Personalized Ads Reveal Hidden Details About My Online Behavior and Interests

TikTok recently informed me I have ADHD based on my tendency to lose keys, procrastinate at work, and struggle with focus. To verify this claim, I sought opinions from qualified medical experts for their official diagnoses.

I cannot pinpoint exactly when advertisements began feeling too personal. The shift became clear only after realizing they seemed aware of private details I kept hidden. Looking back, my online behavior provided ample data for algorithms to analyze. When a topic interests me, I often conduct hundreds of Google searches within just a few days.

One week I researched pizza dough; the next, the Bayeux Tapestry. Then it was tinned fish. After exhausting written content on these subjects, I inevitably turned to YouTube, Instagram, or TikTok for more videos. Like most people, I usually ignored ads before finding desired content. Recently, however, they have felt unnervingly specific.

One commercial caught my attention a couple of months ago. It appeared filmed in a single phone take and felt like someone thinking aloud rather than a standard commercial. My cursor hovered near the 'Skip Ad' button but stopped mid-click. The speaker described losing focus to new fascinations while dishes piled up and unfinished tasks remained abandoned.

The advertisement promoted specially engineered music designed to improve concentration and attention spans. Matthew Wilcox saw this ad for focus-enhancing audio, which made him consider he might have ADHD himself. This marked the beginning of many products targeting my perceived personal shortcomings directly.

Another featured a grey-haired man reflecting on lifelong frustration and an inability to follow through on plans. The pitch promised that a 28-day plan for 'high-IQ brains' held the solution. By week four, he claimed transformation into the person his potential always suggested he could be.

The sales approach was irresistible. I began viewing my habit of diving into new ideas only to lose momentum differently. It was not just an explanation offered; it suggested change might be possible. Soon, I started examining my life through this new perspective entirely.

One memory stands out clearly from 2022 when I left a national newspaper job to cover the seafood industry for a trade publication. This seemed responsible: less time in London, a steadier pace, and better fit with a newborn baby at home. Instead, less than a year later, I was packing my desk after being fired, wondering how I failed so badly.

My instinct was simply to keep moving forward. I sought work, pitched stories, and tried maintaining momentum. Looking back now, that period appears frighteningly stressful. I supported an infant, missed out on a mortgage qualification, and had no clear future path.

Perhaps this explains why the advertisements resonated so strongly. They reframed disconnected frustrations as one coherent story effectively. As it turned out, I was not alone in these experiences. Healthwatch England, an independent patient advocacy group, states one in five people now use social media for health information. Increasing numbers also turn to AI chatbots for symptom advice.

Searching online for 'procrastination' or 'difficulty concentrating' quickly surfaces ADHD as a suggested explanation. In many ways, ADHD now occupies the space once held by OCD a decade ago: a clinical diagnosis steadily diluted into a personality trait.

Socially acceptable terms like "a bit OCD" once described simple preferences for order, but now ADHD serves as a catch-all phrase for impulsivity and distraction. The surge in online content about the condition is immense, driven by an ecosystem of creators who post short videos using catchy titles such as "Five signs you have ADHD." These clips encourage viewers to reinterpret everyday annoyances as medical symptoms one video at a time.

Influencers like Rich and Rox Pink, known collectively as @ADHDLove on Instagram, have amassed millions of followers by sharing their personal experiences with ADHD and autism. The potential reach for such content is enormous; NHS England estimates that approximately 2.5 million people in England may have the disorder, either diagnosed or not.

Professor Frankie Swords has raised alarms about this trend, stating that misinformation on social media poses "a real threat to public health." By March of this year, referrals for ADHD assessments exceeded 800,000, leaving over 230,000 individuals waiting more than two years for an appointment. In the absence of timely clinical attention, social media platforms and online businesses step in to offer both explanations and solutions.

As patients increasingly seek answers online before consulting a clinician, NHS leaders have grown worried about the quality of available information. Professor Swords recently warned that doctors are seeing patients who became convinced they had specific conditions after reading from "highly unreliable" internet sources. This often leads them to reject proven treatments in favor of unproven miracle cures.

