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 .
Hypoxia (medical), abnormally low level of oxygen in the tissues Autoerotic hypoxia or erotic asphyxiation, intentional restriction of oxygen to the brain for sexual arousal; Cerebral hypoxia, a reduced supply of oxygen to the brain; Diffusion hypoxia or Fink effect, a factor that influences the partial pressure of oxygen within the pulmonary ...
G-LOC, or g-force induced loss of consciousness, is a special case of ischemic hypoxia which occurs when the body is subjected to high enough acceleration sustained for long enough to lower cerebral blood pressure and circulation to the point where loss of consciousness occurs due to cerebral hypoxia. The human body is most sensitive to ...
This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. [3] Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis.

Hypoxia, including birth hypoxia [23] Tumors; Infections; Stroke leading to infarct, which may follow thrombosis, embolisms, angiomas, aneurysms, and cerebral arteriosclerosis. [24] Neurological illness or disorders such as cerebral palsy, Parkinson's disease, etc. Surgery; Substance use disorder
Cerebral small vessel disease is a heterogeneous condition involving damage to the small blood vessels in the brain, leading to brain tissue damage and atrophy of the brain structures.
Tissue hypoxia refers to low levels of oxygen in the tissues of the body and the term hypoxia is a general term for low levels of oxygen. [2] Hypoxemia is usually caused by pulmonary disease whereas tissue oxygenation requires additionally adequate circulation of blood and perfusion of tissue to meet metabolic demands. [4]
