Microcephalia Vera

Microcephalia vera” means “true microcephaly.” Doctors used this older term for babies who are born with a much smaller head because the brain did not grow normally before birth. Today, we usually say primary (congenital) microcephaly. It is most often genetic and inherited in an autosomal recessive pattern, meaning both parents carry a silent change in the same gene and pass it to the child. In primary microcephaly, head size is small from birth, and the small head reflects a smaller brain, especially the cerebral cortex. This is different from “acquired” or “secondary” microcephaly, where the head becomes small later due to an injury, infection, or other problem after early development. ScienceDirect+2MedlinePlus+2

Microcephalia vera means a baby is born with a head that is much smaller than normal for age and sex. The small head reflects a smaller brain. This happens when the brain does not grow as expected in the womb. It can be isolated or part of a syndrome. Children may have learning problems, seizures, movement trouble, feeding difficulty, speech delay, or vision/hearing issues. There is no single cure. Care is supportive and focuses on function, safety, and family wellbeing. Early therapy helps the brain use its best potential (CDC guidance; AAP clinical reports; peer-reviewed reviews).

Other names

You may also see these names: primary microcephaly, autosomal recessive primary microcephaly (MCPH), hereditary microcephaly, or “true microcephaly.” All point to the same idea: small head at birth due to reduced brain growth during pregnancy, usually because of gene changes that affect how early brain cells divide. ScienceDirect+1

Types

By cause (gene): Many genes can cause primary microcephaly. Two common ones are ASPM and WDR62. Children with changes in these genes are born with a very small head, and some also have differences in how the brain folds. Genetic testing can name the exact subtype. NCBI+1

By timing: Primary microcephaly is present at birth. It starts during pregnancy when brain cells should multiply fast. Acquired microcephaly shows up after birth if the brain is injured or stops growing. The timing helps doctors decide which tests to do. CDC

By associated features: Some children have isolated microcephaly (small head is the main finding). Others have syndromic forms with seizures, movement problems, facial differences, or other organ findings. Brain MRI patterns (for example, simplified gyri or corpus callosum changes) also help define type. Orpha+1

Causes

1. ASPM gene changes. ASPM helps early brain cells divide. When both copies have harmful changes, fewer neurons are made, so the brain and head are smaller at birth. NCBI+1

2. WDR62 gene changes. WDR62 guides cell division and brain folding. Variants can cause microcephaly with cortical malformations on MRI. NCBI+1

3. Other MCPH genes (e.g., CDK5RAP2, CENPJ, STIL, CEP152). These genes organize the centrosome and spindle during cell division. Faults reduce neuron number. BioMed Central

4. Consanguinity (parents related by blood). This raises the chance that both parents carry the same rare recessive change, increasing MCPH risk. World Health Organization

5. DNA repair gene defects. Some rare genes that fix DNA also affect brain growth; when they fail, neurons cannot multiply normally. BioMed Central

6. Mitotic spindle/centrosome pathway problems. Many MCPH genes cluster in this pathway; disturbed spindle function means fewer brain cells form. BioMed Central

7. Neural progenitor migration problems. If early brain cells cannot move to the right place, cortex size and folds are reduced. PubMed

8. Zika virus infection in pregnancy. The virus injures fetal brain cells and stops growth, leading to severe microcephaly. CDC

9. Other congenital infections (e.g., CMV, toxoplasma). These can damage the fetal brain and reduce head growth. CDC

10. Severe malnutrition in pregnancy. Poor nutrients can limit fetal brain growth, though this is less common than genetic causes in “true” MCPH. World Health Organization

11. Exposure to certain toxins. Some chemicals harm developing brain tissue and may cause small head size. CDC

12. Chromosomal abnormalities. Extra or missing chromosomal material can include microcephaly among multiple features. MedlinePlus

13. Placental insufficiency. Poor blood flow to the fetus can stunt brain growth. CDC

14. Radiation exposure in pregnancy. Radiation can kill dividing brain cells and shrink cortical size. CDC

15. Maternal uncontrolled phenylketonuria. High phenylalanine can impair fetal brain development and reduce head size. MedlinePlus

16. Severe maternal illness with high fever. Some infections with prolonged fever are linked to microcephaly in the baby. CDC

17. Metabolic disorders in the fetus. Rare inborn errors of metabolism can lead to poor brain growth and small head. MedlinePlus

18. Vascular events in utero. Strokes or bleeding before birth can reduce brain volume. MedlinePlus

19. Autoimmune attack on the placenta or fetus. Rare maternal antibodies can disturb brain growth. World Health Organization

