Learning disabilities are neurocognitive disorders that impair learning. In many cases learning disabilities can be overcome by nontraditional methods which are often not within the expertise of most teachers.
Psychologists often define learning disabilities as “specific learning disorders”. Research has indicated that specific learning disabilities may be a single disability or there may be several disabilities present simultaneously. I choose to separate specific learning disorders into focused areas of learning deficiencies in reading, handwriting, numeracy, and executive functions.
All these areas can and should be identified through psychological testing which considers a broad range of factors including IQ, educational opportunities, motivation, and other sensory factors. However, to remediate these learning disabilities, each disorder must be specifically assessed. Therefore, I follow more specific definitions of these specific learning disabilities as dyslexia, dysgraphia, dyscalculia, and ADHD. The disorders will not be diagnosed in persons with average or above average intellectual abilities and who have not had adequate academic opportunities, or who are poorly motivated, or have any relevant sensory impairments.
Dyslexia, like other learning disabilities, is a neurocognitive disorder that obstructs the normal psychological process of learning to read. The psychological process centers around a system in the brain called the phonological loop. In simple terms this means that a person with dyslexia cannot associate sounds with letters the way that most people do. Learning to read with traditional teaching methods is not possible and most teachers do not have the skills to assess and intervene effectively.
The International Dyslexia Association (IDA) says that the problems displayed by individuals with dyslexia involve difficulties in acquiring and using written language. It is a myth that individuals with dyslexia “read backwards,” although spelling can look quite jumbled at times because students have trouble remembering letter symbols for sounds and forming memories for words.
Not all students who have difficulties with these skills have dyslexia. Formal testing of reading, language, and writing skills is the only way to confirm a diagnosis of suspected dyslexia.(IDA)
Other problems experienced by people with dyslexia include the following:
Dysgraphia is related to dyslexia. Dysgraphia is an inability to connect the shape of a letter or words with the muscle movements in the hand and arm to write. In other words, a person with dysgraphia has very bad handwriting. Dysgraphia involves areas of the brain that are also involved with dyslexia, so these two disorders can be present simultaneously. However, dysgraphia involves other parts of the brain that coordinate physical movements that are not involved with dyslexia.
According to the Cleveland Clinic, People with dysgraphia may have several different difficulties when it comes to writing and may speak more easily and fluently than they write.
Having one of these signs doesn’t mean that a person has dysgraphia, but if your child is having trouble learning the basic skills for writing that are appropriate for their age, they should be tested to see if they need specific help. (Cleveland Clinic)
They may have issues with:
Specific ways dysgraphia can present include:
Dyscalculia is a neurocognitive disorder that prevents the learning of certain math skills, specifically arithmetic. It does not mean that a person is just bad at math. It is specifically related to the ability to do arithmetic which means it has longer-range effects on learning geometry and algebra. Like dysgraphia, dyscalculia shares some of the brain structure to function. Therefore, it too, may be present with dyslexia as well as dysgraphia.
The Cleveland Clinic provides age-related signs of dyscalculia as follows:
Young children (up to the pre-K and kindergarten levels)
For very young children, the most common symptoms include trouble with:
School-age children (primary/grade/elementary school)
The symptoms of dyscalculia often draw attention when children start school around age 6. For these children, the symptoms include trouble with:
Teenagers (secondary school- or high school-age) and adults
The symptoms in teenagers and adults often look like trouble with the following:
ADHD is a complicated diagnosis that involves executive functioning in the brain. Physicians as well as psychologists may be involved in the diagnosis and treatment of ADHD to provide therapies and medications for aspects of the disorder not directly related to learning. The learning aspects of ADHD are primarily associated with teaching methods that compensate for the level of distraction a student experiences. ADHD can be present with either or all of dyslexia, dysgraphia, and dyscalculia.
According to the Diagnostic and Statistical Manual of mental Disorders (DSM-5) 6 or more of the following characteristics must be present:
