Alzheimer’s disease is the silent killer disease in the world and has affected millions of people globally. There is no appropriate treatment available to treat the disease and we can just determine the risk factors and the symptoms of the disease. Some of the early signs of the disease are weak memorizing ability, mood swings, language disorders and neurodegenerative diseases.
According to the new study conducted by the researchers from McGill University Canada, the poor sense of smell or complete loss of smell is one of the crucial factors which indicated the risk of Alzheimer’s disease. Although the Alzheimer’s disease mostly affects the elderly group, the signs, and symptoms of the disease begin quite before. The people who cannot determine different smells like the smell of lemon, kerosene may be at the risk of suffering from this condition.
The neurodegeneration or damage to brain starts quite earlier almost 20 years before. This new study has stated that odor test or the sense of smell may hold true for determining whether the individual is at the risk of Alzheimer’s disease or not. Although this test cannot completely eradicate the risk of dementia, the onset of symptoms and the disease can be delayed to reduce its severe impacts.
For the study, the researcher’s studies around 300 elderly people who have a family history of Alzheimer’s disease and them conducted the odor test on them. During this test, the participants were asked to determine the smell of different products like the scent, bubble gum, petrol, lemon, smoke etc.
After the end of the study, it was seen that the individuals who were unable to recognize the smell of different products were the ones suffering from the Alzheimer’s disease. This is the first study to show the how the sense of smell is directly related to the risk of Alzheimer’s disease. Th complete study and its conclusions have been published in the journal Neurology.
