Should improve: If this was a concussion and there was no fracture of the cribiform plate, the loss of smell and taste is not uncommon nor is it unusual. This has a good chance of improving over time. It may take 6-12 weeks. ...Read more

B12 anyway: Olfactory nerves can be sheared with any head injury as they are vulnerable with many exits through the bone above the nose. It may take 6- 8 months to recover some smell but possibie it may not return. Good book recommended: “navigating smell and taste disorders” (demos health). An ENT doctor may give steroids to reduce swelling in the area. Consider seeing a cranial- trained osteopath. ...Read more

I've lost my sense of small after a concussion. Will my sense of smell ever return?

I've lost my sense of small after a concussion. Will my sense of smell ever return?

Maybe: Traumatic injury to the head may put tension on, and in some cases completely disrupt, the nerves that convey the sense of smell. These nerves are uniquely vulnerable because they pass directly through a piece of bone called the cribiform plate. Depending on how injured the olfactory nerve is, the sense of smell may gradually return or may never return. ...Read more

I had a concussion and my sense of smell has become all distorted due to it. When will i get it back to normal?

It may not: Loss of smell following head injury is worrisome for breakage of the olfactory fibers going through the cribriform plate. This damage is usually irreversible. ...Read more

Concussion: Loss of smell is fairly common after concussions. Often there is a fracture through the cribiform plate (which can be hard to visualize on a CT scan of the brain) or shearing of the tethered olfactory tract. Generally the sense of smell remains diminished and likely will not improve after six months from the time of the head trauma. ...Read more

I : I am very concerned about your symptoms. I would like you to see a neurologist and have a complete evaluation of your symptoms. Your symptoms sound somwhat like a concussion, but the duration is very concerning and you need a full neurological evaluation. If you are having this severe of symptoms then you should not be participating in any type of sports until you are cleared. In addition, you should see your ENT doctor again to re-evaluate your persistent injury. But seeing the neurologist is most important at this time. If you have worsening headache, visual changes, vomiting, weakness or numbness then you will have to be seen as an emergency. ...Read more

Might concussions cause memory loss?

Might concussions cause memory loss?

Memory loss: Concussion causes 2 types of amnesia. Retrograde amnesia means a loss if information from the injury back in time. The most likely loss is recently learned info. You may get the info back. A prograde amnesia is amnesia from the injury forward in time. You are not laying down new memory traces at that time. It is unlikely you will regain memory loss from prograde amnesia. ...Read more

CONCUSSION: To concus means 'to shake violently'; which is what happens to the brain when the head or trunk is violently impacted. This violent event causes brain injury at the cellular level, which is why symptoms and recovery are vary from person to person. The key to recovery is close follow up with a provider knowledgeable in the concussion who'll monitor symptoms & neurocognitive test results. ...Read more

My son has a severe concussion and short term memory loss, how long will this last?

Varies: It can last a month to months. I would highly recommend seeing an acupuncturist/chinese medicine practitioner. I have had more rapid recovery in patients by adding these treatments. He may also have headaches for a couple months and mood swings from the injury. He needs to stay hydrated as well and it is ok if he needs school adjustment as he will not perform well until he is better. ...Read more
