What is Aphantasia?
Ever tried recreating a sunset in your mind, but all you see is a blank canvas? If yes, you might be experiencing a phenomenon called Aphantasia. This fascinating condition is characterized by an inability to form mental images.
People with Aphantasia can’t visualize a friend’s face or a favorite place. Even trying to imagine a simple object like an apple might prove to be a challenge. It’s like trying to paint a picture without any colors or brushes.
However, it doesn’t mean people with Aphantasia are impaired. They can think about things, remember facts, and carry on with their lives normally. They just lack the ability to ‘see’ or ‘hear’ things in their mind’s eye or ear.
Interestingly, some people with Aphantasia have reported being able to dream visually. This suggests that while their conscious mind might struggle to form images, their unconscious mind could still have this ability.
Aphantasia is still a relatively new and understudied field within neuroscience. Hence, there are many unanswered questions. For instance, what causes Aphantasia? Is it genetic, or does it develop over time?
Moreover, could there be a connection between Aphantasia and other cognitive conditions, like Attention Deficit Hyperactivity Disorder (ADHD)? This is a question that researchers are currently exploring.
The Aphantasia-ADHD Connection: Myths and Facts
Often, the world of neuroscience presents us with intriguing puzzles, and one such enigma is the potential connection between Aphantasia and ADHD. Aphantasia, a condition where one can’t visualize imagery, and ADHD, a disorder characterized by issues with attention and hyperactivity, seem worlds apart. Yet, some fascinating threads suggest a possible link. Let’s dive into the myths and facts.
Myth 1: All individuals with ADHD have Aphantasia
Fact: While there’s some overlap, it’s not a universal rule. Having ADHD doesn’t necessarily mean you’ll have Aphantasia. These are distinct conditions with unique diagnostic criteria.
Myth 2: Aphantasia causes ADHD
Fact: There’s no solid evidence to validate this claim. While it’s possible for someone to have both Aphantasia and ADHD, it doesn’t imply that one causes the other.
Myth 3: Aphantasia and ADHD are linked genetically
Fact: As of now, research does not suggest a clear genetic correlation between Aphantasia and ADHD. More thorough studies are needed to conclusively determine this.
The Verdict: Is there a Link?
The current understanding of both Aphantasia and ADHD is still evolving. While anecdotal evidence suggests some individuals may possess both conditions, it’s crucial to remember that correlation does not equal causation. The scientific community continues to explore this captivating intersection, and as the research advances, we can anticipate more definitive answers.
Remember, every individual’s experience with these conditions is unique. If you or someone you know is grappling with Aphantasia or ADHD, seeking professional help is always the best course of action.
More research is needed to determine if there is a causal relationship between aphantasia and ADHD.

The Common Thread: The Brain’s Executive Function
Both ADHD and Aphantasia appear to be linked to the brain’s ‘executive functions‘. These are a set of cognitive processes including working memory, cognitive flexibility, and inhibitory control, which manage how, when, and in what order certain actions are performed.
Aphantasia: A Different Perspective
Studies on Aphantasia have suggested it might be related to the brain’s executive functions. Some researchers believe that individuals with Aphantasia struggle with tasks that require them to manipulate information in their mind’s eye, a key component of working memory.
ADHD: A Closer Look
Similarities crop up when considering ADHD. This condition is often associated with impairments in executive functions, particularly working memory. Individuals with ADHD often struggle with tasks requiring them to juggle multiple pieces of information at once.
The Role of Memory in Aphantasia and ADHD
Memory plays a pivotal role when discussing Aphantasia and ADHD. But, just how interconnected are these concepts?
For those with Aphantasia, memory works differently. Instead of visualizing past events, they rely on factual or semantic memories. It’s akin to reading a book, where they recollect events, places, and people based on facts, not mental images.
ADHD sufferers often have problems with working memory. They may forget tasks, struggle with following instructions, or lose track of conversations. It’s like trying to juggle multiple balls in the air, but constantly dropping one or two.
