Get urgent help if you cannot stay safe

If you or someone else is in immediate danger, has seriously harmed themselves, or cannot stay safe, call 999 or go to A&E now.

For urgent mental health help in England when it is not an emergency, call NHS 111 and select the mental health option, or use NHS 111 online.

You can also call Samaritans free at any time on 116 123.

The dedicated guide to ADHD and suicidal thoughts puts all urgent actions at the top. This article cannot assess your safety and is not a crisis service.

The short answer

ADHD and depression can occur together. A 2022 systematic review of adult ADHD comorbidities found that mood disorders were more prevalent in adults with ADHD than in comparison groups. The estimates varied across studies because diagnostic tools and study populations differed.

That evidence supports looking for both conditions. It does not support telling every adult with ADHD that depression is inevitable, quoting one dramatic percentage as a personal risk, or assuming that low motivation is always caused by dopamine.

When to ask for an assessment

Speak to a GP if low mood has lasted for 2 weeks or more, is affecting daily life, or is difficult to cope with. Seek help sooner if symptoms are severe, worsening, or include thoughts of self-harm or suicide.

How the symptoms can overlap

ADHD and depression can both affect concentration, memory, sleep, energy, motivation and day-to-day tasks. The underlying pattern may be different, but a single symptom cannot reliably separate them.

AreaPossible ADHD patternPossible depression pattern
HistorySymptoms and impairment trace back to childhoodA noticeable change from the person's usual mood or functioning
AttentionDistractibility, losing track, difficulty sustaining effortReduced concentration or slowed thinking alongside other mood symptoms
MotivationStarting and sustaining tasks varies with structure, urgency and interestReduced drive may be broad and accompanied by hopelessness or loss of pleasure
MoodFrustration or emotions may change quickly with eventsLow mood may be persistent for weeks or months
EnjoymentEnjoyment may still be present even when organisation is difficultActivities that were previously enjoyable may no longer feel rewarding
SleepDelayed bedtime, inconsistent routine or a restless mindSleeping more or less than usual, often with other depressive symptoms
Self-viewShame may relate to repeated difficulties and criticismWorthlessness, hopelessness or excessive guilt may be central symptoms

These are tendencies, not diagnostic rules. A person with both conditions may show a mixture. Someone with depression can still concentrate on an absorbing activity, and someone with ADHD can experience persistent loss of interest. Hyperfocus does not rule depression out.

What a clinician will consider

A proper assessment looks beyond a checklist. A GP or mental health professional may ask about:

  • when the change in mood, energy, sleep or interest began
  • whether symptoms are present most days and how they affect functioning
  • childhood and adult history of attention, impulsivity and hyperactivity
  • work, study, relationships and daily living
  • anxiety, trauma, substance use and physical health
  • current medicines and recent medication changes
  • previous periods of depression and what helped
  • any periods of unusually elevated or irritable mood
  • thoughts of self-harm or suicide

The last two areas matter because bipolar disorder, medication effects and other conditions can alter the treatment plan. Do not stop prescribed medicine before speaking to the responsible clinician unless emergency services tell you otherwise.

Why the conditions may be associated

Research supports an association, but no single explanation accounts for every person.

Shared and separate vulnerabilities

Genetic, developmental and environmental factors may contribute to both ADHD and depression. A longitudinal study of childhood ADHD and recurrent depression in young adulthood found an association and explored possible pathways, but it did not show a simple one-cause explanation.

The effect of long-term impairment

Repeated difficulty at school, work, home or in relationships can affect confidence and mood. Late recognition may leave someone interpreting ADHD-related impairment as a character failure. The guide to late-diagnosed ADHD explores that experience.

This does not mean depression is merely "secondary ADHD" or will disappear once the ADHD is treated. Depression is a condition in its own right and deserves assessment.

Sleep, stress and other conditions

Persistent sleep disruption, chronic stress, pain, substance use, anxiety and other health conditions can affect both mood and attention. The ADHD and sleep guide can help you prepare questions, but a clinician should assess substantial changes in sleep or energy.

Treatment when ADHD and depression coexist

Treatment should be personalised. The NHS explains that depression care may include guided self-help, talking therapies, behavioural activation, exercise programmes, antidepressants or a combination, depending on severity and need.

NICE depression guidance emphasises shared decision-making. The clinician should discuss benefits, risks, preferences, previous treatment, other conditions and the practical ability to engage with an option.

