Ask a Neurologist. Get Answers to Your Neurology Questions.
Hi, I am an American Board Certified Neurologist and I am very glad to help you with your health concerns.
Symptoms of numbness and blurring of vision lasting for only few seconds is very less likely related to stroke or mini stroke. A stroke or mini stroke would last much much longer than this (several minutes to hours to days). If you are having a history of anxiety disorder or stress etc then these conditions could trigger these type of bried duration symptoms. Some times there may not be any obvious underlying health conditions present to explain these type of brief duration symptoms. One or otherway these brief duration symptoms do not appear to be related to stroke or ministrokes. You may however try to see a neurologist and get this investigated – but any serious conditions including stroke/mini stroke etc appear very less likely.
All the very best!
