"Brain tumour personality changes can sometimes occur in people who have
been diagnosed. They can range from a lack of motivation to irritability and
even, sadly, aggression. And, they can have multiple causes. But not everyone
who is affected by a brain tumour will experience personality changes. Sadly,
brain tumours can cause personality changes. For those who do, the symptoms and
severity can differ from person to person. So, you may not have the same
problems as someone with a similar diagnosis and treatment plan.
Our
brains control every aspect of who we are, what we think and how we feel.
It’s perhaps not surprising then, that a brain tumour or its treatment can
cause changes to someone’s personality or behaviour.
Brain
tumour behaviour and personality changes can include irritability or
aggression, confusion and forgetfulness, apathy (lack of interest and
motivation, depression and
flattening of emotion, loss of inhibitions or restraints and behaving in
socially or culturally unacceptable ways, anxiety, mood swings or
extreme moods, difficulty planning and organising, difficulty identifying
emotions in yourself and others.
Simply
knowing there’s a reason you or somebody you know is acting differently
can be a huge relief for some people and help them begin to cope
emotionally.
Brain
tumour behaviour and personality changes can be caused by location of the
tumour. As a brain tumour grows, it puts pressure on the healthy brain cells
around it. This can affect the function, process or part of the body controlled
by that area of the brain.
Personality
changes are most common when a tumour is located in the frontal lobe, which controls
your personality and emotions. It also controls our ability to regulate
our behaviour and restrain ourselves, so tumours that develop in the frontal lobe can cause
behaviour that’s considered socially inappropriate.
Another
possible reason for personality changes is swelling in the brain. This can be
caused by the tumour itself or its treatment, including
surgery, radiotherapy and chemotherapy.
Grade 1 and Grade 2often cause
less swelling than grade 3 and 4, because
they grow more slowly, giving the brain more time to adapt around the
tumour.
Swelling
that occurs as a direct or indirect result of treatment usually
passes gradually as you recover. Often personality changes will pass when
the swelling does.
Confusion
and mood swings can also be the result of medication or a combination of
medications interacting. Some medications, like anti-depressants, can cause
further personality changes.
Personality
changes can also simply be a natural reaction to receiving a brain tumour
diagnosis or its impact on quality-of-life. This can have a huge effect on
someone’s mood and behaviour. Similarly, coping with many of the
side-effects of a brain tumour or its treatments can drastically alter
someone’s mood.
Treatment
and frequent journeys to medical appointments, can also dramatically lower
energy levels. So, it’s common for people to become less active than before. Managing
personality changes will depend on what’s causing them. Often it can
help to talk to people who have experienced something similar and find out what
helps them.
If
swelling around the brain is causing the changes, steroids can be
prescribed to help reduce the effect of the swelling. Some people
are aware of their personality changes, but some people aren’t or they may not
have full awareness.
For example,
someone may be aware they’re now less patient and have a shorter temper, but
not be able to link the cause and the effect. Some people are aware they are
behaving in an inappropriate manner, but will be unable to stop themselves.
This can be a
difficult question to answer as it depends on what aspect of your tumour or
treatment has caused the personality changes you are experiencing.
The change
could be permanent, especially if it’s caused by physical damage to the brain,
for example, as a result of surgery or radiotherapy. In addition to this, if a
person’s tumour continues to grow, personality changes may become more
pronounced or other changes in the personality may begin to appear.
If the change
is due to the emotional impact of living with a brain tumour. There are many
strategies to help you and your loved ones cope better with personality
changes, whether you’re experiencing them temporarily or permanently.
These include
controlling your personality and emotions, and playing a vital role in problem
solving and long-term memory. As a result, personality changes are most common
in people whose tumour is in their frontal lobes. Our ability to regulate our
behaviour and restrain ourselves is also controlled in the frontal lobes. So,
if you have a tumour here, you may act in ways that are considered socially
inappropriate. This can be very difficult for those around you to understand.
It can also be difficult for you, if you are aware that you are doing it, and
it can put a strain on personal relationships.
To help with
confusion, it may be useful to minimise distractions. For example, turn off background noise and
avoid busy, noisy or crowded places that could be overwhelming for the person.
If your loved one
is showing signs of aggression, try to create a calm environment or even remove
your loved one from stressful situations. Try to remain calm and tell them what you’re doing. To help with
aggression, pay attention to what triggers the person’s agitation and try to
resolve the problem before it escalates. For example, there may be something in
particular that’s bothering the person, such as they may be tired or need to
use the bathroom. If your loved one is behaving inappropriately, try not to
show embarrassment or disgust. Instead,
let them know that their behaviour isn’t appropriate, and give them consistent
guidance on how to behave.
To help your loved
one with inappropriate behaviour, it may be useful to speak about this with
other close friends and family. If they have an understanding of the reasons
behind a person’s behaviour, then they’ll be able to support the person or
ignore some comments. Try to avoid comparing the person now with the ‘person
they were before’, which can be upsetting for both of you. You weren’t like
this before. What’s gone wrong?
Try to recognise
the change as part of the brain tumour, not the person you love. This can be
very difficult if, for example, the person becomes irritable or snappy and it
seems as though they’re taking everything out on you.
Take time to look
after yourself. Caring for, or living with, someone whose personality has
changed can be wearing - make sure you set time aside for yourself. For
example, to do a hobby or something you enjoy. And ask for help if you need
time to recharge your batteries."
When I read this now I wonder could I have been better, could I have behaved better towards Catherine? Was I selfish? Or did I do this best I could?
