Like an adult’s, a baby’s skull is made up of several bones. However, at birth these bones have not yet fused together. This allows the head to be moulded, which makes for an easier delivery. In the months following birth, the bones of the skull settle and fuse together, creating a hard shell that protects the brain. Before the bones fuse, a baby’s brain is at its most vulnerable.</p><p>The brain is also surrounded by fluid. Cerebrospinal fluid (CSF) is found both around the brain and spinal cord and in cavities deep within the brain, called ventricles. This system of CSF nourishes the brain and cushions it from knocks. The ventricles themselves are surrounded by brain tissue and blood vessels that deliver oxygen to the brain. In a premature baby, these blood vessels are thin and weak, and are vulnerable to injury.</p><h2>Diagnosis of brain injuries and damage</h2><p>Although rare, the premature baby’s brain can be injured during pregnancy, during labour, immediately after birth, and during the first few weeks of life. In general, brain injuries occur:</p><ul><li>when the brain does not receive enough oxygen or glucose</li><li>when blood vessels in the brain rupture, causing bleeding</li><li>in rare cases, if the brain receives a knock or a blow of some kind</li></ul><p>Diagnosing brain injuries can be complex. As the brain is in many ways the control centre for the rest of the body, problems in the brain can create symptoms in other parts of the body. However, on occasion the brain injury is quite silent with no obvious signs. Moreover, while an immediate diagnosis of brain injury may be possible, a longer term prognosis may not be. For example, if a baby has sustained a brain injury which causes bleeding, the symptom of the bleeding itself may be quickly diagnosed and treated. However, if the bleeding has caused irreversible brain damage, the symptoms and signs of a longer term disability, such as cerebral palsy, may not be apparent for some time.</p><p>Injuries to the brain can be large or small. However, it is often the location of the injury that determines how severe its effects will be, especially in the long-term. Brain function can be highly plastic, at times a large injury can be overcome as the brain establishes new pathways to send and receive commands. At other times, the brain will not be able to overcome a smaller injury and lasting damage will occur. Diagnosing and predicting the outcomes of these longer term effects can be very difficult, if not impossible, in the early days of a premature baby’s life.</p><p>Imaging technologies such as head ultrasound (HUS) and magnetic resonance imaging (MRI) will be used to make a definitive diagnosis of brain injury. Head ultrasounds are performed routinely in the first week of a premature baby’s life. If problems with the brain are suspected, these diagnostic imaging scans will continue as needed. Depending on the nature and severity of the injury, a simple visual inspection of the head can give an indication of a problem. For example, if a premature baby is bleeding in the brain, their head may visibly swell.</p><p>Although some brain injuries may have no symptoms at first, over time the baby may develop seizures, may have abnormal behaviour, or may not respond to stimulation in a normal way.</p><h4>More information</h4><ul><li> <a href="/Article?contentid=1771&language=English">Brain and behaviour concerns in premature babies</a></li><li> <a href="/Article?contentid=1846&language=English">Treatment of Brain and behaviour problems in premature babies</a> </li><li> <a href="/Article?contentid=1865&language=English">Ongoing care of brain and behaviour problems in premature babies</a> </li></ul>https://assets.aboutkidshealth.ca/akhassets/preemie_inside_isolette1_BR_EN.jpgDiagnosis of brain and behaviour problems in premature babies
