Asymmetric and Upper Body Parkinsonism in Patients with Idiopathic Normal-Pressure Hydrocephalus.

Background And Purpose: Our aims were to analyze the characteristics of parkinsonian features and to characterize changes in parkinsonian motor symptoms before and after the cerebrospinal fluid tap test (CSFTT) in idiopathic normal-pressure hydrocephalus (INPH) patients.

Methods: INPH subjects were selected in consecutive order from a prospectively enrolled INPH registry. Fifty-five INPH patients (37 males) having a positive response to the CSFTT constituted the final sample for analysis.

Impact of immediate post-reperfusion cooling on outcome in patients with acute stroke and substantial ischemic changes.

Background: In patients with acute stroke and an extensive ischemic burden at baseline, the prognosis is usually poor despite timely reperfusion.

Objective: To overcome universally poor outcomes in such patients, by applying immediate 'post-reperfusion cooling' in order to reduce reperfusion-related complications, and to describe the clinical and imaging characteristics.

Methods: Patients having (1) an acute anterior large vessel occlusive stroke within 4.

Forced arterial suction thrombectomy of septic embolic middle cerebral artery occlusion due to infective endocarditis: an illustrative case and review of the literature.

In acute ischemic stroke patients with major intracranial vessel occlusion due to infective endocarditis, treatment modalities are not well established. A 40-year-old woman presented with acute stroke due to left middle cerebral artery occlusion. She was successfully treated with intra-arterial mechanical thrombectomy, and the subsequent clinical outcome was favorable.

Posterior reversible encephalopathy syndrome due to hyponatremia.

Posterior reversible encephalopathy syndrome (PRES) is characterized by variable associations of seizure activity, consciousness impairment, headaches, visual abnormalities, nausea/vomiting, and focal neurological signs. The PRES may occur in diverse situations. The findings on neuroimaging in PRES are often symmetric and predominate edema in the white matter of the brain areas perfused by the posterior brain circulation, which is reversible when the underlying cause is treated.
