Introduction to Intracranial Hemorrhage in Newborns
When a baby is diagnosed with intracranial hemorrhage—bleeding inside the skull—parents face an overwhelming situation. This serious condition can occur during pregnancy, labor, delivery, or shortly after birth, and its effects can range from temporary to permanently life-altering. Understanding what intracranial hemorrhage is, what causes it, and what options are available is essential for families navigating this medical crisis.
At Birth Injury Law NY, we work with families affected by birth injuries, providing free educational information and connecting them with qualified legal advocates. This comprehensive guide explains the types of intracranial hemorrhage in newborns, the causes (including birth trauma from medical errors), diagnostic approaches, treatment options, and long-term outcomes. Our goal is to help you understand this condition so you can advocate effectively for your baby’s care and, if appropriate, pursue legal remedies for preventable injuries.
Whether your child experienced intracranial hemorrhage due to prematurity, delivery complications, or potentially preventable medical errors, this guide provides the medical information and legal context you need.
What is Intracranial Hemorrhage?
Intracranial hemorrhage (ICH) is bleeding that occurs inside the skull when a blood vessel in or near the brain ruptures or leaks. The blood accumulates in the brain tissue or in the spaces surrounding the brain, creating pressure that can damage brain cells and interfere with normal brain function. In newborns, this is a particularly serious condition because their brains are still developing and more vulnerable to injury.
According to MedlinePlus, the National Library of Medicine’s patient information resource, intracranial hemorrhage in newborns is a medical emergency that requires immediate diagnosis and treatment. The severity and long-term impact depend on several factors including the location and extent of the bleeding, the baby’s gestational age at birth, and how quickly medical professionals intervene.
The incidence of symptomatic intracranial hemorrhage varies significantly by delivery method: approximately 1 in 2,000 spontaneous vaginal births, 1 in 850 vacuum-assisted deliveries, and 1 in 650 forceps-assisted deliveries result in clinically significant intracranial hemorrhage. These statistics highlight the substantial risk associated with assisted delivery methods.
Key Point: Intracranial hemorrhage is a serious but sometimes preventable condition. The location, type, and extent of bleeding determine immediate and long-term outcomes. Early diagnosis and appropriate medical management are critical.
Types of Intracranial Hemorrhage in Newborns
Intracranial hemorrhage can occur in different locations within and around the brain. Understanding these different types is essential because each presents different risks, causes, and outcomes. Healthcare providers classify intracranial hemorrhage based on where the bleeding occurs relative to the protective layers surrounding the brain.
| Type | Location | Most Common In | Typical Cause | Clinical Significance |
|---|---|---|---|---|
| Subdural Hemorrhage | Between dura and brain surface | Term infants | Birth trauma (forceps/vacuum) | Usually serious; may be asymptomatic |
| Subarachnoid Hemorrhage | Between arachnoid and pia mater | Premature infants | Vascular rupture; prematurity | Common but usually benign |
| Intraventricular Hemorrhage | In brain ventricles (fluid-filled areas) | Premature infants | Germinal matrix rupture | Common and usually serious in preterm |
| Epidural Hemorrhage | Between skull and dura mater | Both; more severe in term | Head trauma; vascular injury | Highly serious; requires urgent intervention |
| Parenchymal Hemorrhage | Within brain tissue itself | Both; more common in term | Birth trauma; coagulopathy | Serious; high risk of long-term disability |
Subdural Hemorrhage (SDH)
Subdural hemorrhage occurs when blood vessels between the outermost brain membrane (dura mater) and the brain surface rupture. This is the most common type of intracranial hemorrhage in full-term newborns. According to research from the National Center for Biotechnology Information, subdural hemorrhage is more frequent in term infants than premature infants and is generally clinically serious when it occurs.
The primary cause of subdural hemorrhage in newborns is birth trauma, particularly from improper use of forceps or vacuum extraction during delivery. The mechanical pressure from delivery instruments or from excessive traction during labor can rupture delicate blood vessels in the subdural space. Importantly, many cases of subdural hemorrhage following normal delivery or instrumental delivery are initially asymptomatic—the baby may show no symptoms—yet the bleeding can still have serious consequences.
Unlike some other hemorrhages, many subdural hemorrhages resolve spontaneously within approximately 4 weeks without requiring surgical intervention. However, close monitoring is essential to ensure proper resolution and to watch for any signs of complications.
