Myth #31 #DyslexiaAwarenessMonth:" #Dyslexia/#reading impairment is rare!" NOT TRUE! While the exact prevalence of #dyslexia/reading impairments depends on many factors (e.g., the definition, the language, diagnostic practices), we can say with great certainty that..1/7

... #dyslexia/#reading impairments are not rare. Let's take a look at the numbers: Yesterday @NAEYC released a new report showing that 65% of 4th graders are not reading proficiently. We know that the estimates of #dyslexia range from 3-12% but vary across countries but.. 2/7

..prevalence rates for #dyslexia are difficult to estimate due to differences in the definitions used, how & at what ages individuals are identified, criteria for diagnosis, & orthographic transparency (the degree of consistency between spelling &sound) plays a role as well! 3/7

Current estimates in English-speaking countries typically range between 5-10%, with greater variance in US than UK estimates. Estimates as high as 10% of individuals in some Chinese societies, about 7% of individuals in Japan when examining reading of Kanji.....4/7

In addition to 5-10% in English/Asian countries, prevalence estimates are about 5% in Germany, 3-4% in Italy & Spain. Most importantly, all of these individuals benefit from early identification & evidence-based interventions regardless of the cause of their #reading problems 5/7

This is the last myth post from @GaabLab (find all here: gaablab.com/dyslexia-myths) & a few myths were not addressed yet. For example: Retention as an intervention (😖) or the myth of the 'late bloomers' Anything else that we missed? We'll address those in the next few weeks! 6/7

Finally, I want to thank everyone for raising #Dyslexia Awareness this #DyslexiaAwarenessMonth! Together we can make a big difference #untileverychildcanread! Keep up the good work out there!
