What is a Learning Disability? (Max)

A learning disability is a neurological disorder. In simple terms, a learning disability results from a difference in the way a person's brain is "wired." Children with learning disabilities are as smart or smarter than their peers. But they may have difficulty reading, writing, spelling, reasoning, recalling and/or organizing information if left to figure things out by themselves or if taught in conventional ways.

A learning disability can't be cured or fixed; it is a lifelong issue. With the right support and intervention, however, children with learning disabilities can succeed in school and go on to successful, often distinguished careers later in life.

Parents can help children with learning disabilities achieve such success by encouraging their strengths, knowing their weaknesses, understanding the educational system, working with professionals and learning about strategies for dealing with specific difficulties.

Not all great minds think alike

Did you know that Albert Einstein couldn't read until he was nine? Walt Disney, General George Patton, and Vice President Nelson Rockefeller had trouble reading all their lives. Whoopi Goldberg and Charles

Schwab and many others have learning disabilities which haven't affected their ultimate success.

Facts about learning disabilities

 Fifteen percent of the U.S. population, or one in seven Americans, has some type of learning disability, according to the National Institutes of Health.

 Difficulty with basic reading and language skills are the most common learning disabilities. As many as 80% of students with learning disabilities have reading problems.

 Learning disabilities often run in families.

 Learning disabilities should not be confused with other disabilities such as mental retardation, autism, deafness, blindness, and behavioral disorders. None of these conditions are learning

 disabilities. In addition, they should not be confused with lack of educational opportunities like frequent changes of schools or attendance problems. Also, children who are learning English do not necessarily have a learning disability.

Attention disorders, such as Attention Deficit/Hyperactivity Disorder (ADHD) and learning disabilities often occur at the same time, but the two disorders are not the same.

Common learning disabilities

 Dyslexia – a language-based disability in which a person has trouble understanding written words.

It may also be referred to as reading disability or reading disorder.

 Dyscalculia – a mathematical disability in which a person has a difficult time solving arithmetic problems and grasping math concepts.

 Dysgraphia – a writing disability in which a person finds it hard to form letters or write within a defined space.

 Auditory and Visual Processing Disorders – sensory disabilities in which a person has difficulty understanding language despite normal hearing and vision.

 Nonverbal Learning Disabilities – a neurological disorder which originates in the right hemisphere of the brain, causing problems with visual-spatial, intuitive, organizational, evaluative and holistic processing

What is Morquio Syndrome? (Kevin, AKA “Freak”)

Morquio syndrome is an inherited disease of metabolism in which the body is missing or doesn't have enough of a substance needed to break down long chains of sugar molecules called glycosaminoglycans

The syndrome belongs to a group of diseases called mucopolysaccharidoses (MPS).

Specifically, it is known as MPS IV.

Causes

Morquio syndrome is an auto-somal recessive trait. That means both your parents must pass you the defective gene in order for you to get this disease.

There are two forms of Morquio syndrome: Type A and Type B.

Persons with Type A do not have a substance (enzyme) called galactosamine-6-sulfatase.

Persons with Type B do not produce enough of an enzyme called beta-galactosidase.

The body needs these enzymes to break down a long strand of sugar molecules called the keratan sulfate sugar chain. In both types, abnormally large amounts of glycosaminoglycans build up in the body and brain, which can damage organs.

The syndrome is estimated to occur in 1 of every 200,000 births. Symptoms usually start between ages 1 and 3.

A family history of the syndrome raises one's risk for the condition.

Symptoms

Coarse facial features

Large head

Knock-knees

Widely spaced teeth

Bell-shaped chest with ribs flared out at the bottom

Short stature with a particularly short trunk

Hypermobile joints

Abnormal development of bones, including the spine

Exams and Tests

The doctor will perform a physical examination. Examination and testing may reveal:

Abnormal curvature of the spine

Cloudy cornea

Heart murmur

Inguinal hernia

Liver enlargement

Loss of nerve function below the neck

Short stature (especially short trunk)

Urine tests are usually done first. These tests may show extra mucopolysaccharides, but they can't determine the specific form of MPS.

Other tests may include:

Blood culture

Echocardiogram

Genetic testing

Hearing test

Slit-lamp eye exam

Skin fibroblast culture

X-rays of the long bones, ribs, and spine

Persons with Morquio syndrome should have MRI of the lower skull and upper neck to determine if the upper vertebrae are underdeveloped.

Treatment

There is no specific treatment for Morquio syndrome. Symptoms are treated as they occur.

A spinal fusion may prevent irreversible spinal cord injury in persons whose neck bones are underdeveloped.

Outlook (Prognosis)

Cognitive function is usually normal in patients with Morquio syndrome.

Bone problems can lead to significant complications. For example, the small bones at the top of the neck may slip and damage the spinal cord, causing paralysis. Surgery to correct such problems should be done if possible.

Cardiac complications may lead to death.

Possible Complications

 Breathing problems

Heart failure

Spinal cord damage and possible paralysis

Vision problems

Walking problems related to abnormal curvature of the spine and other bone problems
