Is It ADHD, or Is It Sleep, Anxiety, and Your Phone?

Is It ADHD, or Is It Sleep, Anxiety, and Your Phone?

By Mark G. Agresti, MD, Board-Certified Integrative Psychiatrist, Palm Beach, Florida

You cannot focus, you lose your keys, and you have forty browser tabs open. A video told you that is adult ADHD. It might be. It might also be five and a half hours of sleep, a mind full of worry, and a phone you pick up every few minutes.

A large share of the young adults who come to my Palm Beach psychiatry practice arrive with the diagnosis already made. They have watched the videos, taken the online quiz, and recognized themselves. Some of them are right, and treating their ADHD changes their lives. Many are not, and a stimulant would have made the real problem worse. Poor concentration is a symptom, the way a fever is a symptom. The work is finding out what is causing it.

What ADHD Actually Is

Attention-deficit/hyperactivity disorder is a neurodevelopmental condition. That word matters. It means the pattern starts in childhood and follows you through life. It does not appear for the first time at 23 after a job change.

For an adult, the diagnostic criteria ask for all of the following:

• At least five symptoms of inattention, or five of hyperactivity and impulsivity, lasting six months or more.
• Several of those symptoms present before age 12.
• Symptoms that show up in two or more settings, such as work and home.
• Clear interference with work, school, or relationships.
• No other condition that explains the symptoms better.

The last item is where most self-diagnosis goes wrong. Online quizzes ask whether you have the symptoms. They do not ask what else could be producing them.

Look-Alike One: You Are Not Sleeping Enough

Adults need at least seven hours of sleep a night. A great many people in their twenties get five or six and treat it as normal. The part of the brain that suffers first is the prefrontal cortex, which handles sustained attention, working memory, planning, and impulse control. Those are the same functions that are weak in ADHD.

A tired brain is distractible, forgetful, irritable, and impulsive. It loses its place in conversations and reaches for caffeine and sugar. On a symptom checklist, a chronically underslept adult and an adult with ADHD can look almost identical.

The clue is timing. If your focus is noticeably better after a week of real sleep, on vacation or over a quiet holiday, sleep is a large part of your answer. I also look for a body clock that has drifted late, and for snoring or gasping that points to sleep apnea, which is missed in young adults more often than people expect.

Look-Alike Two: Anxiety Is Using Up Your Attention

Working memory is limited. Worry occupies it. When part of your mind is rehearsing what your boss meant by that message, there is less left over for the spreadsheet in front of you. You read the paragraph and nothing goes in.

Anxiety also produces restlessness that passes for hyperactivity, and avoidance that passes for procrastination. Depression does something similar, slowing thinking and flattening motivation until every task feels heavy.

Here is a useful distinction. In ADHD the mind wanders toward whatever is more interesting. In anxiety the mind is pulled toward whatever feels threatening. If your concentration is fine when you are calm and collapses when you are stressed, think about anxiety first.

Look-Alike Three: Your Phone Has Retrained Your Attention

Short videos deliver something new every few seconds. Notifications interrupt whatever you were doing. After enough hours of that, a contract, a textbook chapter, or a long meeting feels unbearable by comparison. That is a habit your attention has learned. It is different from a neurodevelopmental disorder, and it responds to different treatment.

The phone also feeds the first two problems. It pushes bedtime later, and it supplies a steady stream of comparison and bad news.

Other Things That Scatter Your Focus

Daily cannabis blunts memory and motivation. Alcohol wrecks sleep quality. Nicotine and heavy caffeine create a cycle of sharp focus followed by a crash. Thyroid problems, low iron, and low vitamin B12 can all cloud thinking. A proper evaluation asks about every one of these.

Five Questions That Help Sort It Out

• When did it start? Trouble since elementary school points toward ADHD. Trouble that began in the last couple of years points elsewhere.
• What did your teachers say? Old report cards are some of the best evidence there is.
• Does it happen everywhere? ADHD follows you to work, home, and vacation. A problem that lives only at your desk deserves a second look.
• What happens after a week of good sleep? A big improvement tells you a great deal.
• Is your mind bored or worried? Drifting toward what is interesting suggests ADHD. Circling what is frightening suggests anxiety.

Adult ADHD Is Real, and It Is Often Missed

None of this means your symptoms are imaginary or that ADHD is a fad. Plenty of adults had it all along. Bright children compensate, quiet inattentive girls get overlooked, and structured schools and attentive parents can hide the problem until college or a first job removes the scaffolding.

So the errors run in both directions. Some people are handed a stimulant after a ten-minute video visit. Others spend years being called lazy. Both problems have the same fix, which is a careful evaluation.

"Why Not Just Try a Stimulant and See?"

Because it will probably seem to work, and that proves nothing. Stimulant medication sharpens focus for a few hours in most people, with or without ADHD. Feeling more productive on Adderall does not confirm the diagnosis.

Meanwhile, a stimulant can raise anxiety, shorten sleep, and suppress appetite. If sleep and anxiety were the cause, the medication deepens both while hiding the result. You end up needing the pill to function through a problem the pill is helping to maintain.

What a Real ADHD Evaluation Looks Like

Your history, back to childhood. We go through school, work, and relationships, and I ask for report cards or a conversation with a parent when that is possible.

Sleep, screens, and substances. Bedtime, wake time, caffeine, alcohol, cannabis, nicotine, and the screen time number on your phone.

Screening for anxiety, depression, and other conditions. These often travel with ADHD, so the answer is frequently "both."

Rating scales and, when indicated, laboratory work. Standardized measures add structure, and blood work can rule out medical causes.

A plan that fits the findings. If it is ADHD, we treat it properly, with stimulant or non-stimulant medication alongside sleep, exercise, nutrition, and practical skills. If it is something else, we treat that, and we watch what happens to your attention as it improves.

Back to Maya

Maya's history showed no attention problems before the age of 22. Her difficulties began around the time her job changed and her evenings moved onto her phone. We set a fixed bedtime, moved the charger out of her bedroom, cut her afternoon caffeine, and started weekly therapy for the anxiety.

Six weeks later she was sleeping seven and a half hours and her concentration had largely returned. She did not have ADHD, and she did not need a stimulant. The next patient with the same complaint may well have it, and for that person the right medication is the right answer. The point is to know which one you are.

If you are a young adult in Palm Beach, West Palm Beach, Boca Raton, Jupiter, or anywhere in South Florida and you are wondering whether your focus problems are ADHD, an adult ADHD evaluation with a psychiatrist will give you an answer you can trust.
