Can a brain tumor cause extreme personality or behavioral changes?

[Hityty]

My 50 yo sister-in-law was diagnosed w/a pituitary brain tumor 7 yrs ago. She began extensive natural therapies, she's been healthy & happy since w/no more symps of BT. But this last yr her personality has changed significantly. She has turned on her entire family: husband, 3 bro

Wow, I know EXACTLY what you mean. My boyfriend has an inoperable brain tumor, and he has become very hard to be around due to his extreme personality changes.  He yells and swears at me all the time to the point of my crying.  He also is bipolar, so between the two, he is becoming unbearable to be around.  Last night he went to the extreme of "verbally attacking" my granddaughter whose four-week old son passed away a month ago of SIDS.  He called 911 because of something he thought she said.  The entire evening was an embarrassment to everyone concerned.  Last night he ended our relationship, then he texted me and said nice things to me.  This is what I mean about extreme personality changes.  I am at a loss as to what to do at this point.  The cancerous brain tumor is supposed to be "a secret" from everyone, but it's coming to the point that I am going to have to tell people because it's becoming more and more noticable.

I'm in the same boat. He wants to keep it a secret from everyone and has systematically cut off the majority of his friends. He threatened to kill me last night- twice. Not even sure why. I called his parents and let the cat out of the bag. It seems it's too late. They drank the Koolaid and believe that this must just be some elaborate plot that I created. On top of it, I got news that my grandmother is dying. He knows, and came at me anyway. I hope you've found a way out since your post.

My mom had three brain surgeries and all tumers were located in the front part of her brain and also on her forehead all were removed and the only side effect she had was DRAMATIC persanality change. She is 55years old and acts like shes in her twenties. She has turned her back from her children and our father her husband for over33 years. She had said she lacks emotions she does't feel. before all her surgeries her persanality was church and home. Oh and her sex drive is thru the roof and she is heartless and very aggresive with our father. Sometimes I feel like we are living in a movie.

My name is Orlando I recently had brain surgery due to a blood clot in my brain, due to I was in a car accident. And about a few weeks after I left the hospital I have felt very weird, rebellious, and extremely angry. I also feel as if I am two different people. One person is a very nice person. But the other person is a person that gets so angry so fast and then turns against everyone, and just wants to go against the world. I feel as if I have split personalities. I wonder if I will ever be normal again? And what gets me the angriest is when someone try's to tell me im lieing about my pain, becuz I am not. Just becuz I don't complain all day about how bad I feel, becuz I don't want people to feel as if they are obligated to help me or feel bad for me. If anybody has any answers or links or anything PLEASE HELP! I feel as if I am going to die soon.

Hello. I was diagnosed with a grade rwo cancerous Astrocytoma Brain Tumor at age nine. It was removed and since then, I have experienced personality changes. Prior to the surgery I was an optimistic girl with high hopes, great grades, easy to be around and extremely friendly. As it stands today, I am more of a pessimist, always seeing the dark before the light, I have a harder time makeing friends than before and can fly off the handle pretty easily. When you experience such a trauma as having a tumor removed or even an injury to the brain, if it has affected the correct area, you will experience emotion imbalances and changes. I am now doing my senior resaerch project on how anomolies or anjuries to the brain affect ones personality. I hope everything works out for you and your family in the end.

Hi, I was diagnosed in May 2007 with a pituitary tumour. I was put on testo gels and cabergoline.   The symptoms started in 2001 with severe headaches and mood swings.  I used to get angry over everything and anything and suffered from severe road rage every time a got in the car.  I began became very distant and emotionally detached from everyone including my wife.  I started to self-harm and always felt tired and angry.  I felt like  there was a black cloud hanging over me the whole time.  I contemplated suicide on more than one occassion.  My violent outbursts were directed at my wife whom I had loved more than anything in the world.  I started to question whether I had ever actually loved her.  We separted in 2010.  In the last 6 months I have stared to feel like I was waking up again.  I am now aware of my mood swings and I'm able to control them.  I felt nothing when my wife moved out but lately I have started to rember how much I love her and I miss her so much.  We have both been through a lot because of my illness and I can never apologise enough to her for all the pain and suffering I caused her.  She stood by me even after we separated.  

The point that I'm trying to make is that the tumour and/or the meds do have an impact on your personality and it's important to write down your feelings so that you remember what you were like before the illness started.
