Brain tumor is a diagnosis that causes major changes in the patient's mood and behavior, but less is known that even before diagnosis the patient may behave differently.

Diagnosis should be made, although other symptoms of the dangerous disease have not appeared.

Small psychological changes can be a symptom of a brain tumor, reports Telegrafi.

When, for example, a person begins to show jokes that are not characteristic of him or exhibit behaviors or traits that were not characteristic of him until then, these are the first symptoms that are often overlooked.

Usually the changes are explained by several other reasons, because maybe someone has had a death, or has quarreled with the spouse.

Behavioral changes occur mainly because the tumor presses on a certain part of the brain or causes it to swell.

It also affects the pituitary gland, which affects mood, causing hormone deficiency or excess.

Behavioral changes can vary in intensity and intensity - from mild melancholy, through apathy to aggression.

Once diagnosed with a brain tumor, the patient may be even more mentally unstable.

Chemotherapy and other treatments can have similar effects.

Of course, not every change in behavior is a symptom of a brain tumor.

Stress, fatigue, hormonal imbalance also lead to changes and the possibility of serious mental disorders such as anxiety, dementia or schizophrenia should not be ruled out.
