📋 Adult ADHD Symptoms

15 often overlooked signs to better understand this disorder

🧠 ADHD in Adults: An Underdiagnosed Disorder

Long considered a childhood disorder, ADHD (Attention Deficit Hyperactivity Disorder) persists into adulthood in 60 to 70% of cases. Yet, many adults live with undiagnosed ADHD, attributing their difficulties to a lack of willpower or personality traits.

In adults, symptoms evolve. Physical hyperactivity often decreases, giving way to an inner restlessness. Attention difficulties and impulsivity, however, persist and can have a significant impact on professional, personal, and relational life.

🔬 Key Figures

Approximately 2.5% of adults worldwide are affected by ADHD. In France, it is estimated that 3 out of 4 adults with ADHD are undiagnosed, which amounts to nearly 1.5 million people.

Inattention Symptoms

The difficulty in maintaining attention is the central symptom of ADHD

1

Difficulty concentrating on lengthy tasks

You struggle to stay focused on a task that requires sustained mental effort. Reading a long document, following a meeting, completing a project: all of this becomes a real challenge. Your mind "wanders" frequently.

"I have to reread the same paragraph 5 times; my mind drifts elsewhere without me realizing it."
2

Chronic procrastination

You consistently delay tasks, especially those that seem boring or complex. This is not laziness: it is a difficulty to "start" that is typical of ADHD. Paradoxically, you can be very productive at the last minute, under the pressure of a deadline.

"I have a month to do this report, but I do it the night before at 3 AM."
3

Disorganization and frequent forgetfulness

Your desk is messy, you forget appointments, you regularly lose your keys, phone, wallet. Despite all your efforts, you struggle to maintain an organization system.

"I bought 10 different planners; none worked for more than 2 weeks."
4

Difficulty managing time

You consistently underestimate the time needed to complete a task. You are often late, not out of disrespect but because you lose track of time. This is called "time blindness."

"I get ready to leave in 5 minutes, and 45 minutes later I'm still here."
5

Hyperfocus on certain subjects

Paradoxically, you can intensely focus on subjects that fascinate you, to the point of forgetting everything else (eating, sleeping, your obligations). This is hyperfocus, a state of extreme concentration characteristic of ADHD.

"When I'm passionate about something, I can spend 8 hours straight without noticing the time."

Impulsivity Symptoms

Difficulty inhibiting automatic reactions

6

Speaking without thinking

You often interrupt others or finish their sentences. You say things you immediately regret afterward. Your words come out faster than your filter can stop them.

"I often regret what I say, but it comes out before I can stop myself."
7

Impulsive decisions

You make quick decisions without considering all the consequences: impulsive purchases, sudden career changes, commitments made on a whim that you later regret.

"I bought a car because I thought it was pretty, without checking if I could afford it."
8

Impatience

Waiting is particularly difficult for you, whether in a queue, on the phone, or for results. You feel internal tension when things do not move quickly enough.

"Waiting 2 minutes at a red light feels like an eternity."
9

Seeking thrills

You need constant stimulation. Boredom is unbearable for you. You may take risks or seek exciting situations to feel "alive."

"I often change jobs or projects because I get bored quickly."
🌀

Hyperactivity Symptoms

Physical restlessness of childhood often becomes internal in adults

10

Inner restlessness

Even if you do not move physically, you feel internal tension, like a motor running continuously. Your mind is always active, which can be exhausting.

"Even when I'm sitting, I feel like my brain is running a marathon."
11

Need to move

Staying seated for long periods is difficult for you. You tap your foot, play with a pen, get up frequently. During long meetings, you feel physical discomfort.

"In meetings, I have to pretend to take notes to channel my need to move."
12

Overwhelm and difficulty relaxing

You struggle to "unplug." Rest can feel uncomfortable. You often overload yourself with projects and activities because inactivity makes you anxious.

"Relaxing vacations stress me out more than they relax me."
💭

Emotional Symptoms

Emotional dysregulation, often overlooked, is a major aspect of adult ADHD

13

Intense and changing emotions

Your emotions are often vivid and change quickly. A small annoyance can trigger a strong reaction. You can go from enthusiasm to frustration in a matter of minutes.

"My loved ones tell me that my reactions are sometimes 'disproportionate.'
14

Sensitivity to rejection

You are particularly sensitive to criticism or perceived rejection. An innocuous remark can deeply affect you. This is known as "Rejection Sensitive Dysphoria" (RSD).

"When my boss makes a comment, I think about it for days."
15

Low self-esteem

After years of unexplained difficulties, negative remarks, and failures, many adults with ADHD develop low self-esteem. They feel "different," "deficient," or "not good enough."

"I've always felt smart but never reached my potential."

👫 ADHD: Differences Between Men and Women

ADHD often manifests differently by gender, which partly explains the underdiagnosis in women.

Aspect Men Women
Dominant Presentation Hyperactivity-Impulsivity Inattention
Hyperactivity More visible, physical More internalized, mental
Expression Externalized behaviors More discreet symptoms
Compensation Less social masking Significant efforts to "appear normal"
Diagnosis Earlier (childhood) Later (often in adulthood)
Frequent Comorbidities Behavioral disorders Anxiety, depression, eating disorders

💡 Note: Women are diagnosed on average 5 to 10 years later than men. Many discover their ADHD in adulthood, often following the diagnosis of their child.

🩺 Towards Diagnosis: What to Do If You Recognize Yourself?

If you recognize yourself in several of these symptoms, here are the recommended steps:

1. Self-Assessment

Start by taking our free attention test. While not diagnostic, it will give you an initial indication of your attentional functioning and concrete elements to share with a professional.

2. Medical Consultation

Make an appointment with your primary care physician. Describe your difficulties and request a referral to a specialist. You can also consult a psychiatrist or neurologist directly.

3. Diagnostic Assessment

The diagnosis of ADHD in adults is based on a thorough clinical interview exploring your history since childhood, standardized questionnaires (ASRS, DIVA, CAARS), and sometimes neuropsychological tests. The professional will also rule out other possible causes of your symptoms.

4. Management

If the diagnosis is confirmed, several options exist: psychoeducation (understanding ADHD), CBT (cognitive behavioral therapy), coaching, and if necessary, medication. Management is personalized according to your needs.

⚠️ Important

Do not self-diagnose. Only a qualified healthcare professional can diagnose ADHD after a complete evaluation. Many conditions can present similar symptoms (anxiety, depression, sleep disorders, thyroid disorders...).
