Clarify whether symptoms fit ADHD, depression, or both using an evidence‑informed side‑by‑side comparison used in clinical practice.

ADHD and depression share some visible patterns but have different drivers. This comparison chart looks at eight dimensions - focus, motivation, sleep, mood - so you can see where the overlap is and where they diverge.
A marketing director at a tech startup has been struggling with missed deadlines and scattered focus for six months. She attributes it to burnout from rapid company growth and increased responsibilities. Her manager suggested coaching to help with stress management and prioritization.
Frame this as a pattern-mapping exercise, not a diagnostic tool. 'Before we build stress management strategies, let's map what you're actually experiencing. Sometimes what looks like burnout has different roots.' Expect resistance to the ADHD column - many high-performing professionals dismiss it as childhood hyperactivity. Normalize: 'ADHD in adults often looks like chronic overwhelm, not bouncing off walls.'
Notice which column she reads first and how long she spends on each. If she rushes through ADHD and lingers on depression, she may be avoiding recognition. Watch for 'aha' moments in the initiation and consistency rows - these often reveal longstanding patterns she's attributed to character flaws. Quick dismissal of either column without reading suggests defensive processing.
Start with the rows where she identified with both sides. 'Read me the rows where you saw yourself in both columns.' Then focus on timeline: 'When you think back to college or your first job, were these patterns already there?' The question that opens this up: 'What would change about your approach to work if this overwhelm isn't about your current role?'
If she identifies strongly with depression symptoms but has never been screened, that's moderate severity. Response: continue coaching while encouraging clinical evaluation. If she dismisses obvious ADHD patterns while describing classic executive function struggles, the denial itself may need addressing before strategies will stick.
An operations manager at a manufacturing company has been treated for depression for two years. Medication stabilized his mood, but he still struggles with project management, time estimation, and follow-through. His therapist suggested coaching for workplace skills, but he's questioning whether something else is at play.
Position this as a comorbidity check, not a replacement diagnosis. 'Depression treatment helped your mood - that's clear. Now let's see if there's a second pattern affecting your executive function. Many people have both.' He may resist because it feels like starting over with his mental health journey. Acknowledge: 'This isn't about the depression treatment failing. It's about whether there's more than one thing to address.'
He'll likely identify with depression symptoms easily since he's been in treatment. Watch his reaction to ADHD executive function descriptions - surprise, recognition, or dismissal. If he says 'but I'm not hyperactive,' he's working from outdated models. Notice whether he attributes ADHD symptoms to depression or sees them as separate patterns.
Start with the timeline question: 'Think back to before your depression diagnosis. Were the work struggles already there?' Then move to treatment response: 'Your mood improved with medication, but these work patterns didn't. What does that tell you?' The key question: 'If these are two separate issues, how would that change what you work on in coaching versus therapy?'
If he's been in depression treatment but work performance hasn't improved despite mood stabilization, that suggests possible comorbidity. Severity: low to moderate. Response: continue coaching while suggesting he discuss ADHD screening with his current provider. Don't duplicate or contradict ongoing mental health treatment.
A senior consultant at a professional services firm excels in client-facing work and complex problem-solving but consistently falls behind on timesheets, expense reports, and internal meetings. She's concerned about promotion prospects and wonders if she's becoming depressed about her career trajectory.
Frame this as a task-type analysis, not a performance issue. 'You're clearly capable - your client work proves that. Let's look at whether different types of tasks are hitting different cognitive systems.' She may resist the ADHD column because her client success doesn't match her mental model of ADHD. Explain: 'ADHD often shows up as inconsistent performance, not across-the-board struggles.'
Watch for recognition in the ADHD initiation row - difficulty deciding what to do first often explains why administrative tasks pile up while client work flows smoothly. Notice if she attributes the pattern to laziness or lack of discipline rather than cognitive differences. Strong identification with both columns in the mood section may indicate secondary depression from chronic work struggles.
Start with the performance split: 'You described excelling with clients but struggling with internal tasks. Which column better explains that pattern?' Then explore context dependency: 'What's different about client work that makes it easier to engage with?' The question that creates movement: 'If this is about how your brain processes different types of tasks, what would you set up differently?'
If she's developed mood symptoms specifically around work performance while other life areas remain stable, that suggests secondary depression from unaddressed executive function challenges. Severity: moderate. Response: coaching can address task management strategies, but if mood symptoms are significant, encourage parallel mental health support.
A finance executive in his fifties recently learned his teenage daughter has ADHD. During her evaluation process, he recognized similar patterns in himself - difficulty with routine tasks, hyperfocus on interesting projects, chronic lateness despite good intentions. He's questioning whether his career-long 'personality quirks' might be something else.
Normalize late-in-life recognition: 'ADHD often runs in families, and parent diagnosis after a child's evaluation is common. You've built successful workarounds, but understanding the underlying pattern can make them more intentional.' He may minimize his experience because he's been successful. Counter: 'Success doesn't rule out ADHD - it often means you've developed effective coping strategies without realizing it.'
He'll likely focus on the consistency and onset rows since these validate lifelong patterns he's noticed. Watch for relief when reading ADHD descriptions - many late-diagnosed adults feel validated rather than concerned. Notice if he starts reframing past struggles as neurological rather than character-based. Resistance usually shows up as 'but I've managed fine' rather than denial of symptoms.
Start with pattern recognition: 'As you read through this, what clicked as familiar from your own experience?' Then explore the reframe: 'If these patterns have been there all along, what does that change about how you understand your career path?' The opening question: 'Your daughter's diagnosis made you wonder about yourself. What would it mean if you're both wired similarly?'
Late-life ADHD recognition rarely creates crisis, but it can trigger grief about missed opportunities or self-criticism about past struggles. Severity: low. Response: continue coaching with focus on leveraging existing strengths and optimizing current systems. If he expresses significant regret about the past, consider referral for processing that separately.
