Whether you're considering getting assessed or you've recently been diagnosed and want to learn more, this article will give you the knowledge and resources you need to take control of your ADHD journey.

What Is Adult ADHD? Understanding the Condition

Adult ADHD is a neurodevelopmental disorder that persists from childhood into adulthood for approximately 60-70% of individuals diagnosed as children. However, many adults receive their first diagnosis in adulthood—sometimes not until their 30s, 40s, 50s, or beyond.

How ADHD Presents in Adults

While childhood ADHD often manifests as obvious hyperactivity and impulsivity, adult ADHD typically looks different. The hyperactivity tends to internalize, and adults struggle more with:

• Inattention: Difficulty focusing on tasks, easily distracted, forgetful

• Executive dysfunction: Problems with planning, organizing, time management, prioritizing

• Impulsivity: Interrupting others, making hasty decisions, difficulty waiting

• Emotional dysregulation: Mood swings, irritability, low frustration tolerance

• Restlessness: Inner sense of constant motion, difficulty relaxing

Adult ADHD Symptoms Checklist

Common symptoms that persist into adulthood include:

Inattentive symptoms:

• Difficulty sustaining attention during work or conversations

• Frequently losing things (keys, phone, wallet)

• Forgetfulness in daily activities (appointments, deadlines)

• Making careless mistakes at work

• Trouble following through on instructions

• Avoiding tasks requiring sustained mental effort

Hyperactive-impulsive symptoms:

• Feeling internally restless or "on the go"

• Difficulty waiting your turn

• Interrupting or intruding on others

• Talking excessively

• Fidgeting or inability to sit still comfortably

• Starting multiple projects but finishing few

Executive function challenges:

• Poor time management and chronic lateness

• Difficulty organizing tasks and activities

• Procrastination followed by frantic last-minute work

• Trouble breaking large tasks into manageable steps

• Difficulty prioritizing what's important

Getting Diagnosed with Adult ADHD in the UK

Step 1: Recognizing Symptoms and Self-Screening

The first step is recognizing that your struggles might be ADHD. Many adults use self-screening tools like the Adult ADHD Self-Report Scale (ASRS-v1.1) developed by the World Health Organization. This 6-question screener can help you determine if a full assessment is warranted.

Common signs you might benefit from assessment:

• Consistent underachievement despite apparent capability

• Chronic disorganization and messiness

• Frequent job changes or relationship problems

• Difficulty managing finances or bills

• Feeling overwhelmed by daily tasks

• History of academic struggles despite intelligence

• Family member diagnosed with ADHD

Step 2: Speaking with Your GP

Book an appointment with your GP to discuss your concerns. Be prepared to:

• Describe specific symptoms and how they affect your daily life

• Explain impairment in multiple areas (work, home, relationships)

• Provide examples of childhood symptoms (ADHD is a lifelong condition)

• Mention any family history of ADHD

• Discuss how symptoms have persisted over time

What GPs can do:

• Rule out other conditions (thyroid problems, anxiety, depression, sleep disorders)

• Use screening tools like ASRS

• Refer you to specialist ADHD services if appropriate

• Provide information about NHS and private options

What GPs typically cannot do:

• Diagnose ADHD themselves (requires specialist assessment)

• Initiate ADHD medication (prescribed by psychiatrist)

• Provide long-term ADHD management without specialist input

Step 3: The Assessment Process

NHS Assessment:

• GP referral to adult ADHD specialist service

• Waiting times: Often 12-24 months (varies significantly by region)

• Assessment duration: 1-3 hours (sometimes split across sessions)

• Conducted by psychiatrist or specialist ADHD clinician

• Includes: clinical interview, symptom history, impairment review, childhood history, ruling out other conditions

• Uses diagnostic criteria: ICD-10 or DSM-5

Private Assessment:

• Book directly with private clinic (no GP referral needed)

• Waiting times: Typically 1-4 weeks

• Assessment duration: 1-2 hours

• Cost: £400-£800 for initial assessment

• Same diagnostic criteria as NHS

• Often includes same-day or next-day feedback

What Happens During Assessment?

A thorough ADHD assessment typically includes:

Clinical interview:

• Detailed symptom history from childhood to present

• Examples of how symptoms affect daily life

• Impact on work, education, relationships, self-esteem

• Medical and psychiatric history

Childhood information:

• ADHD symptoms must have been present before age 12

• School reports may be requested

• Questionnaires for parents or family members (if available)

Impairment assessment:

• Symptoms must cause significant impairment in at least one domain

• Examples: work performance, relationships, financial management, safety

Rule-out process:

• Other conditions that might explain symptoms (anxiety, depression, bipolar disorder, autism, thyroid issues, sleep apnea)

• Sometimes requires blood tests or other investigations

Diagnostic criteria:

• ICD-10 (used in UK NHS): Requires symptoms in multiple settings

• DSM-5 (used internationally): Requires 5+ symptoms inattention and/or hyperactivity-impulsivity

Adult ADHD Treatment Options in the UK

According to NICE Guideline NG87, adult ADHD treatment should be personalized and may include medication, psychological interventions, lifestyle strategies, or combinations thereof.

Medication: First-Line Treatment for Moderate to Severe ADHD

NICE recommends for adults (18+):

• Methylphenidate OR Lisdexamfetamine as first-line pharmacological treatment

• Medication is most effective when combined with psychological support

Medication effectiveness:

• Stimulants improve symptoms in 70-80% of adults

• Effects typically seen within 30-60 minutes

• Must undergo titration (12-16 weeks) to find optimal dose

Methylphenidate:

• Starting dose: 18mg once daily (long-acting)

• Maximum: 108mg daily

• Available as Concerta, Medikinet, Ritalin

Lisdexamfetamine:

• Starting dose: 30mg daily

• Maximum: 70mg daily

• Single daily dose, longer duration (10-13 hours)

Second-line option: Atomoxetine (non-stimulant) if stimulants ineffective or contraindicated

The Titration Process

Before reaching stable therapeutic dose, most patients undergo titration:

• Start with low dose

• Gradually increase (usually weekly)

• Monitor blood pressure, pulse, weight every 2 weeks

• Track symptoms and side effects

• Duration: 12-16 weeks (average 14 weeks)

• End with End of Titration Review

Non-Medication Treatments

Cognitive Behavioural Therapy (CBT) for ADHD:

• Mindfulness and meditation

• Organizational tools and systems

NHS vs Private Adult ADHD Treatment in the UK

One of the biggest decisions is choosing between NHS and private care.

• Long waiting times: 12-24 months common for assessment

• Limited availability (varies by region)

• Fewer appointment options

• Less flexible scheduling

NHS Right to Choose

The Right to Choose scheme allows you to request assessment with alternative NHS providers (like Psychiatry UK or ADHDnet) rather than waiting for local services. This can significantly reduce waiting times while maintaining free NHS treatment.

Benefits:

• Faster access (often 3-6 months vs. 12-24 months)

• Same NHS funding (free treatment)

• Specialist providers with ADHD expertise

• Often includes online options

Private Adult ADHD Treatment

Advantages:

• Less regulated than NHS

Typical costs:

• Initial assessment: £400-£800

• Titration appointments: £150-£300 each

Important: Shared Care Agreement Reality

GPs are not legally required to sign Shared Care Agreements. They may refuse if they feel burden is too great.

If GP refuses shared care:

• Psychiatrist continues prescribing and monitoring

• Consider changing to GP who accepts shared care

• Use NHS Right to Choose for alternative
