From the Guidelines
The prognosis of periventricular calcifications in neonates is generally poor, with a significant risk of neurodevelopmental challenges, including cerebral palsy, intellectual disability, seizures, visual impairments, and hearing loss, particularly in cases of congenital toxoplasmosis, as reported in a study published in Pediatrics in 2017 1.
Causes and Outcomes
The underlying cause of periventricular calcifications plays a crucial role in determining the prognosis. Congenital toxoplasmosis is a significant cause of periventricular calcifications, and the outcomes can be severe. According to a study published in Pediatrics in 2017, infants with congenital toxoplasmosis and severe findings at birth, including periventricular calcifications, have a lower likelihood of normal motor-neurologic outcomes, normal cognitive outcome, and normal auditory outcome compared to those with no or mild findings at birth 1.
Treatment and Management
Early treatment and management of periventricular calcifications are critical in improving outcomes. For congenital toxoplasmosis, postnatal treatment has been shown to improve neurologic outcomes, including the resolution of seizures and tone and motor abnormalities 1. However, the presence of additional brain abnormalities, such as hydrocephalus, ventriculomegaly, or white matter damage, can further worsen the prognosis.
Key Considerations
- The extent and location of calcifications directly correlate with outcome severity, with more extensive calcifications indicating poorer prognosis.
- Early antiviral treatment and comprehensive follow-up, including regular neurological assessments, developmental screening, and hearing and vision evaluations, are essential in managing periventricular calcifications.
- Other causes of periventricular calcifications, such as congenital cytomegalovirus infection, rubella, herpes simplex virus, and genetic disorders, each have distinct treatment approaches and prognostic implications.
- The presence of additional brain abnormalities, such as ventriculomegaly, microcephaly, or white matter damage, further worsens the prognosis.
Recommendations
- All affected infants require comprehensive follow-up and early intervention services, including physical, occupational, and speech therapy, to address developmental delays and improve outcomes.
- Healthcare providers should be aware of the potential causes and outcomes of periventricular calcifications and provide timely and appropriate management to improve prognosis.
From the Research
Prognosis of Periventricular Calcifications in Newborns
The prognosis of periventricular calcifications in newborns is associated with various neurodevelopmental outcomes. Some key points to consider include:
- Periventricular calcifications can be a sign of underlying brain injury, such as periventricular leukomalacia (PVL) or intraventricular hemorrhage (IVH) 2, 3.
- Infants with PVL or IVH are at a higher risk of developing cerebral palsy, cognitive delay, and other neurodevelopmental impairments 4, 5, 2, 3.
- The severity of PVL or IVH can impact the prognosis, with more severe cases associated with poorer outcomes 5, 2, 3.
- Early diagnosis and intervention are crucial in identifying and addressing potential neurodevelopmental delays or impairments 4, 3.
Neurodevelopmental Outcomes
Some specific neurodevelopmental outcomes associated with periventricular calcifications in newborns include:
- Cerebral palsy: Infants with PVL or IVH are at a higher risk of developing cerebral palsy, with symmetrical diplegic cerebral palsy being the most common type associated with PVL 5.
- Cognitive delay: Infants with PVL or IVH may experience cognitive delays or impairments, with the severity of the brain injury impacting the degree of delay 4, 2.
- Visual and hearing impairments: Infants with PVL or IVH may also be at risk of visual and hearing impairments, particularly if the brain injury is severe 2.
Risk Factors
Some risk factors that can impact the prognosis of periventricular calcifications in newborns include:
- Gestational age: Infants born at earlier gestational ages are at a higher risk of developing PVL or IVH 4, 3.
- Birth weight: Infants with lower birth weights are also at a higher risk of developing PVL or IVH 4, 3.
- Presence of other brain injuries: Infants with multiple brain injuries, such as PVL and IVH, may be at a higher risk of poor neurodevelopmental outcomes 2, 3.
