Disorders

Asperger's syndrome, also called Asperger's disorder, is a type ofpervasive developmental disorder (PDD). PDDs are a group of conditions that involve delays in the development of many basic skills, most notably the ability to socialize with others, to communicate, and to use imagination. There is a spectrum within the PDD disorders.

Although Asperger's syndrome is similar in some ways to autism -- another, more severe type of PDD -- there are some important differences. Children with Asperger's syndrome typically function better than do those with autism. In addition, children with Asperger's syndrome generally have normal intelligence and near-normallanguage development, although they may develop problems communicating as they get older.

Asperger's syndrome was named for the Austrian doctor, Hans Asperger, who first described the disorder in 1944. However, Asperger's syndrome was not recognized as a unique disorder until much later.

What is Attention Deficit Hyperactivity Disorder (ADHD, ADD)?

Attention deficit hyperactivity disorder (ADHD) is one of the most common childhood disorders and can continue through adolescence and adulthood. Symptoms include difficulty staying focused and paying attention, difficulty controlling behavior, and hyperactivity (over-activity).

ADHD has three subtypes:

• Predominantly hyperactive-impulsive
  • Most symptoms (six or more) are in the hyperactivity-impulsivity categories.
  • Fewer than six symptoms of inattention are present, although inattention may still be present to some degree.

• Predominantly inattentive
  • The majority of symptoms (six or more) are in the inattention category and fewer than six symptoms of hyperactivity-impulsivity are present, although hyperactivity-impulsivity may still be present to some degree.
  • Children with this subtype are less likely to act out or have difficulties getting along with other children. They may sit quietly, but they are not paying attention to what they are doing. Therefore, the child may be overlooked, and parents and teachers may not notice that he or she has ADHD.

• Combined hyperactive-impulsive and inattentive
  • Six or more symptoms of inattention and six or more symptoms of hyperactivity-impulsivity are present.
  • Most children have the combined type of ADHD.

Signs & Symptoms

Inattention, hyperactivity, and impulsivity are the key behaviors of ADHD. It is normal for all children to be inattentive, hyperactive, or impulsive sometimes, but for children with ADHD, these behaviors are more severe and occur more often. To be diagnosed with the disorder, a child must have symptoms for 6 or more months and to a degree that is greater than other children of the same age.

Children who have symptoms of inattention may:

• Be easily distracted, miss details, forget things, and frequently switch from one activity to another
• Have difficulty focusing on one thing
• Become bored with a task after only a few minutes, unless they are doing something enjoyable
• Have difficulty focusing attention on organizing and completing a task or learning something new
• Have trouble completing or turning in homework assignments, often losing things (e.g., pencils, toys, assignments) needed to complete tasks or activities
• Not seem to listen when spoken to
• Daydream, become easily confused, and move slowly
• Have difficulty processing information as quickly and accurately as others
• Struggle to follow instructions.

Children who have symptoms of hyperactivity may:

• Fidget and squirm in their seats
• Talk nonstop
• Dash around, touching or playing with anything and everything in sight
• Have trouble sitting still during dinner, school, and story time
• Be constantly in motion
• Have difficulty doing quiet tasks or activities.

Children who have symptoms of impulsivity may:

• Be very impatient
• Blurt out inappropriate comments, show their emotions without restraint, and act without regard for consequences
• Have difficulty waiting for things they want or waiting their turns in games
• Often interrupt conversations or others' activities.

ADHD Can Be Mistaken for Other Problems

Parents and teachers can miss the fact that children with symptoms of inattention have the disorder because they are often quiet and less likely to act out. They may sit quietly, seeming to work, but they are often not paying attention to what they are doing. They may get along well with other children, compared with those with the other subtypes, who tend to have social problems. But children with the inattentive kind of ADHD are not the only ones whose disorders can be missed. For example, adults may think that children with the hyperactive and impulsive subtypes just have emotional or disciplinary problems.

What Is Autism? What is Autism Spectrum Disorder?

 Autism spectrum disorder (ASD) and autism are both general terms for a group of complex disorders of brain development. These disorders are characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors. With the May 2013 publication of the DSM-5 diagnostic manual, all autism disorders were merged into one umbrella diagnosis of ASD. Previously, they were recognized as distinct subtypes, including autistic disorder, childhood disintegrative disorder, pervasive developmental disorder-not otherwise specified (PDD-NOS) and Asperger syndrome. 

ASD can be associated with intellectual disability, difficulties in motor coordination and attention and physical health issues such as sleep and gastrointestinal disturbances. Some persons with ASD excel in visual skills, music, math and art.

Autism appears to have its roots in very early brain development. However, the most obvious signs of autism and symptoms of autism tend to emerge between 2 and 3 years of age. Autism Speaks continues to fund research on effective methods for earlier diagnosis, as early intervention with proven behavioral therapies can improve outcomes. Increasing autism awareness is a key aspect of this work and one in which our families and volunteers play an invaluable role. Learn more …

How Common Is Autism?

Autism statistics from the U.S. Centers for Disease Control and Prevention (CDC) identify around 1 in 68 American children as on the autism spectrum–a ten-fold increase in prevalence in 40 years. Careful research shows that this increase is only partly explained by improved diagnosis and awareness. Studies also show that autism is four to five times more common among boys than girls. An estimated 1 out of 42 boys and 1 in 189 girls are diagnosed with autism in the United States.

ASD affects over 3 million individuals in the U.S. and tens of millions worldwide. Moreover, government autism statistics suggest that prevalence rates have increased 10 to 17 percent annually in recent years. There is no established explanation for this continuing increase, although improved diagnosis and environmental influences are two reasons often considered

Obsessive–compulsive disorder (OCD) is a mental disorder where people feel the need to check things repeatedly, performcertain routines repeatedly, or have certain thoughts repeatedly. People are unable to control either the thoughts or the activities. Common activities include hand washing, counting of things, and checking to see if a door is locked. Some may have difficulty throwing things out. These activities occur to such a degree that the person's daily life is negatively affected.^[1] Often they take up more than an hour a day.^[2] Most adults realize that the behaviors do not make sense.^[1] The condition is associated with tics, anxiety disorder, and an increased risk of suicide.^[2][3]

The cause is unknown.^[1] There appears to be some genetic components with both identical twins more often affected than both non-identical twins. Risk factors include a history of child abuse or other stress inducing event. Some cases have been documented to occur following infections. The diagnosis is based on the symptoms and requires ruling out other drug related or medical causes.^[2] Rating scales such as the Yale–Brown Obsessive Compulsive Scale can be used to assess the severity.^[4] Other disorders with similar symptoms include: anxiety disorder, major depressive disorder, eating disorders, tic disorders, and obsessive–compulsive personality disorder.^[2]

Treatment for OCD involves the use of behavioral therapy and sometimes selective serotonin reuptake inhibitors (SSRIs). The type of behavior therapy used involves increasing exposure to what causes the problems while not allowing the repetitive behavior to occur.^[5] Atypical antipsychotics such as quetiapine may be useful when used in addition to an SSRI in treatment-resistant cases but are associated with an increased risk of side effects.^[6] Without treatment the condition often lasts decades.^[2]

Obsessive–compulsive disorder affects about 2.3% of people at some point in their life.^[7] Rates during a given year are about 1.2% and it occurs worldwide.^[2] It is unusual for symptoms to begin after the age of thirty-five and half of people develop problems before twenty.^[1][2] Males and females are affected about equally.^[1] In English the phrase obsessive–compulsive is often used in an informal manner unrelated to OCD to describe someone who is excessively meticulous, perfectionistic, absorbed, or otherwise fixated.^[8]
