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 ...
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 ...
Further, symptoms can last from a few seconds to a few minutes or extended periods of time. If the brain becomes damaged irreversibly and infarction occurs, the symptoms may be permanent. [9] Similar to cerebral hypoxia, severe or prolonged brain ischemia will result in unconsciousness, brain damage or death, mediated by the ischemic cascade. [10]
Other common causes of chronic organic brain syndrome sometimes listed are the various types of dementia, which result from permanent brain damage due to strokes, [7] Alzheimer's disease, or other damaging causes which are irreversible. Amnestic pertains to amnesia and is the impairment in ability to learn or recall new information, or recall ...
Generally, diseases outlined within the ICD-10 codes F00-F09 within Chapter V: Mental and behavioural disorders should be included in this category. Subcategories This category has only the following subcategory.
Reperfusion injury plays a major part in the biochemistry of hypoxic brain injury in stroke. Similar failure processes are involved in brain failure following reversal of cardiac arrest ; [ 3 ] control of these processes is the subject of ongoing research.
Hypoxia, lack of oxygen to the brain, can also cause damage in the cerebral motor cortex and other brain regions. This lack of oxygen can be the result of placenta malfunction, womb rupture, umbilical cord damage, low maternal blood pressure or asphyxia during labor and delivery. [4]
In April 2021, a group at Kyoto University reported a case of Lance Adams syndrome 11 years after onset due to hypoxic encephalopathy caused by a bronchial asthma attack, and in March 2022, a group at Kitasato University reported a case of Lance Adams syndrome after a hanging neck injury 1 year and 6 months after onset. There are an increasing ...
