When a person doesn’t choose a dominant side of the brain, he or she may have mixed dominance or cross laterality.   A balanced brain is one that has equal activation of both hemispheres, as well as a computational problem on the non-dominant side. A lack of a strong hand or side can increase the chance of having ADHD or other learning difficulties.
Many children experience mixed dominance and are oftentimes great athletes.  The condition is often confusing which is challenging to identify.  Many parents are unaware that their child has mixed dominance until they experience difficulties in school, particularly with attention, impulsiveness, slow processing speed, working memory, and sensory processing issues. This is why they are unable to complete executive functioning activities due to a lack of functional dominance in one side of the brain.

The Research

According to studies, individuals who are left-handed or ambidextrous may be at greater risk for a range of issues including dyslexia, ADHD, and other learning difficulties.

Children who are ambidextrous or do not have a dominant hand generally find it difficult to learn as readily and successfully as those that use only one side. Handedness, according to studies such as this essay by Dr. David Frawley, has a high correlation with ADHD symptoms in school, resulting in greater difficulties at home and in society.

When compared to left-handed and right-handed children, ambidextrous youngsters were more likely to have ADHD and language learning issues in a 2010 Pediatrics study.

The Challenges

Functional disconnection syndrome (FDS) is a condition in which the brain’s connections are disrupted. It may result from defective development during childhood, as well as from abnormal growth or injury in one hemisphere.  Children who are mixed dominant may believe their brain is operating more slowly. When individuals have a different dominant side for both eyes and hearing, the connections between them must hop across the inside of the skull, which might slow down cognitive performance.

Because there’s no second half to balance out neural activities linked with sensory input processing or proper executive functioning, which is in charge of attention, memory, and problem-solving abilities, neurological symptoms may appear.

The Good News

It wasn’t until recently that researchers and experts discovered a link between mixed dominance and ADHD or other developmental issues. Parents can swiftly put together the correct blend of resources and expert assistance to help their kids overcome learning challenges without falling behind their peer group by correctly identifying these difficulties.
