Glioblastoma (GBM) significantly alters personality by damaging brain areas controlling emotions and behavior, leading to increased irritability, aggression, apathy, impulsivity, confusion, depression, and significant mood swings, often manifesting as difficulty with social judgment, disinhibition, or emotional control, sometimes compounded by the psychological stress of the diagnosis. These changes stem from the tumor pressing on or swelling the brain, especially in the frontal and temporal lobes, impacting functions like empathy, motivation, and social understanding.
Glioblastoma symptoms can be gradual and undetectable at first. Headaches, confusion, memory loss, motor weakness, and seizures are common. Nausea, personality changes, difficulties concentrating, hemiparesis, and aphasia are among some other symptoms experienced by patients.
Glioblastoma is a type of cancer that starts as a growth of cells in the brain or spinal cord. It grows quickly and can invade and destroy healthy tissue. Glioblastoma forms from cells called astrocytes that support nerve cells. Glioblastoma can happen at any age.
The few existing reports identified symptoms related to increased intracranial pressure (headache and drowsiness), as well as progressive neurological deficits, epileptic seizures, confusion/delirium, fatigue, and dysphagia as the most prominent symptoms.
Brain tumors may affect your ability to think, learn, reason, and remember (called cognitive problems). Many people with brain tumors also have problems with these kinds of thinking skills: Concentration, focus, or ability to pay attention.
Sadly, brain tumours can cause personality changes. In fact, 1 in 3 people we spoke to had experienced personality changes caused by a brain tumour or its treatment.
Causes of Personality and Behavior Changes
Risk factors of glioblastoma
Exposure to chemicals, like pesticides, petroleum, synthetic rubber and vinyl chloride. Genetic, tumor-causing conditions, like neurofibromatosis, Li-Fraumeni syndrome and Turcot syndrome. Previous radiation therapy to your head.
The average life expectancy for glioblastoma patients who undergo treatment is 12-15 months and only four months for those who do not receive treatment. Nearly 28% of brain and central nervous system (CNS) tumors are malignant, and nearly 50% of those malignant tumors are Glioblastoma.
How to support someone with a brain tumour
There are no studies with conclusive evidence to say that stress causes glioblastoma or any other type of glioma. However, we do know that overwhelming amounts of stress can reduce immune system function (the part of your body that fights off disease and tumors).
Who gets glioblastomas? Glioblastomas tend to develop in men more often than in women, in people 50 or older, and in Caucasians.
Vision changes
Blurry vision, double vision, and loss of vision are all associated with tumors, Schwartz says. You may also see floating spots or shapes—or what's known as an "aura."
Patients with glioblastoma are often struggling with a great deal of physical and emotional burdens. It is important to listen to them, even if they are unable to communicate verbally.
It has been suggested that COVID-19 infections are associated with a unique brain predisposition to thrombosis caused by cytokine storms (9), which is correlated with faster GBM development. Poor prognosis is associated with tumor thrombus in GBM (10).
Behavior changes (also called personality changes) are common for people with a moderate or severe TBI. These changes often occur soon after the TBI and may change across time. The types of changes people have and how long they last depend on where their injury is, how severe it is, and other factors.
Glioblastoma signs of decline
Because glioblastoma is difficult to treat, the patient's symptoms will eventually get worse. He or she may be sleepy and spend more time sleeping, and the patient may have headaches and nausea. It'll get harder to move and speak, and the patient may have problems swallowing or seeing.
If you have a fast growing (grade 3 or 4) glioma, you cannot drive for 2 years. You may be able to drive again after 2 years if you are not having seizures and you don't have any disability that affects your ability to drive.
Yes, they can. Brain tumors often cause personality changes and sudden mood swings. Although these mood changes and their severity will vary from one person to another, it's relatively common for someone with a brain tumor to experience increased: Aggression.
1. Myth: Cell phones cause glioblastoma. Fact: To date, there is no established link that cell phones cause glioblastoma. Several different studies have failed to find clear evidence of a link between cell phone use and brain cancer.
Exposure to ionizing radiation therapy—especially to the head or neck—has been identified as a glioblastoma risk factor. Some studies have linked occupational exposure to certain chemicals to an increased risk for brain tumors, but other studies have found no such correlation.
Limit or avoid animal products such as meat, dairy, and eggs. Get adequate protein intake through legumes, tofu, tempeh, and other plant-based protein sources.
If you feel you are having a nervous breakdown you may:
And they can track how those traits increase or decrease in a group over time. To the surprise of many in the field, those kinds of studies are revealing that the strongest personality changes tend to happen before age 30—and after 60.
