Symptoms based on tumour location in the brain
Symptoms of a brain tumour can vary depending on the tumour's location.
The brain is divided into two halves called the right and left hemispheres. The brain can also be divided into four areas known as lobes (frontal, temporal, parietal and occipital) plus two other important areas called the brain stem and the cerebellum.
The presence of a brain tumour can cause damage to healthy brain tissue, disrupting the normal function of that area.
Remember that many of the symptoms due to raised intracranial pressure (ICP) can be caused by other medical conditions. So if you are experiencing these symptoms, it does not necessarily mean you have a brain tumour.
A brain tumour located in the frontal lobe may cause difficulty with:
- concentrating or focusing your attention on something
- communication skills and language production
- controlling emotions and behaviour
- executive functions (making decisions, solving problems, planning and organising)
- learning and remembering new information
- lack of inhibition (making inappropriate comments during conversation or laughing in inappropriate situations)
- social cognition, impulse control and sexual behaviour
- weakness on the opposite side of the body from the tumour
- loss of smell.
A brain tumour located in the parietal lobe may cause difficulty with:
- bringing together information from your different senses (touch, vision, hearing, smell, taste) and making sense of it
- recognising faces or objects
- co-ordinating movements
- spatial awareness (judging distances and hand-eye co-ordination)
- speaking, understanding words, writing and reading
- numbness on the opposite side of the body from the tumour.
A brain tumour located in the cerebellum may cause:
- difficulty with balance
- loss of co-ordination
- difficulty walking and speaking
- difficulty using executive functions (making decisions, solving problems, planning and organising)
- flickering of the eyes
- stiff neck
- problems with dexterity (skills in using your hands).
