Overview
The sense of smell, also known as olfaction, is the ability to perceive and distinguish different odors. The sense of smell is closely connected to the brain and plays a significant role in many aspects of daily life, including our sense of taste, memory, and emotions. Anosmia is the inability to perceive odor or a decreased ability to perceive odor. It can be caused by various factors such as head injury, aging, chronic conditions, exposure to hazardous substances, and viral infections like COVID-19.
