Dyslexia Duo Podcast Episode 85 - Dr. Tiffany Hogan

The Dyslexia Duo:  Dr. Tiffany Hogan on Developmental Language Disorder (DLD), Dyslexia, and Language Comprehension   On the Dyslexia Duo podcast, hosts Melissa Dean and Aimee Rodenroth interview speech-language pathologist and literacy researcher Dr. Tiffany Hogan about the relationship between dyslexia and developmental language disorder (DLD). Dr. Hogan describes her training and research, including analyses from the NIH-funded Iowa Study that followed children from kindergarten through 12th grade and helped determine DLD prevalence. She explains that dyslexia primarily involves difficulty reading words accurately and fluently, while DLD involves difficulties learning vocabulary, grammar, and discourse, with a high but not one-to-one overlap (about 50–80%). The conversation covers early indicators such as late talking (fewer than 50 words and no two-word combinations at age two), the need to directly screen language (e.g., sentence repetition, story retell), overlap with ADHD, and the importance of systematic, explicit instruction for both word reading and language comprehension, including MTSS approaches. Hogan shares resources including DLDandMe, Empower DLD, RADLD, and her See Hear Speak podcast.   00:44 Introducing Dr Tiffany Hogan 01:42 Her Path Into Research 03:11 The Iowa Longitudinal Study 04:38 Dyslexia Versus DLD 06:39 Overlap And Real Examples 10:23 Two Pillars Of Reading 12:19 Early Signs And Late Talkers 14:57 Building Language At Home 18:45 Beyond Phonological Deficits 21:02 Screening For DLD In Schools 23:44 ADHD Comorbidity And Systems 27:05 Tumbleweed Reading Tools 27:25 Dyslexia Services Spotlight 28:25 Research on Dual Deficits 30:11 Language Curriculum Results 31:09 Training and Fidelity 34:15 MTSS for Language 35:56 Why DLD Gets Missed 37:12 Integrating Language in Therapy 40:55 Partnering With SLPs 43:11 Parents Next Steps 44:38 Best DLD Resources Online 47:14 Lightning Round and Wrap 49:47 Final Sign Off
