  1. How long have you had the loss of the sense of smell (anosmia)?

    Why: to determine if acute or chronic. Acute loss of smell would certainly suggest an acute upper respiratory tract infection (URTI). It would also suggest recent exposure to toxic fumes or recent head injury.

  2. Is the loss of smell general, partial or specific?

    Why: e.g. general anosmia is the inability to detect any smells; partial anosmia is the ability to detect some, but not all smells; specific anosmia is the loss of ability to appreciate only one or a very limited number of smells.

  3. Is the loss of smell intermittent or constant?

    Why: If intermittent, may suggest psychomotor epilepsy.

  4. Is it unilateral or bilateral?

    Why: If unilateral must consider an olfactory groove meningioma ( benign tumor of the lining of the brain in the region of the lower surface of the frontal lobe of the brain).

  5. What is the age of the person with the loss of smell?

    Why: It is normal to get a gradual reduction in the sense of smell and taste with aging.

  6. Is it possible that the loss of smell has been present since birth?

    Why: may suggest a congenital cause such as Kallmann's syndrome (hypogonadotrophic hypogonadism) or albinism.

  7. Is there a history of head injury?

    Why: A skull fracture, particularly if it involves the cribriform plate, may interrupt the olfactory nerve and cause loss of smell.

  8. Have you had a recent upper respiratory tract infection?

    Why: may suggest acute upper respiratory tract infection itself or sinusitis as the cause of loss of smell.

  9. Recent exposure to toxic fumes?

    Why: e.g. paints and sprays- may suggest cause of loss of smell.

  10. Has there been an overuse of nasal decongestant sprays?

    Why: may be the cause of the loss of smell.

  11. Past medical history?

    Why: e.g. some endocrine disorders can affect smell such as Cushing's syndrome, hypothyroidism and diabetes mellitus; Parkinson's disease and Alzheimer's disease may be associated with loss of smell.

  12. Past surgical history?

    Why: e.g. may have a loss of smell after pituitary surgery.

  13. Past history of radiation therapy to the head?

    Why: may cause loss of smell.

  14. Medications?

    Why: some medications are known to cause loss of smell such as captopril, penicillamine, antirheumatic medications and antiproliferative medications.

  15. Known allergies?

    Why: e.g. allergies t pollens, moulds, house dust mites, animal fur and some foods may cause allergic rhinitis.

  16. Dietary history?

  21. Facial pain?

    Why: e.g. sphenoidal or ethmoidal sinusitis causes a constant pain behind the eye or behind the nose.

  22. Memory loss?

    Why: may suggest an olfactory groove meningioma ( benign tumor of the lining of the brain in the region of the lower surface of the frontal lobe of the brain) or a tumor of the parietal lobe of the brain. Some causes of dementia such as Parkinson's disease and Alzheimer's disease may also cause loss of smell.

  23. Nasal discharge?

    Why: e.g. a pus-like nasal discharge may suggest acute or chronic sinusitis; a watery nasal discharge may suggest upper respiratory tract infection or rhinitis; a bloody nasal discharge may suggest nasopharyngeal cancer.
