A variety of platelet function tests were performed in patients with four forms of obstructive cerebrovascular disease (CVD); transient ischemic attacks (TIA), reversible ischemic neurological deficit (RIND), cerebral infarct, and cerebral embolism of cardiac source in rheumatic valvular heart disease (RVHD). Platelet studies included platelet aggregation induced by ADP and ristocetin, spontane...

OBJECTIVE Cerebral vessels, such as intracerebral perforating arterioles isolated from rat brain, have been widely used as an ex vivo model to study the cerebrovascular function associated with cerebrovascular disorders and the therapeutic effects of various pharmacological agents. These perforating arterioles, however, have demonstrated differences in the vascular architecture and reactivity c...

Asymmetric Dimethylarginine and Cerebrovascular Disorders in Humans To the Editor: We read with great interest the recent article by Dr Kielstein and colleagues1 dealing with the cerebrovascular effects of the endogenous nitric oxide (NO) synthase inhibitor, asymmetric dimethylarginine (ADMA), in humans. The results of their study demonstrated that systemic infusion of ADMA increased arterial s...

Sickle Cell Disease (SCD) is one of the most common severe monogenic disorders worldwide. Cerebrovascular complications, mainly stroke and silent infarcts deeply impact the health of children with SCD. Cognitive impairment and poor academic performances can also affect the quality of life. This chapter reviews the approach to cerebrovascular complication and cognition in different countries and...

Cerebellar circuitry is important to controlling and modifying motor activity. It conducts the coordination and correction of errors in muscle contractions during active movements. Therefore, cerebrovascular lesions of the cerebellum or its pathways can cause diverse movement disorders, such as action tremor, Holmes' tremor, palatal tremor, asterixis, and dystonia. The pathophysiology of abnorm...

Evidence increasingly suggests sleep disorders are associated with higher risk of cardiovascular events, including stroke. Strong data correlate untreated sleep apnea with poorer stroke outcomes and more recent evidence implicates sleep disruption as a possible etiology for increased cerebrovascular events. Also, sleep duration may affect incidence of cardiovascular events. In addition, sleep-d...
