Is it ADHD or depression?
Short answer
It can be either, both, or something else, and only an evaluation can tell. NIMH lists difficulty concentrating, remembering, and making decisions among common symptoms of depression, and names depression among conditions that can cause ADHD-like symptoms. The two can also occur together. If you are in crisis, call or text 988 in the US, or contact your local emergency number.
When everything feels harder than it should, it is natural to wonder whether attention is the problem or whether low mood is draining everything, attention included. The sources below explain why that question is hard to answer from the inside, and why it is worth asking a clinician rather than settling it alone.
If you are struggling right now
If you are having thoughts of suicide or self-harm, or you feel unsafe, call or text 988 in the US, or contact your local emergency number. Questions about attention can wait until you are safe and supported.
Both can affect concentration and memory
So the same visible result, such as a stack of unopened mail or a project that never gets finished, can have more than one story behind it. That is not something a reader can reliably untangle from a list of symptoms, and this page does not try.
The two can occur together
How a clinician approaches it
An evaluation can look at mood and attention at the same time, follow up on details, and consider physical causes. That is a job for a trained person with time to ask questions.
Questions to take with you
- Could what I am describing involve low mood, attention, both, or something else?
- Is there anything physical, such as thyroid function or a medication I take, worth checking?
- How do you look at mood and attention together?
- What would be useful to know about my school years and earlier life?
- What should I notice or write down before we talk again?
Notes that help
- Over the last few months, how have my mood, energy, sleep, and appetite been?
- What are a few concrete examples of things I meant to do and did not, and what got in the way?
- Who in my life could describe how I have seemed lately?
Plain, specific notes are more useful than a theory about yourself. Write what happened and when, and let the clinician do the sorting.
A starting point for your next step.
You can take the free screener at any time and bring the answers to an appointment. If your mood is very low, talking with someone comes first.Frequently asked questions
Can ADHD and depression happen together?
Yes. NIMH says ADHD often co-occurs with depression, and the NHS says people with ADHD may be more likely to have depression. A clinician can look at both at the same time.
Can depression make me forgetful?
NIMH lists difficulty concentrating, remembering, or making decisions among common symptoms of depression. Forgetfulness can have many causes, so it is worth raising with a health care provider.
Who should I talk to first?
NIMH names a primary care doctor, psychologist, or psychiatrist as good places to start. Mention both your mood and your attention. If you are in crisis, call or text 988 in the US, or contact your local emergency number.
