The maths topic has touched some emotions I think. Totally understandable, we all have been there either through struggle or euphoria associated with algebra and parentheses. Incredibly, science told us that a significant proportion of people with ADHD either struggle with maths or have dyscalculia. Mainly visible in inattentive type (ADD, which now has been removed from DSM, so I am not sure why we still use it). How do we go about learning numbers then?
Scientists were puzzled by mathsy brains for a long time. Einstein's brain was cut and studied to understand where his genius came from. Functional magnetic resonance imaging (fMRI) studies revealed structural and functional differences between the brains of mathematical experts and subjects without that expertise, The specific discrepancies have not been found yet, however, scientists discovered that when presented with meaningful and meaningless mathematical statements, the experts' brains were activated in the parietal and frontal regions. This has not happened in the nonmathematical group. What is interesting, those regions of the brain lie outside of the areas where language processing happens. Learning mathematical concepts requires the creation of neural pathways that allow for the acquired numerical knowledge to be absorbed. This means, that repetition to solidify the knowledge is key.
As ADHD brains are different it is difficult to find a universal strategy for learning mathematics. I have received many requests for some tips on how to study mathematics. Below you can download a comprehensive guide which is an interactive PDF with links to other resources and courses.
You can also download a Mathsy planner with a minimalist design. I find it helpful to keep up with my tasks because they are loosely scheduled, which means I can still complete something even when it is last minute.
All sources which I used to write this short introduction and the guide can be found in the PDF.
