Intracranial Hypertension is diagnosed in many different ways. It can be diagnosed through, CT/CAT scans, MRI scans which are more detailed than CT or CAT scans. However, it is usualy diagnosed via an eyetest, looking at the back of the eyes and optic nerves and also by a Lumbar Puncture/Spinal Tap procedure which involves a needle into the spinal cord, where the CFS fluid is and taking a opening pressure reading. The normal reading is 25 at the highest and anything higher indicates IIH or another condition such as meningitis, disorders of the Central Nervous System such as Guillain-Barre Syndrome, multiple sclerosis and also cancer of the brain and spinal cord. These are found via the spinal fluid which is taken out during the procedure and sent off for testing.
Neurology specialists are essential for this condition as IIH is a neurological condition.
