Inattentive ADHD is often characterised by distractibility, difficulty focusing, and forgetfulness. However, children with this subtype might not exhibit the hyperactive or disruptive behaviours typically associated with ADHD, which can make diagnosis more challenging. This can lead to the misdiagnosis of quiet children who may display internalising symptoms, such as daydreaming or withdrawn behaviour, rather than externalising hyperactivity.

The Internalising Presentation of ADHD

Quiet children often have an internalising presentation of ADHD, where symptoms are less outwardly visible but still significantly impact their ability to function. These children may struggle with attention regulation and executive function, but do not disrupt the classroom or social environment in obvious ways. Instead, they may appear to be daydreaming, disengaged, or “too quiet.” This can cause their symptoms to go unnoticed or be misunderstood as laziness, shyness, or a lack of motivation.

Teachers and parents may not recognise the signs of inattentive ADHD because the child’s behaviour is quieter and less disruptive than more stereotypical ADHD symptoms. As a result, the child may be misdiagnosed with other issues like anxiety or depression or simply overlooked altogether.

Hidden Symptoms and Misdiagnosis

Since inattentive ADHD can involve hidden symptoms, such as difficulty retrieving data, organising tasks, or remembering instructions, quiet children often internalise their struggles. This internalisation can lead to emotional distress, which is sometimes mistaken for other conditions, such as anxiety or learning disabilities. Without proper recognition of the ADHD symptoms, these children may receive incorrect or delayed treatment.

Conclusion

Quiet children with inattentive ADHD are at risk of misdiagnosis due to the subtle nature of their symptoms. Early intervention is key to ensuring accurate diagnosis and appropriate support for their unique challenges.
