Dispelling the myth: Late-onset ADHD

ADHD (Attention Deficit Hyperactivity Disorder) is a term that has seeped deeply into our collective consciousness, bringing with it a flurry of debates, misunderstandings, and myths. One such myth that has gained traction is the idea of late-onset ADHD, suggesting that individuals can develop ADHD later in life. However, the consensus among the scientific and medical communities is clear: ADHD is a neurodevelopmental disorder, which means that you are born with it.

Understanding ADHD

To better understand why late-onset ADHD is considered a myth, it's important to grasp what ADHD entails. ADHD is characterised by a pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development. It has three presentations:

  • Predominantly inattentive

  • Predominantly hyperactive-impulsive

  • Combined presentation

The neurodevelopmental nature of ADHD

A central aspect of ADHD is its classification as a neurodevelopmental disorder. This categorisation is crucial because it underscores that ADHD symptoms arise in early development, typically before the age of 12 years. These are not traits or behaviours that an individual acquires in adulthood but rather patterns that were seen in childhood.

Key points to consider

  1. Early development origins: Although ADHD is diagnosed mainly in children, it’s founded on the understanding that the brain's development (in utero) impacts behaviour patterns observed in ADHD.

  1. Persisting into adulthood: While ADHD symptoms can continue or be diagnosed in adulthood, this does not equate to the disorder suddenly emerging later in life. Adults diagnosed with ADHD likely had undiagnosed symptoms throughout their lives.

  1. Diagnosis challenges: Diagnosing ADHD in adults is complicated by the overlap of symptoms with other conditions, such as anxiety or depression, and the responsibilities and challenges of adult life, which can exacerbate or mimic ADHD symptoms.

  2. Misinterpretation of symptoms: What might seem like late-onset ADHD could often be attributed to situational stressors or other mental health conditions developing in adulthood, not ADHD developing de novo.

Conclusion

The narrative of late-onset ADHD, while perhaps stemming from a genuine place of seeking understanding, does not align with the current body of scientific evidence. ADHD symptoms can be noticed in childhood and persist into adulthood, but strategies on how to manage these can change.

If you or someone you know is struggling with symptoms similar to those of ADHD but did not experience these in childhood, it's advisable to seek a thorough evaluation from a healthcare professional. They can provide clarity on the symptoms and help discern their root causes, ensuring the right support and interventions are provided.
