In a large-scale study published in The British Journal of Psychiatry (January 23, 2025), researchers analysed data from over 30,000 adults (18+) diagnosed with ADHD, compared with a control group of over 300,000 participants. The study revealed a concerning association between ADHD and reduced life expectancy, with some reports indicating a decrease of up to 11 years. This finding has significant implications for individuals considering or receiving ADHD assessment and treatment. This article delves into the complex interplay between mental and physical health in the context of ADHD and offers strategies to manage these risks and enhance overall well-being.
The Impact of Mental Health on Life Expectancy
The impact of significant mental health conditions on life expectancy is well-established within the medical community. Studies conducted by Oxford University psychiatrists have shown that serious mental illnesses can reduce lifespan by 10 to 20 years, a reduction comparable to or even greater than that associated with heavy smoking. This finding has reinforced the need for integrated care models that address both mental and physical health. Consequently, quality improvement initiatives have been implemented across services to mitigate cardiometabolic risk factors, particularly in individuals prescribed psychotropic medications, adhering to established standards of care.
The Complexity of Mental Health and ADHD:
The rise of social media can sometimes oversimplify complex mental health conditions, including ADHD and Autism Spectrum Disorder (ASD). In reality, these neurodevelopmental conditions require thorough diagnosis and long-term management due to their chronic nature. Conditions like depression and anxiety contribute significantly to the burden of disease and have high relapse rates (39%-72%). Adults with ADHD are also more likely to experience co-occurring conditions, which may be directly related to their ADHD or present as separate issues. It's crucial to acknowledge that not all services and professionals involved in ADHD diagnosis possess the comprehensive understanding necessary to address these complex interactions between physical and co-existing mental health conditions.
ADHD diagnosis in social media
Research conducted examining TikTok and Attention-Deficit/Hyperactivity Disorder Study of Social Media Content Quality found that approximately half of analysed TikTok videos about ADHD contained misleading information. This underscores the pervasive nature of health misinformation on social media and its potential impact on clinical practice.
The recent shift away from fact-checking by major social media platforms further exacerbates this issue. Remember, popularity does not equate to accuracy; social media platforms prioritise engagement through social proof. Therefore, both consumers and clinicians should remain vigilant and consult with healthcare professionals for reliable health information.
Why Might ADHD Be Associated with Lower Life Expectancy?
The authors of the study noted that adults with diagnosed ADHD have a reduced life expectancy, likely due to modifiable risk factors and unmet support and treatment needs related to both ADHD and co-occurring mental and physical health conditions. They also cautioned that their findings, based on data from diagnosed adults, may not generalise to the broader population of adults with ADHD, the majority of whom remain undiagnosed.
Contributing Factors to Reduced Life Expectancy in ADHD
Several factors contribute to the potential link between ADHD and reduced life expectancy:
- Diagnostic and Treatment Gaps: More recently ADHD diagnoses are sometimes made and treated outside of traditional medical settings, meaning individuals may not receive comprehensive medical oversight. NHS ADHD specialist services are often under-resourced and overstretched, and there is limited emphasis on training GPs and psychiatrists in managing neurodevelopmental conditions.
- Increased Risk of Addictions: Individuals with ADHD have a higher risk of developing substance use disorders, which significantly increases the risk of mental health relapse and negatively impacts physical health.
- Eating Disorders: Eating disorders, including restrictive disorders like anorexia nervosa and binge-eating disorders like bulimia nervosa, are among the most severe mental health conditions, associated with higher mortality rates.
- Sleep Disorders: Over half of individuals with ADHD experience co-occurring sleep disorders, such as narcolepsy, which can have significant health implications.
- Risk-Taking Behaviours: Increased impulsivity and inattention can lead to both intentional and unintentional risk-taking behaviours, including accidents.
- Missed Medical Appointments: Inattentive symptoms, impaired executive functioning, and memory difficulties can cause individuals with ADHD to miss routine physical health check-ups.
- Social and Financial Stressors: Difficulties managing relationships, divorce, breakups, financial stress due to overspending, frequent job changes, and relocation can all contribute to chronic stress, negatively impacting health.
