<P> Amiodarone is a drug used in the treatment of arrhythmias of the heart . A clinical study performed demonstrated that the use of this drug induced anosmia in some patients . Although rare, there was a case in which a 66 - year - old male was treated with Amiodarone for ventricular tachycardia . After the use of the drug he began experiencing olfactory disturbance, however after decreasing the dosage of Amiodarone, the severity of the anosmia decreased accordingly hence correlating the use of Amiodarone to the development of anosmia . </P> <Ul> <Li> Upper respiratory tract infection (e.g., sinusitis or the common cold) </Li> <Li> Nasal polyps </Li> <Li> Idiopathic hypogonadotropic hypogonadism </Li> <Li> Hypothyroidism </Li> <Li> Head trauma, damage to the ethmoid bone </Li> <Li> Dementia with Lewy bodies </Li> <Li> Tumors of the frontal lobe </Li> <Li> Antibiotics </Li> <Li> Fibromyalgia </Li> <Li> Multiple sclerosis </Li> <Li> Hypoglycaemia </Li> <Li> Diabetes </Li> <Li> Asthma or Allergy </Li> <Li> Hayfever </Li> <Li> Chronic obstructive pulmonary disease (COPD) </Li> <Li> Long term alcoholism </Li> <Li> Cushing's syndrome </Li> <Li> Exposure to a chemical that burns the inside of the nose </Li> <Li> Stroke </Li> <Li> Epilepsy </Li> <Li> Radiation therapy to the head and neck </Li> <Li> Liver or kidney disease </Li> <Li> Parkinson's disease </Li> <Li> Alzheimer's disease </Li> <Li> Toxins (especially acrylates, methacrylates and cadmium) </Li> <Li> Old age </Li> <Li> Kallmann syndrome </Li> <Li> Primary ciliary dyskinesia </Li> <Li> Post-perfusion syndrome </Li> <Li> Laryngectomy with permanent tracheostomy </Li> <Li> Esthesioneuroblastoma is an exceedingly rare cancerous tumor that originates in or near the olfactory nerve .
