The abilities of children diagnosed with developmental dyscalculia (DD) were examined in two types of object enumeration: subitizing, and small estimation (5-9 dots). Subitizing is usually defined as a fast and accurate assessment of a number of small dots (range 1 to 4 dots), and estimation is an
Developmental dyscalculia (DD) is a pervasive difficulty affecting number processing and arithmetic. It is encountered in around 6% of school-aged children. While previous studies have mainly focused on general cognitive functions, the present paper aims to further investigate the hypothesis of a
Higher cerebral dysfunctions such as aphasia, apraxia and agnosia have seldom been reported in multiple sclerosis (MS). 12 year-old right-handed boy felt unsteadiness of the body and headache for several days. Two months later, he had the same episode and complained of visual disturbance, and
BACKGROUND
Dementia with Lewy bodies is the second commonest type of dementia. The latest criteria for its diagnosis have recently been established (1996).
METHODS
We report the clinical findings in 25 patients with probable dementia with Lewy bodies.
RESULTS
No sex predominance was seen, onset was
A 51-year-old man developed muscle weakness of the bilateral upper extremities, and mental changes beginning with personality change. There was no history of mental illness in his family. A neurological examination 1 year after the onset revealed muscle atrophy and fasciculation of his bilateral
It is not unusual to observe hemichorea in patients with diabetes mellitus, with origins attributable to recent ischemia. Our patient was a 66-year-old female with diabetes mellitus who suddenly developed right hemichorea, mild muscle weakness of the right upper extremity, ideational apraxia, and
Twenty-four patients presenting an acute stroke with watershed cerebral infarct on CT scan or MRI were included in this retrospective study. Age was 63 +/- 14 years (mean +/- SD), and sex ratio was 2 men for 1 woman. Main clinical features were: in anterior location, lower limb weakness and frontal
We examined a patient who had signs of a cerebral hemisphere lesion: right hemiparesis, facial weakness, right hemianopsy, acustico-mnestic dysphasia, "empty speech," acalculia, visuo-spatial agnosia and constructional apraxia, but without changes in consciousness. Taking into account clinical
To assess the safety of human papilloma virus (HPV) vaccines by using data from the "Nagoya City Cervical Cancer Immunization Program Survey".Unadjusted odds ratios (OR) were calculated between HPV-vaccinated cases and un-vaccinated controls. A 65-year-old right-handed man noted a sudden onset of numbness and weakness of the right hand. On the initial visit to our hospital, he showed severe acalculia, and transient agraphia (so called incomplete Gerstmann syndrome) and transcortical sensory aphasia. Brain MRI revealed a fresh infarct in
We report a patient who exhibited Gerstmann's syndrome in association with a chronic subdural haematoma. A 71-year-old right-handed woman presented with mild right arm and leg weakness that began 2 weeks prior to admission. Neurological examination on admission revealed a mild right hemiparesis.
A 29-year-old immunocompetent woman was admitted in 2006 with ataxia, limb weakness, generalized dystonia, and vertical diplopia that developed after a febrile episode. Brain magnetic resonance imaging (MRI) revealed the presence of extensive periventricular white matter lesions that did not enhance
The study of 3 personal cases and 5 published cases of unilateral infarct limited to the territory of the tuberothalamic artery suggests that this syndrome should be differentiated from the other thalamic syndromes. The onset is usually sudden, with moderate contralateral weakness. Sensory changes
Inclusion body myopathy associated with Paget's disease of bone and frontotemporal dementia (IBMPFD) is a progressive, fatal genetic disorder with variable penetrance, predominantly affecting three main tissue types: muscle (IBM), bone (PDB), and brain (FTD). IBMPFD is caused by mutations in the
Dyscalculia, dyslexia, and specific language impairment (SLI) are relatively specific developmental learning disabilities in math, reading, and oral language, respectively, that occur in the context of average intellectual capacity and adequate environmental opportunities. Past research has been
