1
New cards

attention-deficit/hyperactivity disorder (ADHD)

describes children who display persistent age-inappropriate symptoms of inattention, hyperactivity, and impassivity that are sufficient to cause impairment in major life activities

2
New cards

inattentive

lacking the ability to focus or sustain one's attention. children who are inattentive find it difficult to sustain mental effort during work or play and behave carelessly, as if they are not listening

3
New cards

hyperactive

displaying an unusually high level of energy and an inability to remain still or quiet

4
New cards

impulsive

prone to acting with little or no consideration of possible consequences. this term is frequently used to describe children who suffer from ADHD

5
New cards

what are the primary symptoms/key elements of ADHD?

inattentiveness (IA), and hyperactivity-impulsivity (HI)

6
New cards

Why doesn't increased efforts and stricter rules help children with ADHD?

because most children are already trying hard; they want to do well but are thwarted by their limited control

7
New cards

What are the core symptoms/features of ADHD?

- age-inappropriate inattention, and/or hyperactivity/impulsivity

- problems with sustained attention/focusing

- problems controlling one's behaviour

- absence of care when performing a cognitive act

8
New cards

In order to be diagnosed with ADHD, does the child have to have both hyperactivity and inattention?

No, they both don't need to be present, at least one does.

9
New cards

What is the estimated average cost of ADHD treatment in the US?

$32 billion a year, about $11,000 per child

10
New cards

When and how was ADHD first described?

It was first described in 1902, by George Still who believed that ADHD arose out of poor inhibitory volition and defective moral control

11
New cards

How was ADHD described in 1917-1926?

Because of a flu epidemic, children stared to show behavioral problems (due to brain swelling) of irritability, impaired attention, and hyperactivity, so ADHD became know as brain injured child syndrome (associated with mental retardation)

12
New cards

What was ADHD referred to in the 1940s-1950s?

Minimal brain damage and minimal brain dysfunction (MBD)

13
New cards

in the late 1950s what was ADHD referred to?

Hyperkinesis, which was attributed to the poor filtering of stimuli entering the brain.

14
New cards

What was ADHD referred to after hyperkinesis?

hyperactive child syndrome as motor activity was then considered the main feature of ADHD

15
New cards

how was ADHD defined in the late 1970s?

it was argued that in addition to hyperactivity, deficits in attention and impulse control were also primary symptoms of ADHD; this helped define the DSM criteria

16
New cards

what has recently been emphasized as the central impairments of ADHD?

- poor self-regulation

- difficulty in inhibiting behavior

- motivational deficits

17
New cards

how can ADHD be identified in children? (not talking about symptoms)

only by characteristic patterns of behavior which vary quite a bit from child to child

18
New cards

what the first three symptoms, listed in the DSM-IV, that a child can have under inattention for at least 6 months so that they would qualify as having ADHD?

a) often fails to give close attention to details or makes careless mistakes in schoolwork, work, or other activities

b) often has difficulty sustaining attention in tasks or play activities

c) often does not seem to listen when spoken to directly

19
New cards

What are the fourth, fifth, and sixth symptoms, listed in the DSM-IV, that a child can have under inattention for at least 6 months so that they would qualify as having ADHD?

d) often does not follow through on instructions and fails to finish schoolwork, chores, or duties in the workplace (not due to oppositional behaviour or failure to to understand instructions)

e) often has difficulty organizing tasks and activities

f) often avoids, dislikes, or is reluctant to engage in tasks that require sustained mental efforts (i.e., schoolwork)

20
New cards

What are the seventh, eighth, and ninth symptoms, listed in the DSM-IV, that a child can have under inattention for at least 6 months so that they would qualify as having ADHD?

g) often loses things necessary for tasks or activities (i.e., toys, school assignments, pencils, books,)

h) is often easily distracted by extraneous stimuli

i) is often forgetful in daily activities

21
New cards

What are the first three symptoms, listed in the DSM-IV, that a child can have under hyperactivity-impulsivity for at least 6 months so that they would qualify as having ADHD?

a) often fidgets with hands or feet or squirms in seat

b) often leaves seat in classroom or in other situations in which remaining seated is expected

c) often runs about or climbs excessively in situations in which it is inappropriate (in adolescents or adults, may be limited to feelings of subjective feelings of restlessness)

22
New cards

what are the fourth, fifth, and sixth symptoms, listed in the DSM-IV, that a child can have under hyperactivity-impulsivity (hyperactivity) for at least 6 months so that they would qualify as having ADHD?

d) often has difficulty playing or engaging in leisure activities quietly

e) is often "on the go" or often acts as if "driven by a motor"

f) often talks excessively

23
New cards

what the seventh, eighth, and nineth symptoms, listed in the DSM-IV, that a child can have under hyperactivity-impulsivity (impulsivity) for at least 6 months so that they would qualify as having ADHD?

g) often blurts our answers before questions have been completed

h) often has difficulty awaiting turn

i) often interrupts or intrudes on others (i.e,. butts into conversations or games)

24
New cards

what are some of the limitations of the DSM-IV for ADHD?

