Attention-Deficit/Hyperactivity Disorder (314.xx) Under Neurodevelopment Disorders
DSM-5 Three Subtypes:
1. Predominantly Inattentive type (.00)
2. Predominantly Hyperactive-Impulsive type (.01)
3. Combined type (.01 also)
Plus an “Other” and an “Unspecified”
A. 1. Inattentive type
- 6 or more inattentive sx persisting at least 6 mo to maladaptive degree
A. 2. Hyperactive-Impulsive type
- 6 or more hyperactivity-impulsivity sx persisting at least 6 mo to maladaptive degree
Prevalence of ADHD
One of the most common chronic disorders of childhood
Found across social classes, racial and ethnic groups, and countries but with different prevalence rates
Onset often around 3 to 4 years old (but indications earlier)
Adult ADHD
Disrupts sustained effort, planning, and organization important for effective functioning
Diagnosis in adults relies on establishing sx at the age of 12 and earlier
Attention and Hyperactivity can be confused with or comorbid with a lot of conditions
Anxiety
Depression
Dyslexia
Family dysfunction
Conduct disorder
Tourette’s syndrome
Language impairment
Bipolar disorder
Brain injury
Even intellectual giftedness (boredom)
Comorbidity
More than half of children who qualify for ADHD (67% in one study) have a comorbid diagnosis
Developmental Course
Sx are often present in infancy-high activity, emotional lability, irregular sleep patterns, reduced need for sleep
Preschool years-add short attention span, proneness to tantrums, difficulties with groups
Often remains into adulthood
Summary
- Multiple deficits are needed to explain ADHD
- Even with multiple deficits, the majority of sx variance in ADHD remains unexplained
- There may be an emotional dysregulation subtype of ADHD
- Our theoretical models of the development of ADHD are less adequate than are our theoretical models of some of the other learning disorders…
Diagnosis and Treatment
Diagnosing ADHD relies more on converging evidence arising from observations and developmental/school histories than testing alone
Diagnosis
Take care in diagnosing
- Vulnerable to misdiagnosis
- Lots of rule outs
- In adults, dx rests heavily on childhood symptoms
Assessment of ADHD
Because it is important to distinguish ADHD from other possibilities, the assessment needs to be thorough. It can include:
- Interview, history, school records
- School visit
- Tests WAIS/WISC, WJA/WIAT
- Continuous performance test (CPT)
- MMPI/PIY
Collateral information
However….
Latest research suggests cognitive assessment may not be necessary for ADHD diagnosis, rather behavioral assessment through rating scales (self and vicarious observation) along with thorough consideration of history may be sufficient (Peterson, 2021)
Continuous Performance Tests
But these are only one piece of evidence
- Performance can be impaired for reasons other than ADHD
- And performance can be unimpaired in ADHD
Collateral Information
These are a number of behavioral rating scales that can be useful in assessment
- Multi-dimensional or broad band
- Unidimensional or focal
Useful BUT use intelligently
