All of the above.
They will suffer a stroke and have irreversable brain damage.
Stroke is a medical condition where part of the brain dies as a result from a blood clot. The blod clot blocks the flow of blood to the part, depriving that part of the brain with oxygen and nutrients. As such, paralysis of body parts which that part of the brain controls, ensues.
The blood brain barrier blocks chemicals from entering brain tissue.
A blood clot that blocks an artery to the brain can cause a stroke. If the clot blocks blood flow to the lungs pulmonary embolism can occur. A blood clot that blocks a coronary artery can cause a heart attack.

The brain cells would suffer the most if glucose blood levels were to drop drastically because they rely heavily on glucose for energy. Without an adequate supply of glucose, the brain may not function properly and could lead to symptoms such as dizziness, confusion, and even loss of consciousness.
It blocks the blood flow in your body causing a lack of oxygen to your brain.
"A stroke" is the answer you're looking for.
no the brain needs the oxygen from the blood fromt the heart to survive
If self inflicted, addiction, it can give you a "high" similar to cutting.It can lead to cardiac/respiratory arrest(death).Strangled victims can suffer from memory loss of the particular strangulation period and may suffer from a croaky voice due to the extended windpipe blockage It blocks the blood-flow to your brain and heart, since the blood carries oxygen to the brain and heart, blocking it will lead to death, the body needs oxygen.I would not recommend strangling yourself, it does not solve anything and if you fail, you will most probably end up in a mental asylum...PLEASE DO NOT STRANGLE YOURSELF!
The chemical balance between your brain to blood transplant needs to adhere with water. But if it does not, dehydration occurs. Dehydration is a condition of where the person of experience accounts to the loss of oxygen, which makes it hard to breath. In simpler terms a person dehydrates from the lack of water entering the system.
If a person's heart stops beating - and nothing is done to try to restart it - they will suffer irreparable brain damage - and possibly death.
