5. Personality Or Mood Fluctuations
Depending on where the tumor is and how big the swelling is, patients with brain tumors could find their personality or moods changing in ways different from before, and inexplicably so. They may like things they never did before and vice versa. It could be more extreme than this: adult patients may, for example, laugh at inappropriate times, have a sudden surge in sex drive, throw temper tantrums, exhibit toddler-like behavior, become paranoid, or engage in risky social and other activities.
It’s also possible that your existing personality becomes magnified. In other words, your likes, fears and general inclinations may be magnified instead of changing. Your existing personality traits may become extreme. Brain tumor patients have been known to develop what seems like depression but are not ‘true’ or real depression. In this way, brain tumors are like aneurysms, which also cause inexplicable personality changes. Aneurysms are blood swellings within the veins or arteries that could burst and be fatal.
