Diagnosing<unk>  precisely can be difficult due to the variety of causes and symptoms. Often, patients may be unsure whether or not they are having issues with smell or taste specifically. It is important to identify whether the distortion applies to an inhaled odorant or if an odor exists without the stimulus. Distortion of an odorant is presented in two types: when the stimuli are different from what one remembers, and when everything has a similar smell. A clinical history can also help determine what kind of<unk>  one has, as events such as respiratory infection and head trauma are usually indications of parosmia. Phantosmia often occurs spontaneously. Unfortunately, there are no wholly accurate diagnostic tests or methods for<unk> .; evaluation must be done through questionnaires and medical history.
