Edukasi pencegahan demensia pada lansia penting untuk meningkatkan pengetahuan dan sikap lansia terhadap upaya pencegahan demensia. Implementasi program edukasi pencegahan demensia dilihat berdasarkan upaya peningkatan aktifitas fisik, sosial, kognitif dan gizi lansia di wilayah Puskesmas Kecamatan Jatinegara. Penelitian ini adalah penelitian kualitatif dengan desain deskriptif menggunakan teori implementasi kebijakan Edward III. Pengumpulan data melalui indepth interview, focus group discussion dan observasi. Hasil penelitian ini adalah program edukasi pencegahan demensia sudah berjalan namun belum optimal dari sisi komunikasi, sumber daya, disposisi, dan struktur birokrasi. Selain itu, lansia memiliki risiko tinggi terkena demensia sedangkan pengetahuan mengenai demensia masih kurang. Hal ini dikarenakan fokus program saat ini adalah skrinning pencatatan dan pelaporan jumlah lansia berdasarkan perintah Kemenkes RI. Saran penelitian ini adalah meningkatkan koordinasi dan komitmen seluruh pelaksana dan pemangku kebijakan untuk menjadikan upaya pencegahan demensia sebagai prioritas program.
