- An important feature of assessing ADHD in an adult is to consider if they are experiencing a co-occurring or co-morbid mental health problem as well as their ADHD.
- The clinician needs to assess if mental health problems the person is experiencing are because of their ADHD or a different condition, as there are often a lot of overlapping symptoms. This is important for the intervention plan.
- Around two thirds of adults with ADHD will also experience a co-occurring mental health condition.
The most common co-occurring conditions are:
- Anxiety
- Mood symptoms (such as depression or extreme mood swings)
- Addiction
- Eating disorders
- Personality disorders
- Self-harm behaviours
- Sleep disorders
