Final answer:
The statement is true; a brain tumor can cause increased intracranial pressure resulting in various neurological symptoms and potentially leading to permanent brain damage.
Step-by-step explanation:
The statement, "The signs and symptoms of a brain tumor occur because of increased intracranial pressure," is true. A brain tumor can indeed lead to increased intracranial pressure because the skull is a rigid structure that allows for very little expansion. When a tumor grows within this confined space, it presses against brain tissues and can restrict the flow of cerebrospinal fluid. This pressure build-up can cause various neurological symptoms, such as headaches, changes in vision, nausea, vomiting, seizures, cognitive or personality changes, and other neurological impairments, depending on the tumor's location within the brain. It can also lead to permanent brain damage if not treated in a timely manner.
