Can Concussions Lead to ADHD-Like Symptoms?

ByMy Patient Advice

Concussions and ADHD-like symptoms can often be confused, as both can cause difficulties with focus, memory, and behaviour. However, while ADHD is a neurodevelopmental disorder, concussions can lead to temporary symptoms that mimic those of ADHD. Understanding the differences is crucial for accurate diagnosis and treatment. 

After a concussion, individuals may experience post-concussive symptoms such as headaches, dizziness, and difficulty concentrating. These symptoms can affect attention and memory, leading to difficulties in school or work environments, which can resemble the inattention seen in ADHD. Additionally, cognitive issues such as poor concentration and slowed processing speed can occur following a concussion, further adding to the confusion.

Common Symptoms: Concussions and ADHD-like Symptoms 

Post-Concussive Symptoms

Following a concussion, symptoms like difficulty concentrating, irritability, and fatigue can appear similar to the inattentiveness and impulsivity seen in ADHD. However, these symptoms are typically temporary and related to the brain injury. 

Cognitive Issues 

Concussions can cause cognitive issues such as memory problems, slower thinking, and difficulty retaining information. These issues may resemble ADHD symptoms but are usually a result of brain injury rather than a lifelong attention disorder. 

Memory Problems 

Individuals recovering from a concussion may experience memory problems, which can mimic the forgetfulness and disorganisation often seen in ADHD. However, these memory issues should resolve as the brain heals. 

By recognising the differences between Concussions and ADHD-like symptoms, healthcare professionals can ensure the proper diagnosis and avoid unnecessary treatment for ADHD when the symptoms are caused by concussion-related brain injury.
