ΟΣΦΡΗΣΗ, ΠΡΟΓΝΩΣΗ ΘΑΝΑΤΟΥ
Οι ηλικιωμένοι που είναι πια ανίκανοι να ξεχωρίσουν μυρωδιές, αντιμετωπίζουν αυξημένο κίνδυνο θανάτου μέσα στην επόμενη πενταετία, σύμφωνα με μια νέα αμερικανική επιστημονική έρευνα. Η μελέτη δείχνει για πρώτη φορά ότι η απώλεια της αίσθησης όσφρησης μπορεί να αποτελεί έναν αρκετά αξιόπιστο προγνωστικό δείκτη πρόωρης θνησιμότητας. Η ανακάλυψη αυτή μπορεί μελλοντικά να οδηγήσει στη δημιουργία ενός νέου οσφρητικού διαγνωστικού τεστ.
 
Οι ερευνητές, με επικεφαλής τον αναπληρωτή καθηγητή χειρουργικής του Ιατρικού Κέντρου του Πανεπιστημίου του Σικάγο Τζαγιάντ Πίντο, που έκαναν τη σχετική δημοσίευση στο περιοδικό"PLoS One", μελέτησαν στοιχεία από ένα αντιπροσωπευτικό δείγμα 3.000 ατόμων ηλικίας 57 έως 85 ετών.
 
Η μελέτη έγινε σε δύο στάδια. Στο πρώτο, οι συμμετέχοντες κλήθηκαν να αναγνωρίσουν διάφορες μυρωδιές (μέντας, ψαριού, πορτοκαλιού, τριαντάφυλλου και δέρματος). Στο δεύτερο στάδιο, μετά από μια πενταετία, οι ερευνητές έλεγξαν ποιοί συμμετέχοντες είχαν στο μεταξύ πεθάνει (ήσαν 430 ή το 12,5%) και συσχέτισαν τους θανάτους με την ικανότητα όσφρησης προ ετών.
Η στατιστική ανάλυση έδειξε ότι μέσα στην πενταετία που είχε μεσολαβήσει, πέθανε το 39%όσων είχαν αποτύχει στο τεστ όσφρησης, το 19% όσων τα είχαν πάει μέτρια στη δοκιμασία και μόνο το 10% όσων είχαν τις καλύτερες επιδόσεις «μύτης». Με άλλα λόγια, όσο καλύτερα μυρίζει κανείς, τόσο λιγότερο κινδυνεύει να πεθάνει πρόωρα.
 
Η μελέτη έδειξε ότι αν κανείς βρίσκεται σε ομάδα υψηλού κινδύνου για κάποιο λόγο υγείας και παράλληλα η όσφρησή του δεν δουλεύει καθόλου καλά, τότε ο κίνδυνος πρόωρου θανάτου είναι υπερδιπλάσιος. Οι επιστήμονες δεν έχουν καταλάβει ακόμη πώς και γιατί η όσφρηση σχετίζεται με τη θνησιμότητα. Είναι όμως αξιοσημείωτο, όπως είπαν, ότι η δυσλειτουργία της όσφρησης αποτελεί καλύτερο δείκτη πρόγνωσης για πρόωρη θνησιμότητα απ’ ότι μια διάγνωση καρδιοπάθειας, καρκίνου ή πνευμονοπάθειας
