MICROCEPHALY – A COMPREHENSIVE GUIDE By Physio360 – Best Physiotherapy & Neuro Rehab in Chennai

 What is Microcephaly?

Microcephaly is a neurological condition in which a baby’s head circumference is significantly smaller than expected for their age and sex. It occurs due to impaired brain development during pregnancy or early infancy.

✔ The brain fails to grow normally

✔ Head size falls below the 3rd percentile

✔ Can be present at birth or develop later

It is a rare condition, but its impact can range from mild to severe depending on the underlying cause.

Types of Microcephaly

1️⃣ Congenital (Primary)

✔ Present at birth

✔ Caused by abnormal brain development during pregnancy

2️⃣ Acquired (Secondary)

✔ Develops after birth

✔ Brain stops growing due to injury, infection, or metabolic issues

Causes of Microcephaly

Microcephaly can result from a combination of genetic and environmental factors:

Genetic Causes.

✔ Chromosomal abnormalities (e.g., Down syndrome)

✔ Gene mutations

Prenatal Causes.

✔ Infections (Zika virus, rubella, CMV, toxoplasmosis)

✔ Exposure to alcohol, drugs, toxins

✔ Severe malnutrition during pregnancy

✔ Reduced oxygen supply to the fetal brain

Postnatal Causes

✔ Brain injury

✔ Severe infections

✔ Metabolic disorders

Signs & Symptoms

The severity varies widely, but common features include:

Primary Feature

✔ Abnormally small head size

Associated Symptoms

✔ Developmental delay (speech & motor)

✔ Poor coordination and balance

✔ Seizures

✔ Intellectual disability

✔ Feeding difficulties

✔ Vision and hearing problems

Clinical Features (Important for Physiotherapists)

✔ Delayed milestones (rolling, sitting, walking)

✔ Hypotonia or hypertonia

✔ Poor postural control

✔ Impaired motor planning

✔ Reduced balance and coordination

These children require early neurodevelopmental rehabilitation.

Diagnosis

✔ Head circumference measurement (growth charts)

✔ Prenatal ultrasound (during pregnancy)

✔ MRI / CT scan for brain structure

✔ Genetic testing if needed

Treatment & Medical Management

No cure to increase brain size

✔ Treatment focuses on symptom management and functional improvement

Medical Care

✔ Anti-seizure medications

✔ Nutritional support

✔ Multidisciplinary approach

Role of Physiotherapy in Microcephaly

6

Goals of Physiotherapy

✔ Improve motor development

✔ Enhance balance & coordination

✔ Promote functional independence

✔ Prevent deformities

Key Physiotherapy Interventions

🔹 Neurodevelopmental Therapy (NDT)

✔ Improves posture and movement patterns

🔹 Sensory Integration Therapy

✔ Enhances sensory processing

🔹 Balance & Coordination Training

✔ Improves gait and functional mobility

🔹 Strengthening Exercises

✔ Builds muscle control

🔹 Functional Training

✔ Sitting, standing, walking activities

Early Intervention is KEY!

✔ Brain plasticity is highest in early childhood

✔ Early therapy improves outcomes significantly

✔ Helps the child achieve maximum independence

Early rehab = Better quality of life

Complications

✔ Intellectual disability

✔ Epilepsy

✔ Behavioural issues

✔ Growth delays

✔ Social and learning difficulties

Prevention Tips

✔ Proper antenatal care

✔ Avoid alcohol, drugs, and toxins during pregnancy

✔ Vaccination against infections

✔ Good maternal nutrition

Prognosis

✔ Mild cases → Near-normal life possible

✔ Severe cases → Lifelong support required

Each child is unique, and outcomes vary greatly.

Final Takeaway

Microcephaly is a complex neurological condition, but with early diagnosis, structured rehabilitation, and consistent physiotherapy, children can achieve meaningful improvements in function and independence.
