The status of children without cerebral palsy was ranked into categories of major, minor and no developmental impairments.<\/jats:p><jats:p>Results: At the time of the last follow\u2010up examination 17% of the children showed a major impairment including 9% cerebral palsy, 42% a minor impairment and 41% were normally developed. The longitudinal analysis of cases without cerebral palsy reveals that an assessment \u2018at term\u2019 can only give the correct developmental prognosis in 49% of the cases. At the corrected age of 12 months the prognosis is correct in 59% of the cases, whereas at the corrected age of 3 years 70% proves to be right. Diagnosis of cerebral palsy could be confirmed at the corrected age of 2 years with sufficient reliability.<\/jats:p><jats:p>Conclusion: The neurodevelopmental evaluation of former preterm infants with a birth weight &lt;1000 g demands a follow\u2010up period of at least 6 years in order to make reliable statements. We are doubtful that follow\u2010up testing completed prior to this age can yield reliable results.<\/jats:p>","DOI":"10.1111\/j.1651-2227.2006.00130.x","type":"journal-article","created":{"date-parts":[[2008,4,30]],"date-time":"2008-04-30T21:00:00Z","timestamp":1209589200000},"page":"342-347","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":57,"title":["Neurodevelopmental outcome in extremely low birth weight infants: what is the minimum age for reliable developmental prognosis?"],"prefix":"10.1111","volume":"96","author":[{"given":"Wolfgang","family":"Voss","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Achim\u2010Peter","family":"Neubauer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Wachtendorf","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Janko F.","family":"Verhey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evelyn","family":"Kattner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,2,23]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1136\/fn.85.3.F159"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/fn.73.3.F143"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1136\/fn.77.2.F91"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1001\/archpedi.154.7.725"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2005-0173"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(05)80043-5"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8749.1990.tb08117.x"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(05)80045-9"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa041367"},{"key":"e_1_2_5_11_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.289.24.3264"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.105.6.1216"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1998.tb01413.x"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200008103430601"},{"key":"e_1_2_5_15_2","first-page":"18","article-title":"Neurodevelopmental outcome of extremely low birth weight infants in Maryland","volume":"46","author":"Blitz RK","year":"1997","journal-title":"Md Med J"},{"key":"e_1_2_5_16_2","volume-title":"Bayley Scales of Infant Development","author":"Bayley N","year":"1993"},{"key":"e_1_2_5_17_2","volume-title":"Kaufman Assessment Battery for Children","author":"Kaufman AS","year":"1983"},{"key":"e_1_2_5_18_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8749.1994.tb11808.x"},{"key":"e_1_2_5_19_2","first-page":"345","article-title":"Neurodevelopmental and school performance of very low\u2010birth\u2010weight infants: a seven\u2010year longitudinal study","volume":"76","author":"Vohr BR","year":"1985","journal-title":"Pediatrics"},{"key":"e_1_2_5_20_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1993.tb12720.x"},{"key":"e_1_2_5_21_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8749.1990.tb08542.x"},{"key":"e_1_2_5_22_2","volume-title":"Association for Research in Infant and Child Development","author":"Griffith R","year":"1976"},{"key":"e_1_2_5_23_2","volume-title":"Griffith Entwicklungsskalen (GES) zur Beurteilung der Entwicklung in den ersten beiden Lebensjahren","author":"Brandt I","year":"1983"},{"key":"e_1_2_5_24_2","volume-title":"M\u00fcnchener Funktionelle Entwicklungsdiagnostik, 2. und 3.
