Diagnosis
Diagnosis of IH is by scan and measurement of the CSF pressure.
On CT scan, the ventricles (chambers in the brain) will usually appear normal or small.
The CSF pressure should always be measured despite the “normal” scan results. It will be found to be raised on lumbar puncture.
On examining the eyes, papilloedema (swelling of the optic disc) may be present.
This in itself is often an indication for surgical intervention.
As most people with IH appear perfectly normal, they often do not receive the recognition they deserve.
But IH can be very disabling.
Relationships suffer. Headache can be constant, thus disturbing normal sleep patterns. Depression is not uncommon.