Subarachnoid Hemorrhage (SAH)
Subarachnoid hemorrhage is bleeding in the space between two protective membranes: the arachnoid layer and the pia mater. This is actually the most common type of intracranial hemorrhage overall, but it is more frequently seen in premature infants than full-term newborns.
Subarachnoid hemorrhage has an important distinction: while it is common, it is usually clinically benign, meaning most babies with uncomplicated SAH have better long-term outcomes compared to other types of intracranial bleeding. However, the underlying causes can vary, and some cases may be more serious depending on the extent and location of the bleeding.
Intraventricular Hemorrhage (IVH)
Intraventricular hemorrhage occurs when bleeding happens into the ventricles—the fluid-filled spaces deep within the brain. According to MedlinePlus, IVH is almost exclusively a condition affecting premature infants, particularly those born more than 10 weeks early. The smaller and more premature an infant is, the higher the risk.
IVH is caused by rupture of fragile blood vessels in an area called the germinal matrix—a region in the developing brains of premature infants that is particularly vulnerable. IVH contrasts sharply with subarachnoid hemorrhage: while IVH is less common overall, it is usually serious when it occurs, with significant risk of long-term complications.
Medical professionals classify IVH into four grades based on severity:
- Grade I: Bleeding limited to germinal matrix
- Grade II: Bleeding into ventricles without dilation
- Grade III: Bleeding into ventricles with ventricular dilation
- Grade IV: Bleeding into surrounding brain tissue (parenchymal hemorrhage)
Higher grades indicate more serious bleeding and higher risk of neurodevelopmental complications.
Other Types of Intracranial Hemorrhage
Additional types include epidural hemorrhage (between the skull and dura mater) and parenchymal hemorrhage (bleeding within brain tissue itself). While less common than the three main types, these can be particularly serious when they occur. Epidural hemorrhage, in particular, is a medical emergency because the accumulated blood can create dangerous pressure within the skull.
Causes and Risk Factors for Intracranial Hemorrhage
Understanding what causes intracranial hemorrhage is crucial for prevention and for determining whether medical care met appropriate standards. The causes differ somewhat between premature and full-term infants, and some causes are preventable through proper medical care.
Birth Trauma and Instrumental Delivery
For full-term newborns, birth trauma is a major cause of intracranial hemorrhage. The use of delivery instruments—particularly forceps and vacuum extractors—carries substantial risk. When used improperly or in inappropriate circumstances, these instruments can create excessive pressure on the baby’s head, injuring delicate blood vessels and causing bleeding inside the skull.
The key statistics demonstrate this risk clearly: research indicates that intracranial hemorrhage occurs in approximately 1 in 650 forceps-assisted deliveries and 1 in 850 vacuum-assisted deliveries—rates significantly higher than the 1 in 2,000 rate for spontaneous vaginal deliveries.
Medical malpractice in delivery can include:
- Improper application or positioning of vacuum cups or forceps
- Excessive traction or force during extraction
- Prolonged use of delivery instruments
- Failure to recognize that instrumental delivery should not be attempted or should be abandoned
- Using both vacuum and forceps together
- Applying instruments to an incompletely dilated cervix or incorrectly presented baby
Any of these errors can lead to serious intracranial hemorrhage in the newborn.
Prematurity and Immature Blood Vessels
For premature infants, the primary cause of intracranial hemorrhage is prematurity itself. The brains of premature infants have immature blood vessels that are more fragile and prone to rupture. In addition, premature infants have an area in their developing brains called the germinal matrix—a region rich with blood vessels but lacking structural support. This area is particularly vulnerable to hemorrhage.
The risk of IVH correlates strongly with degree of prematurity: infants born more than 10 weeks early have substantially higher risk than those born just a few weeks early.
Medical Conditions and Complications
Various medical conditions can increase the risk of intracranial hemorrhage:
- Respiratory distress: Difficulty breathing increases intracranial pressure
- Hypoxia: Low oxygen levels stress fragile blood vessels
- Infection: Maternal or neonatal infections increase bleeding risk
- Coagulopathy: Blood clotting disorders prevent normal hemostasis
- Thrombocytopenia: Low platelet count reduces clotting ability
- Vitamin K deficiency: Impairs production of clotting factors
- Hemorrhagic disease of the newborn: Rare but serious clotting disorder
- Perinatal asphyxia: Lack of oxygen during birth damages vessels
Other Risk Factors
Additional risk factors include maternal infections (particularly group B strep), maternal anticonvulsant use, fetal thrombocytopenia, vascular malformations, and genetic bleeding disorders. In some cases, intracranial hemorrhage results from stroke-like events in newborns, which can stem from thrombosis or other vascular complications.