20. Unknown genetic causes. Many children have primary microcephaly without a named gene yet; more genes are found each year. BioMed Central

Common symptoms or features

1. Small head size from birth. The head circumference is far below average on the newborn chart and stays small over time. MedlinePlus+1

2. Smaller brain volume. MRI often shows a smaller cerebral cortex; this matches the small head size. Orpha

3. Developmental delay. Many children reach milestones later (sitting, walking, talking). Severity varies by gene and child. BioMed Central

4. Learning difficulties. Non-progressive intellectual disability is common in classic MCPH; learning support helps. ScienceDirect

5. Speech delay. Language can be slow to develop because brain networks are smaller or wired differently. BioMed Central

6. Motor delay or clumsiness. Fine motor skills may be affected; physical and occupational therapy can help. BioMed Central

7. Seizures (in some). Not all children have seizures, but some do and need EEG and treatment. Orpha

8. Behavior concerns. Some children show attention or hyperactivity problems and benefit from structured support. MedlinePlus

9. Feeding issues in infancy. Weak suck, poor coordination, or reflux may occur in severe cases. MedlinePlus

10. Hearing or vision problems. A few children have hearing loss or vision issues; early screening helps. Orpha

11. Abnormal brain folds on MRI (some genes). WDR62 and others can show simplified gyri or other malformations. PubMed

12. Small stature in some children. Some have lower growth percentiles beyond head size. Orpha

13. Normal facial appearance or mild differences. Many look typical; some have subtle facial traits linked to the gene. BioMed Central

14. Non-progressive course. The condition usually does not worsen over time; children keep learning and gaining skills. ScienceDirect

15. Family history suggestive of recessive inheritance. Multiple affected siblings, healthy parents, or consanguinity can be clues. World Health Organization

Diagnostic tests

A) Physical examination (at the bedside)

1. Accurate head-circumference (OFC) measurement. The tape goes around the biggest part of the head. Doctors compare the number with age- and sex-based charts to see how far below average it is. Repeated measures over months show the growth curve. MedlinePlus

2. Full body and neurologic exam. The doctor checks tone, reflexes, strength, coordination, and looks for signs that point to a syndrome or brain injury. This helps decide which tests to do next. American Physical Therapy Association

3. Developmental assessment. Simple tools or formal tests check movement, speech, problem-solving, and social skills. Results guide therapy plans. American Physical Therapy Association

4. Dysmorphology review. A clinical geneticist examines facial features, hands, skin, and other clues that suggest a specific genetic condition. Orpha

5. Family and pregnancy history. Doctors ask about relatives with small head size, consanguinity, infections, fevers, medications, and exposures in pregnancy. This history can point to genetic vs acquired causes. World Health Organization

B) Manual/bedside tests (simple office-based procedures)

6. Vision screening. Age-appropriate checks (tracking, fixation, chart tests) look for vision problems linked to brain development. Early detection helps learning. MedlinePlus

7. Hearing screening. Bedside hearing checks (otoacoustic emissions or simple responses) flag children who need full audiology testing. Hearing support improves speech outcomes. CDC

8. Growth measurements. Length/height and weight plotted with head size show whether the small head is isolated or part of a broader growth issue. MedlinePlus

9. Neurologic observation over time. Follow-up visits watch for seizures, regression, or new signs. A stable pattern supports primary microcephaly. ScienceDirect

10. Developmental screening tools. Tools like parent questionnaires or play-based tasks give a quick picture and trigger early therapy referrals. American Physical Therapy Association

C) Laboratory and pathological tests

11. Infection testing (as needed). If pregnancy infections are possible, doctors test for CMV, toxoplasma, or Zika exposure. Positive results suggest a secondary cause. CDC

12. Metabolic screening. Blood and urine tests check for rare metabolic conditions that can include microcephaly; abnormal results change treatment plans. MedlinePlus

13. Chromosomal microarray. This lab test looks for extra or missing DNA segments. It is often a first-line genetic test when the cause is unclear. American Physical Therapy Association

14. Single-gene or multigene panels for MCPH. If the picture suggests primary microcephaly, panels that include ASPM, WDR62, and related genes can find the exact cause and confirm recessive inheritance. NCBI+1

15. Exome or genome sequencing. If panels are negative, exome/genome testing can discover rare or new genes. A named diagnosis helps with prognosis and family planning. BioMed Central

D) Electrodiagnostic tests

16. EEG (electroencephalogram). If a child has spells or suspected seizures, EEG records brain waves and helps diagnose the seizure type so doctors can choose medicines. American Physical Therapy Association