1. categorical view (present or not present); research supports dimensionality

2. failure to adjust the number of required symptoms for either age or level of maturity (developmentally insensitive)

3. the required age of 7, as the age of onset, may be too young

4. symptoms must persist for 6 months may be misleading for very young children (too short)

5. symptoms must be demonstrated across at least two environments, may add equivocation (ambiguity) to the diagnosis (conflicting information; blending is better)

25
New cards

what are the common complaints of ADHD (inattention)?

- the child doesn't or won't listen, follow instructions, or finish chores or assignments

26
New cards

according to lecture what types of things fall under inattention (IA)?

- problems with concentration; easily distracted

- not listening

- forgetful and disorganized

- the child fails to complete assignments; difficulty persevering with tasks

27
New cards

what is the primary attentional deficit in ADHD?

sustained attention (i.e, persistence, vigilance)

28
New cards

attentional capacity

the amount of information we can remember an attend to for a short time; children with ADHD are capable of remembering the same amount of information for a short time as other children

29
New cards

selective attention

the ability to concentrate on relevant stimuli and not be distracted by noise in the environment (i.e., when studying for a test (relevant stimuli) how easily are you distracted by voices in a room?)

30
New cards

distractibility

a common term for a deficit in selective attention; children who have ADHD are much more likely to be distracted by stimuli that are highly salient and appealing

31
New cards

sustained attention

vigilance; is the ability to maintain a persistent focus over time or when fatigued

32
New cards

what do children with ADHD work best on?

They work best on self-paced tasks that they have chosen and on tasks that they find especially interesting that do not require them to sustain their attention.

33
New cards

What suggests that children with ADHD may have trouble in alerting and preparation?

The fact that these children may show performance deficits from the very beginning of a task, not just a decrement over time.

34
New cards

alerting

an initial reaction to a stimulus, and involves the ability to prepare for what is about to happen

35
New cards

How may a child with an alerting affect respond to situations?

They respond too quickly in situations requiring a slow and careful approach and too slowly in situations requiring a quick response

36
New cards

Why is it best to view hyperactivity-impusivity as one dimension?

Because when children display one symptom, they usually display the other as well.

37
New cards

what is the main problem in ADHD?

it seems to be one of controlling motor behavior

38
New cards

What sets children with hyperactivity-impulsivity apart from active children?

Unlike other children with a high energy level, children who have hyperactivity-impulsivity tend to accomplish very little (they aren't goal-directed)

39
New cards

According to the lecture, what types of things fall under hyperactivity-impulsivity (HI)?

- Inhibiting inappropriate behaviors and self regulation

40
New cards

According to the lecture, what constitutes hyperactive behavior?

- Excessively energetic behavior that is not goal directed

- Constant fidgeting, difficulty staying seated, constantly moving, excessive talking

41
New cards

According to the lecture, what constitutes impulsive behaviors?

- Difficulty waiting ones turn

- Inability to resist immediate gratification

42
New cards

According to the lecture, which symptoms of the main three found in ADHD emerge first?

hyperactivity-impulsivity emerges before inattention

43
New cards

what have studies show of sleeping ADHD children?

Even when asleep, children with ADHD display more motor activity than other children.

44
New cards

What is the largest difference found in children with ADHD?

When a child with ADHD is in a situation that requires the child to inhibit motor activity, you can see the most difference.

45
New cards

What is hard for children with impusivity?

- They have trouble stopping ongoing behaviour or to regulate their behavior in accordance with the demands of the situation or the wishes of others (i.e., blurting out answers whether right or wrong)

- They have difficulties resisting immediate temptations and delaying gratification

46
New cards

cognitive impusivity

reflected in disorganization, hurried thinking, and the need for supervision

47
New cards

behavioral impusivity

have difficulty inhibiting their response when the situation requires it; includes calling out in class or acting without considering the consequences

48
New cards

what are the two categories of impusivity?

cognitive impulsivity and behavioral impusivity

49
New cards

what are cognitive and behavioral impusivity predictors of?

problems with academic achievement, particularly in reading

50
New cards

what does only behavioral impulsivity predict?

rule-breaking behavior and thus may be a specific sign of increased risk for conduct problems

51
New cards

55
New cards

What is suggested about ADHD-PI compared to HI and C?

56
New cards

What do children with ADHD-PI often have?

they often have a co-morbid disorder - an anxiety and/or mood disorder

57
New cards

subtype

a group of individuals with something in common - symptoms, etiology, problem severity, or likely outcome- something that makes them distinct from other groupings

New cards

what must be done before a diagnosis of ADHD can be done?

a through assessment that includes a developmental history, parent and teacher reports, normed assessment instruments, and behavioral observations

66
New cards

Why is it important to assess both symptoms and impairment functioning for ADHD?

Because a child can display ADHD symptoms without necessarily displaying significant impairment, or a child may display subclinical levels of ADHD symptoms but still suffer significant maladjustment

New cards

who are more accurate raters of ADHD?

teachers more so then parents

90
New cards

why are children with ADHD constantly rejected by peers?

These children do not play by the same rules as others and don't seem to learn from past mistakes, despite their awareness of expected social behaviors and desire to conform to them; blunders appear more thoughtless than intentional