Symptoms and Signs of Intracranial Hemorrhage
The symptoms of intracranial hemorrhage can vary widely depending on the type, location, and severity of bleeding. Some babies show obvious symptoms while others, particularly with certain types of subdural hemorrhage, may be initially asymptomatic.
Acute symptoms may include:
- Seizures (the most common presenting symptom, occurring in approximately 71.7% of cases in one study)
- Unusual crying or high-pitched cry
- Lethargy or decreased responsiveness
- Poor feeding or feeding difficulties
- Vomiting
- Breathing problems
- Bulging fontanelle (soft spot on head)
- Jaundice (yellowing of skin)
- Muscle rigidity or abnormal muscle tone
Long-term manifestations may develop gradually and include:
- Developmental delays
- Cerebral palsy
- Intellectual disability
- Vision or hearing problems
- Learning disabilities
- Behavioral or emotional difficulties
- Seizure disorders
It’s important to note that absence of symptoms does not mean absence of serious bleeding. Some newborns with intracranial hemorrhage appear completely normal initially, yet imaging studies reveal significant bleeding that may cause problems later.
Diagnosis and Evaluation of Intracranial Hemorrhage
Prompt diagnosis of intracranial hemorrhage is essential for optimal outcomes. Modern imaging technology allows healthcare providers to identify and assess bleeding quickly.
Neuroimaging Methods
Cranial Ultrasound: This is typically the first imaging study performed on newborns suspected of having intracranial hemorrhage. Ultrasound is non-invasive, requires no radiation, and can be performed at the bedside. It is particularly useful for detecting intraventricular hemorrhage and can be repeated serially to monitor bleeding progression.
CT Scan (Computed Tomography): CT scans provide detailed images of the brain and are excellent at identifying different types of intracranial hemorrhage. However, CT exposes the baby to radiation, so it is typically used when ultrasound is inconclusive or when more detailed imaging is needed.
MRI (Magnetic Resonance Imaging): According to Texas Children’s Hospital, MRI provides excellent detailed imaging of the brain and is particularly useful for assessing the extent of bleeding and for long-term follow-up. MRI does not use radiation and can detect subtle injuries, but it takes longer and may require sedation.
Clinical Assessment
Healthcare providers also perform careful clinical examination, checking muscle tone, reflexes, responses to stimulation, and any signs of increased intracranial pressure. They assess fontanelle firmness, head circumference, and neurological function.
Severity Grading
For intraventricular hemorrhage specifically, the four-grade classification system helps guide prognosis and treatment planning. Lower grades (I-II) generally have better outcomes than higher grades (III-IV), though individual outcomes vary considerably.
Treatment and Management of Intracranial Hemorrhage
Treatment of intracranial hemorrhage focuses on stabilizing the baby, preventing further complications, and supporting brain function during recovery. Specific treatments depend on the type and severity of hemorrhage.
Acute Management
Stabilization: The first priority is ensuring adequate breathing, oxygenation, and circulation. Babies with intracranial hemorrhage may require supplemental oxygen, mechanical ventilation, or other intensive support.
Monitoring: Close continuous monitoring of vital signs, neurological status, and intracranial pressure is essential. Frequent neuroimaging helps track whether bleeding is stable, resolving, or progressing.
Seizure Management: Since seizures are the most common presenting symptom, medications to control seizures (anticonvulsants) are often necessary. Management focuses on preventing complications and supporting the baby through the acute phase.
Supportive Care
Hydration and Nutrition: Proper feeding and fluid management support recovery. Some babies may require intravenous nutrition initially.
Temperature Regulation: Hypothermia (cooling) therapy has shown promise in some cases of perinatal asphyxia-related hemorrhage.
Correction of Coagulopathy: If bleeding disorders are present, blood products or vitamin K may be administered.
Long-Term Therapy and Follow-Up
Following the acute phase, babies with intracranial hemorrhage typically require ongoing developmental monitoring and support. Physical therapy, occupational therapy, and speech therapy help optimize developmental outcomes. Early intervention services provide critical support during the first years of life when brain plasticity is greatest.
