Still not ADHD? Here’s what you do next – long-term strategies

So, your ADHD assessment came back with a negative diagnosis. This doesn’t mean that what you’re feeling isn’t real, so a good long-term plan is to work on improving your symptoms or understanding where they come from.

This page will dive deeper into: 

  • what healthy adjustments you can make to your lifestyle, 
  • who can offer additional support if you feel like you need it,
  • and how to use this experience as an opportunity for self-discovery and personal development.

Focus on symptom management


Even without a diagnosis, identifying your challenges can help you address them one by one and implement coping strategies that can help you manage your symptoms.

Healthy lifestyle habits can also improve your overall well-being. We’re sure you’ve read similar advice many times, but small changes can truly make a huge difference. So this is what research says helps with ADHD:

Exercise icon

  • Exercise: Both single sessions of exercise at moderate intensity and long-term periods of exercise have been shown to improve ADHD symptoms related to working memory and executive functions, like following instructions or completing complex tasks. Cardio exercises like running, cycling, swimming, rope skipping, or ball sports have been shown to have beneficial effects on ADHD symptoms.[1] 

Balanced diet plate

  • A balanced diet:  Research reveals that a healthy diet that prevents ADHD should aim to balance deficits of: [2]
    • Magnesium: try including foods like almonds, black beans, dark chocolate, or spinach in your diet.
    • Zinc: foods like oysters, beef, chickpeas, and cashews are good sources of zinc.
    • Iron: red meat, organ meats, lentils, tofu, seafood, spinach and beans, are all high in iron, but be careful to add vitamin C to your diet to increase the absorption of iron especially from plant-based foods.
    • Vitamin D: sunlight exposure is the best (natural) source of vitamin D, but it can also be found in certain supplements and foods like fatty fish, eggs, red meat, and liver.
    • Omega-3 Fatty Acids: found in oily fish, oysters, flaxseeds, chia seeds, and walnuts.

Sleep icon

  • Healthy sleep routines: Many people with ADHD have sleep issues and struggle to follow a healthy sleep routine. Tools like alarms and apps that help with organisation and establish a daily, consistent routine can help. Cognitive behavioural therapy for insomnia (CBT-I) has also shown moderate benefits.[3]

  • Reducing alcohol intake: One study has shown that ADHD symptoms improved substantially for 115 patients with substance use disorder who didn’t consume alcohol for one year.[4]

H2: Seek further professional guidance


If you still feel like you need professional help, there are further steps you can take to identify any underlying problems that are causing your symptoms. 

First, you can discuss your concerns and symptoms with your GP. You can go to the same GP who made a specialist referral for you (if this is the case) or ask to see a different one if you feel like you need a second opinion. They can help you explore other potential causes and refer you to specialists if needed.

Next, you can consider seeing a therapist or counsellor to address any underlying emotional or mental health concerns. Counselling can help teach you coping strategies and help you better understand your symptoms, whether they’re ADHD-related or not. You can ask your GP if this can be helpful for you.

You can also consider a neuropsychological evaluation. This type of evaluation looks at how your brain works in certain areas that deal with concentration, memory, and problem-solving. It can help identify your brain’s strengths and weaknesses and how these may affect your day-to-day life.

Or specialised testing. Depending on your symptoms, there may be specialised testing available to rule out other conditions like dyslexia, coordination disorders, Tourette’s syndrome, or autistic spectrum disorders.

H2: Embrace self-discovery

Everyone’s unique, and so are our brains. So you can use this experience as an opportunity for self-reflection and personal growth. No matter the official diagnosis or lack thereof, your mind is your own, and so it’s worth exploring and understanding.

Self-exploration can help you identify your strengths and weaknesses and find ways to leverage them.

This will be different for everyone, but here’s a practical example:

If you struggle with long, unstructured tasks but thrive in fast-paced, creative environments, you can use this in work by choosing roles that involve quick thinking and variety, like event planning or creative work.

Become an advocate for your own well-being and continue to seek answers and support. Seek therapy, coaching, or support groups, which can be useful for your mental well-being.

Continue to track your symptoms and any changes you notice over time. Keep a simple log of:

  • The times of day or situations when symptoms worsen or improve
  • Any changes in mood, energy, sleep, or focus
  • Any coping strategies you’ve tried and how they worked
  • Major life events or stressors

Tracking your symptoms can become incredibly helpful if you decide to revisit a diagnosis later or explore other possibilities. It also helps you understand yourself more deeply over time.

Key takeaways

  • A “not ADHD” result doesn’t mean your symptoms aren’t real and don’t deserve attention.
  • Review your assessment report and speak with your clinician to fully understand the outcome.
  • Explore other possible causes like anxiety, autism, and sleep issues.
  • Consider keeping a symptom journal and building a detailed medical history for future assessments or second opinions.
  • Focus on managing your symptoms and using this experience for self-reflection and personal growth.
