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 ...
Signs and symptoms are not mutually exclusive, for example a subjective feeling of fever can be noted as sign by using a thermometer that registers a high reading. [7] Because many symptoms of cancer are gradual in onset and general in nature, cancer screening (also called cancer surveillance) is a key public health priority. This may include ...
Altered brain structure in chemotherapy patients provides explanation for cognitive impairment. [12] Another study in 2007 investigated the differences in brain structure between two adult, monozygotic twin females. One underwent chemotherapy treatment for breast cancer, while the other did not have cancer and was not treated with chemotherapy.
In normal conditions, an increased demand for oxygen is easily compensated by an increased cerebral blood flow. but under conditions when there is insufficient oxygen available, increased blood flow may not be sufficient to compensate, and hypoxia can result in brain injury.
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
This mighty mineral courses through our veins, quite literally, playing a pivotal role in transporting oxygen and keeping our energy levels from dipping lower than our mid-day motivation at work ...
The symptoms vary widely, as do the treatments. Central nervous system tumors are the most common forms of pediatric cancer. Brain tumors are the most frequent and have the highest mortality. [4] Some disorders, such as substance addiction, autism, and ADHD may be regarded as CNS disorders, though the classifications are not without dispute.
