Hypovolemia, also known as volume depletion or volume contraction, is a state of abnormally low extracellular fluid in the body. [1] This may be due to either a loss of both salt and water or a decrease in blood volume. [2] [3] Hypovolemia refers to the loss of extracellular fluid and should not be confused with dehydration.

Brain oedema formation is due to the breakdown of red blood cells, where haemoglobin and other contents of red blood cells are released. The release of these red blood cells contents causes toxic effect on the brain and causes brain oedema. Besides, the breaking down of blood-brain barrier also contributes to the odema formation. [13]
Cerebral edema is commonly seen in a variety of brain injuries including ischemic stroke, subarachnoid hemorrhage, traumatic brain injury, subdural, epidural, or intracerebral hematoma, hydrocephalus, brain cancer, brain infections, low blood sodium levels, high altitude, and acute liver failure.
The cerebral blood volume maps can be calculated by dynamic magnetic resonance image set obtained by echo planar imaging after intravenous injection of thiol contrast agent. [7] Planar imaging techniques or single high-speed shots provide the necessary resolution for contrast agents to display rapid brain blood movements. [ 8 ]
Severe trauma can cause SAH in all parts of the brain. When the SAH volume is large, rarely it can cause cerebral infarction a few days after trauma due to arterial vasospasm. Although CT scan is performed more often than MRI to detect SAH, MRI is more sensitive than CT in this aspect.
“While green tea is generally safe, excessive consumption (over 3-4 cups per day) may cause side effects like insomnia, gastrointestinal distress, or liver damage due to high caffeine or ...
Cerebral atrophy can be hard to distinguish from hydrocephalus because both cerebral atrophy and hydrocephalus involve an increase in cerebrospinal fluid (CSF) volume. In cerebral atrophy, this increase in CSF volume comes as a result of the decrease in cortical volume. In hydrocephalus, the increase in volume happens due to the CSF itself. [20]
If you have low testosterone, it can lead to problems with drive, muscle mass levels, fat distribution, bone density, and even red blood cell production. These signs and symptoms may vary in ...
