Other Conditions & ADHD

When it could be ADHD, or something else

Many ADHD symptoms overlap with symptoms of other conditions

, such as anxiety, bipolar disorder, depression, and substance abuse disorder, to name a few. For example:

RESTLESSNESS
IS COMMON IN BOTH
ANXIETY

RAPID SPEECH
IS COMMON IN BOTH
BIPOLAR DISORDER

POOR CONCENTRATION
IS COMMON IN BOTH
DEPRESSION

IMPULSIVE BEHAVIOUR
IS COMMON IN BOTH SUBSTANCE USE DISORDER

This is not a complete list. Please speak to your doctor or mental health professional about the complete diagnostic criteria for each condition.

When these types of overlapping symptoms are present, a doctor must carefully determine which disorder the patient has. This is called a differential diagnosis.

If both conditions are present at the same time (e.g., ADHD and depression together), they are called comorbid disorders.

The presence of these other disorders and symptoms that overlap with ADHD can sometimes be part of the reason that a person with ADHD might not be diagnosed yet.

BASED ON THE LITERATURE, MOST PEOPLE WITH ADHD ALSO HAVE AT LEAST ONE COMORBID DISORDER

  • 85% of adults with ADHD have a comorbid disorder
  • In children with ADHD:
    • 50–90% have at least one comorbid disorder
    • Approximately half have at least two comorbid disorders

Situations or events that create change in our lives can be extremely stressful and overwhelming. These periods of increased stress can make mental health conditions worse, including ADHD and the comorbid conditions often associated with it.

It is essential during these times to take care of yourself and seek additional support by staying connected to family and friends, as well as talking to your doctor.
