Pseudotumor cerebri is a condition characterized by increased pressure inside the skull, mimicking symptoms of brain tumors but without the presence of an actual tumor. Common symptoms include headaches, nausea, vomiting, and pulsating sounds in the head. While the exact cause is often unknown, it may be associated with excess cerebrospinal fluid in the skull. This fluid normally cushions and protects the brain and spinal cord but can lead to increased intracranial pressure if not properly absorbed. Treatment typically involves medication, and many patients experience symptom improvement within several months to a year, often leading to discontinuation of medication under medical supervision. Weight loss is important, especially for overweight patients, to enhance recovery chances. While some patients fully recover without visual changes, others may experience permanent visual loss, ranging from mild to severe. Unfortunately, there are currently no treatments to reverse optic nerve damage caused by pseudotumor cerebri, so focus is on preventing further visual loss.
