Learning Disabilities at a Glance
Learning disabilities are real. A person can be of average or above-average intelligence, not have any major sensory problems (like blindness or hearing impairment), and yet struggle to keep up with people of the same age in learning and regular functioning.
What is a learning disability?
A learning disability (LD) is a neurological disorder that affects the brains ability to receive, process, store and respond to information. The term learning disability is used to describe the seeming unexplained difficulty a person of at least average intelligence has in acquiring basic academic skills. These skills are essential for success at school and work, and for coping with life in general. LD is not a single disorder. It is a term that refers to a group of disorders.
How can one tell if a person has a learning disability?
Learning disabilities can affect a persons ability in the areas of:
Other features of a learning disability are:
- A distinct gap between the level of achievement that is expected and what is actually being achieved
- Difficulties that can become apparent in different ways with different people
- Difficulties that manifest themselves differently throughout development
- Difficulties with socio-emotional skills and behavior.
A learning disability is not a disease, so there is no cure, but there are ways to overcome the challenges it poses through identification and accommodation.
If there is reason to think a person might have LD, it is important to collect observations by parents, teachers, doctors and others regularly in contact with that person. If there does seem to be a pattern of trouble that is more than just an isolated case of difficulty, the next step is to seek help from school or consult a learning specialist for an evaluation.
Accommodation and Modification
Depending on the type of learning disability and its severity, as well as the persons age, different kinds of assistance can be provided. Under the Individuals with Disabilities Education Act (IDEA) of 1997 and Americans with Disabilities Act (ADA) of 1990 people of all ages with LD are protected against discrimination and have a right to different forms of assistance in the classroom and workplace.
What causes learning disabilities?
Experts arent exactly sure what causes learning disabilities. LD may be due to:
- Heredity often learning disabilities run in the family, so its not uncommon to find that people with LD have parents or other relatives with similar difficulties.
- Problems during pregnancy and birth LD may be caused by illness or injury during or before birth. It may also be caused by drug and alcohol use during pregnancy, low birth weight, lack of oxygen and premature or prolonged labor.
- Incidents after birth Head injuries, nutritional deprivation and exposure to toxic substances (i.e. lead) can contribute to LD.
Learning disabilities are NOT caused by economic disadvantage, environmental factors or cultural differences. In fact, there is frequently no apparent cause for LD.
Each type of strategy should be considered when planning instruction and support. A person with dysgraphia will benefit from help from both specialists and those who are closest to the person. Finding the most beneficial type of support is a process of trying different ideas and openly exchanging thoughts on what works best.
Are learning disabilities common?
Currently, almost 2.9 million school-aged children in the US are classified as having specific learning disabilities (SLD) and receive some kind of special education support. They are approximately 5% of all school-aged children in public schools. These numbers do not include children in private and religious schools or home-schooled children.
Studies show that learning disabilities do not fall evenly across racial and ethnic groups. For instance, in 2001, 1% of white children and 2.6% of non-hispanic black children were receiving LD-related special education services*. The same studies suggest that this has to do with economic status and not ethnic background. LD is not caused by economic disadvantage, but the increased risk of exposure to harmful toxins (lead, tobacco, alcohol, etc.) at early stages of development are prevalent in low-income communities.
What can one do about learning disabilities?
Learning disabilities are lifelong, and although they wont go away, they dont have to stop a person from achieving goals. Help is available if they are identified. Learning disabilities affect every person differently, and the disorder can range from mild to severe. Sometimes people have more than one learning disability. In addition, approximately one third of people with LD also have attention deficit hyperactivity disorder (AD/HD), which makes it difficult for them to concentrate, stay focused or manage their attention to specific tasks.
Learning Disorders Also called: Learning differences, Learning disabilities
Learning disorders affect how a person understands, remembers and responds to new information. People with learning disorders may have problems
- Listening or paying attention
- Reading or writing
- Doing math
Although learning disorders occur in very young children, they are usually not recognized until the child reaches school age. About one-third of children who have learning disabilities also have ADHD, which makes it hard to focus.
Evaluation and testing by a trained professional can help identify a learning disorder. The next step is special education, which involves helping your child in the areas where he or she needs the most help. Sometimes tutors or speech or language therapists also work with the children. Learning disorders do not go away, but strategies to work around them can make them less of a problem.
