ABSTRAK
Latar Belakang : Poststroke dementia merupakan bentuk demensia yang sering dijumpai yang ditegakkan 3 bulan setelah stroke. Deteksi dini berkaitan dengan kualitas hidup yang lebih baik. General Practitioner Assessment of Cognition (GPCOG) dan Memory Impairment Screen (MIS) terbukti sebagai salah satu instrumen yang paling baik dalam screening poststroke dementia dengan sensitifitas dan spesifistas yang tinggi.
Tujuan : Untuk mengetahui perbandingan akurasi diagnostik GPCOG dan MIS terhadap Mini-Cog dalam screening poststroke dementia.
Metode : Studi ini merupakan studi cross sectional dengan melibatkan 66 subjek yang mengalami stroke sekurang-kurangnya 3 bulan sebelum pengambilan data yang datang ke Rumah Sakit Umum Pusat Haji Adam Malik, Medan. Semua subjek diperiksa dengan menggunakan Mini-Cog, GPCOG dan MIS.
Hasil : Analisis diagnostik GPCOG dalam screening poststroke dementia didapatkan sensitifitas 85%; spesifisitas 68%; Nilai Duga Positif (NDP) 74%; Nilai Duga Negatif NDN) 81%; dengan akurasi 77%. Analisis diagnostik MIS dalam screening poststroke dementia didapatkan sensitifitas 97%; spesifisitas 37%; NDP 62%, NDN 92% dengan akurasi 68%.
Kesimpulan : Terdapat perbedaan akurasi yang tidak bermakna antara GPCOG dan MIS dalam screening poststroke dementia (p = 0.94).

ABSTRACT
Background : Poststroke dementia is a common type of dementia which diagnosed at least 3 months after stroke. Early detection may relate to a better quality of life of the patients. General Practitioner Assessment of Cognition (GPCOG) and Memory Impairment Scale (MIS) were proven to be the best instruments to use in screening of poststroke dementia with high sensitivity and specificity.
Objective : The aim of this study was to compare the diagnostic accuracy of GPCOG and MIS to Mini-Cog in screening of poststroke dementia. Method : This was a cross sectional study with 66 subjects who came to Haji Adam Malik General Hospital with the history of stroke at least three months before. All of the subjects were assessed with Mini-Cog, GPCOG and MIS.
Result : Diagnostic analysis of GPCOG in screening of poststroke dementia showed sensitivity 85%; specificity 68%; Positive Predictive Value (PPV) 74%; Negative Predictive Value (NPV) 81%, and accuracy 77%. And the diagnostic analysis of MIS showed sensitivity 97%; specificity 37%; PPV 62%; NPV 92%; and accuracy 68%.
Conclusion : There were an insignificant difference od diagnostic accuracy between GPCOG and MIS in screening of poststroke dementia (p = 0.94).
