PART 1: ADHD
ADHD is a neurodevelopmental disorder, not a situational difficulty with focus.
A valid diagnosis requires:
Symptom onset before age 12
Presence across multiple settings
Clear functional impairment
One of the most common errors in clinical practice is diagnosing ADHD based solely on subjective concentration difficulties, without establishing developmental history or ruling out mimics.
Conditions that frequently overlap or mimic ADHD include:
Anxiety disorders
Major depressive disorder
PTSD
Sleep disorders
Substance use disorders
Failure to differentiate these leads to misdiagnosis and inappropriate stimulant prescribing.
Clinically, ADHD is best understood as a disorder of performance regulation, not knowledge deficit; patients often know what to do but cannot consistently execute.

From my experience, one of the biggest challenges in diagnosing ADHD is recognizing that symptoms cannot be attributed to just situational factors or adult-onset issues. ADHD is a lifelong neurodevelopmental disorder, and symptoms must be present from childhood, typically before age 12. This means that when assessing a patient, it’s crucial to collect a detailed developmental history, including input from family members or old school records if possible. Another point worth emphasizing is the importance of distinguishing ADHD from conditions that mimic its symptoms such as anxiety, depression, PTSD, sleep problems, and substance use disorders. For example, anxiety can cause difficulty concentrating, but the underlying cause and treatment differ significantly from ADHD. Similarly, depression might reduce motivation and energy, which can be mistaken for inattentiveness. In clinical practice, ADHD is better understood as a disorder of performance regulation rather than a deficit in knowledge or intelligence. In other words, individuals often know what to do but struggle to consistently execute tasks, especially those that aren’t immediately rewarding or engaging. Dopamine dysregulation plays a role in this inconsistency. This explains why patients might focus well on interesting activities yet fail to maintain attention on routine or obligatory tasks. Finally, clear evidence of functional impairment in academic, occupational, or relational domains is essential for a valid diagnosis. Mild symptoms without real-life consequences should prompt clinicians to consider other explanations rather than diagnosing ADHD. This approach minimizes the risk of inappropriate stimulant prescribing and ensures patients receive tailored, effective interventions.
