📋 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.
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.

The difficulty in maintaining attention is the central symptom of ADHD
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.
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.
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.
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."
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.
Impulsivity Symptoms
Difficulty inhibiting automatic reactions
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.
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.
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.
Seeking thrills
You need constant stimulation. Boredom is unbearable for you. You may take risks or seek exciting situations to feel "alive."
Hyperactivity Symptoms
Physical restlessness of childhood often becomes internal in adults
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.
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.
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.
Emotional Symptoms
Emotional dysregulation, often overlooked, is a major aspect of adult ADHD
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.
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).
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."
👫 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.
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...).
