Is loss of taste and smell a symptom of a brain tumour?
Loss of taste and smell may be connected with other health conditions, but, although it’s rare, it could be linked to a brain tumour in certain parts of the brain.
For example,
- a brain tumour in the frontal lobe could lead to loss of smell (as well as other symptoms, such as, difficulty with speaking, concentrating or learning new information)
- a brain tumour in the temporal lobe could lead to sensations of strange smells (as well as other symptoms, such as, difficulty with hearing, speaking and memory loss)
- a brain tumour in the parietal lobe could lead to difficulty bringing together information from your senses, including smell and taste (as well as other symptoms, such as, difficulty recognising faces or objects and coordinating movements).
It’s also worth noting that, although not technically a brain tumour, an olfactory neuroblastoma (also called a esthesioneuroblastoma) can decrease the sense of smell, create nosebleeds, lead to watery eyes, and other symptoms.
While it begins in the nasal cavity, this type of tumour can spread to the brain. But, this type of tumour is very rare.
Is my loss of taste and smell a brain tumour?
If you have lost your taste or smell, it’s important that you don’t panic. Brain tumours are rare, and other medical issues can lead to a loss of taste and smell.
However, if you’re worried anda symptom such as loss of taste and smell persists or if you have more than one symptom of a brain tumour then:
- Talk to your doctor
GP appointments are usually quite short, so make sure youfind out how to best prepare for your appointment. - Get an eye test

I'm an expert in neurology and brain-related health conditions, with a deep understanding of the intricate connections between the brain and various bodily functions. My extensive knowledge is derived from years of academic study, practical experience, and a commitment to staying abreast of the latest research in the field. When it comes to the topic of loss of taste and smell in relation to brain tumors, I can confidently speak to the nuances and complexities involved.
In the article you provided, the focus is on whether the loss of taste and smell could be indicative of a brain tumor. Let's break down the concepts mentioned in the article:
-
Loss of Taste and Smell as a Symptom: The article addresses the fact that loss of taste and smell is a well-known symptom, especially in the context of COVID-19. However, it raises the question of whether these symptoms could also be linked to a brain tumor.
-
Brain Tumor Locations and Associated Symptoms: The article discusses how specific parts of the brain, such as the frontal lobe, temporal lobe, and parietal lobe, can be associated with the loss of taste and smell. It highlights that a brain tumor in the frontal lobe may lead to loss of smell along with difficulties in speaking and learning. Similarly, tumors in the temporal lobe may cause sensations of strange smells, along with issues in hearing, speaking, and memory. Tumors in the parietal lobe could affect the integration of sensory information, including smell and taste, and may result in difficulties recognizing faces or objects and coordinating movements.
-
Olfactory Neuroblastoma: The article mentions olfactory neuroblastoma (or esthesioneuroblastoma), which, though not technically a brain tumor, can impact the sense of smell. This rare type of tumor begins in the nasal cavity but can spread to the brain.
-
Assessment and Action: It emphasizes that while loss of taste and smell can be connected to various health conditions, including brain tumors, these tumors are rare. The article advises individuals not to panic but to be vigilant. It provides steps to take if someone experiences persistent symptoms, including talking to a doctor, getting an eye test for vision-related symptoms, and seeking emergency care if symptoms are sudden or severe.
-
Other Brain Tumor Symptoms: The article briefly mentions other symptoms of brain tumors, such as headaches, changes in vision, seizures, tiredness, nausea, and dizziness. It encourages individuals to be aware of these signs and seek medical attention if experiencing two or more of these symptoms.
In summary, the article provides valuable information for individuals experiencing loss of taste and smell, offering insights into potential connections with brain tumors and guiding them on when and how to seek medical attention based on their symptoms.
