And to the dumba*s that made a comment about ADD at 28 - you can develop it at any age, whether or not you are still being educated. You can get 4.0's and 99% test scores your whole life and then suddenly find yourself having extreme difficulty. Do some research before you assume you know what you're critizing.
You have to show symptoms of impulsivity or inattention before the age of 7 for a diagnosis of ADHD. While an adult can be diagnosed with ADHD the psychologist would have to do a retroactive diagnoses meaning that these symptons were there in childhood but never found out. A mental health professional is typically reluctant to do so with students who were invloved in formal education due to the fact that someone else should have picked them up. The issue of adult onset ADHD is a contraversial one right now, with some saying it can be that a person develops a new set they've never had before while another group saying it's not possible. Currently the DSM still lists this disorder in the subsection Disorders Usually First Diagnosed in Infancy, Childhood or Adolencence. And the APA has not recognized adult onset ADHD to be a valid disorder. The DSM is the publication that all mental disorders available for diagnostic are listed along with the minimum symptoms needed to meet such a diagnostic. Its published and revised by the American Psychology Association. If it's not listed in the DSM then it basically isn't considered valid science until it gets in there.
if you want to read about ADHD. (formerly called ADD)
Behavenet is not summarizing DSM-IV - it is commentating on some medical views on the condition. True DSM-IV on the condition if very vague. Also, the medical community has expanded its diagnostic capability to combine the ADD/ADHD definition into one with three categories: "the DSM-IV identifies three sub-types of AD/HD, depending on the presence or absence of particular symptoms: Inattentive type, Hyperactive type, and Combined type."
Myth # 2: AD/HD is a Disorder of Childhood
Early discussions of AD/HD theorized that individuals outgrew the disorder (Ingram, Hechtman, & Morgenstein, 1999). This notion has been dispelled by long-term studies showing that anywhere from 70-80 percent of children with AD/HD exhibit significant signs of restlessness and distractibility into adolescence and young adulthood, while a large percentage suffer co-morbid psychiatric disorders, academic failure, and social isolation and/or rejection (Barkley et al., 1990; Barkley, 1998). Research estimates that 1.5 to 2 percent of adults have AD/HD (Hunt, 1997), and between two and six percent of adolescents have AD/HD (Murphy & Barkley, 1996). Cuffe et al. (2001) found that children with persistent AD/HD have more severe AD/HD and adverse risk factors later in life. Adverse factors impact the expression of AD/HD and increase the risk for associated disorders that compromise adjustment over the lifespan. Thus, AD/HD is a lifelong disorder that requires a developmental framework for appropriate diagnosis and treatment (Teeter, 1998).
The DSM-IV recognizes it is not only a development of childhood and does NOT specify age:
n children and teenagers, the symptoms must be more frequent or severe compared to other children the same age. In adults, the symptoms must affect the ability to function in daily life and persist from childhood.
In addition, the behaviors must create significant difficulty in at least two areas of life, such as home, social settings, school, or work. Symptoms must be present for at least six months.
Criteria for the three primary subtypes are:
AD/HD - Inattentive Type
* Fails to give close attention to details or makes careless mistakes.
* Has difficulty sustaining attention.
* Does not appear to listen.
* Struggles to follow through on instructions.
* Has difficulty with organization.
* Avoids or dislikes tasks requiring sustained mental effort.
* Loses things.
* Is easily distracted.
* Is forgetful in daily activities.
AD/HD - Hyperactive Type
* Fidgets with hands or feet or squirms in chair.
* Has difficulty remaining seated.
* Runs about or climbs excessively.
* Difficulty engaging in activities quietly.
* Acts as if driven by a motor.
* Talks excessively.
* Blurts out answers before questions have been completed.
* Difficulty waiting or taking turns.
* Interrupts or intrudes upon others.
AD/HD - Combined Type
* Individual meets both sets of inattention and hyperactive/impulsive criteria.
Also...as for your mark that the APA doesn't recognize adult onset AD/HD - they seem to have not made a comment either way. They do, however, recognize it can LAST a lifetime:
"Current research demonstrates that ADHD is a complex disorder that may affect someone across his or her entire life span." - http://www.apa.org/ppo/issues/pconstest.html
AD/HD is very misunderstood still. Maybe if people (not you, but in general) took the time to research it, these assumptions like the one you quoted wouldn't be made.
