Blood Clot in the brain is also known as cerebral thrombosis or cerebral embolism, which is considerably one of the most serious medical conditions. This is the condition when there is blood lump in one of the brain’s blood vessels, which restricts the flow of blood in brain. The human brain needs constant oxygen and nutrients to progress in the most efficient way. Sudden blockage of this blood flow results in killing the brain cells, which then disturbs the entire body system, resulting in a medical emergency.
