Name a common sign of a frontal lobe tumor.

A common sign of a frontal lobe tumor is changes in personality or behavior due to the role of the frontal lobe in regulating emotions, decision-making, and social interactions. The frontal lobe is integral to personal insight, impulse control, and reasoning, which means that any disruption in its function, such as from a tumor, can lead to noticeable alterations in how a person thinks, behaves, and interacts with others. Individuals may display impulsivity, mood swings, irritability, or withdrawal, as they lose the ability to self-regulate their behavior.

Other signs can be associated with frontal lobe tumors, but the distinctive impact on personality and behavior often stands out as a key symptom. This change can sometimes be misinterpreted or attributed to other factors, making it critical for healthcare providers to assess neurological function carefully when personality changes are observed.
