It can be partially lost, but I'm not sure if fully. I would imagine so though.
A ferret could possibly lose their sense of smell from an illness.
No, you do not lose your sense of smell during sleep. Your sense of smell continues to function while you are asleep, although it may not be as active as when you are awake.
Smell
When you lose your sense of smell you begin to lose taste too. This happens because a large portion of your taste comes from smell.
The sense of smell is generally lost between ages 70-80. Also, it must be noted that it will be lost but not by some.
It depends on which part of the brain was injured - not all people lose their sense of smell. If the part of the brain that controls that sense is injured, then you will lose the ability because the brain cells are damaged and don't work to report smells like they used to.
nobody knows
Yes
Yes, there are some people who are born without a sense of smell, known as anosmia. This condition can be due to a variety of factors such as genetics or nerve damage. Additionally, some individuals may lose their sense of smell later in life due to factors such as head trauma or certain medical conditions.
No. That doesn't make any sense, does it? While we sleep a lot of our sensory information goes to our dreams, it takes a strong jolt to wake us up, whether it be a smell, bright flash, loud sound, etc. If that were the case, then smelling salts wouldn't wake people up, either.
alzheimers
Think about when you get a stuffy nose. When you lose your sense of smell it impairs your sense of taste.
