Neuropsychiatric symptoms as early indicators of brain tumors.

Brain tumors, despite the high mortality and morbidity, they are a rare type of heterogenous tumors that are highly dependent on sex, age, race, level of education, and socioeconomic status. Due to their high mortality rates, it is important to identify as many potential biomarkers for early detection as the earlier the tumor is discovered, the better the prognosis. One such early biomarker we propose in the current paper is the assessment of anxiety, depression, and cognitive changes. In most cancer patients, a certain degree of anxiety and depression is expected upon receiving the diagnosis as it triggers fears regarding the prognosis, possible side effects of the treatment, and even the possibility of the treatment failing. In this paper we analyzed the way anxiety, depression, and cognitive changes present themselves in the case of several types of tumors and whether these could be used as early markers. We have observed that most of the cognitive changes present are due to the location, size, and type of the tumor with some highly connected to anxiety and depression. Moreover, in the case of certain tumors, the removal of the mass has not improved the mood or cognitive function.
