Microcephaly

Microcephaly means a baby’s or child’s head is smaller than expected for their age and sex. Doctors measure the head with a soft measuring tape and compare the number to standard growth charts. If the head size (also called occipito-frontal circumference, OFC) is more than 2 standard deviations below the average (often below the 3rd percentile), it is called microcephaly. If it is more than 3 standard deviations below average, it is called severe microcephaly.

Microcephaly is a measurement-based diagnosis. When a baby’s head size is more than 2 standard deviations below the average (about below the 3rd percentile) for age and sex, doctors call it microcephaly. When it is more than 3 standard deviations below average, it is sometimes called severe microcephaly. A small head usually means the brain had less growth during pregnancy or early infancy. That smaller brain volume can affect learning, movement, speech, vision, hearing, and seizures, but some children with mild microcephaly can develop near typically, especially if the cause is limited and there are no other brain problems.

The head grows as the brain grows. A small head often means the brain has fewer cells or less growth than usual. Sometimes the child can still develop normally, especially in mild or familial cases, but often there are developmental delays, learning difficulties, or other neurologic problems. The outlook depends on the cause and how severe the size difference is.

 A flexible, non-stretch tape is placed above the eyebrows, around the largest back part of the head (the occipital bump), making a level circle. The measurement is done three times, and the largest number is recorded to get the most accurate result. Doctors then plot it on a chart for the child’s age and sex and track it over time to see how fast the head grows.

How microcephaly happens

The brain grows rapidly in pregnancy and early childhood. Brain size depends on making new brain cells (neurogenesis), moving them to the right places (migration), and building connections (synapses and myelin). Problems at any step—because of genes, infections, toxins, poor blood flow, or early skull fusion—can lead to a smaller brain and therefore a smaller head. In some families, naturally small heads run in the family but development is normal; this is different from microcephaly caused by disease.

Types of microcephaly

1. Primary (congenital) microcephaly.
   Present at birth. The head is already small in late pregnancy or at delivery. This often relates to genetic causes or problems during early brain formation.

2. Secondary (postnatal) microcephaly.
   The head size may be near normal at birth but does not grow as expected after birth. This happens when there is brain injury, infections, malnutrition, or metabolic problems after delivery.

3. Isolated microcephaly.
   The child has a small head but few or no other physical abnormalities. It can be familial, where parents or relatives also have small head sizes and normal development.

4. Syndromic microcephaly.
   The small head occurs with other features—such as facial differences, limb changes, heart defects, or eye problems—because of a wider genetic syndrome.

5. Proportional microcephaly.
   The whole body is small (short length/height and low weight), and the head is small in the same proportion. This suggests overall growth restriction.

6. Disproportionate microcephaly.
   The head is small but the body size is closer to normal. This pattern points more strongly to a brain-specific issue (genetic, infection, toxin, or other brain disorder).

7. Microcephaly with craniosynostosis.
   The skull bones fuse too early, leaving no space for brain growth. The head shape can look abnormal, and the head circumference stays small. This is a surgical condition.

8. Microcephaly due to placental insufficiency/IUGR.
   The fetus does not get enough oxygen and nutrients in the womb, leading to poor growth, including the brain and head.

9. Microcephaly due to teratogens.
   Harmful substances (like alcohol or certain drugs) disturb brain development, causing a smaller head and brain.

10. Microcephaly after hypoxic-ischemic injury.
    Low oxygen to the brain around birth or early infancy injures brain tissue; later, the head fails to grow normally.

Causes of microcephaly

1. Genetic primary microcephaly (e.g., ASPM, WDR62 gene variants).
   Changes in single genes that control brain cell production make the brain smaller from the start.

2. Chromosomal disorders (e.g., Trisomy 13, 18; rare forms of 21).
   Extra or missing chromosome material changes overall development, including the brain.

3. Syndromic genetic conditions (e.g., Smith-Lemli-Opitz, Seckel).
   These include multiple body differences plus a small head because many body systems are affected.

4. Congenital Zika virus infection.
   Zika can damage developing brain tissue in pregnancy, often causing severe microcephaly and calcifications.

5. Congenital cytomegalovirus (CMV).
   CMV damages the developing brain, leading to hearing loss, calcifications, and a small head.

6. Congenital toxoplasmosis.
   This infection from parasites (often from undercooked meat or cat feces) can injure fetal brain tissue.

