Brain tumour side effects and their causes
There are lots of different things that can cause brain tumour side effects. And, if you’d like to understand each of the side effects better, the links above will give you more complete information. But, the list below will give you a brief look at some of the things that cause these side effects.
Sadly, brain tumours can cause changes to someone’s personality. This can be because of where the tumour is in the brain, swelling in the brain, some medical treatments, or possibly the emotional side of being diagnosed.
People with brain tumours might have difficulty remembering things. If this happens, it could be because of the tumour affecting the parts of the brain that deal with memories. It could also be the effect of the treatment.
Brain tumours can sometimes make it hard for people to communicate. They could struggle with language, speech, or understanding. This might be because of the location of the tumour in the brain or the type of treatment being used.
People affected by brain tumours might feel tired, heavy, or weak, or all of these. This can sometimes be because of how the tumour affects the brain or the treatment being used. It could also be the strain of dealing with cognitive difficulties or anxiety, diet and dehydration, pain, seizures, or even higher levels of cytokines, which are immune system proteins.
Understandably, some people who are diagnosed with brain tumours can get depressed. There are lots of things that can cause depression, but it could be because of the tumour affecting the parts of the brain that regulate mood. It could also be because of the diagnosis, which can be a shock, or possibly the way the diagnosis affects the person’s life.
Brain tumours can sometimes make it hard for people to learn, plan, make decisions, concentrate, and make decisions. This might be because of the location of the tumour or its treatments. But, it could also be because of things that can come with brain tumours, like fatigue, epilepsy, depression or anxiety.
Seizures, or epilepsy, can start because of a brain tumour. This could be because of the brain tumour disorganising the electrical activity in the brain. Or, it could possibly because of the tumour creating a chemical imbalance in the brain.
Children who have brain tumours, or have even had them in the past, might struggle to learn things. This could apply to a few different things, like remembering, problem solving, processing, or paying attention. These difficulties could be because of the tumour itself in the brain or some of the other brain tumour side effects, like fatigue.
Brain tumours can cause sight difficulties like dry eyes, abnormal eye movements, light sensitivity, double vision, or loss of vision. This could be because of the position of the tumour in the brain, swelling of the optic disc, pressure on the optic nerve, or possibly the treatment being used.
