Psychological aspects in brain tumor patients: A prospective study.

ABSTRACT

OBJECTIVE: Very few studies have utilized specific criteria to assess mental disorders in brain tumor patients, and from them, they are mainly descriptive. The purpose of this study is to examine mental disorders in relation to tumor characteristics and patients' psychosocial factors using DSM-IV (depression, sleep and mood) criteria, among brain tumor patients. MATERIALS AND METHODS: From March 2009 to July 2011, 98 patients who surgically treated with intracranial neoplasm were included in this prospective study. The mean age of the patient group was 42.2 years with a range of 18-60 years with a male to female ratio of 1.2. The most common tumor type was glioblastoma multiform (30.3%), followed by meningioma (16.8%) and anaplastic glioma (12.3%). RESULTS: In our study, the prevalence of mild depression was about 30% for males and 38% for females before surgery; however at 3 months after surgery, this amount decreased to the amount of 25.6% and 26% for male and female patients respectively. Before tumor operation, the prevalence of major depression was 10.4% for males and 19.7% for females. At 3 months after operation the prevalence of major depression was 12.8% for males, and 6.7% for females. Aggression or suicide attempts were not seen related to depression. Before operative intervention, severe anxiousness as well as severe Obsessive Compulsive Disorder (OCD) symptoms was present in 14.7% of males while at 3 months after operation, prevalence of severe anxiousness and severe OCD symptoms decreased to 4% and 9.3% respectively. In females, 28.7% of the subjects had reported to have severe anxiousness and 25.6% severe OCD symptoms. Three months after surgery, these amounts were 17.6% and 38.7% respectively. CONCLUSION: Depressive symptoms as well as anxious and OCD psychopathology were shown to be prevalent signs among patients with brain tumor. Diagnosis of the previous mentioned symptoms were totally based on DSM-IV criteria and these disorders and the percentiles don't seem to be related to each other. Due to high variability of tumor stages, statistical analysis of whether the mentioned psychiatric symptoms get worsen at the later stages of the tumor genesis was not feasible. Although not measured directly, mentioned psychiatric symptoms seem to get worsen at the later stages of the brain tumor. The associated factors are tumor location, patient's premorbid psychiatric status, cognitive symptoms and adaptive or maladaptive response to stress.
