Can a brain tumor cause loss of taste and smell?

Yes, brain tumors can cause loss of taste and smell. Brain tumors can affect the nerves and structures in the brain that are responsible for these senses. Tumors in the frontal lobe, temporal lobe, or pituitary gland can all potentially lead to a loss of taste or smell. Additionally, pressure on the olfactory bulb or tract can also cause a loss of smell. In some cases, the loss of taste and smell may be temporary and resolve after treatment, while in other cases it may be permanent.
