On the outside of the body, this information comes in the form of sight, sounds, smells, and so on. Within the brain, this information takes the form of electrical signals passed on by specialized cells called neurons. These signals are usually ordered: the body detects something hot, and the brain interprets the signal and sends another signal for the body to pull away. During a seizure, the brain misfires, sending overwhelming amounts of conflicting signals through the brain at the same time. </p><p>Although the cause of seizures is not fully understood, a premature baby is at higher risk for seizures if they:</p><ul><li>have experienced severe asphyxia in the womb or during birth </li><li>have severe bleeding within the skull, called intracranial hemorrhage. </li><li>have a stroke </li><li>have a metabolic imbalance such as decreased levels of sodium or glucose, which can be due to the immaturity of the kidneys, hormones, or metabolic systems </li><li>have an infection such as meningitis </li></ul><p>In adults, seizures can take many forms, some extreme. For example, some people may lose consciousness and go into convulsions during a seizure. Babies, however, generally do not exhibit these more extreme physical manifestations of seizures. When a premature baby has a seizure, it is usually a much more subtle event. Usual signs include: </p><ul><li>apnea, or absence of breathing effort </li><li>twitching of the arms or legs </li><li>fluttering of the eyelids </li><li>arching of the back </li><li>rhythmic arm or leg movements, sometimes characterized by a swimming, rowing, or pedalling motion </li></ul><p>In addition to the subtlety of a premature baby’s signs of seizure, these symptoms can be due to other factors and can occur in normal healthy babies. This can make diagnosis more difficult. Moreover, a premature baby may just have one episode; while staff may notice the behaviour and suspect a seizure, if it never happens again, it may not be possible to confirm the diagnosis. </p><p>During a seizure, the brain uses up a considerable amount of energy. Oxygen and glucose consumption is high, and in some cases ends up depriving the brain of those essential substances. For this reason, long, sustained seizures are more potentially harmful than brief episodes. </p><p>Because the symptoms of a seizure are subtle and mimic other conditions and normal behaviour, technology is used to confirm the event. Typically, these include bedside monitoring with cerebral functioning monitor (CFM), formal electroencephalogram (EEG), video EEG, head ultrasound, computed tomography (CT) of the head, and magnetic resonance imaging (MRI). </p><p>Blood work will also be done to establish whether infection or a metabolic disorder is playing a role.</p><p>More information</p> <ul><li> <a href="/Article?contentid=1773&language=English">Seizures in premature babies</a></li><li> <a href="/Article?contentid=1846&language=English">Treatment of seizures in premature babies</a></li></ul>Diagnosis of seizures in premature babies
