Amaç: Uyku bozukluğu demansın değişik formlarında ortaya çıkmaktadır. Bu çalışmada demans hastalarında galantamin ve donepezil'i n uyku bozukluklarına olan etkilerini araştırmak amaçlanmıştır.

Yöntem: Çalışmada, Ocak 2008-Aralık 2010 tarihleri arasında Geriatri polikliniğine başvuran olgular incelenmiştir. Değerlendirmeye demans tanısı konularak tedavi başlanan olgular alınmıştır. Çalışmaya, başlangıçta uyku bozukluğu tespit edilen 38 demans hastası (27 kadın, 11 erkek) dâhil edilmiştir. Bu demans hastaları klinisyenin görüşü doğrultusunda galantamin (n=22) veya donepezil (n=16) ile tedavi edilmişlerdir. Uyku bozukluğuna yönelik hazırlanmış olan sorular başlangıçta ve 24. haftada olgulara ve/veya yakınlarına yöneltilerek değerlendirmeleri yapılmıştır.

Bulgular: Gruplar arasında tanımlayıcı özellikler bakımından fark yoktu (p>0,05, tüm karşılaştırmalar için). Bilişsel fonksiyonları değerlendirmek amacıyla yapılan testlerin skorlarında başlangıçtan 24. haftaya kadar meydana gelen değişiklikler bakımından iki ilaç grubu içinde karşılaştırıldığında anlamlı farklılık olmadığı görülmüştür (p>0,05, tüm karşılaştırmalar için). Tekli lojistik regresyon analizinde, galantamin'i n donepezil'e göre uyku bozukluğu üzerine olumlu etkisinin yaklaşık 5 kat daha fazla olduğu ve bunun anlamlı olduğu tespit edilmiştir (p=0,046, Odds oranı=0,203, Güven aralığı=0,030-1,231). Kullanılan ilaçların uyku durumu üzerine olan etkisinin çoklu regresyon analizi ile değerlendirilmesinde, antipsikotik ilaç kullananlarda uyku bozukluğunun devam ettiği bulunmuştur (p=0,045, Odds oranı=0,072, Güven aralığı=0,006-0,947).

Sonuçlar: Çalışmamız demans hastalarında galantamin'i n donepezil'e göre uyku bozukluğunu tekli lojistik regresyon analizinde anlamlı düzeyde iyileştirdiğini göstermiştir. Çoklu lojistik regresyon analizinde bu olumlu etkinin ortadan kalkmasının antipsikotik ilaç kullanımına bağlı olabileceği düşünülmüştür. Yeni teşhis edilmiş demans hastalarında özellikle uyku bozukluğu olanlarda, ilaç seçiminde bu durum yararlı olabilecek gibi görünmektedir. Aynı hastalarda davranış bozukluğu için antipsikotik ilaçları kullanırken uyku bozukluğuna yönelik dikkatli takip gerekebileceği kanaatindeyiz.
Analysis of the effects of galantamine and donepezil on sleep disturbances in patients with dementia
Objective: Sleep disturbances occur in various forms of dementia. In this study, the aim was to investigate the effects of galantamine and donepezil on sleep disturbances in patients with dementia.

Method: Subjects, who were admitted to a geriatric outpatient clinic between January 2008 and December 2010, were enrolled in the study. Subjects, who were started on anti-dementia drugs, were assessed. Thirty-eight dementia patients (27 female, 11 male) having sleep disturbances in the beginning were included in the study. The dementia patients were treated with galantamine (n=22) or donepezil (n=16) according to the clinician's opinion. To detect sleep disturbances previously the same prepared questions were directed to all of the subjects and/or their caregivers and the responses were evaluated at baseline and after 24 weeks.

Results: There was no difference in descriptive characteristics among the groups (p>0.05, for all comparisons). When the changes in test scores aimed at evaluating cognition at the baseline and at week 24 were compared between the two treatment groups, there was no significant difference (p>0.05, for all comparisons). Using a univariate logistic regression analysis, it was found that galantamine had a 5 times more favorable effect on sleep disturbances than donepezil and that this difference was significant (p=0.046, Odds ratio=0.203, Confidence interval=0.030-1.231). When the effects of drugs on sleep conditions were evaluated in multiple regression analysis, it was found that sleep disturbances continued in subjects using anti-psychotic drugs (p=0.045, Odds ratio=0.072, Confidence interval=0.006-0.947).

Conclusions: Based on our results, galantamine use improved sleep disturbances significantly more than donepezil in dementia patients in univariate logistic regression analysis. The disappearance of this helpful effect in multiple logistic regression analysis may be related to anti-psyhotic drug use. Consideration of our findings when choosing medications for newly diagnosed dementia patients, especially for those with sleep disturbance, may be beneficial. In addition careful follow-up may be needed to assess sleep disturbances in dementia patients when anti-psychotic drugs are being used.
