What are neonatal seizures?

neonatal seizures are seizures that occur in the child during the first 28 days after birth. If the child was born prematurely, the newborn period is longer and extends to an early child 44 weeks after the date of conception, regardless of the date of birth. Less than half of the newborns who have seizures will have seizures later in life, but neonatal seizures are often a sign of neurological dysfunction. They are a risk factor for neonatal mortality and development of cognitive or physical disability. Depolarization means that neurons have changes in cell membranes that change their pure charge, causing cells to transmit abnormal electrical signals on top of each other. The result is a change in electrical activity in these cells, which temporarily prevents normal function. The result is different types of seizures depending on the pattern of abnormal electrical activity.

neonatal seizures occur with the highest frequency in the first 10 days after birth. Newborns who have seizures with a partThey fail, they are lethargic seizures and they seem to be generally ill. Many newborns appear to be neurologically normal among seizures; If abnormalities are recorded, they will probably be associated with a particular neurological syndrome.

There are many disorders and diseases that can cause newborn seizures. These include metabolic disorders, infections, seizure syndromes and genetic disorders. One of the common causes of seizures in newborns is ischemia, lack of oxygen. Ischemic seizures occur when the brain is free of oxygen and may develop in premature and term newborns, most often in the first three days after birth. Another common cause is intracranial bleeding, a condition that is more common in premature newborns.

neonatal intracranial infusion, such as encephalitis and meningitis, are an important cause of early newborn seizures. MetabolIic disorders that could cause seizures include dangerously low blood glucose, calcium and magnesium glucose. These disorders most often cause neonatal seizures after the first three days. Brain deformities are an unusual cause of seizures in newborns; The abnormal structure of the brain usually causes seizures later in life, but certain structural disorders may cause seizures over the first 28 days.

Beauty that occur in newborns are often treated with a tour of the tour, even if a diagnosis has not been made. The child is then monitored for several months to determine when the drugs can be safely interrupted. Diagnostic tests may include electroencephalogram for monitoring electrical activity formulas in brain and blood tests to explore the chemistry of the brain and body. Most infants also receive additional follow -ups to determine whether seizures are isolated occurrence or part of the syndrome or failure.
