Genes Identified for Alzheimer’s Disease Risk

Scientists have identified five genes which raise the risk of Alzheimer's disease. It would be a breakthrough for the effective treatment of the disease. International team of scientists from the US and Britain said that with the discovery of the five new genes, a total of 10 genes are now known to be linked with the most common form of dementia. 

Scientists carried out a research under which they analysed the DNA of nearly 60000 people with and without disease. The research would provide scientists clues as to how the disease might develop. The identification of genes could lead to the development of drug treatments.
Alzheimer’s disease is the most common form of Dementia. Alzheimer's dementia first destroys cell in brain and leads to mental disorder. Dementia means irrationality. It occurs after the age of 60's. It doubles for every 5 years increase in age. The most common symptom in Alzheimer's dementia is confusion. Slowly progressing destruction of nerve cells in brain leads to Alzheimer's dementia.

Problems that happen due to the Alzheimer's are problem in decision-making, in thinking, language problems, personality-disorder, abstract thinking and loss of initiative.

Alzheimer's disease is the most common cause of dementia. There are three common forms of dementia. They are Alzheimer's disease, lewy body dementia and vascular dementia.
