ADHD in Adults
Prevalence:
4% of adults
About 50% of kids with ADHD continue to have symptoms into adulthood
The more severe symptoms are in childhood, the greater the chance of continuation
Cause:
Not well understood
Decreased activity of dopamine and noradrenaline in the part of the brain responsible for executive function
Genetics:
Strong genetic component
The risk of ADHD in parents and siblings of kids with ADHD is increased 2 to 8 times e.g. 20 to 80% chance
Characteristics:
Inattention
Impulsivity
Restlessness
Functional impairment
Symptoms:
Problems arise in the following areas:
Executive Dysfunction
Self-directed actions to choose goals and to create, enact, and sustain efforts toward those goals.
Working memory
Task shifting
Initiation
Self-inhibition
Self-monitoring
Inattention
Remaining focused on a task, especially for long periods
Organizing and prioritising activities
Following through and completing tasks
Forgetfulness
Time management
Impulsivity
Excessive involvement in activities or speech that has a high potential for consequences
This can lead to end relationships or quitting jobs
Restlessness (Hyperactivity)
Feeling fidgety or restless
Talking too much and/or interrupting others
Emotional Dysregulation
Mood lability
Irritability
Anger outbursts
Low frustration tolerance
Unable to engage in appropriate behaviour when distressed (e.g. at work)
Other impairments:
ADHD leads to higher rates in:
Occupational difficulties
Criminal activity
Substance abuse problems
Traffic accidents and tickets
Anxiety and mood disorders
Overall mortality, mostly from traffic accidents
Assessment:
The goal of the assessment is to identify symptoms and behaviour consistent with the diagnostic criteria for ADHD and to rule out other disorders such as mood and/or anxiety disorders.
The assessment should focus of adult manifestations of ADHD including:
Hyperactivity symptoms
Restlessness
Constant talking
Constant activity
A tendency to choose very active jobs
Impulsivity symptoms – Impulsivity may have more serious consequences in adults than during childhood
Ending relationships
Quitting jobs
Overreacting to frustrations
More driving violations and accidents
Inattention symptoms
Procrastination
Difficulty making decisions
Poor time management
Difficulty in organizing activities
Management:
First-line treatment is a combination of medication and CBT targeting executive dysfunction.
For most adults, a simulation medication is preferred
If ADHD and depression only, consider SSRI / SNRI only initially
If ADHD and anxiety disorder, use a stimulant and SSRI / SNRI
If ADHD only, then a stimulant only
