7. Sensory disturbances
There are many sensory disturbances associated with brain tumors, and they depend on the site of the tumor and its growth. It may cause visual changes which will be addressed further and even changes in the perception of smell when they are located in the frontal lobe. Patients may also have a gradual loss of perception in one side or section of the body when the tumor is located in the postcentral gyrus or near this area. In the postcentral gyrus, our brain receives and interprets the sensation of pressure and touch, and we will no longer have these sensory perceptions when a tumor is compressing the area.