The author questioned whether their own decades-long struggles represented a genuine neurodevelopmental disorder or merely the result of an effective marketing strategy. Admitting that even a skeptic like themselves was susceptible, they downloaded an app promising "sonic support tuned for ADHD brains" and paid £11.99 for it. For two days, they became an enthusiastic advocate for the product before forgetting about it entirely a week later. The more pressing question remains whether any medical reality exists beneath the digital noise.

Medically, ADHD is defined as a neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with daily functioning. Symptoms must have been present since childhood, occur across multiple settings, and cause significant impairment. Isolated incidents like forgetting keys or delaying chores do not constitute the disorder. No single video convinced the author they had ADHD; rather, it was the relentless accumulation of content that constructed a narrative where ordinary experiences appeared as clinical evidence.

Henry Shelford, chief executive of ADHD UK, argues that blaming social media alone is insufficient. He told the author that the deeper issue lies with an NHS struggling to meet demand for assessments. In just 12 months, the number of people awaiting a diagnosis without any contact from NHS services rose from around 79,000 to nearly 148,000. Shelford summarized the frustration by stating, "Being angry at misleading information on social media is a bit like being an old man angry at clouds.

In every corner of the internet regarding attention deficit hyperactivity disorder, there is valuable information mixed with absolute nonsense." This observation underscores a growing tension between digital self-help and professional medical advice. While some attribute the recent spike in referrals to fleeting social media trends, experts argue it represents decades of underdiagnosis finally meeting heightened public awareness. Regardless of the root cause, the strain on healthcare services remains undeniable. Into this void step platforms like TikTok, Google, and artificial intelligence tools such as ChatGPT.

When I recounted my own journey—the accumulation of videos leading to a sudden realization that unrelated life experiences formed a single narrative—Dr Chetna Kang, a consultant psychiatrist at Nightingale Hospital in London, immediately recognized the pattern. She warns that ADHD is increasingly marketed as an identity or even a "superpower" rather than a disorder causing genuine impairment. Online narratives often highlight creativity and entrepreneurial success while minimizing the disabling nature of the condition. By definition, she notes, ADHD must be severe enough to disrupt education, employment, and relationships.

Dr Kang points out that struggles with concentration, procrastination, planning, and time management are not exclusive to ADHD. Stress, anxiety, depression, and other mental health conditions can produce similar symptoms. Consequently, a specialist assessment evaluates severity, persistence, childhood history, and whether difficulties occur across different settings. However, this clinical nuance is not the only concern for her.

The more significant shift occurs before patients even enter her consulting room. Increasingly, individuals arrive convinced they already know what is wrong with them. Dr Kang worries that self-diagnosis creates an illusion of expertise regarding treatment. She has witnessed patients who have consumed friends' medication, purchased stimulants online, or experimented with drugs prior to receiving a formal evaluation. "I have observed people who turn up already fluent in the language of ADHD itself: 'I'm struggling to focus. I procrastinate. I have poor time-management,'" she says. These accounts often sound well-rehearsed, almost copied directly from diagnostic criteria.

Rather than starting with a diagnosis, Dr Kang's approach begins by addressing the person's specific difficulties. She asks patients to set aside their self-assigned labels and describe their top three struggles—specifically those that would most improve their quality of life if addressed. This careful, open-ended assessment is precisely what many struggle to access through the National Health Service or budget-conscious private providers. A consultant psychiatrist spends approximately 15 years training before practicing independently. The task involves distinguishing ADHD from dozens of other conditions that can look remarkably similar or overlap.

While a social media video or an AI chatbot can compare symptoms against a checklist, they cannot replace years of clinical experience. Reflecting on my own case after speaking with Dr Kang, I realized my life was not merely a story of unmanaged deficits. I had learned Japanese well enough to earn a degree in it, completed a master's in film studies, and made a living as a journalist for over a decade. Whatever difficulties I faced existed alongside achievements that required years of sustained effort. The question remains whether these accomplishments were simply masking an underlying condition.

Perhaps the data merely proved I was seeking a diagnosis that did not exist. I remain uncertain about my ADHD status, yet I have chosen to start the evaluation process regardless of long wait times. This algorithm proved remarkably skilled at convincing me to ask the question in the first place. Now I prefer hearing answers from independent clinicians rather than those whose livelihoods depend on selling a specific belief.
