What medication causes loss of smell?
Intranasal zinc products, decongestant nose sprays, and certain oral drugs, such as nifedipine and phenothiazines, are examples of drugs that may cause permanent loss of smell. Anosmia may also result from diseases of the nerve pathways that transmit smells to the brain.

What are the five safety smells that are lost with dementia?
Losing the ability to smell peppermint, fish, orange, rose and leather could be an accurate early warning sign of dementia, according to a new study. The ability of nearly 3,000 people aged 57 to 85 to detect these five odours was tested by scientists.

What is your weakest sense?
Taste is a sensory function of the central nervous system, and is considered the weakest sense in the human body.
What part of the brain controls the smell?
Odors in the Brain One of these areas is the piriform cortex, a collection of neurons located just behind the olfactory bulb that works to identify the smell. Smell information also goes to the thalamus, a structure that serves as a relay station for all of the sensory information coming into the brain.
How do you cure loss of smell?
