Austrian Polyintervention Study to Prevent Cognitive Decline After Ischemic Stroke

2014-08-27 03:14:12 | BioPortfolio

Summary

Aim of this randomized controlled study is to test if intensive polyintervention therapy including life style modifications targeting at reduction of modifiable risk factors of stroke can reduce the risk of post-stroke cognitive decline compared to a group of patients receiving standard care.

Description

Stroke is the second most frequent cause of death and cognitive deficits including dementia occur frequently following a stroke. The frequency of cognitive disturbances has been reported up to 30% and thus occurs three times more frequent than recurrent stroke (10%). Major attempts have been made to prevent the occurrence of new strokes by means of effective strategies including preventive drugs. In contrast, hardly any studies have been performed addressing the prevention of deteriorating cognitive function following a stroke. In spite of this high prevalence therapeutic possibilities are extremely limited. It must be expected that cognitive deficits become even a more frequent disability following stroke. This is caused by the increased aging of the population leading to further increase of incidence, furthermore that more people survive their acute stroke due to increased possibilities of acute treatment, and that frequent risk factors (e.g. hypertension, diabetes) are increasingly controlled, thus leading to less severe strokes with less severe and permanent motor deficits, but an increase of potentially disabling cognitive disturbances. The aim of this randomized controlled study is to test an intensive multiple intervention therapy for the first time in stroke and to add life style modifications targeting modifiable risk factors for cognitive deterioration.

It is hypothesized that the risk of post-stroke cognitive decline can be significantly reduced compared to a control group with standard care when using polyintervention. These interventions will focus on nutrition, exercise, cognitive and social activity and monitoring and management of metabolic and vascular risk factors. Regular contacts with the subjects shall increase motivation and adherence to the study protocol.

Medical and Biotech [MESH] Definitions

The application of repeated, brief periods of vascular occlusion at the onset of REPERFUSION to reduce REPERFUSION INJURY that follows a prolonged ischemic event. The techniques are similar to ISCHEMIC PRECONDITIONING but the time of application is after the ischemic event instead of before.

A drug combination of aspirin and dipyridamole that functions as a PLATELET AGGREGATION INHIBITOR, used to prevent THROMBOSIS and STROKE in TRANSIENT ISCHEMIC ATTACK patients.

Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy. (Glaser, Neuro-Ophthalmology, 2nd ed, p135)

Restoration of functions to the maximum degree possible in a person or persons suffering from a stroke.

Restoration of blood supply to tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. It is primarily a procedure for treating infarction or other ischemia, by enabling viable ischemic tissue to recover, thus limiting further necrosis. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing REPERFUSION INJURY.
