Can Poor Sleep Mimic ADHD and Cause Overdiagnosis? 

Yes, sleep problems vs. ADHD misdiagnosis is a growing concern, especially in children. Sleep deprivation or insomnia can cause symptoms that closely resemble ADHD, such as inattention, irritability, and difficulty focusing. When children or adults experience poor sleep, their ability to concentrate and manage daily tasks is often impaired, leading to behaviours that can be misinterpreted as ADHD symptoms. 

Many children, particularly those with disrupted sleep patterns, may struggle with attention and self-regulation. However, when sleep issues are the root cause, the focus should be on improving sleep, not immediately jumping to an ADHD diagnosis. If these sleep problems are not addressed, they can easily lead to misdiagnosis and unnecessary treatment. 

How Sleep Issues Can Mimic ADHD 

Here’s how sleep problems contribute to ADHD misdiagnosis: 

Sleep deprivation  

Lack of sleep affects concentration, memory, and mood, leading to behaviours similar to those seen in ADHD. 

Insomnia  

Chronic sleep difficulties can result in daytime fatigue, hyperactivity, or irritability, which can look like paediatric ADHD assessments. 

Behavioral overlap  

Children with sleep disorders may appear inattentive, restless, or emotionally dysregulated behaviours commonly associated with ADHD. 

In conclusion, for sleep problems vs. ADHD misdiagnosis, it’s important to rule out sleep issues before jumping to conclusions about ADHD. Proper sleep hygiene and addressing underlying sleep disorders can help improve these symptoms and reduce the need for unnecessary interventions.