7. Congenital rubella (rare where vaccination is high).
   Rubella in early pregnancy can cause brain, eye, and heart problems with microcephaly.

8. Congenital varicella (chickenpox) or herpes infections.
   These viruses can disrupt brain development if severe and early in pregnancy.

9. Fetal alcohol spectrum disorders.
   Alcohol is toxic to developing brain cells, causing smaller brain volume and learning problems.

10. Certain medications in pregnancy (e.g., valproic acid, high-dose isotretinoin).
    Some drugs can interfere with brain formation if taken at sensitive times in pregnancy.

11. Severe maternal malnutrition or micronutrient deficiency.
    Lack of key nutrients limits fetal brain growth, leading to a small head.

12. Maternal phenylketonuria (PKU) not controlled.
    High phenylalanine levels in the mother are toxic to the fetus, causing microcephaly and heart defects.

13. Maternal uncontrolled thyroid disease (especially severe hypothyroidism).
    Thyroid hormones support brain development; severe deficiency can reduce brain growth.

14. Placental insufficiency and intrauterine growth restriction (IUGR).
    Poor placental blood flow starves the fetus of oxygen and nutrients; brain growth slows.

15. Perinatal hypoxic-ischemic encephalopathy (HIE).
    Low oxygen around birth can injure brain tissue; later, head growth lags.

16. Craniosynostosis (premature skull suture fusion).
    Early closure of skull joints limits space for a growing brain, causing a small head.

17. Metabolic disorders (e.g., mitochondrial disease, organic acidemias).
    Brain cells cannot make energy correctly, leading over time to smaller brain volume.

18. Neurodegenerative disorders (various rare conditions).
    Brain cells are lost over time, so the head stops growing as expected.

19. Radiation or heavy metal exposure (e.g., high radiation, lead, mercury).
    Toxic exposures destroy developing brain cells, leading to microcephaly.

20. Severe postnatal malnutrition or chronic illness.
    In early life, poor nutrition or chronic disease slows brain and head growth, causing secondary microcephaly.

Symptoms and signs

1. Small head size compared with other babies of the same age and sex.
   This is the most obvious sign and often the reason for evaluation.

2. Slow head growth over time.
   Repeated measurements show the head not keeping up with the curve on growth charts.

3. Developmental delay (motor).
   Late rolling, sitting, crawling, or walking because brain pathways are delayed.

4. Language delay.
   Late babbling, first words, and sentence building; understanding may also be slower.

5. Learning difficulties.
   Trouble with memory, attention, or problem-solving in preschool and school years.

6. Seizures.
   Abnormal brain electrical activity can cause staring spells, jerking, or loss of awareness.

7. Abnormal muscle tone.
   Muscles may be too tight (spastic) or too floppy (hypotonic), affecting posture and movement.

8. Poor coordination and balance.
   Clumsy movements, tremors, or trouble with fine motor tasks like picking up small objects.

9. Feeding and swallowing problems.
   Babies may cough, choke, or tire easily during feeds; weight gain can be slow.

10. Hearing problems.
    Children may not respond to sounds or speak late because they cannot hear well.

11. Vision problems.
    Poor tracking, strabismus (crossed eyes), or reduced vision due to optic nerve or brain issues.

12. Behavioral differences.
    Irritability, hyperactivity, autistic features, or trouble with self-regulation.

13. Sleep problems.
    Difficulty settling, frequent waking, or irregular sleep cycles.

14. Short stature or low weight (especially in proportional microcephaly).
    The whole body is small, not just the head.

15. Facial or body differences (in syndromic cases).
    Certain dysmorphic features may be present, pointing to a specific syndrome.

Diagnostic tests doctors use

(Grouped into Physical Exam, Manual/Bedside Assessments, Lab & Pathological, Electrodiagnostic, Imaging. Each item includes what it is and why it helps.)

A) Physical examination

1. Head circumference (OFC) measurement and Z-score.
   A soft tape measures head size. The number is plotted on age- and sex-specific charts to see if it’s < −2 SD (microcephaly) or < −3 SD (severe). This is the foundation of diagnosis.

2. Serial head growth velocity.
   Repeating the measurement over weeks or months shows whether the head is catching up or falling further behind, distinguishing congenital from postnatal microcephaly.

3. Cranial sutures and fontanelle exam.
   Gentle finger palpation checks whether skull joints are open (normal) or fused early (craniosynostosis), which alters management and may need surgical input.

