If your child has been diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) and also struggles with bedwetting, you are not alone in noticing a link. While bedwetting is common for many children, studies have shown that it is more prevalent in children with neurodevelopmental disorders including ADHD compared to the general population. A 2020 study of 100 children presenting for enuresis treatment found that approximately 40% were also diagnosed with ADHD.1
Dealing with one condition is hard enough, and managing both ADHD and primary nocturnal enuresis (PNE) can be particularly challenging for both the child and their family. Addressing this link with a healthcare professional can lead to a more effective and tailored treatment plan.
The Connection Between ADHD and Bedwetting
The exact reasons for the increased rate of bedwetting in children with ADHD are complex and thought to involve several factors that affect the central nervous system, many of which also affect all children with PNE.
1. Altered sleep arousal patterns
Children with ADHD frequently experience disruptions in sleep regulation and arousal response.2 Studies show that many have higher arousal thresholds, meaning they are less likely to wake when their bladder is full during the night.
2. Bladder capacity and voiding dysfunction
Children with ADHD and enuresis have been found to exhibit higher rates of dysfunctional voiding and reduced functional bladder capacity compared with ADHD children who do not wet the bed.3 This suggests a physiological component affecting bladder control during sleep.
3. Behavioural and attentional challenges
Executive-function difficulties associated with ADHD can interfere with adherence to behavioural therapy for enuresis — for example, following evening fluid guidelines, completing toilet routines and consistently responding to bedwetting alarms. Clinical guidance notes that inattention and impulsivity may reduce the effectiveness of routine-based treatment approaches.4
The existence of a connection between ADHD and PNE is supported by medical evidence, which highlights the need for a comprehensive approach to diagnosis and treatment.
Management and Treatment Approaches
Because there is a connection, an integrated approach to management is often necessary. Addressing one condition may sometimes improve the other.
If your child is using a bedwetting alarm, consistency is key for success. However, children with ADHD may find it particularly challenging to maintain the routine required for the alarm to work effectively over the necessary weeks and months. If the process is causing distress or not working after a consistent trial, it may be time to discuss the challenges with your doctor.
Your doctor will be able to consider the impact of your child’s ADHD on any treatment choice and recommend an approach that provides the best chance of sustained improvement.
Talking to Your Doctor
If your child is aged 6 or older and bedwetting continues to affect their sleep, confidence, or daily life, please speak to your doctor. This is especially important when other factors, like ADHD, are present.
Your doctor can explore all the possible influences including bladder function, overnight urine production, and genetics, and discuss the evidence-based treatment options available to support you in finding an approach that works for your child.