Regular follow-up appointments with pediatric neurologists and developmental pediatricians help track progress and adjust therapy as needed.
Long-Term Outcomes and Prognosis for Intracranial Hemorrhage
The long-term outcomes of intracranial hemorrhage in newborns vary considerably. Several factors influence whether a child will have normal development or experience lasting complications.
Factors Affecting Outcomes
Type and Severity of Hemorrhage: Subdural and epidural hemorrhages can be serious but sometimes resolve without permanent damage. Intraventricular hemorrhage, particularly higher grades, carries higher risk of long-term complications. Subarachnoid hemorrhage generally has the most favorable prognosis.
Location of Bleeding: The specific location of bleeding within the brain significantly affects which functions are impacted and to what degree.
Extent of Bleeding: Larger volumes of bleeding cause more damage and typically result in more severe outcomes.
Gestational Age: Premature infants face higher risk of long-term complications from any given bleeding event, as their brains are still developing critical connections.
Associated Conditions: Babies with additional complications—such as perinatal asphyxia, infection, or coagulation disorders—face worse outcomes than those with isolated intracranial hemorrhage.
Outcome Statistics: Research indicates that in term infants with intracranial hemorrhage, approximately 44.4% experience poor outcomes, with perinatal asphyxia as the most statistically significant contributing cause. However, other studies report that normal neurodevelopmental outcomes occur in as many as 83.8% of surviving patients, highlighting the wide variation in individual cases.
Possible Long-Term Complications
Children who survive intracranial hemorrhage may experience:
- Cerebral Palsy: The most common serious long-term complication, occurring when bleeding damages motor control areas
- Developmental Delays: Slower achievement of motor, cognitive, or social milestones
- Intellectual Disability: Ranging from mild to severe, depending on severity and location of bleeding
- Seizure Disorders: Some children develop epilepsy requiring long-term medication
- Vision Problems: Including cortical visual impairment, refractive errors, or strabismus
- Hearing Loss: May range from mild to profound
- Learning Disabilities: Specific difficulties with reading, math, or other academic skills
- Behavioral Issues: Including ADHD, autism spectrum features, or emotional regulation difficulties
- Hydrocephalus: Excessive cerebrospinal fluid buildup requiring shunt placement
Positive Prognostic Factors
Early diagnosis and aggressive treatment improve outcomes. Access to early intervention services, family support, and specialized therapy can maximize developmental potential. Many children with mild to moderate intracranial hemorrhage achieve normal or near-normal development with appropriate support. The neonatal period represents a critical window for brain development, and intensive therapeutic support during this time can significantly influence long-term capabilities.
Intracranial Hemorrhage and Medical Negligence in New York
When intracranial hemorrhage occurs as a result of medical errors or inadequate obstetrical care, families may have legal options. In New York, medical professionals are held to high standards of care, and failures that result in preventable birth injuries can constitute medical malpractice.
Situations that may involve medical negligence include improper use of delivery instruments, failure to recognize maternal or fetal complications that should have prompted a cesarean section, failure to properly monitor mother and baby during labor, and failure to identify risk factors that would contraindicate instrumental delivery.
If your child has intracranial hemorrhage and you believe medical errors contributed to the injury, it is important to consult with a qualified birth injury attorney. Many families who pursue claims recover substantial compensation to support their child’s ongoing medical and developmental needs.

Frequently Asked Questions About Intracranial Hemorrhage
What is the difference between the types of intracranial hemorrhage in newborns?
The main types differ in location: subdural hemorrhage is between the dura and brain surface (most common in term infants), subarachnoid is between protective membranes (common but usually benign), intraventricular is in brain ventricles (serious in premature infants), and epidural or parenchymal hemorrhage involve other locations. Each has different typical causes and different prognosis. Term infants more commonly develop subdural and parenchymal hemorrhages from birth trauma, while premature infants develop intraventricular hemorrhage from immature blood vessels.
What causes intracranial hemorrhage in newborns?
In term infants, birth trauma—especially improper use of forceps or vacuum extraction—is a major cause. In premature infants, immature fragile blood vessels and the vulnerable germinal matrix cause hemorrhage. Other causes include perinatal asphyxia, infection, coagulation disorders, vascular malformations, and genetic conditions. Risk significantly increases with instrumental delivery: 1 in 650 forceps-assisted deliveries and 1 in 850 vacuum-assisted deliveries result in intracranial hemorrhage, compared to 1 in 2,000 spontaneous vaginal deliveries.