4. Whole-body growth and neurological exam.
   Measuring length/height and weight shows if microcephaly is proportional. A detailed neuro exam looks at tone, reflexes, strength, coordination, and vision/hearing behaviors.

B) Manual / bedside assessments

5. Ages & Stages Questionnaire (ASQ) or similar screening.
   A parent-completed tool that flags early delays in communication, gross motor, fine motor, problem-solving, and personal-social areas.

6. Bayley Scales of Infant and Toddler Development.
   A structured one-on-one test that provides standard scores for cognitive, language, and motor skills, helping set therapy goals.

7. Bedside feeding and swallow assessment.
   Clinicians watch a baby feed, looking for sucking, coordination, choking, or fatigue. Results guide feeding therapy or safety studies.

8. Family head-size measurements (parents/siblings).
   Measuring parents’ OFC can reveal familial small head size with normal development, which changes prognosis and testing plans.

C) Laboratory and pathological tests

9. Chromosomal microarray (CMA).
   Looks for small gains or losses of DNA across the chromosomes (copy-number changes) linked to syndromic microcephaly.

10. Targeted gene panel or whole-exome/whole-genome sequencing.
    Searches for single-gene variants (e.g., ASPM, WDR62 and others) that cause primary microcephaly or broader syndromes.

11. Congenital infection testing (TORCH and region-specific).
    CMV PCR on saliva/urine, toxoplasma IgM/IgG, rubella serology, and—based on exposure—Zika PCR/serology. These identify treatable or counseling-relevant infections.

12. Metabolic screening panel.
    Plasma amino acids, acylcarnitine profile, urine organic acids, and sometimes lactate/pyruvate look for inborn errors of metabolism that present with microcephaly.

13. Thyroid function tests (TSH, free T4) and maternal PKU assessment if indicated.
    Detects treatable endocrine causes in the infant and checks maternal phenylalanine exposure history for counseling.

14. Heavy metal levels (e.g., lead) and other toxin screens as needed.
    Identifies preventable toxic exposures that can harm brain growth.

D) Electrodiagnostic tests

15. Electroencephalogram (EEG).
    Records brain electrical activity to confirm seizures and look for background slowing that indicates brain dysfunction.

16. Brainstem auditory evoked responses (BAER).
    Measures the hearing nerve’s response to clicks to detect hearing pathway problems, which are common in infection-related cases.

E) Imaging tests

17. Cranial ultrasound (through the fontanelle).
    A quick, bedside scan for infants with open soft spots. It can show ventricles, bleeds, or large structural differences without radiation.

18. MRI of the brain (with diffusion; spectroscopy when available).
    The best picture of brain structure. It can show abnormal development patterns (like lissencephaly, migration defects), white-matter injury, or calcifications, helping pinpoint cause and prognosis.

19. CT scan of the head (selected cases).
    Used when bone detail is needed (e.g., craniosynostosis) or when MRI is not available; it involves radiation, so it’s used judiciously.

20. Prenatal ultrasound and fetal MRI (during pregnancy).
    These detect small head size before birth, assess brain structure, and guide delivery planning and family counseling.

Regenerative” or immune-oriented therapies

Key point: There are no approved stem-cell or regenerative drugs for microcephaly. The items below are research concepts or used in other conditions; they should only be considered in registered clinical trials with ethics oversight.

1. Umbilical cord blood–derived cells
   Function/Mechanism: Potential to release growth factors and anti-inflammatory signals; theoretical neuroprotection. Dose: Not established for microcephaly.

2. Mesenchymal stromal cells (MSC) or exosomes
   Function: Paracrine signaling to reduce inflammation, promote repair. Mechanism: Cytokines/exosomes; experimental. Dose: Not established.

3. Neural progenitor cell transplantation
   Function: Attempt to replace or support neural cells. Mechanism: Engraftment and circuit support; animal/early research only.

4. Erythropoietin (EPO) as neuroprotective agent
   Function: Studied in preterm brain injury; not established for microcephaly. Mechanism: Anti-apoptotic, pro-angiogenic.

3. Vagus nerve stimulator (VNS) implant
   Why: For drug-resistant epilepsy to reduce seizure frequency.

4. Orthopedic procedures (e.g., tendon lengthening, hip stabilization)
   Why: Correct contractures or hip dysplasia to improve comfort and mobility.

5. Cochlear implant or advanced hearing surgery
   Why: For significant sensorineural hearing loss to improve access to language.

(Strabismus surgery may also be considered when eye alignment interferes with vision.)

