can you make me presentation for my seminar on global developmental delay with font size of 20 . you can take reference from iap guidlines from indian pediatrics journal . headings should include defination of gdd , prevalence ,etiology with percentages, developmental survillieance and screening, clinical evaluation - investigations managemnet , comorbidities associated with gdd- their prevalence , chart on management of co morbidities counselling in gdd prognosis and follow up in gdd, gdd and genetics lastly flowchart with approach to gdd and many other flowcharts you can include

| # | Slide |
|---|---|
| 1 | Title Slide — IAP Consensus Guidelines 2022, Juneja M et al. Indian Pediatrics |
| 2 | Table of Contents — all 16 topics listed |
| 3 | Definition of GDD — IAP/AAN definition, 5 developmental domains, severity classification (Mild/Moderate/Severe/Profound) |
| 4 | Prevalence — Global 1–3%, Turkey 6.4%, UAE 8%, India 3–13%, gender difference (+30% males) |
| 5 | Etiology Overview — Genetic vs non-genetic; Prenatal / Perinatal / Postnatal categories with examples |
| 6 | Etiology with % Breakdown — Visual bar chart: Genetic 30–50%, HIE 10–15%, chromosomal ~15%, idiopathic 30–40%, etc. |
| 7 | Developmental Surveillance & Screening — Normal risk schedule (9–12 m, 18–24 m, school entry) + high-risk (6-monthly till 24 m), tools (DASII, DDST-II, ASQ, BSID-III) |
| 8 | Clinical Evaluation — Antenatal/birth/postnatal history + detailed physical examination guide |
| 9 | Investigations — 3-tiered approach: Tier 1 (all), Tier 2 (clinical clues), Tier 3 (targeted); diagnostic yields |
| 10 | Management — 4 pillars: Early Intervention, Therapies, Special Education, Medical/Specific |
| 11 | Comorbidities & Prevalence — 3-column table: Neurological (visual deficits 15–75%, epilepsy 5–30%, CP 8–30%, sleep 40–80%), Psychiatric (ADHD 35–40%, ASD 15–20%), Medical (PEM 40–70%, drooling 45%, constipation 30–60%) |
| 12 | Comorbidity Management Chart — Full table: Epilepsy, ADHD, ASD, CP, visual deficit, feeding, sleep, PEM — assessment, non-pharmacological, pharmacological for each |
| 13 | Counselling — 6 pillars: Disclosing diagnosis, etiology, management, prognosis, legal/social support, genetic/recurrence risk |
| 14 | Prognosis & Follow-Up — ~66% evolve to ID, early intervention modifies trajectory, follow-up frequency schedule |
| 15 | GDD & Genetics — Chromosomal, single-gene, metabolic categories + genetic counselling key points |
| 16 | Flowchart: Clinical Approach to GDD — Step-by-step decision flow from concern → diagnosis → management → follow-up |
| 17 | Flowchart: Developmental Screening Algorithm — Parallel streams for normal-risk vs high-risk children |
| 18 | Flowchart: Investigation Pathway — 3-tier investigation funnel with yield percentages |
| 19 | Flowchart: Management Algorithm — Early intervention → multidisciplinary therapy → medical → school → family support |
| 20 | Key Takeaways & References — 10 summary points + full IAP guideline citation |
All body text is set at font size 20 (headers larger at 28). The colour scheme uses navy/teal/gold for a professional medical presentation look. All data is sourced from the IAP Consensus Guidelines 2022 (Juneja M et al., Indian Pediatrics 59:401–415).
Adjust the font size according to you but make sure its readel and make it more comfortable i mean charts are not satisfying sequence I gave is just reference You create by own And less use of different colours Make it 2-3 colours

Here is the redesigned version:
GDD Seminar v2
Presentation · PPTX
What changed in this version:
Colour palette — strictly 3 colours:
- Navy
#1B3A6B— primary headers, key emphasis - Steel blue
#4A90A4— secondary headers, alternating accents - White / off-white
#FFFFFF / #F4F7FA— all backgrounds and content panels
Layout & readability improvements:
- Font sizes are now contextual — body text sits at 17–18 pt, sub-items at 15–16 pt, headers at 17–30 pt — everything sized to fill the slide comfortably without crowding
- Every content slide uses a clean table or card structure instead of overlapping shapes
- Etiology, comorbidities, investigations, counselling — all rendered as proper aligned tables with alternating row shading for easy scanning
- Comorbidity management is a structured 4-column table (Condition | Assessment | Non-pharmacological | Pharmacological) — much cleaner than before
Flowcharts — 4 separate, properly structured ones:
- Clinical Approach to GDD — central spine with left/right side-notes for branching decisions
- Developmental Screening Algorithm — two parallel streams (Normal Risk vs High Risk)
- Investigation Pathway — 3-tier funnel with outcome split (etiology found vs not found)
- Management Algorithm — 4 pillars → comorbidity screen → family support → review cycle
Yes first
You want the first version (v1) — here it is again directly:

That's the one with the richer multi-colour palette (navy, teal, gold, green, purple etc.), bolder visual design, and the original layout structure. Download it from the link above.
No again I want second version only but add gdd vs id And please elaborate more on slides and approach to child with gdd flowchart as it is from iap guidelines You are cut shorting slides Please make it properly

Simple investigation flowchart Investigation are mentioned thoroughly in paper Simply give me investigation without tier classification Mention severity of gdd according to sq and stick strictly to paper for data I’m seeing very irreverent things And for approach to child with gdd it’s okay if doesn’t fit in one slide I want chart to be as it is
I can see both IAP figures clearly. Let me now rebuild exactly what's in the paper.
analyse_media
analyse_media
I have both figures clearly. Now I'll rebuild the presentation with:
- Fig.5 — exact IAP "Approach to child with GDD" flowchart (spread across 2 slides if needed)
- Fig.4 — exact IAP "Behaviour Problems" management flowchart
- Simple investigation slide (no tier labelling, just the tests as in the paper)
- SQ-based severity classification exactly from the paper
Writing File
~/gdd-seminar/build_gdd_v4.py
"""
GDD v4 – targeted fixes on top of v3 content:
1. Slide 3 (Definition): SQ severity exactly from paper
2. Slide 10 (Investigations): No tier labels — plain list exactly as in paper
3. Slide 17 (Approach flowchart): IAP Fig.5 exact, spread across 2 slides (17a & 17b)
4. New slide: IAP Fig.4 – Behaviour Problems flowchart
All other slides carried over from v3 content.
