When the blood supply to a portion of the brain is blocked this causes a stroke.
neurons die as a result of cessation of oxygen supply and dehydration causes blood viscosity. therefore if blood is viscous there would be poor oxygen supply to the brain because the hemoglobin in the blood carries the oxygen we require for cellular respiration.
the brain
The brain consumes 40% of the oxygen in your blood.
Insufficient blood supply to the brain can lead to symptoms like dizziness, confusion, fainting, and in severe cases, stroke. Without an adequate supply of oxygen and nutrients from blood, brain cells can begin to die, leading to long-term damage if not addressed promptly. It's essential to seek medical attention if you suspect a lack of blood flow to the brain.
The brain and heart require a constant supply of oxygenated blood. The brain is highly sensitive to oxygen deprivation, and even brief interruptions can lead to significant damage. The heart also needs a continuous supply of oxygenated blood to function effectively and maintain its rhythmic contractions. While the lungs and intestines also need blood supply, they do not require it as continuously as the brain and heart.
The blood vessels around the brain help supply energy for your brain

The brain needs so much blood because it needs a constant supply of it to keep up with the neurons metabolic demands. 20 percent of the blood that comes from the heart is pumped directly to the brain.
Cerebrospinal fluid is what provides as a "cushion" for the brain. (I don't understand your question regarding blood supply)
neurons die as a result of cessation of oxygen supply and dehydration causes blood viscosity. therefore if blood is viscous there would be poor oxygen supply to the brain because the hemoglobin in the blood carries the oxygen we require for cellular respiration.
25% of oxygen goes to your brain
The brain lives when it has a constant supply of blood glucose and oxygen.
the brain
The blood supply to the brain is carried by two main pairs of arteries: the internal carotid arteries and the vertebral arteries. These arteries converge at the base of the brain to form the circle of Willis, which helps ensure a continuous supply of blood to the brain. The blood vessels in the brain are highly specialized and form a complex network to deliver oxygen and nutrients to brain cells.
