Further Diagnostic Tests
The Modified Dandy Criteria is essential for diagnosing Idiopathic Intracranial Hypertension (IIH). This diagnosis applies when a patient exhibits signs of elevated intracranial pressure, including papilledema and headache, with no localizing neurological findings. Critical diagnostic tests include MRI or CT scans that show no evidence of masses or venous obstruction. Additionally, a spinal tap revealing heightened intracranial pressure (≥250 mm/H2O) and normal cerebrospinal fluid composition is necessary. Awareness of these criteria ensures timely and accurate IIH assessment.

Modified Dandy Criteria for Idiopathic Intracranial Hypertension According to the Dandy criteria, an IIH diagnosis is appropriate if a person: • has signs and symptoms of increased intracranial pressure, such as papilledema and headache;• has no localizing findings on neurological examination• has a normal MRI/CT scan with no evidence of venous obstructive disease;• has high intracranial pressure of 250mm/H2O or above on a spinal tap, with no abnormalities of cerebrospinal fluid; • is awake and alert; • has no other cause of increased intracranial pressure found.
