A well-known British comedian recently described a life-changing moment: after decades of severe depression, joy returned within seconds once he learned he has adult ADHD. He called the experience transformative, even magical. The personal story aligns with a growing body of research showing many adults carry undiagnosed ADHD and how it intersects with chronic depression.
In Thailand, mental health is increasingly prioritized, with rising rates of depression and anxiety especially in Bangkok’s urban environment. Many adults experience low mood and motivation that are often misread as personal fault. Global research indicates a notable portion of adults treated for depression may actually have undiagnosed ADHD, a condition once considered only a childhood issue but now recognized as a lifelong challenge.
Recent studies suggest up to a quarter of adults treated for major depression meet ADHD criteria, and many go undiagnosed for years. Adult ADHD can present differently than in children, including persistent procrastination, difficulty sustaining attention, impulsivity, and emotional volatility. These symptoms can be mistaken for or mask depression and anxiety.
A leading psychiatrist at a major Bangkok hospital notes that awareness of adult ADHD in Thailand remains limited. Patients who do not respond fully to antidepressants or therapy may have underlying ADHD. Accurate diagnosis and personalized treatment can be life-changing.
The comedian’s experience highlights how a misdiagnosis or undiagnosed comorbidity can prolong suffering, while a correct diagnosis offers relief. He had tried numerous depression treatments—medication, therapy, mindfulness, lifestyle changes—without lasting results until ADHD was identified. Experts say the moment of clarity can be as impactful as any treatment, reducing lifelong frustration when people understand their brain.
International research supports this: psychoeducation about ADHD can significantly improve mood and functioning, sometimes as powerfully as medication. It helps dispel stigma and replace self-blame with a clearer, science-based view of one’s brain.
In Thai society, family ties and a culture of joy coexist with pressure to conform to social expectations. Adult ADHD is rarely screened in local clinics, leaving many people with depression or anxiety untreated for an additional diagnosis. Health professionals advocate routine ADHD screening for patients with chronic or treatment-resistant depression, noting that therapy alone may be less effective if ADHD remains unaddressed.
Access to specialist care is improving in Thailand, with major hospitals offering adult ADHD clinics. Yet waitlists and costs remain barriers, particularly in rural areas. Public health officials are expanding training for primary care doctors to recognize adult presentations of neurodevelopmental conditions. There is growing demand for research on how undiagnosed ADHD affects workplace productivity and overall mental health burden in the country.
Depression and anxiety are expected to remain major non-communicable causes of disability among Thailand’s working-age population in the coming decade. Recognizing ADHD as a contributing factor could shift prevention and treatment strategies, helping people regain control of their lives. Health professionals urge a move from stigma toward science-based care and tailored interventions.
Historically, some Thai families turn to spiritual or herbal remedies before psychiatric care. While these approaches provide comfort, they can delay diagnosis. As brain science advances, integrating traditional wisdom with modern medicine offers new paths for holistic well-being.
Looking ahead, experts anticipate stories like the comedian’s to spur more research, better screening tools, and outreach to adults who grew up when ADHD was poorly understood. Thailand’s health authorities are evaluating the prevalence of treatment-resistant depression that ADHD could explain, while universities are introducing neurodiversity-focused courses to train clinicians.
For readers facing long-standing depression or frustration with standard treatments, consider discussing ADHD with a mental health practitioner. Validated screening tools are available in major hospitals and can be accessed in Thai language. Early recognition can open doors to specialized care and improve daily functioning.
The broader takeaway is not a single cure but a more accurate understanding of one’s brain. Recognizing adult ADHD within the context of depression can guide better, brighter futures for countless Thai families.
