-This report describes the case of an elderly physician who endured a slowly progressive, ambulatory illness, which was erroneously diagnosed as Parkinson's disease. After ten years of progressive illness the correct diagnosis of normal pressure hydrocephalus (NPH) was finally made, revealing itself, by accident, through incontinence and mild dementia. The patient-physician enjoyed an instantaneous remission induced by a large lumbar puncture (LP) sustained by a ventriculosystemic shunt. The patient-physician dedicated his renewed life to informing the medical profession about this dramatic syndrome, which he believes is more common and more reversible than generally thought. Although the patient had been virtually restored to normal, a series of complications typical of ventriculosystemic shunting (VSS) occurred, including significant hearing loss and subdural haematoma (SDH). The patient feels, however, that his clinical improvement far outweighs the complications and that every patient with NPH should have the opportunity to decide whether or not to have a VSS.

“…137) Additionally, a study limited to iNPH patients reported improvement of symptoms in 55% of all cases with normal RI cisternography. 17) RI cisternography predicted shunt responsiveness less accurately than repeated lumbar CSF tap test or lumbar external CSF drainage, 61) and the use of RI cisternography did not add any additional information. 16) Because of the invasiveness and low diagnostic accuracy of CT or RI cisternography, it is not necessary for the diagnosis of iNPH (Recommendation grade C2); however, it may be useful in identifying obstructions in the circulation of CSF.…”

Among the various disorders manifesting dementia, gait disturbance, and urinary incontinence in the elderly population, idiopathic normal pressure hydrocephalus (iNPH) is becoming of great importance. After the publication of the first edition of the Guidelines for Management of Idiopathic Normal Pressure Hydrocephalus in 2004 (the English version was published in 2008), clinical awareness of iNPH has risen dramatically, and the number of shunt surgeries has increased rapidly across Japan. Clinical and basic research on iNPH has increased significantly, and more high-level evidence has since been generated. The second edition of the Japanese Guidelines was thus published in July 2011, to provide a series of timely evidence-based recommendations related to iNPH. The revision of the Guidelines has been undertaken by a multidisciplinary expert working group of the Japanese Society of Normal Pressure Hydrocephalus in conjunction with the Japanese Ministry of Health, Labour and Welfare research project on``Studies on the epidemiology, pathophysiology, and treatment of normal pressure hydrocephalus.'' This English version of the second edition of the Guidelines was made to share these ideas with the international community and to promote international research on iNPH.

“…It has been suggested that ACs may cause a potentially abnormal elevated CSF pressure, which may lead to hearing loss, as observed in normal-pressure hydrocephalus [27] because intracranial pressure changes can be conducted to the inner ear via a patent cochlear aqueduct [28]. Furthermore, localized impingement of the AC on the eighth cranial nerve [16], and vascular compromise with interruption of the cochlear blood supply [29] have also been proposed as mechanisms of hearing loss.Another possible explanation would be a multifactorial cause.…”

Hearing Loss Attributable to a Cerebellopontine-Angle Arachnoid Cyst in a Child

Although hearing loss in newborns and infants is predominantly due to malformations and infections, there are other situations which may compromise hearing quality in later stages, including posterior-fossa arachnoid cysts (ACs). We report the case of an 8-year-old girl who presented with hearing loss linked to a pontocerebellar-angle AC which had been diagnosed and treated when she was 14 months old. The pathophysiology of this late AC complication is discussed. This case reminds us that a close follow-up with audiologic monitoring and/or brain stem auditory evoked response is necessary in children with posterior-fossa AC because modern neuroradiological imaging methods do not inform about cerebral and nerve functions, although they provide excellent morphological details of ACs and have improved the ease and accuracy of their early diagnosis. Therefore, surgery should be performed before complete hearing loss occurs; however, in hearing-impaired patients, it remains unclear which surgical treatment is most appropriate.

Analysis of hearing loss after shunt placement in patients with normal-pressure hydrocephalus

Abstract: Although shunt insertion for treatment of NPH results in a decrease in hearing, most of the loss can be recovered.
