Stroke symptom recognition devices and methods

Abstract

Devices and methods for detecting one or more symptoms of stroke, such as motor function deficits and cognitive function deficits. By way of example, not limitation, the present invention provides devices and methods for detecting various forms of hemiparesis, ataxia, aphasia, and / or dysarthria, which may be measured alone or in any combination.

Description

CROSS-REFERENCE TO RELATED CASES [0001] The present application is a continuation of and claims priority to U.S. patent application Ser. No. 10 / 641,833 filed Aug. 15, 2003 entitled STROKE SYMPTOM RECOGNITION DEVICES AND METHODS, which claims the benefit of U.S. Provisional Patent Application No. 60 / 407,370 filed Aug. 31, 2002, entitled STROKE DETECTION DEVICE AND METHOD, U.S. Provisional Patent Application No. 60 / 429,101 filed Nov. 26, 2002, entitled STROKE DETECTION DEVICE AND METHOD, and U.S. Provisional Patent Application No. 60 / 460,525 filed Apr. 4, 2003, entitled STROKE SYMPTOM RECOGNITION DEVICE AND METHOD.FIELD OF THE INVENTION [0002] The present invention generally relates to medical diagnostic devices and methods. More specifically, the present invention relates to medical devices and methods for diagnosing symptoms of stroke.

AI Technical Summary

Benefits of technology

[0014] Thus, with the devices and methods of the present invention, a stroke victim is better able to ascertain symptoms associated with the onset of stroke, and more quickly seek medical attention, thereby reducing the time for implementation of time sensitive therapies (e.g., thrombolytic therapy) and improving the patient's long term outcome.

Problems solved by technology

Stroke is a leading cause of death and disability in industrialized nations.

Common symptoms include muscle weakness, numbness, paralysis, vision problems, loss of balance, loss of coordination, and speech impairment.

These symptoms are often subjective, and often not easily discernable by the user.

Therefore, people suffering from stroke are often not aggressive and inherently reluctant in seeking medical attention.

But, the effectiveness of this treatment drops off rapidly after the first hours following stroke.

Moreover, after 3 hours of symptom onset, use of thrombolytics dramatically increases the risk of hemorrhaging, substantially worsening the outlook for the user.

The primary cause of this delay is the delay in the user deciding to seek medical attention.
