A simple test for stroke detection was described here in the U.S. recently. Doctors described three things to do to recognize someone who has experienced stroke:
1. As the person to "see their teeth"... in other words, smile. Stroke victims cannot smile in a coordinated way and one side of the face always droops.
2. Ask the person to close their eyes and raise both arms straight in front of them. again, stroke victims cannot raise botha rms equally level.
3. Lastly, the suspected victim was asked to repeat simple sentence, such as, "Don't cry over spilt milk". Stroke victims can't cope with the multi-syllables.
97% of untrained individuals were able to accurately detect stroke in victims using these simple tests.
The confusion can be the result of senile dementia, but the symptoms of that malady are usually diagnosed well before a sudden onset.