- Medication Considerations: While some studies suggest ADHD medication may improve life expectancy, others indicate a potential increased risk of cardiovascular events. Regardless of medication status, regular engagement with healthcare professionals and adherence to follow-up appointments for medication management and monitoring are crucial.
ADHD care imbalance in women vs men
Research indicates a reduced life expectancy for individuals with diagnosed ADHD: between 4.5 and 9 years for men and between 6.5 and 11 years for women.
This suggests a potentially greater impact on women, contrasting with the general UK population, where women typically have a higher life expectancy. In 2020–2022, UK life expectancy at birth was 78.6 years for men and 82.6 years for women, a decline from 79.3 years for men and 83.0 years for women in 2017–2019.
This disparity raises concerns about ADHD care for women, potentially indicating differences in access to care, possible higher rates of co-occurring conditions, misdiagnosis, or other contributing factors. Therefore, the ADHD assessments for women should be particularly thorough lasting a couple of hours and focusing on ADHD symptoms specific to women, physical health, hormonal balance, menopause and other relevant factors.
What if ADHD is not managed comprehensively?
One potential outcome is misdiagnosis, leading to treatment for conditions like depression, anxiety, or personality disorders. While these treatments may alleviate some symptoms, they do not address the underlying ADHD. Accurate diagnosis is crucial, as adults with ADHD alone (without comorbidities) typically experience a good prognosis, with patients reporting significant improvements in up to 80% of cases.
The presence of co-occurring conditions, particularly personality disorders, may be denied by some individuals due to historical stigma. In cases where a comorbid condition exists independently of ADHD, it is essential that it be addressed concurrently with the neurodevelopmental condition.
Understanding that ADHD symptoms and life stressors can fluctuate is key. This means that treatment and support, including non-medication strategies, may need to be adjusted over time. ADHD is a lifelong condition, so it's important to view management as an ongoing process rather than a one-time fix.
Taking Control and Improving Outcomes
While the research on ADHD and life expectancy can be concerning, it's crucial to remember that many of the associated risks are modifiable. By prioritizing comprehensive care, including:
- Accurate Diagnosis and Treatment: Seeking assessment and treatment from qualified medical professionals.
- Addressing Co-occurring Conditions: Recognising and managing co-existing mental and physical health issues.
- Lifestyle Modifications: Focusing on healthy lifestyle choices, such as regular exercise, a balanced diet, and good sleep hygiene.
- Consistent Medical Follow-Ups: Attending regular medical check-ups and adhering to treatment plans.
Effective ADHD management extends beyond diagnosis and medication titration. Given its implications for various aspects of physical and mental health, a holistic approach is essential. Recent evidence of decreased life expectancy underscores the importance of seeking detailed and comprehensive care for ADHD symptoms.
Understanding the role of psychiatrists in managing ADHD
Psychiatrists, as medically qualified doctors, possess a thorough understanding of physical health, psychological factors, and the symptomatology of various mental health conditions, including ADHD. Psychiatrists in the UK acquire competencies in a range of therapeutic approaches, in addition to pharmacological interventions. Some choose to develop specialised expertise in various areas such as addictions or psychotherapy.
It is important to note, however, that even if an individual has a pre-existing ADHD diagnosis, a psychiatrist will typically conduct an independent assessment to gain a comprehensive understanding of their specific circumstances, psychological profile, presenting symptoms, physical health status, and support requirements. This assessment is undertaken to ensure the most effective and personalised care and should not be perceived as a dismissal of the prior diagnosis.
Key takeaway: Psychiatrists provide personalised ADHD care, which may or may not include medication depending on individual needs. Starting to work with a psychiatrist for your ADHD symptoms typically requires an assessment.
Starting your ADHD assessment and treatment well
The delivery of medical services, especially in the field of mental health, is complex due to the inherent human element. Prior to selecting an ADHD assessment, careful consideration should be given to the following factors: firstly, the duration of the assessment (ranging from one to two hours or more). Given the chronic nature of ADHD, a comprehensive evaluation is advisable to minimise potential future uncertainties. Secondly, the professional qualifications of those involved in the assessment and subsequent treatment should be evaluated. This may include medical doctors, psychologists, specialist nurses, pharmacists, or other allied health professionals. Ultimately, the most suitable choice will depend on your individual requirements.
