Non-ketotic hyperglycaemia presenting as epilepsia partialis continua.

Epilepsia partialis continua is a rare epileptic syndrome observed in patients with brain structural lesions and metabolic disorders. We report a patient with non-ketotic hyperglycaemia presenting as epilepsia partialis continua with reversible focal brain lesions. An 83-year-old woman visited our hospital due to sudden and repetitive left facial twitching lasting for two days.

Sleep disturbances and predictive factors in caregivers of patients with mild cognitive impairment and dementia.

Background And Purpose: We examined the characteristics of sleep disturbances and sleep patterns in the caregivers of patients with amnestic mild cognitive impairment (aMCI) and dementia.

Methods: We prospectively studied 132 patients (60 with aMCI and 72 with dementia) and their caregivers, and 52 noncaregiver controls. All caregivers and controls completed several sleep questionnaires, including the Pittsburgh Sleep Quality Index (PSQI).

Plaque rupture is a determinant of vascular events in carotid artery atherosclerotic disease: involvement of matrix metalloproteinases 2 and 9.

Background And Purpose: Unstable carotid atherosclerotic plaques are characterized by cap rupture, leading to thromboembolism and stroke. Matrix metalloproteinases (MMPs) have been implicated in the progression of atherosclerosis and plaque rupture. The aim of this study was to assess the relationship between the expressions of MMP-2 and MMP-9 and carotid plaque instability.

A case of herpes zoster ophthalmicus with isolated trochlear nerve involvement.

Background: Herpes zoster ophthalmicus (HZO) can involve the oculomotor nerve; however, isolated trochlear nerve palsy has rarely been reported.

Case Report: An 83-year-old man who suffered from HZO in the right frontal area and scalp subsequently developed vertical diplopia and severe pain. Cerebrospinal fluid examination and brain MRI revealed no abnormalities.

Executive dysfunction associated with stroke in the posterior cerebral artery territory.

Cognitive decline following posterior cerebral artery infarction (PCAI) is associated with lesions in the occipital lobe that extend into the parahippocampus or the splenium. We investigated patterns of neuropsychological deficits, including those causing executive dysfunction, associated with isolated lesions of the occipital lobe and with extensive lesions of the occipital lobe that extended into the splenium or the posterior ventral temporal lobes including the parahippocampus and fusiform gyrus. Eleven patients with unilateral PCAI involving the cerebral cortex and one patient with an occipital hemorrhage were selected for inclusion in this study.

Splenium or parahippocampus involvement and its relationship to cognitive decline in posterior cerebral artery infarction.

Although cognitive impairment after a posterior cerebral artery (PCA) infarct is frequently observed, the important functional areas associated with cognitive decline, other than the thalamus, have not been determined. We investigated the locus or loci that might induce cognitive decline after a PCA infarct. Forty-one patients with unilateral PCA infarctions involving only the occipital lobe or the occipital lobe plus other PCA areas were included.

Takayasu's disease presenting with atherothrombotic ischaemic stroke.

Takayasu's arteritis is a chronic inflammatory disease of the aorta and its main branches, and a well known cause of stroke. Pathogenesis of ischaemic stroke has been attributed to intracranial vasculitic involvement or emboli from either stenoocclusive extracranial vessels or cardiac disease such as aortic regurgitation. We present a patient with Takayasu's arteritis and recurrent cerebral infarctions associated with intracranial atherosclerosis.

Relationship between clinical course and Diffusion-weighted MRI findings in sporadic Creutzfeldt-Jakob Disease.

The aim of this study was to investigate the relationship between clinical course and diffusion-weighted MRI (DWI) findings in sporadic Creutzfeldt-Jakob Disease (sCJD). We reviewed clinical records and MRI examination in nine probable sCJD. According to hyperintense signal distribution on DWI, the patients were classified into two groups with cortical ribbon plus basal ganglia hyperintensity (6/9) and with only increased cortical signals (3/9).

Dissociative disturbance in Hangul-Hanja reading after a left posterior occipital lesion.

Since the Korean language has two distinct writing systems, phonogram (Hangul) and ideogram (Hanja: Chinese characters), alexia can present with dissociative disturbances in reading between the two systems. A 74-year-old right-handed man presented with a prominent reading impairment in Hangul with agraphia of both Hangul and Hanja after a left posterior occipital- parietal lesion. He could not recognize single syllable words and nonwords in Hangul, and visual errors were predominant in both Hanja reading and the Korean Boston Naming Test.
