Cerebral hypoxia is a form of hypoxia (reduced supply of oxygen), specifically involving the brain; when the brain is completely deprived of oxygen, it is called cerebral anoxia. There are four categories of cerebral hypoxia; they are, in order of increasing severity: diffuse cerebral hypoxia (DCH), focal cerebral ischemia , cerebral infarction ...
Many psychological measures for autism assess stability over time. However, with the rise of various preventative programs for autism, there is an increased need for these measures to assess change over time. [6] Additionally, not all measures orientated towards infants and toddlers are appropriate for older children as they continue to develop.
Sleep problems in autism have been linked in a study to brain changes, particularly in the hippocampus, though this study does not prove causation. [66] A common presentation of sleep apnea in children with autism is insomnia. [67] All known genetic syndromes which are linked to autism have a high prevalence of sleep apnea.
Prolonged hypoxia induces neuronal cell death via apoptosis, resulting in a hypoxic brain injury. [34] [35] Oxygen deprivation can be hypoxic (reduced general oxygen availability) or ischemic (oxygen deprivation due to a disruption in blood flow) in origin. Brain injury as a result of oxygen deprivation is generally termed hypoxic injury.
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder "characterized by persistent deficits in social communication and social interaction across multiple contexts" and "restricted, repetitive patterns of behavior, interests, or activities". [11] Sensory abnormalities are also included in the diagnostic manuals ...
Hypoxia refers to deficiency of oxygen, Ischemia refers to restriction in blood flow to the brain. The result is “encephalopathy” which refers to damaged brain cells. Encephalopathy is a nonspecific response of the brain to injury which may occur via multiple methods, but is commonly caused by birth asphyxia, leading to cerebral hypoxia. [2 ...
Among these measurements, the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) are considered the "gold standards" for assessing autistic children. [ 24 ] [ 25 ] The ADI-R is a semi-structured parent interview that probes for symptoms of autism by evaluating a child's current behavior and ...
Secondly, to understand the nature of any brain injury or resulting cognitive problem (see neurocognitive deficit) and its impact on the individual, as a means of devising a rehabilitation programme or offering advice as to an individual's ability to carry out certain tasks (for example, fitness to drive, or returning to work). And lastly ...
