What health problems do left-handed people have?
Left-handedness has been linked to increased risk of certain neurodevelopmental disorders like schizophrenia and ADHD. Mixed-handedness is even more strongly associated with ADHD. Most people’s brains have a dominant side. More symmetrical brains of mixed-handed people may explain the link to some neural disorders.
Do left-handed people have different brains?

Why Was ‘Left’ Considered Evil? The association of the directional left with evil is likely attributed to the dominance of right-handed people within a population, and consequently the awkwardness of motions made from the left side of the body.
Is Einstein left-handed?
But handedness has its roots in the brain—right-handed people have left-hemisphere-dominant brains and vice versa—and the lefties who claim Einstein weren’t all that far off. While he was certainly right-handed, autopsies suggest his brain didn’t reflect the typical left-side dominance in language and speech areas.
What is unique about left-handers?
Left-handers use the right side of the brain more. The human brain is cross-wired — its right half controls the left side of the body and vice versa. Hence, left-handers use their right side of the brain more than right-handed people do. Left-handers recover quicker after a stroke.
Are left-handed people more likely to be dyslexic?