What are the symptoms of intracranial hemorrhage in a newborn?
Acute symptoms may include seizures (most common—71.7% of cases), unusual or high-pitched crying, poor feeding, lethargy, vomiting, breathing difficulties, or a bulging soft spot on the head. However, some newborns with significant bleeding are initially asymptomatic. Long-term symptoms may include developmental delays, cerebral palsy, vision or hearing problems, or intellectual disability. The absence of immediate symptoms does not indicate absence of serious bleeding.
How is intracranial hemorrhage diagnosed?
Diagnosis typically begins with cranial ultrasound, which is non-invasive, can be done at bedside, and is excellent for detecting intraventricular hemorrhage. CT scans provide detailed images but involve radiation exposure. MRI provides excellent detail without radiation and is used for comprehensive assessment or follow-up. Clinical examination assessing neurological function, muscle tone, and fontanelle firmness also contributes to diagnosis. Imaging helps determine type, location, severity, and grade of hemorrhage.
What is the treatment for intracranial hemorrhage in newborns?
Treatment focuses on stabilization (ensuring adequate oxygen and circulation), continuous monitoring, seizure management with medications if needed, and supportive care including proper nutrition and fluid management. Some cases require surgical intervention to relieve dangerous pressure. Long-term management includes developmental monitoring, physical and occupational therapy, and early intervention services. Specific treatment depends on hemorrhage type, severity, and underlying cause.
What are the long-term outcomes for babies with intracranial hemorrhage?
Outcomes vary widely and depend on type, location, severity, gestational age, and associated conditions. Some babies recover completely with no lasting effects, while others experience permanent disabilities including cerebral palsy, developmental delays, intellectual disability, seizure disorders, vision/hearing loss, or learning disabilities. Research shows poor outcomes in 44.4% of term infants with ICH, though other studies report normal outcomes in 83.8% of survivors—the wide variation reflects individual case differences. Early intervention significantly improves long-term capabilities.
Is intracranial hemorrhage preventable?
Many cases of intracranial hemorrhage can be prevented through appropriate obstetrical care. Avoiding unnecessary or improperly performed instrumental deliveries, recognizing when cesarean section should be performed instead, properly monitoring mother and baby during labor, and managing maternal complications all reduce risk. Some hemorrhages related to prematurity or genetic conditions cannot be prevented, but early diagnosis and aggressive treatment minimize long-term damage.
Can a baby with intracranial hemorrhage be compensated for a birth injury?
Yes, if medical errors or inadequate care caused or contributed to the intracranial hemorrhage. In New York, families can pursue medical malpractice claims for damages including medical costs, therapy expenses, special education, and pain and suffering. Many attorneys work on contingency—families pay nothing unless they win. Free case evaluations are available. Whether a specific case qualifies depends on evidence that the baby’s care fell below the standard of care required of medical professionals.
How long does recovery from intracranial hemorrhage take?
Recovery timelines vary dramatically based on hemorrhage severity, type, location, and individual factors. Some hemorrhages resolve spontaneously within weeks (particularly some subdural hemorrhages). Others require months or years of intensive therapy with ongoing improvements possible throughout childhood. The neonatal period is critical for brain development, and aggressive early intervention during this window significantly influences long-term outcomes. Many children continue to show developmental improvements for years with appropriate therapy and support.
What role does prematurity play in intracranial hemorrhage?
Prematurity significantly increases risk of intraventricular hemorrhage because premature infants have immature, fragile blood vessels and a vulnerable area of the brain called the germinal matrix. The more premature an infant, the higher the risk. Premature infants represent the primary population for IVH. In contrast, subdural hemorrhage (which occurs from birth trauma) is more common in term infants. Premature infants with any intracranial hemorrhage face higher risk of long-term complications because their brains are still developing critical neural connections.
What should I do if my newborn has been diagnosed with intracranial hemorrhage?
First, ensure your baby receives comprehensive medical evaluation and treatment from specialized pediatric neurologists and other experts. Ask your medical team detailed questions about the type, location, severity, and expected prognosis specific to your baby’s condition. Follow all recommendations for imaging, monitoring, and specialist follow-up. Enroll in early intervention services as soon as possible.
