Demans, düşünme ve hatırlama yeteneğinde uzun süreli ve kademeli olarak azalmaya neden olan bir hastalıktır. Alzheimer hastalığı, yaşlılardaki demansın en sık nedenidir ve bilişsel işlevlerin genel kaybı ve ölümün izlendiği, genellikle yavaş ilerleyen, kısa erimli bellek kaybı ile karakterize kronik bir nörodejeneratif hastalıktır. Hastalık ilerledikçe ruh hâli değişimleri, motivasyon kaybı, konuşma işlevlerinde bozulma, özbakım yapamama ve davranış sorunları ortaya çıkabilmektedir. Dünya genelinde yaşlı nüfus oranının giderek artması, yaşam tarzında doğallıktan uzaklaşma ve kronik hastalıkların artması Alzheimer hastalığı görülme sıklığını artırmaktadır. Bu nedenle, Alzheimer hastalığına yol açması olası faktörlerin bilinmesi, hastalığa erken dönemde tanı konması ve tedaviye mümkün olduğunca erken başlanması açısından önemlidir. Kimyasal ajan olarak çevresel kirleticilerin nöropatolojik durumları indükleyerek Alzheimer hastalığına yol açabileceği belirtilmektedir. Bu konuda toksik metaller, endüstriyel kirleticiler, hava kirleticileri, pestisitler, antimikrobiyal ajanlar konularında farklı araştırma grupları tarafından, gerek in vivo gerekse in vitro birçok farklı araştırma yapılmıştır. Ayrıca, büyük cerrahi girişimler sırasında kullanılan genel anestezikler, yaşlı hastalarda postoperatif kognitif disfonksiyon komplikasyonuna yol açabilmektedir. Bu ilaçlar sinir dokusunda inflamasyona neden olabilmektedir, bu durumda sık cerrahi girişimde bulunulan hastalarda seneler sonra Alzheimer hastalığı ortaya çıkabileceği belirtilmektedir. Bu çalışmada, Alzheimer hastalığının genel özelliklerinden bahsedilmesi; bu hastalığın patofizyolojinde rol oynayabileceği bildirilen kimyasal ajanlardan ve bu konularda yapılmış çalışmalardan söz edilmesi amaçlanmıştır.

Dementhia is a disease that causes long and gradual decreases in the thinking and remembering Alzheimer's disease is the main cause of ementhia in elderly. It is mainly a longlasting neurodegenerative condition characterized with short staged memory loss, a general loss of cognitive functions and finally death. As the disease proceeds, mood changes, motivation loss, deterioration of speech, self-care and behavior problems can arise. Throughout the world, increase in incidence of Alzheimer's disease are suggested to be caused by ageing of population, widespread chronical diseases and divergence of modern lifestyle from the nature. Therefore, it is important to know these factors affecting the incidence of Alzheimer's disease and it plays a vital role in early diagnosis and medical treatment. As chemical agents, environmental pollutants might trigger Alzheimer's disease by inducing the neuropathological conditions. Many research -both in vivo and in vitro- were conducted on air pollutants, toxic metals, antimicrobial agents and industrial pollutants. In addition, the general anesthetics that are used during vital surgical operations to old patients may cause post-operative cognitive-disfunction complications. These anesthetics can also result in inflamation in neural tissue. It has been stated that Alzheimer's disease might ocur in years in patients that had frequent surgical operations. In this review, we will discuss the general characteristics of the Alzheimer's disease; the chemical agents that plays role on the pato-physiology of Alzheimer's disease and we will give a general overview of previous research on stuides conducted on chemicals agents as a cause of Alzheimer's disease.