---

Prevention strategies

1. Preconception folic acid (typically 400–800 µg/day; higher doses if advised).

2. Rubella vaccination before pregnancy (confirm immunity).

3. Prevent infection exposure (CMV hygiene, safe food handling for toxoplasma, mosquito precautions in Zika regions).

4. Avoid alcohol and illicit drugs entirely in pregnancy.

5. Avoid high-mercury fish and environmental toxins (follow local guidance).

6. Tight control of maternal diabetes and thyroid disease before and during pregnancy.

7. Manage maternal PKU with a strict diet before conception and during pregnancy.

8. Adequate maternal nutrition (protein, iron, iodine, choline, DHA).

9. Avoid unnecessary radiation/teratogenic medicines (review meds with clinician pre-pregnancy).

When to see a doctor

• Your baby’s head size is not growing or is below the 3rd percentile.

• You notice seizures, unusual spells, or developmental regression.

• Feeding problems, choking, or poor weight gain.

• Loss of skills, new weakness, or persistent vomiting.

• Concerns about vision, hearing, or sleep that do not improve.

• You are planning a pregnancy and have questions about infections, medications, or supplements.

What to eat and what to avoid

For children with microcephaly (with clinician and dietitian input):

• Focus on: calorie-dense, nutrient-rich foods; soft or puréed textures if chewing is hard; safe thickened liquids if advised; regular protein; fruits/vegetables; whole-milk yogurt/cheese if tolerated.

• Consider: DHA sources (oily fish appropriate for age/mercury limits), fortified cereals, and prescribed supplements when labs are low.

• Avoid: choking hazards; forced feeding; excess juice/sugary drinks; unpasteurized foods; fad supplements without guidance.

• If failure to thrive: plan high-calorie recipes, frequent small feeds, or tube-feeding per team.

For people planning pregnancy (prevention focus):

• Eat: folate-rich foods (leafy greens, legumes) + prenatal vitamins; iodine (iodized salt), iron if low, choline (eggs), DHA (low-mercury fish).

• Avoid: alcohol, undercooked meats, high-mercury fish (shark, swordfish), unwashed produce, unpasteurized dairy, and exposures to cats’ litter boxes (toxoplasma) without precautions.

Frequently asked questions (FAQs)

1. Can a child “outgrow” microcephaly?
   The head will keep growing, but the percentile usually stays low. Progress in skills can be significant with therapy.

2. Does every child with microcephaly have intellectual disability?
   No. Severity ranges widely. Some children have mild learning issues; others have more serious challenges.

3. Is microcephaly always genetic?
   No. It can be genetic, infectious, toxic, nutritional, hypoxic, or due to craniosynostosis. Often, more than one factor contributes.

4. How do doctors find the cause?
   By history, exam, brain MRI, and stepwise labs/genetics. Sometimes no single cause is found even after thorough testing.

5. Will my child walk and talk?
   Many do, but timing varies. Early, consistent therapy improves the chances of reaching personal best milestones.

6. Are seizures guaranteed?
   No, but the risk is higher than average. If seizures occur, EEG helps guide treatment.

7. Do helmets or head-shaping devices fix microcephaly?
   No. Helmets are for positional skull flattening, not for brain growth.

8. Is surgery common?
   Only when a specific problem exists (e.g., craniosynostosis, severe feeding issues, drug-resistant epilepsy, orthopedic problems).

9. Are stem cells a cure?
   No approved stem-cell therapy exists for microcephaly. Consider clinical trials cautiously; discuss with specialists.

10. Can diet alone improve head growth?
    Adequate nutrition is essential for overall growth and brain function, but it does not “cure” microcephaly caused by brain developmental issues.

11. What is the long-term outlook?
    It depends on the cause and the presence of other brain differences. Early supports improve participation and quality of life.

12. Can microcephaly be detected before birth?
    Sometimes. Ultrasound in the late second or third trimester may show a small head; fetal MRI can add detail. Results guide counseling, not exact predictions.

13. Should siblings be tested?
    If a genetic cause is found or strongly suspected, genetic counseling can advise on sibling testing and future pregnancy risks.

14. How often should my child be seen?
    Regular visits with pediatrics, neurology, therapy teams, ophthalmology, audiology, nutrition, and dentistry—frequency depends on needs.

15. How can families cope?
    Build a care team, seek parent support groups, use respite care, and make individualized education plans. Celebrate all progress, big or small.