Some theorists propose a potential link between Aphantasia and ADHD because of their shared impact on memory. Both conditions alter the way memory works, albeit in different ways. However, it’s crucial to mention that this connection is largely theoretical at this point and requires more scientific exploration.
It is possible that aphantasia and ADHD share some underlying neurological mechanisms.

How common is Aphantasia?
It’s believed to affect approximately 1-3% of the population, though accurate data is still hard to come by. This is partly because many people with Aphantasia may not even realize they experience the world differently, often assuming that phrases like ‘counting sheep’ or ‘picturing a beach’ are purely metaphorical.
Discovering Aphantasia
The term ‘Aphantasia’ was only coined in 2015, making it a relatively new area of scientific exploration. Neurologist Adam Zeman at the University of Exeter was the first to use the term, following a study of 21 patients who lost their ability to visualize after brain injuries. This hints at the complexity of the condition, as it’s not something we’re born with, but something that can develop due to various factors.
Prevalence in Men versus Women
Interestingly, it seems more men report having Aphantasia than women, but it’s unclear why this might be. It could be due to societal norms influencing how we perceive and report our internal experiences.
Studies show there may be more of a connection to Autism
In this study, several tests were conducted to compare three groups: people with aphantasia (who can’t form mental images), people with hyperphantasia (who have extremely vivid mental imagery), and a control group (average people).
The tests included Trails A and B (which measure attention and cognitive flexibility), verbal fluency tests (which measure cognitive function and language ability), and the Hospital Anxiety and Depression Scale (HADS) to assess anxiety and depression levels. The results showed no significant differences between the three groups in these areas. This means that having aphantasia or hyperphantasia doesn’t seem to affect these cognitive abilities or mental health aspects.
However, when it came to the Autism Quotient measure (a test that measures the presence of traits associated with the autism spectrum), there was a significant difference. The aphantasia group scored higher than the control group, suggesting that people with aphantasia may have more traits associated with autism. However, the hyperphantasia group did not significantly differ from the control group in this measure.
In conclusion, this study suggests that aphantasia might be associated with a higher presence of autism-related traits, but more research is needed to fully understand this relationship. It’s important to note that this doesn’t mean people with aphantasia have autism, but rather that they may share more traits common in the autism spectrum compared to the general population.
The Future of Aphantasia and ADHD Research
Here are some recent studies related to Aphantasia and ADHD:
- The prevalence of aphantasia (imagery weakness) in the general population by C. Dance, A. Ipser, J. Simner (2021): This study aimed to clarify the prevalence of aphantasia in the general population. The researchers screened a cohort of undergraduate students and found that 4.2% had aphantasia. They then screened a new sample of people at an online crowdsourcing marketplace, again finding that approximately four percent (3.6%) had aphantasia. Full Text
- What is the Link Between Mental Imagery and Sensory Sensitivity? Insights from Aphantasia by C. Dance, J. Ward, J. Simner (2021): This study investigates the relationship between sensory imagery and sensory sensitivity. The researchers found that people with aphantasia reported not only lower imagery, but also lower sensory sensitivity. Full Text
Conclusions
So, is there a relationship between Aphantasia and ADHD? The truth is, we’re still figuring it out. More research is necessary to draw definite conclusions.
Aphantasia and ADHD are both complex conditions that affect the brain, but they manifest in very different ways. Aphantasia refers to the inability to visualize mental images, while ADHD is characterized by inattention, impulsivity, and hyperactivity.
Some studies suggest there might be a connection. For example, individuals with ADHD often struggle with visualization strategies, a core issue for those with Aphantasia. This suggests a potential overlap.
However, it’s important to remember that correlation doesn’t necessarily mean causation. Just because these conditions may coexist in some individuals doesn’t mean one causes the other.
In essence, while there may be intriguing intersections between Aphantasia and ADHD, a direct link remains unconfirmed. We must be patient as science unravels this intriguing puzzle.
Let’s keep an open mind and stay curious. Who knows what we might discover in the future?
