Telah dilakukan penelitian mengenai tingkat kecerdasan pasien anak penyandang kelumpuhan otak (CP) di Yayasan pembinaan anak cacad (YPAC) Medan, dengan menghubungkan antara jenis CP, derajat retardasi mental, serta jenis kelamin. Penelitian dilaksanakan secara potong lintang, meliputi semua pasien dengan CP yang terdaftar dalam buku registrasi poliklinik YPAC Medan antara Juli 1987-Juni 1998. Semua di antara 74 pasien yang diikutsertakan dalam penelitian ini mempunyai IQ di bawah rata-rata dan 62% di antaranya berjenis perempuan. Jenis yang paling banyak ialah tipe spastik (65%), kemudian campuran (16%), diskinetik (11%) dan hipotonik (8%). Secara keseluruhan, golongan CP campuran mempunyai derajat retardasi mental paling berat. Secara statistik terdapat hubungan bermakna antara jenis CP dengan tingkat retardasi mental (P < 0.001), dan tak terdapat hubungan bermakna antara jenis CP dengan jenis kelamin.
