Platelet-rich plasma for smell loss from aging or head injury
Part of Brain & nervous system clinical trials.
This study tests if a treatment made from your own blood (platelet-rich plasma) can improve smell loss caused by aging or head injury. The goal is to see if it's safe and if it helps people regain some sense of smell.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older.
- You have had a reduced sense of smell for more than 6 months.
- The smell loss is due to aging or a head injury, not a tumor or other cause.
- A smell test (called Sniffin' Sticks) confirms your smell is below a certain level.
- You had an MRI in the last 6 months that showed no tumor or central nervous system cause.
- You are not taking blood thinners or high-dose anti-inflammatory drugs on a daily basis.

This trial tests whether injecting a concentrated solution from your own blood, called platelet-rich plasma (PRP), into the nose can help restore the sense of smell in people with smell dysfunction. It may offer a new treatment option for those who haven't improved with other therapies.
This study tests whether acupuncture can help people who lost their sense of smell after a head injury. If you are between 18 and 60 and have not had certain treatments recently, you may be able to join.
This study tests a new way of doing smell training to help people whose sense of smell has not recovered after a viral illness. It may help you smell things better again.
This study is looking at how the brain processes smells in people with chronic sinusitis and nasal polyps who have a reduced sense of smell. It will compare brain images (MRI) of patients who are starting biologic treatment and those who are not, to understand how these medications might affect the brain.
This study looks at why sense of smell changes as people get older. By participating, you may help researchers better understand smell loss in aging, which could lead to earlier detection of health issues.
This trial tests whether a treatment made from your own blood (platelet-rich plasma) can help restore your sense of smell after an infection, and whether adding insulin makes it work better. You’ll receive the treatment inside your nose, and the study will compare the two options.
