I know next to nothing about intervention methods designed for dyscalculia, or 'dyslexia with numbers', as I have heard it colloquially referred to (considering how obscure the term seems to be compared to its language-related twin). I have also read that dyslexia and dyscalculia often occur in conjunction, and both seem to affect the population at equal rates. Yet I can find far more literature and neurological research on dyslexia than on dyscalculia.
Is there a reason for this? And what do we know about dyscalculia from a neurological standpoint, as well as a treatment standpoint? (By 'neurological standpoint', I mean what do we know about neurological causes and/or areas of the brain that appear to be affected in those with dyscalculia)
