May is Williams Syndrome Awareness Month. It is a rare genetic condition that affects over 1 in 10,000 people worldwide. If you teach in a special needs classroom or work in an adult day habilitation program, it is likely you have experienced working and teaching a student or individual diagnosed with Williams Syndrome. Below you will find some interesting facts and statistics on the disorder:
It is a genetic condition that is present a birth.
It is a developmental disorder
Tend to have a mild or moderate intellectual disability.
It is also known as Beuren Syndrome and Williams-Beuren Syndrome.
The symptoms were first described by John C.P. Williams in 1961.
A year later, German Physician, A.J. Beuren described three new incidents of patients with similar facial features.
It is caused by the spontaneous deletion of 26-28 genes on Chromosome #7
The deletion is caused by either the sperm or the egg.
The deletion is present at the time of conception
The most common symptoms of Williams Syndrome includes unusual facial features and heart defects.
The diagnosis is typically confirmed after identifying facial features and genetic testing.
An individual with Williams Syndrome has a 50% chance of passing the disorder on to their children.
Williams Syndrome affects 1 in 10,000 people worldwide.
An estimated 20,000 to 30,000 people in the United States are affected.
It occurs in both males and females equally
It is found in every culture
Individuals with Williams Syndrome tend to be overly friendly.
People with Williams Syndrome often have difficulty with visual-spatial tasks
Congenital heart defects (CHD) occur in approximately 75 percent of children
By the age of 30, the majority of individuals with Williams Syndrome have pre-diabetes or diabetes.
Cerebral Palsy is defined as a group of disorders of movement and posture causing limitations due to abnormal development in the brain. According to the Centers for Disease Control and Prevention (CDC), many children and adults with cerebral palsy also had at least one co-occurring condition and in some cases more than one. for example, it is not unusual for and individual to have a diagnoses of cerebral palsy with a co-occurring condition of epilepsy and an intellectual disability and associative issues with an eating disorder.
Understanding both co-occurring conditions and associative disorders is essential in order to develop an effective teaching strategy.
associative issues include aspiration, dysphagia, digestive issues, seizures, intellectual disability, sleep disorder, and speech impairments.

March is Developmental Disabilities Awareness month! Although I blogged the definition of developmental disabilities here, I wanted to give you more information besides the Federal regulation. Quite often, people are confused between the definition of an intellectual disability and a developmental disability.
A developmental disability is described as an assortment of chronic conditions that are due to mental or physical impairments or both. For example, you may have a child or an adult with an intellectual disability or perhaps a person diagnosed with cerebral palsy and an intellectual disability. It is also considered a severe and chronic disability that can occur up to the age of 22, hence the word developmental. A developmental disability can occur before birth such as genetic disorders (i.e. cri du chat, fragile x syndrome,) or chromosomes ( i.e. Down syndrome, Edwards syndrome); during birth (lack of oxygen) or after birth up to the age of 22 (i.e. head injuries, child abuse or accidents).
The disability is likely to occur indefinitely meaning the person will require some type of ongoing service throughout their lives. Finally, the person must show limitations in 3 or more of the following areas of major life activities:
Self-care– brushing teeth, hand-washing and combing hair independently
Receptive and expressive language-ability to understand someone talking and to also be understood
Learning– ability to read and write with understanding
Mobilityability to move around without any assistance
Self-direction– time management, organization
Capacity for independent living– requiring no supervision
Economic self-sufficiency – having a job and purchasing what one needs
Here are some examples of a developmental disability:
Does everyone with a disability also have a developmental disability?
The answer is no. there are people with disabilities such as epilepsy and cerebral palsy simply have a disability based on the criteria listed above. However, many people with developmental disabilities quite often have a combination of disabilities. For example a child with autism may also have seizures and an intellectual disability or an adult may have cerebral palsy, intellectual disability and epilepsy. In addition there are many people in the spectrum of autism who also have ADHD and so forth.
So what’s the difference between an intellectual disability and a developmental disability?
A person with an intellectual disability falls under the category of a developmental disability meaning you can have an intellectual disability and a developmental disability. check here for the definition of an intellectual disability, you will see they are quite similar.

Today is International Angelman Syndrome Day. It is a day to bring awareness to this disorder.
Angelman Syndrome is a genetic disorder that affects the nervous system, characteristics that include developmental delays, intellectual disability, and speech impairments. Angelman syndrome generally go unnoticed until the age of 1 year. Children typically have a happy demeanor and have a fascination with water
