Is dyslexia hereditary?
Dyslexia is a neurological disorder that has a hereditary component. This indicates that people can inherit this ailment from their parents, and it impacts the neurological system's performance (specifically, the parts of the brain responsible for learning to read). It's not uncommon for a dyslexic child to have a family member who also suffers from the condition. It's also not uncommon for a family to have two or more children with this type of learning problem.
Dyslexia is equivalent to any other mental aptitude or ability, despite the fact that it has a genetic component (or weakness). A child's susceptibility to acquiring dyslexia may or may not be inherited from her parents. Even if the child inherits the genetic susceptibility for dyslexia, the child may not suffer the typical dyslexia symptoms.
If an older relative left school before the problem was discovered, it may be difficult to tell if he has dyslexia. If you have relatives who "hated school," "dropped out," or left school early to join the military or find work, they may have been dyslexic. School may have become a very frustrating and unrewarding place for them if they hadn't received the right assistance. Unfortunately, very young poor readers generally grow up to remain poor readers as adults unless they receive the appropriate interventions early in life. The good news is that if dyslexic youngsters are given sufficient teaching, especially in the early grades, they are more likely to have fewer or milder issues later in life.
Dyslexia is a condition that runs in families. It appears to be linked to genes that alter how the brain interprets reading and language, as well as environmental risk factors.
According to researchers who investigated identical twins, when one twin is dyslexic, the other is dyslexic 55 to 70% of the time, depending on the type of dyslexia. This study found that while there is a considerable genetic influence, the environment and life experiences also play a role in symptom development. Dyslexia is more likely caused by a combination of hereditary features rather than a single gene. Because of the mediating or boosting influence of other genes, the qualities may be displayed differently in different persons. As a result, a genetic test to identify dyslexia is unlikely to ever be developed. A person's DNA profile may, at best, assist in determining whether they have a higher chance of acquiring cancer.
Of course, if the child has a family history of dyslexia, this is important information to consider when making educational decisions, especially if the child appears to be struggling or frustrated in the early years of school.
