The Predictive Value of Cerebrospinal Fluid Dynamic Tests in Patients With the Idiopathic Adult Hydrocephalus Syndrome
Jan Malm, Bjarne Winther Kristensen, T. Karlsson, Markku Fagerlund, Jörgen Elfverson, Jan Ekstedt. Archives of Neurology, 1995-08-01
Topic: Brain imaging, connectivity and assessment
Gait was improved in 25 (72%) of the 35 patients, whereas the Bartel index remained unchanged. The conditions of five of seven patients with gait disturbance as the sole symptom improved. The spatial function (37% improved) and the findings from the Fuld object memory tests (29% improved) were significantly improved. Shunt dysfunction could not explain the lack of effect of an operation in the remaining patients. It should be noted that these results obtained at 3 months postoperatively may not be applicable in a long-term perspective. The CSF outflow conductance or CSF tap test were not able to identify those patients who would or would not benefit from a CSF diversion procedure. However patients had a lower conductance and a higher CSF pressure than did control subjects. Considerable improvement in gait was seen, but cognitive function was little affected. The CSF tap test or conductance does not provide additional information that is necessary to distinguish between patients whose conditions will or will not respond to shunting, when selection for surgery is based on conservative clinical criteria.

How this study scored 43/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 25 of the 58 points we could judge it on, which is 43 out of 100.
