Abstract
Objective:
In this review, we
will mainly focus on the the general properties of Alzheimer’s disease and will
also mention the biological agents that are suggested to play roles in the
pathophysiology of Alzeheimer’s disease and the studies performed on these
agents.
Result
and Discussion: The
increase in elderly population due to the increasing population worldwide has
led to an increase in the prevalance of Alzheimer’s disease. In the last years,
scientific studies on different types of dementia and particularly on
Alzheimer’s disease have accelerated. It is known that this disease has
multi-genetic grounds. However, exposure to several biological agents are also
suggested to play roles in the pathophysiology of Alzheimer’s disease. There
are studies in literature suggesting that infections like Herpes simplex virus
tip-1 (HSV-1), human immunodeficiency virus type 1 (HIV-1), Helicobacter pylori
and endogenous prion poteins can contribute to the development of this disease.
On the other hand, there are studies suggesting that diseases like diabetes can
expedite the development of Alzheimer’ss disease.
