Prior to operation a cerebrospinal fluid tap-test (CSF-TT) was performed with measurements of gait pattern and psychometric functions (memory, visuo-motor speed and visuo-constructive skills) before and after the removal of 50 ml CSFby lumbar puncture (LP). Fifteen patients improved and 3 were unchanged after surgery. Short duration of disease, gait disturbance preceding mental deterioration, wide temporal horns and small sulci on CT-scan were associated with good outcome after shunting. There was a good correlation between the results of CSF-TT and shunt surgery (X\u00b2 = 4,11 ,phi = 0.48, p &lt; 0.05), with gait test showing highest correlation (r = 0.99, p = 0.01). In conclusion, this version of CSF-TT proved to be an effective test to predict improvement after shunting in patients with NPH.<\/jats:p>","DOI":"10.1590\/s0004-282x1997000200003","type":"journal-article","created":{"date-parts":[[2010,10,28]],"date-time":"2010-10-28T02:08:34Z","timestamp":1288231714000},"page":"179-185","source":"Crossref","is-referenced-by-count":52,"title":["The predictive value of cerebrospinal fluid tap-test in normal pressure hydrocephalus"],"prefix":"10.1590","volume":"55","author":[{"given":"Benito P.","family":"Damasceno","sequence":"first","affiliation":[{"name":"Universidade Estadual de Campinas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edmur F.","family":"Carelli","sequence":"additional","affiliation":[{"name":"Universidade Estadual de Campinas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donizeti C.","family":"Honorato","sequence":"additional","affiliation":[{"name":"Universidade Estadual de Campinas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose J.","family":"Facure","sequence":"additional","affiliation":[{"name":"Universidade Estadual de Campinas"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1056\/NEJM196507152730301","article-title":"Fisher CM: Hakim S.
