ADHD & ADD in Adults - Symptoms, Diagnosis and Treatment in Practice
ADHD in Adults – More Than a Childhood Disorder
Attention Deficit/Hyperactivity Disorder (ADHD) is frequently misunderstood as a condition exclusive to children. However, current research clearly demonstrates that ADHD is a lifelong, neurobiological disorder that often persists into adulthood. Many adults only begin to recognize the signs later in life, typically when challenges in daily functioning prompt further investigation.
ADHD in adults is often underdiagnosed—particularly among women—due to differing symptom presentation. Instead of outward hyperactivity, symptoms may manifest as internal restlessness, chronic exhaustion, or persistent overwhelm. These subtler signs are no less impactful on quality of life.
Recognizing ADHD in Adulthood
Adult ADHD symptoms are generally less overt than those seen in childhood. Hyperactivity may appear as an internal sense of unease or tension. Common symptoms include:
• Difficulty concentrating, distractibility, “mental fog”
• Forgetfulness and disorganization in daily routines
• Impulsive behavior, such as spontaneous purchases or emotional outbursts
• Mood instability, irritability, or frustration
• Procrastination and difficulty completing tasks
Without appropriate diagnosis and support, individuals may be at increased risk for comorbid conditions, including depression, anxiety disorders, obsessive-compulsive symptoms, and substance use disorders.
“Importantly, many mistakenly attribute their difficulties to personal shortcomings, rather than a legitimate and treatable condition.”
What Is ADD?
ADD (Attention Deficit Disorder) is a subtype of ADHD without prominent hyperactivity. Individuals with ADD may appear calm, introspective, or withdrawn. Key features include:
• Persistent inattentiveness and daydreaming
• Pronounced distractibility
• Low drive or motivation
• Internal restlessness without visible fidgeting
“ADD often goes unnoticed, particularly in women and girls, leading to chronic self-doubt and delayed access to care. However, it is a well-defined and manageable neurodevelopmental disorder.”
Diagnosis: Comprehensive, Evidence-Based, and Individualized
Diagnosing ADHD in adults requires clinical expertise, a structured approach, and sensitivity to the individual’s history and current challenges. In our practice, we rely on a combination of clinical interviews and validated diagnostic instruments:
DIVA-5 Interview
The Diagnostic Interview for ADHD in Adults is based on the DSM-5 criteria and assesses symptoms across the lifespan. It provides a structured evaluation of ADHD characteristics in various domains and includes input from close contacts where relevant.
Klenico® Digital Test System
This advanced tool supports differential diagnosis by helping to rule out other psychiatric conditions (e.g. depression, autism spectrum disorders, obsessive-compulsive traits) that may mimic or overlap with ADHD.
“A reliable diagnosis often brings a profound sense of relief and clarity:
Now everything finally makes sense.”
Medication: Guideline-Based and Carefully Monitored
For moderate to severe ADHD, pharmacological treatment is considered first-line therapy. In our clinic, we offer individualized medication management using the following:
• Methylphenidate (e.g. Ritalin®, Medikinet®, Concerta®): A stimulant that modulates dopamine and norepinephrine levels, improving attention and reducing impulsivity.
• Lisdexamfetamine (Elvanse®): A long-acting prodrug offering stable effects throughout the day; often preferred in cases of inattention and low hyperactivity.
• Atomoxetine (Strattera®): A non-stimulant option, suitable for select indications or when stimulants are not well-tolerated.
We provide comprehensive medical oversight, including initial workups (blood pressure, lab tests, ECG) and close monitoring for potential side effects such as insomnia, appetite changes, or cardiovascular concerns.
Comprehensive, Multimodal Treatment Approach
Medication forms the basis of treatment for many patients, but sustainable improvement typically requires an integrative therapeutic plan. Our practice offers a range of supportive services:
• Cognitive Behavioral Therapy (CBT) – Developing awareness of thought patterns and practical coping strategies
• ADHD Coaching – Enhancing executive functioning, time management, and goal-setting
• Mindfulness Training – Managing emotional dysregulation and improving focus
• Group Interventions – Including skills training and peer support networks
What Not to Rely On
Alternative treatments such as Bach flower remedies or homeopathy, while popular, lack scientific evidence for effectiveness in ADHD. Research consistently shows no benefit beyond placebo. We therefore advise against their use in clinical ADHD management.
Conclusion: ADHD Is Real, Recognizable, and Treatable
ADHD in adulthood is not a passing trend—it is a clinically recognized, often overlooked condition that can have significant impact if left untreated. The good news: with an accurate diagnosis and tailored treatment plan, ADHD is highly manageable.
