13. Personality changes
Not all patients with brain tumors undergo personality changes. They are more likely in patients with brain tumors located in the frontal lobe because this area is in charge of reasoning, morality, differentiating good and bad behaviors, and creating restraints to avoid unaccepted behavior. Thus, these patients may start losing their social restraints and inhibitions.
In many cases, they start displaying emotional problems such as anxiety and depression, and they may also undergo severe behavioral changes with self-destructive patterns. We should differentiate these symptoms from those experiences in diagnosed cancer patients who undergo many different emotional challenges and difficulties.
