High intracranial pressure can cause dizziness. In some patients such as young and middle-aged patients, elevated intracranial pressure is mainly associated with dizziness and headache, accompanied by eye distention, nausea and vomiting. For the elderly, symptoms may manifest as dizziness and lightheadedness when intracranial pressure is high. The normal intracranial pressure is 80-180 mmH2O, and if the pressure is >200 mmH2O, it suggests increased intracranial pressure. Increased intracranial pressure, such as when there is inflammation in intracranial infection, or venous sinus thrombosis, such as massive cerebral hemorrhage, subarachnoid hemorrhage, and ventricular hemorrhage can cause increased intracranial pressure, such as brain metastases, which can cause edema around the tissue and cause increased intracranial pressure, dizziness, dizziness, headache, nausea, vomiting, and in severe cases, coma and impaired consciousness.
