The Link Between ADHD, Autism, and Compulsive Behaviours: Shopping, Spending, and Eating Disorders

Have you ever bought something on a whim, only to regret it later? Or perhaps you’ve found yourself eating more than you planned, even when you weren’t hungry. These behaviours might seem like simple bad habits, but for some people, they’re signs of something deeper.


For those with ADHD and autism, impulsive shopping, overspending, and certain eating habits are more than just quirks—they’re ways of managing how their brains work. So let’s see how these behaviours are connected and what they really mean.


People with ADHD often struggle with impulse control. This means they might buy things on a whim because it feels good in the moment. The brain’s reward system in ADHD works in unique ways, so finding quick ways to feel good—like shopping—can become a habit.


This impulsive shopping can lead to problems like accumulating debt or feeling guilty afterwards. But it’s important to remember that this isn’t about being irresponsible; it’s a way of trying to manage how the brain feels.


Autistic people might also have issues with shopping or spending, but for different reasons. Instead of acting on impulse, they might shop as part of a routine or because it fits into a special interest. For instance, someone might buy the same type of item repeatedly because it’s comforting or part of their routine.


This is less about chasing a quick reward and more about finding comfort in predictability and routine. So, while the behaviour might look similar, the reasons behind it can be quite different from those in ADHD.


Both shopping and eating can be ways to “chase dopamine,” the brain’s feel-good chemical. In ADHD and autism, the brain might not release dopamine as easily, so people might seek it out through other means, like shopping sprees or certain eating habits.


For example, some might binge eat or restrict their eating to feel in control or to get that dopamine rush. These behaviours are ways to manage emotions or anxiety, much like impulsive shopping.


So, what can be done? Recognising these behaviours is the first step. Therapy, such as Cognitive Behavioural Therapy (CBT), can help people understand why they’re doing what they do and find healthier ways to cope.


Mindfulness and learning to manage emotions can also be powerful tools. For some, medication might help balance the brain’s reward system, reducing the urge to shop impulsively or eat compulsively.


Support from friends, family, or professionals can make a big difference too. It’s important to remember that these behaviours aren’t about being weak or undisciplined—they’re signs of how someone’s brain is wired, and with the right support, they can be managed.


If any of this sounds familiar, know that you’re not alone. Impulsive shopping, overspending, and eating issues can be challenging, but they’re also manageable. Understanding that these behaviours are linked to ADHD, autism, and how the brain seeks rewards can be the first step towards making positive changes.


If you see yourself in these words, consider reaching out for help. It might be helpful to connect with a professional who understands these challenges. You can check out the directory of Neuro-affirmative practitioners to find someone experienced in offering the right kind of support. Whether it’s talking to a therapist, joining a support group, or simply chatting with a friend, there’s support out there for you. You deserve to feel good—without the stress that can come from chasing those feel-good moments in unhealthy ways.
