This study encompasses the maintenance and utilization of a repository of samples from patients with cerebrovascular disease and stroke. The types of tissue taken are blood, cerebrospinal fluid (CSF), tissue, and microdialysis samples. Future analysis of these samples can potentially help investigators to better categorize groups of patients, understand the underlying etiology of these pathologies, identify markers that are associated with favorable or poor outcomes, and track changes that occur during the natural course of the disease or with treatment. This is a prospective observational study which will use samples from such patients to create this library which can be used to explore these questions in the future.
Genetic and metabolic profiling has become an important means to evaluate various pathologies, their effects on patients, and their treatments. In regards to cerebrovascular disease and stroke, there are a number of hypotheses which have been proposed. The levels and types of various angiogenic factors in the blood and tissues have been proposed to be predictive of patient outcome after ischemic stroke and treatment for stroke. Likewise, genetic factors may predict outcome or response to various types of treatments.
The role of biological samples in furthering our understandings about cerebrovascular disease and treatment are well documented. Muscle microdialysis samples have confirmed the presence of sublethal ischemia during the induction of remote ischemic preconditioning. The effects of remote ischemic preconditioning on the coagulation profile, DNA methylation, and cell cycle gene expression of patients with aneurysmal subarachnoid hemorrhage have also been elucidated. Blood samples collected in patients with intracranial arterial stenosis have produced many insights. Inflammatory cell profiles in patient who receive encephaloduroarteriosynangiosis (EDAS) surgery have been characterized. Angiogenic factor measurements have been shown to predict the degree of neovascularization in patients post-EDAS. In patients with intracranial atherosclerosis, angiogenic factor profiles were found to strongly correlate with failure of medical management and poor outcomes.
It is clear that genetic and metabolic profiling are effective tools in evaluating the effects of cerebrovascular disease and their treatments. This study encompasses the maintenance and utilization of a repository of samples from patients with cerebrovascular disease and stroke. For every patient enrolled in the study, relevant patient information such as age, gender, diagnosis, medical history, family history, procedures/treatments received, radiological reports, and patient outcomes are recorded. This information is updated upon every follow-up during the study. The types of tissue taken are blood, cerebrospinal fluid (CSF), tissue, and microdialysis samples.
Future analysis of these samples can potentially help investigators to better categorize groups of patients, understand the underlying etiology of these pathologies, identify markers that are associated with favorable or poor outcomes, and track changes that occur during the natural course of the disease or with treatment. This repository serves as the groundwork to explore these questions in the future.

A calcium channel blockader with preferential cerebrovascular activity. It has marked cerebrovascular dilating effects and lowers blood pressure.
Diseases of the BASAL GANGLIA including the PUTAMEN; GLOBUS PALLIDUS; claustrum; AMYGDALA; and CAUDATE NUCLEUS. DYSKINESIAS (most notably involuntary movements and alterations of the rate of movement) represent the primary clinical manifestations of these disorders. Common etiologies include CEREBROVASCULAR DISORDERS; NEURODEGENERATIVE DISEASES; and CRANIOCEREBRAL TRAUMA.
A syndrome characterized by DYSARTHRIA, dysphagia, dysphonia, impairment of voluntary movements of tongue and facial muscles, and emotional lability. This condition is caused by diseases that affect the motor fibers that travel from the cerebral cortex to the lower BRAIN STEM (i.e., corticobulbar tracts); including MULTIPLE SCLEROSIS; MOTOR NEURON DISEASE; and CEREBROVASCULAR DISORDERS. (From Adams et al., Principles of Neurology, 6th ed, p489)
Disorders of the centrally located thalamus, which integrates a wide range of cortical and subcortical information. Manifestations include sensory loss, MOVEMENT DISORDERS; ATAXIA, pain syndromes, visual disorders, a variety of neuropsychological conditions, and COMA. Relatively common etiologies include CEREBROVASCULAR DISORDERS; CRANIOCEREBRAL TRAUMA; BRAIN NEOPLASMS; BRAIN HYPOXIA; INTRACRANIAL HEMORRHAGES; and infectious processes.
Severe or complete loss of motor function in the lower extremities and lower portions of the trunk. This condition is most often associated with SPINAL CORD DISEASES, although BRAIN DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; NEUROMUSCULAR DISEASES; and MUSCULAR DISEASES may also cause bilateral leg weakness.
