Loss of Smell may lead to early onset of Alzheimer’s Disease

There are a number of people in the world who experience loss of smell or smell disorder in their life period. While there are other people who apart from smell disorder even encounter loss of taste. But life is all about smell and taste. We enjoy our food and can tell the host the food is tasty. Smelling power alert human beings when a smoke emanates or in the case of gas leak. Smell and taste are an eternal part of human beings. In the absence of it life becomes tasteless. In medical terms loss of sense is known as hyposmia and total loss of it is called anosmia. In a recent study published in the Journal of Neuroscience dated January 13, 2010 the loss of smell disorder has been related to Alzheimer’s disease (AD).

The study was carried on the genetically engineered mice at NYU Langone Medical Center revealed that olfactory dysfunction – a common symptom of Alzheimer could be considered as an early warning tool for the disease. During the course of the study these mice developed amyloids in their brains, just akin to humans. In the case of Alzheimer disease amyloid pathology starts in the region of brain, which is responsible for smell, just above the nose. The article disclosed that the symptoms of this disease could be seen early in life, this novel olfactory would further help in the early detection of this disease, before the attrition of the brain. Noted co-author of the project, Daniel W. Wesson, PhD, of the NYU School of Medicine and the Nathan S. Kline Institute for Psychiatric Research in Orangeburg, New York said, this is an astonishing finding because just like a brain scan, a laboratory designed olfactory test would be an inexpensive way to detect Alzheimer at an early stage.

However, not all cases could be linked to the loss of smell with the Alzheimer, as there are various reasons for the loss of sense of smell like, after effect of different medications like that pertaining to allergy, nutritional deficiency, metabolic disorder or sinus or respiratory problem which occurs due to polyps of sinus disease. Sometimes head injury could result in an instant loss of smell which would be permanent in nature. At times due to cold weather there could be a temporary loss of smell. The nasal obstructions and sinus polyps could also be the reason behind temporary loss of smell and after sometime people would get back their loss of smell.

The loss of smell in a person could be gauged when a person complains about the food being tasteless. A person suffering from cold and flu could also complain about the loss of smell and taste for weeks. There are also herbal remedies available for AD like Clematis, Mugwort, Euphobia, fenugreek, Horse Radish etc.

    It was first described by German psychiatrist and neuropathologist Alois Alzheimer in 1906 and was named after him.

    Herbs Pro has been our favorite website to let ourselves be consciously updated with almost any sort of health-related articles. This article reminded me of my late grandmother who was previously diagnosed with Alzheimer’s disease. Her condition was milder compared to the others, however, when the condition strikes, she literally forgets almost everything. I highly agree with this article stating that a loss of smell can indicate the onset of this condition. Once when we were having dinner, my mom prepared roasted chicken. Naturally, the chicken would smell so delectable to our senses! Surprisingly though, grandma found it lightly marinated accompanied with a faint smell. This took our attention but just mistook it for her flu. I hope this could be a lesson to others as well.

    I have read a lot of blogs before, but this one caught my attention the most. Alzheimer disease was discussed, and statistics have proven that a lot of people have a greater chance of having this. My father was diagnosed with this condition, it was really hard for our family to see our father suffering from this. We all do our best to show to our father how much we love him. Thanks to this blog we can still support our father’s mental health by learning a lot of pointers. My advice for other people out there who have the same experience as I do is to have patience and trust that our loved one can recover from this disease.

    I am laughing at myself now for thinking that the loss of smell – and taste – can only be experienced when we have colds. I didn’t know that it can be caused by different factors like medication and head injury. Alzheimer is another story though. I just know that it is a neurological disorder which causes memory loss and cognitive decline. It didn’t even occur to me that this would relate with the disorders of the nervous system which, of course, involves our senses. I am ashamed for having forgotten all these science related topics. Diagnosis for Alzheimer or any brain related disorders are really expensive. The olfactory test would be a better option especially to the older people who are more cautious with their health.
