Perda de olfacto na terceira idade é mau sinal

E porquê mesmo?

"A healthy sense of smell depends on a continual turnover of cells lining the nose
Losing this function could be an indicator of less regeneration in the body overall 
Researchers from Stockholm followed 1,174 adults aged 40 to 90 for ten years

Pensioners who lose their sense of small are more likely to die within 10 years, according to a new study.

Researchers say the findings suggest measuring older patients’ sense of smell could indicate their overall well-being.

The analysis, of almost 1,800 people, found those who struggled to pick up scents and odours were more likely to die over the next decade.

And the phenomenon was not linked to those with dementia, which has previously been associated with a loss of smell.

(...)
Dr Olofsson said: 'Poor odour identification and poor self reported olfactory function are associated with greater likelihood of future mortality. Dementia does not attenuate the association between olfactory loss and mortality, suggesting olfactory loss might mark deteriorating health, irrespective of dementia.'

Three years ago a study of 3,000 adults found four in ten of those with the poorest sense of smell were dead within five years compared to just one in ten who identified odours correctly."
