Facts and Statistics- Obsessive Compulsive Disorder (OCD)

Obsessive- Compulsive Disorder (OCD) is defined as a disorder that includes two core symptoms- obsessions and compulsions. According to the Census for Disease Control and Prevention (CDC), obsessions are defined by:

  • Thoughts, impulses, or images that occur over and over again. These thoughts, impulses or images are unwanted. They cause a lot of anxiety and stress.
  • The person who has these thoughts, impulses or images tries to ignore them or tries to make them go away.

Compulsions are defined as:

  • Repeated behaviors or thoughts over and over again or according to certain rules that must be followed exactly in order to make an obsession go away.
  • The person feels that the purpose of the behaviors or thoughts is to prevent or reduce distress or prevent some feared event or situation.

The following are facts and statistics on Obsessive Compulsive Disorder:

  • 1.2% of U.S. adults had OCD in the past year.
  • OCD was higher for females (1.8%) than males (0.5%).
  • Among adults with OCD, approximately one half (50.6%) had serious impairment
  • 34.8% of adults with OCD had moderate impairment
  • 14.6% had mild impairment.
  • OCD affects 2.2 million adults
  • The average onset is 19 with 25% of cases occurring by age 14
  • One-third of affected adults first experience symptoms in childhood
  •  17% of autistic people may specifically have OCD
  • Because of similar characteristics, it is often overlooked
  • It affects people of all races, ethnicities, and socioeconomic backgrounds
  • OCD is one of the top 20 causes of illness-related disability worldwide for individuals between 15 and 44 years of age
  • 1 in 40 adults are affected.
  • 1 in 100 children are affected
  • Other conditions may co-exist with OCD including anxiety, bipolar, ADHD, autism spectrum, Tourette syndrome, and major depressive disorder.
  • Worldwide, OCD is approximately 2% of the general population
  • OCD ranks 10th place among all diseases
  •  1 in every 200 children has the disorder 60 to 70% of OCD children improve significantly with therapy.

Facts and Statistics- Ataxia

Ataxia is a rare disorder that affects both children and adults. I was quite surprise to find that very little statistics have been conducted on ataxia. this may be due to the understanding that Ataxia is not a specific disorder, rather, a condition can cause ataxia including multiple sclerosis, head trauma, cerebral palsy and infections.

Ataxia affects a child’s coordination, balance and speech while some children are born with ataxia as a result of genetics, others develop it in a progressive matter. Signs and symptoms of Acute Cerebellar Ataxia include:

  • Frequent stumbling
  • Impaired coordination affecting arms or legs
  • Unsteady gait
  • Uncontrolled eye movement
  • Difficulty performing fine motor task
  • headaches

The following are facts and statistics on the Ataxia disorder:

  • It is a degenerative disease of the nervous system
  • Symptoms, often mimic being drunk in adults such as slurred speech
  • Age of symptom can vary from childhood to late adulthood
  • rare recessive genetic disorder
  • occurs between 1 out of 40,000 and 1 out of 100,000
  • The word ataxia refers to clumsiness or a loss of balance and coordination
  • The ataxia gene was first identified in 1993
  • Ataxia is inherited
  • Ataxia is a sign of an underlying disorder
  • It is caused by damage to different areas of the central nervous system
  • The most common symptom in children is an unsteady gait
  • In some cases, ataxia can present itself rapid while in others, it is progressive.
  • The most common cause of acute ataxia in children are excessive drug ingestion and drug intoxications
  • There are from 50 to 100 different types of Ataxia.

15 Facts About Cri Du Chat Syndrome

Cri-Du Chat (cat’s cry) is a rare genetic disorder that results when a piece of the 5p chromosome is deleted. The name is French for “cry of the cat,” referring to the high-pitched cat-life cry. Other characteristics include intellectual disability, hyperactivity, and delay development. below are some more facts on this rare disease.

  • The syndrome gets its name from the infant cry which is similar to a meowing kitten
  • The cry is due to issues with the larynx and nervous system
  • About one third of children lose the cry by the age of 2 years.

  • It is more common in females by a 4.3 ratio
  • It is a rare genetic disorder
  • In some cases, cri du chat syndrome may go undiagnosed

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:

Autism Facts and Statistics

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder that impacts social, speech, behavioral and motor skills. It is a spectrum disorder meaning it varies from person to person. No two people have the same symptoms. It is estimated that 1% of the population is diagnosed with autism.

Prevalence

About 1 in 40 children has been identified with autism spectrum disorder (ASD).

1 in 42 boys are diagnosed with autism

1 in 189 girls are diagnosed with autism

100 individuals are diagnosed everyday

ASD is reported to occur in all racial, ethnic and socioeconomic groups.

ASD is 4 times more common among boys than girls.

Studies in Asia, Europe, and North American have idendified individuals with ASD  with an average prevalence of between 1% and 2%.

About 1 in 6 children diagnosed with autism also have a developmental disability.

Parents who have a child with ASD have a 2%-18% chance of having a second child diagnosed with autism

Almost half (44%) of children diagnosed with ASD has average to above average intellectual ability.

ASD commonly co-occurs with other developmental, psychiatric, neurological, chromosomal and genetic diagnoses.

Facts

Children and adults with Autism have significant problems in socializing with others, emotions, intense preoccupation with one or two topics, repetitive routines and motor skills.

Tend to be sensitive to sensations of sound, light or touch.

It is a common myth that autistic children can perform amazing skills such as memorizing birthdays and telephone numbers.

30% of autistic children have a seizure disorder

40% of children with autism do not speak

25-30% of children with autism have some words at 12 to 18 months, and then lose them.

Between 60% and 80% of children with ASD have a sleep-related disorder

Females tend to be more likely to show accompany intellectual disabilities.

Studies show that parents notice a developmental problem before the child’s first birthday

Lorna Wing, a psychiatrist and mother of a child with autism termed the word Autism Spectrum to describe a concept of complexities rather than a straight line from severe to mild.

Victor Lotter was the first person to  measure the prevalence of autism in a population.

Stimming

  • It is also prevalent among people on the autism spectrum.
  • In fact in many cases, it is part of the diagnosis due to the repetition of stimming.
  • Stimming is often used as a means to self-regulate, self-calm and for self-expression.
  • The movements are repetitive and are used to self-stimulate the 7 senses.
  • It is often described as a repetitive motor behavior that can disrupt academic and social and other activities.
  • One of the theories behind stimming is that beta-endorphrins are released in the brain casuing an euphoric feeling which is generally a response to pain.
  • Stimming behavior. based for self-soothing and to help a child or an adult regain emotional balance.
  • Sensory Overload. Too much sensory information can lead to stress, anxiety and eventually a meltdown.

Wandering Statistics

  • Nearly half of children with autism engage in wandering behavior
  • Increased risks are associated with autism severity
  • More than one third of children with autism who wander/elope are never or rarely able to communicate their name, address, or phone number
  • Half of families report they have never received advice or guidance about elopement from a professional
  • Accidental drowning accounts for 71% of lethal outcomes, followed by traffic injuries at 18%
  • Other dangers include dehydration; heat stroke; hypothermia; falls; physical restraint; encounters with strangers
  • Accidental drowning accounted for 91% total U.S. deaths reported in children with autism due to wandering.
