Smell and Taste Disorders in Primary Care.

Area of Science:

• Otolaryngology
• Neurology
• Geriatrics

Background:

• Prevalence of smell and taste disorders increases with age, affecting quality of life and safety.
• These sensory dysfunctions can be early indicators of neurodegenerative diseases like dementia and Parkinson's.
• Patients are often unaware of their condition, highlighting the need for screening.

Purpose of the Study:

• To review the causes, diagnosis, and management of smell and taste disorders.
• To emphasize the importance of recognizing these disorders as potential early signs of serious underlying conditions.
• To provide guidance on appropriate diagnostic evaluations and treatment strategies.

Main Methods:

• Review of existing literature on smell and taste dysfunction.
• Discussion of diagnostic approaches including physical examination, nasal endoscopy, and imaging (CT, MRI).
• Consideration of olfactory testing for specific patient groups.

Main Results:

• Most disorders stem from sinonasal disease, but other causes include smoking, medications, head trauma, and neurodegenerative diseases.
• While some cases resolve with treatment of reversible causes, improvement is less likely in cases related to trauma, aging, or neurodegeneration.
• Olfactory training shows promise as a self-administered therapy to improve olfactory function.

Conclusions:

• Early identification and management of smell and taste disorders are vital due to their impact on quality of life and association with significant health risks.
• Physicians should consider these disorders in differential diagnoses, especially in older adults.
• Patients should be advised on safety measures, such as ensuring functional alarms and adhering to food expiration dates.
