Is it possible to not have a sense of smell?
Yes. People who cannot smell suffer from some form of nasal dysfunction. * Anosmia is the complete loss of the sense of smell. Congential anosmia is rare, but can run in families. Traumatic anosmia can occur due to an injury, and viral anosmia can occur due to an infection. * Hyposmia is the partial loss of the sense of smell. * Parosmia is a distortion of the sense of smell. People with this dysfunction smell one smell and confuse it with another. * Phantosmia is when smells are imagined. * Presbyosmia is the decrease in the sense of smell due to aging.
