Loss of taste and smell

Although it’s rare, loss of taste and smell can be linked with brain tumours in certain parts of the brain.

Loss of taste and smell is something that’s been spoken about a lot in the last couple of years, as it’s a key symptom of coronavirus (COVID-19) and one that can last for weeks or months in some cases. 

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).

I think I have a brain tumour, what should I do?

Brain tumours are rare, however, if you’re worried and a 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 you find out how to best prepare for your appointment.
  • Get an eye test
    If your symptoms are limited to changes in vision and/or headaches, get your eyes tested by an optician before seeing your GP.
  • Go to A&E
    If the symptoms are sudden or severe, you should go to your emergency department or call 999.
