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.

A sudden, brief episode (symptoms lasting only minutes) of ischemia affecting the brain is called a transient ischemic attack (TIA), often called a mini-stroke. [17] TIAs can be a warning of future strokes, with approximately 1/3 of TIA patients having a serious stroke within one year. [17] [18]
The total health care expenditure on cancer in the US was estimated to be $80.2 billion in 2015. [245] Even though cancer-related health care expenditure have increased in absolute terms during recent decades, the share of health expenditure devoted to cancer treatment has remained close to 5% between the 1960s and 2004.
Various parts of the brain may keep functioning when others do not anymore, and the term "brain death" has been used to refer to various combinations. For example, although one major medical dictionary considers "brain death" to be synonymous with "cerebral death" (death of the cerebrum ), [ 9 ] the US National Library of Medicine Medical ...