17. Evoked potentials (as needed). Visual or auditory evoked tests check how the brain responds to sights and sounds; they help when vision or hearing pathways are in question. American Physical Therapy Association

E) Imaging tests

18. Brain MRI. MRI shows brain size and structure in detail. In primary microcephaly, MRI may show a small cortex and sometimes simplified folds. It can also reveal other changes that point to a specific gene. PubMed+1

19. Cranial ultrasound (infancy). In very young babies, ultrasound through the soft spot is a quick way to screen for major brain differences before MRI. American Physical Therapy Association

20. Head CT (selected cases). CT is faster but uses radiation, so it is reserved for urgent needs (like bleeding) or when MRI is not possible. American Physical Therapy Association

Non-Pharmacological Treatments (Therapies & Others)

1. Early Intervention (EI) Care Coordination
   Description: EI links the family with therapists and services from birth to 3–5 years. A coordinator helps set goals and tracks progress. Visits can be at home, clinic, or daycare.

Dietary Molecular Supplements

1. Docosahexaenoic Acid (DHA, Omega-3)
   Dose: Often 10–20 mg/kg/day DHA (within pediatric nutrition limits). Function/Mechanism: DHA is a key neuron membrane lipid; supports synapse fluidity and visual pathway function; may aid attention in some children. Evidence is mixed; use as part of balanced diet with fish where safe (nutrition reviews; WHO/FAO fatty acid guidance).

2. Iron (if deficient)
   Dose: Treatment typically ~3–6 mg/kg/day elemental iron under supervision. Function/Mechanism: Restores hemoglobin and brain iron-dependent enzymes for myelination and neurotransmitters; screens first to avoid overload (AAP iron statements; WHO anemia guidance).

3. Zinc
   Dose: Age-appropriate RDA; supplements when low intake/low serum. Function/Mechanism: Cofactor for hundreds of enzymes; supports growth, appetite, and immune function; best with food to avoid nausea (nutrition reviews; WHO zinc guidance).

4. Vitamin D
   Dose: Age-appropriate RDA or per level; avoid excess. Function/Mechanism: Bone health, muscle function, and immune modulation; low levels common in children with limited sun or mobility (AAP vitamin D statements; endocrine guidelines).

5. Folate (Folic Acid)
   Dose: RDA for age; higher only if deficiency. Function/Mechanism: One-carbon metabolism for DNA synthesis; supports growth; in pregnancy prevents neural tube defects (maternal prevention) (WHO; ACOG).

6. Vitamin B12 (if low)
   Dose: Age-appropriate, oral or IM if severe deficiency. Function/Mechanism: Myelin and DNA synthesis; deficiency causes anemia and neuro signs; check levels before treatment (AAP; hematology texts).

7. Iodine

Immunity-Booster / Regenerative / Stem Cell Drugs

Key point: There are no FDA-approved regenerative or stem cell drugs for microcephalia vera. Unregulated stem cell clinics can be dangerous and costly. Below are six items to clarify evidence and safer alternatives (FDA consumer alerts; AAP policy).

1. Routine Vaccines (not “drugs” but essential)
   Use: Follow national schedule. Dose: Per schedule. Function: Prevent infections that can worsen outcomes and hospital stays. Mechanism: Adaptive immunity to target pathogens (CDC immunization schedule; WHO).

2. Palivizumab (RSV prophylaxis) for eligible infants
   Dose: Monthly seasonal dosing per label for high-risk infants. Function: Reduce serious RSV disease. Mechanism: Monoclonal antibody binds RSV F protein. Note: Only for specific high-risk criteria (FDA label; AAP RSV guidance).

3. Mecasermin (rhIGF-1) – NOT for microcephaly; for severe primary IGF-1 deficiency
   Dose: Label-directed. Function/Mechanism: Replaces IGF-1; not indicated for microcephaly; risk of hypoglycemia (FDA label; endocrine guidance).

4. Erythropoietin (neuroprotection) – Investigational
   Use: Trials in neonatal brain injury; not standard for microcephaly. Mechanism: Anti-apoptotic/angiogenic signals; evidence not sufficient for routine use (neonatal neurology trials).

5. Intravenous Immunoglobulin (IVIG)
   Use: Only for defined immune disorders, not for microcephaly itself. Mechanism: Passive immunity; risks include thrombosis and aseptic meningitis (FDA labeling; immunology guidelines).

