Perinatal stroke

Perinatal Stroke

Perinatal stroke (pronunciation: /ˌpɛrɪˈneɪtəl stroʊk/) is a type of stroke that occurs in the period shortly before, during, or after birth, specifically from the 20th week of gestation to the 28th day post birth.

Etymology

The term "perinatal" is derived from the Greek words "peri-", meaning around or about, and "natal", meaning birth. The term "stroke" comes from the Old English "strac", meaning a blow or strike, which reflects the sudden onset of symptoms.

Definition

A perinatal stroke is a cerebrovascular event that leads to an area of focal necrosis of the brain tissue occurring between the 20th week of fetal life through the 28th day of neonatal life. It is a common cause of neurological impairment in children.

Types

There are several types of perinatal stroke, including:

Neonatal Arterial Ischemic Stroke (NAIS): This is the most common form of perinatal stroke. It occurs when blood flow to an infant's brain is interrupted by a clot or other blockage in an artery.

Neonatal Hemorrhagic Stroke (NHS): This type of stroke occurs when a blood vessel in the brain ruptures, causing bleeding in the surrounding tissue.

Periventricular Venous Infarction (PVI): This type of stroke occurs when there is damage to the veins that drain blood from the brain.

Symptoms

Symptoms of a perinatal stroke can vary widely, but may include seizures, difficulty feeding, lethargy, and developmental delays.

Treatment

Treatment for perinatal stroke often involves managing the symptoms and complications that can arise from the stroke. This may include medications to control seizures, physical therapy to manage motor impairments, and speech therapy to address language and communication issues.
