Malfunction in a brain
Differentialities in the brains of persons with the disability Dyslexia have been discovered through brain imaging investigations. According to the International Dyslexia Association, these anomalies are discovered in the area of the brain that deals with reading skills.
According to Dr. Davis, dyslexia is caused by a malfunction in a brain circuit that promotes reading. She claims that this circuit is made up of regions in the temporal and frontal lobes of the left hemisphere of the brain. These are the parts of the brain that deal with language comprehension and expression.
Causes for Dyslexia
According to the National Institute of Neurological Disorders and Stroke, dyslexia is also thought to run in families. If you or a family member has dyslexia, there's a chance your child will, too, though it's far from certain. In addition to having a family history of dyslexia, people who were born prematurely or with a low birth weight have a higher risk of developing it. While in the womb, exposure to alcohol, drugs, or illnesses can all increase the risk. The following are some of the causes of dyslexia:
- Dyslexia or other learning difficulties in the family
- Low birth weight or premature birth
- Nicotine, drugs, alcohol, or virus exposure during pregnancy may affect the fetus's brain development
- Individual distinctions in the areas of the brain that allow you to read
It's caused by a genetic mutation, which is why it commonly runs in families. If your parents, siblings, or other family members have dyslexia, you're more likely to have it as well.
- Differences in the areas of the brain that process language cause the disorder. In persons with dyslexia, imaging tests reveal that parts of the brain that should be engaged when reading isn't.
- 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.
- The causes of dyslexia differ depending on the type. Much of the study into primary dyslexia focuses on inherited causes. Specific genes have recently been identified as possibly contributing to the signs and symptoms of dyslexia, according to researchers. This study is critical because it could help identify children who are at risk of developing dyslexia, allowing for earlier educational interventions and better outcomes.
Occasionally, this is simply childhood dyslexia that isn't recognized until much later. However, the same symptoms can appear as a result of a brain injury or dementia. In fact, according to a 2012 study from the University of Dundee, the natural process of aging causes us to become moderately dyslexic as we get older.
Early exposure to stressful situations may be a cause of dyslexia, according to a new school of thinking in evolutionary developmental biology and research on the neuroscience of stress.
Trauma dyslexia is a type of dyslexia that happens when the part of the brain that regulates reading and writing is injured or damaged. In today's school-aged population, it is uncommon.
