What fMRI Shows About Working Memory Networks in ADHD 

ADHD working memory fMRI studies have revealed key differences in how the brain processes and stores information. These scans show that individuals with ADHD often display reduced activity in the prefrontal cortex, a region essential for working memory. This underactivation may explain many of the cognitive deficits associated with ADHD, including forgetfulness, poor organisation, and difficulty following multi-step instructions. 

When engaged in tasks that require holding or manipulating information, people with ADHD tend to show altered neural activation patterns. These changes are often most visible in the dorsolateral prefrontal cortex and parietal lobes, suggesting that ADHD affects both the storage and control components of working memory. Importantly, fMRI research provides insight into the biological basis of these challenges, helping move the conversation away from behavioural blame. 

Common Symptoms Tied to Working Memory Deficits 

Working memory problems in ADHD are linked to a number of functional difficulties. Here’s how these symptoms present and can be supported: 

Forgetfulness and Mental Disorganisation 

Tasks are easily forgotten or completed incorrectly. This is tied to poor activation in the prefrontal cortex. CBT can help by teaching memory aids and routines, while medication may enhance dopamine signalling to improve cognitive focus. 

Difficulty Holding Information During Tasks 

Struggles with following instructions or mental maths often stem from disrupted neural activation. Stimulants can improve communication between relevant brain regions, while executive function coaching offers practical strategies.
