Hypoxic-ischaemic injury to the brain is the commonest cause of permanent neurodevelopmental disability in the very preterm and other children who survive after neonatal intensive care. Non-invasive techniques are therefore needed to examine the mechanisms of damage to the brain. Near infrared spectroscopy provides continuous cot-side information about cerebral oxygenation and metabolism in sick preterm infants by measurements of oxyhaemoglobin, deoxyhaemoglobin and oxidized cytokrom aa3. The cytokrome aa3 signal may, however, be artifactual due to interference from oxyhaemoglobin. Future investigations may clarify this problem.

D001925 Brain Damage, Chronic A condition characterized by long-standing brain dysfunction or damage, usually of three months duration or longer. Potential etiologies include BRAIN INFARCTION; certain NEURODEGENERATIVE DISORDERS; CRANIOCEREBRAL TRAUMA; ANOXIA, BRAIN; ENCEPHALITIS; certain NEUROTOXICITY SYNDROMES; metabolic disorders (see BRAIN DISEASES, METABOLIC); and other conditions. Encephalopathy, Chronic,Chronic Encephalopathy,Chronic Brain Damage
D002534 Hypoxia, Brain A reduction in brain oxygen supply due to ANOXEMIA (a reduced amount of oxygen being carried in the blood by HEMOGLOBIN), or to a restriction of the blood supply to the brain, or both. Severe hypoxia is referred to as anoxia and is a relatively common cause of injury to the central nervous system. Prolonged brain anoxia may lead to BRAIN DEATH or a PERSISTENT VEGETATIVE STATE. Histologically, this condition is characterized by neuronal loss which is most prominent in the HIPPOCAMPUS; GLOBUS PALLIDUS; CEREBELLUM; and inferior olives.

D002545 Brain Ischemia Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION. Cerebral Ischemia,Ischemic Encephalopathy,Encephalopathy, Ischemic,Ischemia, Cerebral,Brain Ischemias,Cerebral Ischemias,Ischemia, Brain,Ischemias, Cerebral,Ischemic Encephalopathies
D002658 Developmental Disabilities Disorders in which there is a delay in development based on that expected for a given age level or stage of development. These impairments or disabilities originate before age 18, may be expected to continue indefinitely, and constitute a substantial impairment. Biological and nonbiological factors are involved in these disorders.
