Restless legs syndrome (RLS) is a common sleep disorder. In 1995, clinical criteria for the diagnosis of RLS were defined. ⋯ RLS is a clinically pleomorphic syndrome, reflecting the contribution of multiple genetic and acquired factors in the pathogenesis of RLS.

To gain insight of the underlying mechanisms of astroglial response to Alzheimer's disease (AD), the level of glial fibrillary acidic protein (GFAP) in cerebrospinal fluid (CSF) from controls and AD subjects were immunochemically determined, and the correlation between that level and dementia severity of AD patients was evaluated. Means and SD of CSF levels of GFAP for the young control group (from 1 to 25 years, mean +/- SD 14.2 +/- 5.0, n = 13) adult control (from 26 to 55 years, 41.6 +/- 10.1, n = 9) and senescent control (older than 56 years, 65.4 +/- 8.0, n = 8) were 2.96 +/- 1.04, 2.80 +/- 1.46 and 3.99 +/- 1.55 ng/ml, respectively, and the CSF level of GFAP was not dependent on age (ANOVA, p = 0.17). ⋯ The CSF level of GFAP in the moderately to severely demented patients (MMSE /= 18, 6.85 +/- 5.76 ng/ml, n = 18; ANOVA, p < 0.05). These findings together with our previous report on an increase in the CSF level of apolipoprotein E suggest that degeneration and stimulation of astrocytes takes place concurrently in the AD brain.

It is generally believed that a homonymous defect of macular vision (HMV) is caused by a small lesion restricted to the occipital lobe tip and rarely results from ischemic stroke. The incidence of HMV was studied retrospectively in 54 patients with infarction of the posterior cerebral artery territory who underwent Goldmann's visual field test. ⋯ All had a relatively large infarction extending from the occipital lobe tip to the posterior part of the calcarine cortex and/or the neighboring subcortical regions. Stroke-induced HMV can be caused by a large lesion involving the occipital pole and may not be so rare as generally considered.

Though there have been many reports on poststroke seizures, there is still much we do not know about them. Using a large cohort of stroke patients we analyzed the characteristics of the seizure(s) and the rate and factors involved in seizure recurrence. ⋯ This study confirms that poststroke seizures are frequent and must be divided into 2 types: early-onset (
