensured by the same hemisphere. It also appears that manual preference may be a poor clue for interpretation in terms of functional lateralization.

A method is proposed for studying writing ability in both hands of agraphic aphasics with hemiplegia. In cases with agraphia performance when writing dictation was superior with the paralysed arm. Literal paragraphia was more frequent in the left hand and verbal paragraphia and perseveration were found exclusively on the left side. In a control group of aphasics with agraphia but without hemiplegia, these differences were not noted. It is concluded that this hitherto unknown phenomenon is caused by intersection of the path between the graphic region of the dominant hemisphere and the corpus callosum. Therefore the syndrome is termed "graphic disconnection syndrome".

The performance of five aphasics with agraphia and right hemiplegia showing side differences in writing to dictation is reported on. It was found that writing with the paralyzed arm, supported by a writing aid, was better than writing with the left hand. In a control group of aphasics with agraphia, but without hemiplegia, such side differences were not found. The conclusion is drawn that in aphasia with hemiplegia the lesions intersect the path between the graphic region of the dominant hemisphere and the corpus callosum. Therefore the observed syndrome is termed "Graphic Disconnection Syndrome."

A 75 year-old woman was admitted with a left hemiplegia resulting from an infarct in the right middle artery's territory. Her manual preference was ambiguous from early childhood. She presented with severe bilateral apraxia, autotopoagnosia, finger agnosia, and left spatial neglect. There was, however, no aphasia nor agraphia. When the patient attempted to perform gestures on order, she compulsively produced oral or written language. In this very unusual case, dominance for gesture and dominance for language were strictly independent, each ensured by one hemisphere. The patient's performances in gestual activities, especially dissociation between automatic and voluntary movements, and compulsive linguistic productions, are discussed in relation to this functional lateralization. We suggest that the propositional nature of the responses required in test conditions could activate either voluntary language in the left cerebral hemisphere, or voluntary gestures in the right. A competition between the two hemispheres could explain the patient's linguistic apraxic or behavior in response to orders. Autotopoagnosia, an uncommon symptom, could interfere with apraxia, but is not directly responsible.

Infarction in the anterior cerebral artery (ACA) territory is an uncommon cause of stroke. The clinical findings of ACA infarctions are not fully characterized but include contralateral hemiparesis, urinary incontinence, transcortical aphasia, agraphia, apraxia, and executive dysfunction. We report a patient with a large right ACA infarction, who in addition to previously reported findings also had a complete hemiplegia, profound sensory neglect, and micrographia.
