Alzheimer’s disease is a neurodegenerative disease which in its most common form occurs in persons over the age of 65 and for about 60% of the cases dementia is responsible. Alzheimer’s disease symptoms are characterized by progressive deterioration of cognitive performance and it decreases daily activities and there are some neuropsychological and behavioral symptoms too.
To date the cause of Alzheimer’s disease is not fully understood. ApoE is a kind of gene variant which has been proved to create risk of developing Alzheimer’s disease. Three genes have been found for triggering the early onset subtypes in addition to this.
Their contribution in developing of Alzheimer’s is about 30%. Alzheimer’s disease cannot be cured yet. We cannot find so much positive effects of the currently approved drugs so far. They cannot slow down the progression of the disease. A consensus paper on the subject of Alzheimer’s disease treatments got published by American Association for Geriatric Psychiatry in 2006.
