Final answer:
Increased pressure inside the skull due to brain tissue swelling can lead to decreased blood flow and various complications.
Step-by-step explanation:
When pressure inside the skull increases due to brain tissue swelling, blood flow is decreased. This can result in a variety of symptoms and complications, depending on the specific condition causing the increased pressure. For example, in a hemorrhagic stroke, bleeding into the brain can cause physical pressure on the brain tissue, leading to loss of function and compromised blood flow. Similarly, in conditions such as meningitis and encephalitis, inflammation can cause intracranial pressure, resulting in severe damage to the brain tissues.
