In addition to taking a binary approach to ADD–you either have it or you don’t–most ADD diagnostic tools do not take into account the fact that several conditions can mimic ADD symptoms. Psychiatric disorders that mimic ADD symptoms include anxiety, mood and adjustment disorders, learning and language deficits, and some psychotic disorders. Other conditions that can mimic ADD symptoms include:
- seizure disorders
- vision or hearing problems
- lead poisoning
- liver disease
- sleep apnea
- thyroid conditions
- drug interactions
- low blood sugar (hypoglycemia)
- brain injuries
- excessive stress
Substances like steroids, antihistamines, anti-convulsants, caffeine and nicotine can also have negative effects that mimic ADD symptoms.
It is important to inform your mental healthcare provider if you have a history of these conditions. He or she may consider a different diagnosis, or refer you to a specialist to assist with your ADD diagnosis.
