Only one percent of the global population is ambidextrous i.e., they have the ability to write with both the hands simultaneously. Leonardo da Vinci, Ben Franklin, Albert Einstein are some of the genius in history who are capable of writing with both their hands.
In India, there is an ambidextrous school where nearly 300 students are ambidextrous. They can write in high speed and utmost accuracy and most surprisingly they are able to write in six different languages like Hindi, English, Urdu, Sanskrit, Arabic and Roman.
But a question arises , ” Does Ambidextrousness improve the brain function and memory??”
Studies show that although teaching people to be ambidextrous is popular for centuries, this practice does not improve brain function, and it may even harm our neural development leading to dyslexia and dyscalculia, which are serious learning disabilities.
Research in Sweden found ambidextrous children to be at a greater risk for developmental conditions such as attention-deficit hyperactivity disorder. Another study revealed that these people performed worse than left or right-handers on a range of skills, especially in math, memory retrieval and logical reasoning. Also ambidextrous people are at a higher risk for schizophernia than the rest of the population (usually have the LRRTM1 gene which is linked with schizophrenia).
