🌱 BIG IDEA (Key Teaching Point)
Disabilities and learning difficulties can develop at different stages:
- 🧬 Before birth (prenatal)
- 👶 During birth (perinatal)
- 🌍 After birth (postnatal)
👉 They can come from genetic, medical, or environmental causes
👉 Sometimes the exact cause is known
👉 Sometimes it is unknown
🧬 1. BEFORE BIRTH (PRENATAL CAUSES)
This is when a baby is developing in the womb.
🧠 Possible causes:
🧬 Genetic and chromosomal conditions
- Down syndrome (extra chromosome 21)
- Fragile X syndrome
- Angelman syndrome (UBE3A gene changes)
- Other inherited or spontaneous gene changes
🌱 Brain development differences
- Differences in early brain cell development and connectivity
- Can affect communication, movement, and learning
🤰 Pregnancy-related factors
- Infections during pregnancy (e.g. rubella, CMV, toxoplasmosis, Zika)
- Exposure to alcohol, drugs, or harmful chemicals
- Poor nutrition (e.g. low folic acid levels)
- Maternal health conditions (e.g. diabetes, obesity)
🧠 Autism example (important clarification)
Research shows:
- Autism likely begins before birth during brain development
- It is strongly linked to genetic and neurodevelopmental factors
- It is not caused by parenting or later trauma
👶 2. DURING BIRTH (PERINATAL CAUSES)
This is around the time of birth.
⚠️ Possible causes:
- Oxygen deprivation (birth asphyxia)
- Premature birth (especially very early)
- Low birth weight
- Physical birth complications
- Brain injury during delivery
🧠 Important understanding:
- Not all birth complications cause disability
- Some can increase risk of developmental differences
- Outcomes depend on severity, timing, and treatment
🌍 3. AFTER BIRTH (POSTNATAL CAUSES)
This is after the baby is born, during early childhood development.
⚠️ Possible causes:
- Severe infections (e.g. meningitis, encephalitis)
- Head injuries or accidents
- Exposure to toxins or poisoning
- Severe untreated medical conditions
- Lack of oxygen after birth (rare but possible)
🧠 4. DEVELOPMENTAL DISABILITIES (GENERAL UNDERSTANDING)
According to public health guidance (e.g. CDC-type definitions):
Developmental disabilities:
- Begin during the developmental period (before birth to early childhood)
-
Affect:
- Learning
- Communication
- Movement
- Daily living skills
They may be:
- Mild
- Moderate
- Severe
- Or require lifelong support
🧬 5. EXAMPLES OF CONDITIONS (LINKING MODULE IDEA)
🧠 Down Syndrome
- Caused by an extra chromosome (trisomy 21)
- Occurs at conception
- Not inherited in most cases
- Causes learning disability and possible health conditions
- Every person is different
🧠 Cerebral Palsy
- Often linked to brain injury before, during, or shortly after birth
- Can affect movement, muscle control, and coordination
- Severity varies widely
🧠 Angelman Syndrome
- Caused by changes in the UBE3A gene (chromosome 15)
-
Affects:
- Movement
- Speech
- Sleep
- Behaviour
-
Often involves:
- Limited speech
- Flapping movements
- Ataxia (movement difficulty)
- Seizures
- High levels of happiness/excitability
🧠 Autism Spectrum Disorder (ASD)
- Neurodevelopmental condition
- Begins in early brain development (before birth)
-
Affects:
- Communication
- Social interaction
- Sensory processing
- Behaviour and routines
- Not caused by vaccines, parenting, or single trauma
🧠 6. IMPORTANT PROFESSIONAL MESSAGE
👉 Disabilities are not always caused by one single event
They may involve:
- Genetics
- Brain development
- Medical events
- Environmental exposure
- Unknown factors
⚖️ 7. KEY TEACHING POINT: TIMING DOES NOT EQUAL BLAME
A very important message for learners:
👉 “When a disability begins is not the same as what caused it.”
👉 “Most disabilities are not caused by anyone doing something wrong.”
This helps reduce:
- Stigma
- Blame on parents
- Misunderstanding in care and education
💬 8. YOUR PERSONAL INSIGHT (VERY IMPORTANT ADDITION)
What you said is historically very important:
-
In earlier decades (especially UK late 60s–70s):
- Autism and developmental conditions were poorly understood
- Many children were misdiagnosed or missed completely
- Causes like oxygen deprivation were often discussed differently
- Awareness was very limited in schools and healthcare
👉 This helps learners understand:
- Why diagnosis has improved today
- Why some adults were missed
- Why awareness matters now
🧠 9. EASY LEARN SUMMARY
🟢 Disabilities can happen:
- Before birth (genes, pregnancy factors)
- During birth (oxygen, complications)
- After birth (injury, illness)
🟢 Causes can include:
- Genes
- Health conditions
- Environment
- Infection
- Unknown reasons
- Neglect
🟢 Key idea:
👉 Everyone is different and needs different support
🎯 FINAL KEY MESSAGE (FOR YOUR BOOK)
“Disabilities can begin at different stages of life and development. Understanding when and how they may arise helps reduce stigma, improves awareness, and support better care. Most importantly, no one is to blame for a disability.”
