We describe a patient with left parietotemporal hemorrhage with selective acalculia for addition, multiplication, and division, but with an intact ability to subtract. There was no impairment in the ability to distinguish mathematical signs. This case suggests that different processing systems are
The interhemispheric disconnection syndrome secondary to a callosal haemorrhage is exceedingly uncommon. In the present study, 3 patients with haemorrhages restricted to the corpus callosum are presented. All 3 developed a partial anterior interhemispheric disconnection syndrome: unilateral tactile
Korsakoff's syndrome is characterised by an important impairment in memory in comparison to other cognitive functions. Presence of confabulations is frequent but they are not characteristic of this syndrome. Alcohol abuse is the main cause of this syndrome but it also has been associated to other
In Japan, the multiplication table is learned predominantly by rote learning of reciting multiplication table (which is named Kuku) with a standardized mnemonic rhymes. The Kuku is memorized intensively by oral repetitions. Therefore, it is not clear whether the neuropsychological features of the
OBJECTIVE
To use the findings from neuropsychological evaluation and functional magnetic resonance imaging (fMRI) to assess interhemispheric reorganization of function after early unilateral brain injury.
METHODS
The study focused on one case of early brain injury that resulted in both dyscalculia
A patient with an intracranial hemorrhage showed differential impairment among arithmetic types (impaired in multiplication but not in subtraction). A functional magnetic resonance imaging (fMRI) experiment using normal volunteers also revealed a differential activation between the two arithmetic
We report a patient with phonological agraphia (selective impairment of kana [Japanese phonetic writing] nonwords) and acalculia (mental arithmetic difficulties) with impaired verbal short-term memory after a cerebral hemorrhage in the opercular part of the left precentral gyrus (Brodmann area 6)
This study, about 18 cases of AVA strictly in language areas (posterior end of the inferior frontal gyrus (Broca), posterior third of T1 and T2, supra-marginalis and angularis gyri), prepose to specify the possibilities and the legitimacy of surgical management as well as the technical parts of
We report a case of a 47-year-old man with anti-phospholipid antibody syndrome associated with subdural hematoma. The patient had several episodes of arthritis during his thirties. He developed venous thrombosis in his right lower leg at the age of 35, when laboratory studies demonstrated
The authors study the characteristics of a group of 23 patients for whom an initial tentative diagnosis of Hakim-Adams syndrome (H-A syndrome) was eventually rejected. On account of several factors distinguishing these patients from the true H-A group, the authors propose using the term "pseudo
In this paper, we describe the case of a right-handed man, MR, who after right thalamic haemorrhage presented subtranscortical aphasia. Of the disturbances generally associated with standard left hemisphere functions, the patient presented acalculia but not apraxia. Among the functions attributed to
We report clinical and pathological features of a case of dementia syndrome due to dural sinus thrombosis. In three years before admission, the patient, a 64-year old man, had had four convulsive attacks; scattered calcification shadows were disclosed by plain CT. Ten months before the admission, he
A 44-year-old farmer complained blurred vision and disturbance of recent memory. During his driving car traffic accident happened due to his right homonymous hemianopsia. On the 1st admission, neurological examination revealed choked disc(1 D.), hemianopsia, memory disturbance, dyscalculia, dyslexia
A case associated with multiple cerebral vascular anomalies, which consisted of fenestration of the middle cerebral artery, arteriovenous malformation and aneurysm of the anterior communicating artery, was reported. A 48 year-old male has been suffering from the left paralysis and mental disorder
OBJECTIVE
To unravel risk predictors for impaired numerical skills at 5 years of age in a population-based cohort of very preterm infants.
METHODS
Between January 2003 and August 2006, we prospectively enrolled all infants born in Tyrol with <32 weeks of gestation. A total of 161 of 223 preterm
