Researchers used a simple and affordable smell test to determine Alzheimer's risk. Besides the inability to detect the scents of peppermint, orange, fish, rose and leather, here are other early warning signs of dementia.

Peppermint is one of five specific scents researchers used to identify olfactory damage among their participants. Those unable to smell the five scents were more than twice as likely to be diagnosed with dementia within five years.

Testing a patient’s ability to identify objects using odor could help detect Alzheimer’s disease earlier. Researchers have found the link between the olfactory sense and Alzheimer’s progression.

A new study by UC Berkeley researchers suggests that a person's sense of smell can affect how the body will deal with calories. The results show a relationship between the olfactory system and brain regions known to control metabolism.

The human sense of smell has recently been shown to be better than previously thought. Looking back, how did our ancestors’ sense of smell evolve to the way it is today?

It is a popular belief that the human olfactory sense is inferior to that of other mammals. A new research traces the history of this myth and proves this false.

Could fading sense of smell mean death is closer? A Swedish study suggests that people in their middle age or older suffering from impaired sense of smell are more likely to die within 10 years.

A study found that dodos had a heightened sense of smell that helped them to scout for food on land. Previously thought of as stupid, dodos were actually just naïve, a trait that probably contributed to their early demise.

We experience the world through our five senses, but neuroscientist Don Katz believes that we may actually have only one, all-encompassing sense: the chemosensory system. Katz has gathered evidence connecting the codependency between the sense of smell and taste.

Losing the sense of smell may be an early indicator for dementia and other neurodegenerative diseases. Researchers found that the chances of developing these brain diseases increase as the ability to detect scents decreases.

The ability of a woman in Scotland to detect the scent of Parkinson's disease in her husband has led researchers to investigate the potential of using the sense of smell to diagnose malignancies in patients. A study is now being conducted to find out if dogs can be used to identify the odor of prostate cancer in samples of human urine.

The nose knows; every person has a sense of smell that's theirs and unique to them, a study finds. Finding could have applications in medicine, and a person's "olfactory fingerprint" could even be a security aid, researchers suggest.

Women not only like things that smell good but they can also smell better than men because their brains are made that way, says a new study.

Two researchers found that chemical compounds in smells have an opposing set of odor compounds that cancel each other out, creating a 'white noise' for the nose.

Anosmia, or the inability to decipher common smells, is one of the strongest predictors of death -- far more accurate than the existence of cancer, heart disease or lung problems, a new study suggests. Older adults with olfactory dysfunction are three times more likely to die in five years.
