ADHD or Anxiety? How to Tell the Difference in Adults

Rohan is 28 and works as a software developer in a IT company. In team meetings, his mind goes blank. He misses deadlines, loses his keys and wallet, and lies awake at night with a racing mind. His doctor said, "It's just anxiety. Try to relax." He tried. He did breathing exercises and cut down on coffee. Yet nothing changed in his daily struggle.
What if the problem is not only anxiety? And what if someone else, who has been told they have ADHD, is really struggling with constant worry?

This article explains how ADHD and anxiety are alike, how they are different, what Indian research says, and when to seek help.

At Mitsu across our clinics in Mumbai, our team of mental health professionals who work with adults navigating focus, overwhelm, and emotional wellbeing often meet clients who have been treated for one thing while the real struggle is another, or both.

Both ADHD and anxiety can cause trouble concentrating, restlessness, poor sleep, irritability, and a feeling of being overwhelmed. From the outside, and even from the inside, they can look the same.
But similar-looking symptoms can have different causes. And the cause decides what actually helps.
Many adults also have both at the same time. This article is meant to help you understand, not to diagnose yourself.

Why you cannot focus with ADHD and attention is hard to steer. Your mind wanders even when you care about the task, even when nothing is wrong, and even when you are calm. It is like a TV with a remote that keeps changing channels on its own.

With anxiety, worry takes over the mind. You cannot focus because part of your brain is busy with "What if I fail?" or "What will they think?" Once the fear settles, your focus often returns.
Sneha is 31 and works in marketing in Mumbai. Before every presentation, her heart races and she reads her slides again and again, unable to take them in. But on a relaxed Sunday, she can read a whole book without trouble. That pattern points more towards anxiety.

ADHD and anxiety very often go hand in hand. A 2026 international review which pooled 58 studies, found that adults with ADHD had clearly higher anxiety scores than adults without ADHD.
There is a simple reason. Imagine missing deadlines, forgetting plans, and being told you are careless, year after year. You would start to worry about letting people down. Over time, anxiety grows on top of the ADHD.

Kavita is 38 and lives in Lucknow with her husband and two children. She has been treated for anxiety for years. The medicine and therapy helped her worry, but she still forgets school forms, loses track of time, and cannot finish what she starts. Later, an assessment showed that she had ADHD along with anxiety. Treating only one had left half of the problem untouched.
Having both is common, and it is manageable once both are understood.

In many Indian homes and workplaces, adults hear things like "Tension mat lo", "Overthinking mat karo", "Dhyan nahi deta", or "Tum bahut lazy ho." Focus problems are seen as a lack of effort. Restlessness is seen as nervousness.
Pressure around marks, jobs, marriage, and family expectations can also cause or hide both conditions. So it is easy to say, "It is just stress."
Many people also describe distress through the body, such as headaches, stomach trouble, or constant tiredness, rather than saying they cannot focus or feel worried.
Add to this the limited awareness of adult ADHD, and anxiety becomes the label most likely to be given. Many adults are treated for anxiety for years before anyone asks about ADHD.

Indian studies that compare ADHD and anxiety side by side are still few. But some recent studies show how common ADHD symptoms are among young Indian adults, and how easily they could be mistaken for stress or anxiety. Anxiety often comes along with adult ADHD.

In a recent review published in Frontiers in Psychiatry in 2026, researchers from Yenepoya University in Karnataka went through the Indian research on ADHD. They found that anxiety and depression are among the most common conditions seen alongside adult ADHD, and that this overlap makes diagnosis harder. They also called for care that looks at the whole picture, not just one label.

Many adults with ADHD have another condition too. A 2025 review of Indian studies on adult ADHD, by Mishra and colleagues, found that in clinic settings adult ADHD often comes with other mental health conditions, including anxiety, depression, and substance use. One Indian clinic study it describes found that about 8 in 10 adults with ADHD had at least one such condition. So if anxiety is the only label you have been given, it may be worth asking whether ADHD is also part of the picture.

Poor focus, restlessness, and overwhelm do not always mean ADHD or anxiety. Many other things can cause them, including:
• Depression
• Past trauma or long-term stress
• Poor or broken sleep, including sleep apnoea
• Burnout
• Thyroid problems or other hormonal changes
• Low iron or vitamin B12
• Too much caffeine or too much screen time
• Stress in a relationship or at work

These can also exist alongside ADHD or anxiety. That is why symptoms alone cannot confirm anything, and why a proper assessment matters. A good assessment looks at your whole life, including your childhood, your health, your sleep, and your current stress, so the right problem gets the right support.

The aim is to get the right support for the right problem. Here are some practical ideas.

If ADHD may be part of the picture
• Use visible lists, phone reminders, alarms, and a fixed place for keys, wallet, and phone
• Break big tasks into very small steps
• Use timers, or work next to someone (this is called body doubling)
• Build simple daily routines so you rely less on memory

If anxiety may be part of the picture
• Try slow breathing and grounding when your mind races
• Keep a regular sleep time and limit caffeine
• Notice worry thoughts and question them gently, ideally with a therapist
• Do not avoid what scares you, take small steps towards it

For both
• Get a proper assessment from a qualified mental health professional
• Consider therapy to build coping tools and reduce self-blame
• Move your body, rest well, and set realistic expectations
• Talk to someone you trust about what you are going through
If an assessment confirms ADHD, anxiety, or both, your professional may also discuss other treatment options with you.

You do not need to wait for a crisis. It may be time to reach out if:
• Your symptoms have lasted for months and affect your work, studies, or relationships
• Treatment for anxiety has helped only partly
• You have struggled with focus and organisation since childhood
• Worry, exhaustion, or low mood keep coming back
• You feel you are working much harder than others, with less to show for it

At Mitsu across our clinics in Mumbai, our approach is collaborative and tailored to each person. We start by understanding your story and, where needed, support you with a proper assessment to sort out ADHD, anxiety, or both. Then we work together through individual therapy and/or psychiatry support that caters to your concerns.
