The life-threatening ramifications of sustaining a head injury can mean that secondary symptoms - such as loss of smell - are often overlooked in the early weeks of recovery. While it may not seem like a significant condition, losing your sense of smell and taste can be quite distressing.
How your smell and taste are affected depends on the nature of the injury and the area of the brain affected. The areas of the brain that primarily control our sense of smell are the orbitofrontal cortex (behind and above our eyes), the insula (beneath our ears), and the piriform cortex (located between the first two).
Other than these, there are some smaller areas of the brain that are also involved in controlling our sense of smell, called olfactory regions. If the bone directly behind the nose - known as the cribriform plate - is significantly damaged, the olfactory nerves that run to the nose could be damaged or severed, leading to a loss of smell.
Your doctor will be able to discuss the nature of your partiular injury, and whether you can expect to recover smell and taste.
Treating the loss of taste and smell after suffering a traumatic brain injury (TBI) depends upon the nature and extent of the injuries sustained, as well as which variations of the disorders you are experiencing.
Where there is no obvious reason for smell to be permanently affected, research demonstrates that starting smell training as early as possible best supports recovery.
Bad or distorted senses of taste - known as parageusia and dysgeusia - may be treated with medications like Gabapentin.
Life without smell and taste - even temporarily - has additional challenges. AbScent provides information, practial advice and facilitates connections with others experiencing the same thing.
