What are some common signs of increased intracranial pressure?

Increased intracranial pressure (ICP) refers to a rise in pressure within the skull and can lead to serious complications if not addressed. The signs associated with increased ICP are primarily related to changes in brain function and pressure on the structures within the skull.

Headache is a classic symptom of increased ICP. The pressure can irritate the brain and its coverings, leading to the sensation of pain. Blurred vision occurs because increased pressure can affect the optic nerve or the brain regions involved in visual processing, potentially leading to visual disturbances. Hypertension can also manifest, particularly as a compensatory response; the body may increase systemic blood pressure in an attempt to maintain cerebral perfusion in the presence of elevated ICP.

The other options list symptoms that are not directly linked to increased intracranial pressure. Loss of appetite, fatigue, and irritability may arise from various conditions but are nonspecific and less directly related to changes in intracranial dynamics. Weight gain, memory loss, and insomnia can indicate other conditions such as endocrine or mental health issues, but they do not align closely with classic signs of increased ICP. Joint pain, rash, and fever suggest possible systemic or infectious processes rather than neurologic issues stemming from elevated intracranial pressure.
