Crude prevalence had decreased to 1.81 per 1000 live births (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.0067). Gestational age\u2010specific prevalence for &lt;28 gestational weeks was 74.8 per 1000 live births, 46.6 for 28\u201331\u2009weeks, 5.8 for 32\u201336\u2009weeks and 1.1 per 1000 for &gt;36\u2009weeks of gestation. Hemiplegia, found in 36.2%, had declined (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.03). Diplegia was found in 36.2% and tetraplegia 5.3%. Dyskinetic CP accounted for 18.6% and ataxia for 3.7%. Neuroimaging revealed maldevelopments in 14%, white matter lesions in 44%, cortical\/subcortical lesions in 13% and basal ganglia lesions in 17%. Prenatal aetiology was considered in 34%, peri\u2010 or neonatal in 48%, while in 18% aetiological period remained unclassified. Motor outcome in children who needed neonatal care had improved (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.04).