Talking therapies

Therapies used for depression include cognitive behavioural therapy, behavioural activation, interpersonal therapy and counselling in appropriate circumstances. A therapist may adapt delivery when ADHD affects memory, time management or between-session tasks.

Adaptations might include shorter written summaries, reminders, visible examples, one practice task at a time and checking whether instructions were understood. Ask the therapist what adjustments are possible instead of assuming standard treatment will not work.

In England, adults can self-refer to NHS talking therapies for anxiety and depression without first seeing a GP. A GP remains important for diagnostic uncertainty, medication, physical-health checks, significant impairment or worsening symptoms.

Medication

There is no evidence-based rule that an SSRI will fail simply because someone has ADHD. There is also no safe rule that treating ADHD will remove depression.

Medication choices should be made by qualified prescribers who know about every medicine, supplement and substance being used. NICE recommends slower ADHD medication titration and more frequent monitoring when depression or another mental health condition is present.

Contact the prescriber promptly if hopelessness or suicidal thoughts begin or worsen after starting or changing an antidepressant. Do not change an antidepressant or ADHD medicine on the basis of an online article. The ADHD medication guide explains the usual UK prescribing pathway.

Which condition is treated first?

The answer depends on the individual. Safety and severe symptoms take priority. In other cases, clinicians may address both conditions in a coordinated way or begin with the condition causing the greatest impairment.

Ask for a written plan covering:

  • what each treatment is intended to improve
  • who is responsible for prescribing and monitoring
  • what side effects or changes to report
  • when progress will be reviewed
  • what to do if symptoms worsen

ADHD-friendly steps while arranging care

These ideas are not treatments for depression. They may reduce the executive-function load involved in getting help.

  1. Use one sentence to start. Tell the GP receptionist: "My mood has been low for more than 2 weeks and it is affecting daily life."
  2. Write examples before the appointment. Include changes in sleep, appetite, interest, concentration, work and relationships.
  3. Bring a medication list. Add supplements, alcohol and other substances so interactions can be assessed.
  4. Ask for the plan in writing. Note the next appointment, who to contact and what to do if symptoms worsen.
  5. Use external reminders. Put appointments in a calendar immediately and ask a trusted person to help if you want that support.
  6. Lower task demands temporarily. Choose a small essential action rather than trying to repair every routine at once.

  • Childhood and adult ADHD history
  • All medicines, supplements, alcohol and other substances
  • What has helped or made symptoms worse before
  • The follow-up and crisis plan

Where mentoring fits

ADHD mentoring is not therapy, depression treatment or crisis care. It cannot diagnose either condition, decide which one is causing a symptom, or advise on medication.

When someone is stable and has appropriate clinical support, mentoring may help with practical ADHD-related needs such as appointment preparation, reminders, prioritising tasks, simplifying routines and putting clinician-agreed strategies into daily life.

Key points

  • ADHD and depression can coexist, but one does not automatically cause the other.
  • Concentration and motivation overlap, so timing, history and the full symptom pattern matter.
  • Persistent low mood or loss of interest deserves clinical assessment.
  • Treatment is based on severity, safety, preferences and other conditions.
  • ADHD medication and antidepressant decisions belong with qualified prescribers.
  • Practical support can complement clinical care but cannot replace it.

Frequently Asked Questions

Can adults have ADHD and depression at the same time?
Yes. Depression is reported more often in groups of adults with ADHD than in adults without ADHD, and the two conditions can coexist. Prevalence estimates vary across studies because populations and diagnostic methods differ.
How can I tell ADHD from depression?
ADHD is a neurodevelopmental condition with symptoms that begin in childhood, while depression usually involves a change in mood, interest, energy or functioning over a period of time. Concentration, sleep, motivation and task completion can be affected by either condition, so a clinician uses history, timing, context and the full symptom pattern.
Can depression look like ADHD?
Depression can cause poor concentration, forgetfulness, low motivation and difficulty completing tasks. Those symptoms can resemble ADHD, but ADHD diagnosis requires evidence of symptoms beginning in childhood and causing impairment in more than one area of life.
Should ADHD or depression be treated first?
There is no single sequence for everyone. The clinical team should consider severity, safety, current impairment, other conditions, medication interactions and the person's preferences. Urgent or severe depression may require immediate attention, while both conditions may need a coordinated plan.
Where can I get help for depression in the UK?
Speak to a GP if you think you may be depressed. In England, adults can also self-refer to NHS talking therapies for anxiety and depression. If you or someone else is in immediate danger or cannot stay safe, call 999 or go to A&E.
