Understanding the Link Between ADHD and Brain Fog
Written on
Chapter 1: Defining Brain Fog
What exactly is brain fog? While it lacks a formal medical classification, this term effectively captures a range of experiences that can be challenging to articulate. Brain fog is often described as a feeling of disconnection—not to be confused with dissociation. Individuals experiencing brain fog may struggle with forming coherent thoughts, finding the right words, memory lapses, and overall mental cloudiness.
Brain fog is frequently linked to various conditions, including Celiac Disease, hypermobility spectrum disorders, depression, and notably, ADHD. While this discussion focuses on ADHD, it’s essential to recognize that brain fog does not necessarily indicate the presence of ADHD or any of the aforementioned disorders.
Temporary brain fog can stem from fatigue, cognitive overload, and numerous other factors. However, those with ADHD might not always connect their symptoms to this phenomenon, which is the central aim of this exploration. It's important to note that scientific research on this topic is still in its infancy, as the term "brain fog" is relatively new and hasn’t been widely accepted by the medical and psychological communities.
A Personal Anecdote
In 2009, I found myself in a Chapters bookstore (now known as Indigo), trying to locate a specific book. After identifying the title on a computer terminal, I was unable to find its location within the store. Seeking assistance from an employee, I showed them the title on the screen, only to be pointed to the location that was right in front of me. Embarrassed, I thanked them and hurried off to find the book. This incident stands out as a vivid example of brain fog in my life, although I’ve certainly encountered many similar moments.
Section 1.1: The Causes of Brain Fog in Individuals with ADHD
The primary culprits behind brain fog seem to be cognitive overload and challenges with executive functioning. Cognitive overload occurs when the influx of stimuli surpasses our brain's capacity to process and retain information, making it difficult to filter out distractions. This leads to confusion and a lack of clarity in thought.
Neurodivergent individuals, particularly those with ADHD, often struggle with executive functioning, which includes working memory. Working memory is crucial for transferring information from short-term to long-term storage and for making connections between new and existing knowledge. When our brains are overwhelmed, it becomes increasingly difficult to make these connections, leading to feelings of fogginess.
Section 1.2: The Impact of Slow Processing Speed
Some neurodivergent individuals experience slow processing speed (SPS), which is common in Autism, ADHD, and certain learning disabilities. SPS is not indicative of intelligence; rather, it describes how quickly one can receive, comprehend, and respond to information. Individuals with SPS may need more time to process incoming stimuli, which can exacerbate feelings of cognitive overload.
Chapter 2: Strategies for Managing Brain Fog
For me, brain fog tends to arise during periods of illness (often related to Celiac Disease), fatigue, poor nutrition, or mental exhaustion. To combat brain fog, consider the following strategies:
- Medication (as prescribed by a healthcare professional)
- Maintaining a balanced diet
- Regular exercise
- Taking both mental and physical breaks
- Reducing commitments to manage cognitive load
- Ensuring sufficient sleep
- Addressing other underlying health issues
In the short term, I find that fresh air and caffeine are quite effective. A cup of coffee enjoyed outdoors or during a leisurely walk often helps to clear my mind.
As previously noted, various conditions can contribute to or exacerbate brain fog, including nutritional deficiencies like low iron anemia. If you’ve addressed these factors and continue to experience significant brain fog, I recommend consulting your healthcare provider for further investigation.

The video "ADHD: Brain Fog (Hypoactivity)" explores the nuances of brain fog and hypoactivity in those with ADHD, further illuminating this complex issue.
