The aim of this research is examination of effects of modified core exercise studies in Alzheimer’s patients over 55 years of age on depression, daily life activities and some physical fitness values. For the study, the consent form was signed by people who have Alzheimer's 1st and 2nd stage report and their relatives and then modified core exercise studies were applied to Alzheimer’s patients over 55 years of age. There are totally 42 Alzheimer’s patients including experimental (n=21) and control groups (n=21). Control group was only marched and their continuity of daily life activities was observed. Subject group was only made modified core exercises for 1 hour four days a week during a total of 12 weeks. The study was conducted in Gaziantep Moral Home Alzheimer’s Center. The study model consists of pre-test and post-test methods. Weight, height, body mass index and age parameters of the Alzheimer’s patients were determined. Measurements of patients’ reactions, Mini Mental Test Yesavage Geriatric Depression Scale, Katz Daily Life Activities Scale, Mini Nutritional Assessment Form and measurements of functional reach flexibility were taken. After 12 weeks at the end of these modified core exercises, the same measurements were taken from both groups. Statistically, there were no significant difference in height, weight and body mass index data of experimental and control groups. According to the study findings, groups created before the research were homogeneous in terms of all measurements apart from functional reach value when pre-test and post-test values of control groups were compared. Before the study, the differentiation (p .05). As a result of experiment, there were significant differences (p 0,05). Calisma bulgularina gore kontrol grubunun on test ve son test degerleri karsilastirildiginda, arastirma oncesinde olusturulan gruplar fonksiyonel uzanma degeri disinda tum olcumler acisindan homojendir. Arastirma oncesinde fonksiyonel uzanma testinde kontrol grubu lehine tespit edilen farklilasma (p .05). Deney sonucunda Katz Gunluk Yasam Aktiviteleri Olcegi, Yesavage Geriatrik Depresyon Skalasi (Kisa Formu) ve Mini Nutrisyonel Degerlendirme Formu skorlarinda deney grubu lehine anlamli farklar ortaya cikmistir (p<.001). Deney grubunun on ve son test olcumu sonucunda grubun sag el reaksiyon (ses) ve sol el reaksiyon (karisik) degerleri (p<.01) ile sag el reaksiyon (karisik) degerlerinde ilerlemeler kaydedilmistir (p<.05). Deney grubunun on ve son test olcumu sonucunda fonksiyonel uzanma, Katz Gunluk Yasam Aktiviteleri Olcegi, Yesavage Geriatrik Depresyon Skalasi (Kisa Formu) ve Mini Nutrisyonel Degerlendirme Formu skorlarinda gelisimler tespit edilmistir (p<.001).Kontrol grubunun on ve son test olcumu sonucunda sag el reaksiyon (isik) degeri (p<.01) ile sol el reaksiyon (isik) ve sag el reaksiyon (ses) degerlerinde gerilemeler tespit edilmistir (p<.05).Kontrol grubunun on ve son test olcumu sonucunda fonksiyonel uzanma ve Yesavage Geriatrik Depresyon Skalasi (Kisa Formu) degerleri (p<.01) ile Egitimsizler icin Standardize Minimental Test ve Mini Nutrisyonel Degerlendirme Formu skorlarinda anlamli dususler kaydedilmistir (p<.05).
