Strokesaffect different parts of the brain depending on where the blood flow disruption occurs.
This article reviews the main differences between strokes in people that are right-handed vs. people that are left-handed.
Most people also have a hand preference in sports such as tennis, baseball, and football.

About 10% of the population is born left-handed.
Believe it or not this revelation is less than 70 years old.
The other 30% of left-handed patients process language on the right or in both hemispheres.
There are several regions in the brain that work together to control language function.
Stroke and Right-Handedness or Left-Handedness
Neurologistsusually ask if you are right-handed or left-handed during a neurological evaluation.
This is a much more subtle function called visual spatial perception.
Visual spatial perception is controlled by a region in your brain located in the non-dominant hemisphere.
However, a non-dominant stroke can still have a significant effect.
A Word From Verywell
Your whole brain works together as a highly sophisticated machine.
The functions of language and spatial perception are each highly concentrated on opposite sides of the brain.
Interestingly, your left- or right-hand dominance reflects the organization of your brain.