6. Cell-based Therapies (Stem Cells)
   Status: No FDA-approved products for microcephaly; clinic offerings outside trials are unsafe/unproven. Mechanism claim: “Regeneration” is not proven; risks include infection and tumor formation. Prefer registered clinical trials only (FDA advisories; NIH ClinicalTrials.gov overview).

Surgeries

1. Gastrostomy Tube (G-tube)
   Procedure: Small surgical opening into the stomach with a tube/button. Why: Long-term poor oral intake, aspiration risk, or severe oromotor dysfunction to ensure safe nutrition and medication delivery (pediatric surgery texts; ESPGHAN).

2. Intrathecal Baclofen Pump Placement
   Procedure: Programmable pump under the skin with a catheter to CSF. Why: Severe generalized spasticity not controlled by oral drugs, to improve comfort and care (rehab guidelines; FDA device/med labeling).

3. Selective Dorsal Rhizotomy (SDR) – Selected cases
   Procedure: Neurosurgeon cuts selected sensory rootlets to reduce spasticity. Why: Carefully chosen children with severe spasticity to improve mobility/care; requires intensive rehab (neurosurgery guidelines; CP literature).

4. Strabismus Surgery
   Procedure: Eye muscle adjustment under anesthesia. Why: Improve ocular alignment to aid vision and reduce diplopia/suppression (ophthalmology guidelines).

5. Cochlear Implantation (if severe sensorineural hearing loss)
   Procedure: Internal electrode array plus external processor. Why: Provide sound access to boost language development when hearing aids are not enough (ENT/pediatric audiology guidelines).

---

Preventions

1. Pre-pregnancy Counseling & Folic Acid – Daily folic acid lowers neural tube defects and supports early brain formation (WHO; ACOG).

2. Vaccination (Rubella, Varicella, Influenza, COVID-19 as recommended) – Prevent maternal infections linked with fetal harm (CDC; WHO).

3. Avoid Teratogens – No alcohol or illicit drugs; review prescription drugs (e.g., avoid valproate in pregnancy if possible) (FDA; ACOG).

4. Prevent Zika and Other Arboviruses – Mosquito control, travel advisories, repellents, and safe sex if partner exposure (CDC; WHO).

5. Treat Maternal Conditions – Control diabetes, PKU, thyroid disease, malnutrition, and infections (ACOG; WHO).

6. Iodized Salt and Balanced Diet – Adequate iodine and micronutrients for fetal brain (WHO/UNICEF).

7. Avoid Radiation/Toxins – Limit non-essential radiation and workplace solvents with obstetric guidance (ACOG).

8. Genetic Counseling – Especially with family history, consanguinity, or prior affected child (genetics guidelines).

9. Prenatal Care & Ultrasound – Early, regular visits detect problems and guide management (WHO; ACOG).

10. Safe Birth and Newborn Screening – Skilled delivery, newborn checks, and early referral to EI (AAP; WHO).

When to See Doctors

See a doctor now if seizures last >5 minutes, repeated vomiting, breathing trouble, cyanosis, unresponsiveness, or head injury (epilepsy first-aid; AAP). See your clinician soon if feeding is unsafe or very slow, weight is not increasing, new stiffness or falls, worsening sleep and behavior, frequent choking, or suspected vision/hearing loss. Keep regular follow-ups with pediatrics, neurology, rehab, nutrition, ophthalmology, audiology, dentistry, and social work. Early help changes outcomes (AAP; neurology/rehab guidance).

---

What to Eat and What to Avoid

1. Eat: Energy-dense foods (nut butters, avocado, yogurt) if growth is slow—easier calories in small volumes (ESPGHAN; AAP).

2. Eat: Protein at each meal (eggs, dairy, legumes, lean meats) to support muscle and healing (nutrition guidelines).

3. Eat: Fruits/vegetables in textures the child can manage; use purees if chewing is weak (ESPGHAN).

4. Eat: Whole grains for fiber to prevent constipation (pediatric GI guidance).

5. Eat: Adequate fluids; consider water-plus-electrolyte options if constipation or hot weather (AAP).

6. Avoid: Hard, round, or sticky foods that raise choking risk (whole nuts, hard candies) unless fully modified (AAP).

7. Avoid: Excess juice/sugary drinks that displace real nutrients (AAP).

8. Avoid: Ultra-processed snack foods as main calories; they add salt/sugar but little nutrition (nutrition reviews).

9. Avoid: Inadequate micronutrients—ask for dietitian review for iron, vitamin D, iodine, B12, and zinc (AAP/WHO).

10. Avoid: Unproven “brain boosters” or mega-supplements sold online; they can harm and waste money (FDA consumer updates).
