Cognitive functions refer to mental processes such as memory, attention, language, and problem-solving. Brain tumors can impair these functions in several ways:
Direct Compression: Tumors can directly compress brain tissue, disrupting normal neural function. Increased Intracranial Pressure: Growing tumors can increase pressure within the skull, leading to headaches, nausea, and cognitive deficits. Disruption of Blood Flow: Tumors can obstruct blood vessels, leading to areas of ischemia and subsequent cognitive impairments. Inflammation and Edema: Tumors often cause inflammation and swelling, further impairing brain function.
