Introduction: Progressive multifocal leukoencephalopathy is a disorder which is rare in immunocompetent patients.
Objectives: We report the cases of two elderly patients with serology, in one case positive for hepatitis C, and in the other with anti-DNA antibodies, and discuss the part these might play in causing progressive multifocal leukoencephalopathy.
Clinical Cases: Case 1.
Cognitive deficits and psychiatric manifestations such as depression and psychosis have been associated with obstructive sleep apnea (OSA) syndrome. We report a patient with OSA admitted to our center because of acute delirium of sudden onset at night, during sleep, and which impelled the patient to jump out of the window of his home. After exhaustive study, no other causes were found for the delirium, which resolved when nasal continuous positive airway pressure (nCPAP) was initiated.

However, few studies have been done to evaluate its role in follow-up in this cerebrovascular disorder.
Objective: To assess the alterations in resonance signal in follow-up of patients with thrombosis of the dural sinuses and the clinical correlation of this.
Background And Purpose: The aims of this prospective and multicenter study were to determine the frequency of anticardiolipin and antinuclear antibodies in an unselected ischemic and hemorrhagic stroke population and to evaluate the clinical significance of these autoantibodies.
Methods: Over a 1-year period, we collected plasma from 481 consecutive patients with ischemic or hemorrhagic stroke attending four different hospitals. Blood (10 mL) was drawn from each subject into a citrated glass tube.
