Insomnia among brain tumor patients: a population-based prospective study of tumor patients in northern Finland.

Patients with neurological diseases often suffer from sleep disturbances. Insomnia among adult brain tumor patients has usually been studied as part of quality-of-life studies, or some case reports on insomnia in these patients have been described. The authors aimed to study insomnia in a prospective study setting among patients with primary brain tumors and evaluate whether insomnia is related to tumor laterality.

Depression in relation to anxiety, obsessionality and phobia among neurosurgical patients with a primary brain tumor: a 1-year follow-up study.

Depression is found to be present in up to 44% of brain tumor patients during their illness process. Anxiety as a comorbid psychiatric disorder with depression has formerly been studied, but phobia or obsessive-compulsive symptoms among brain tumor patients have not yet been noticed. By using a clinical prospective database of primary brain tumor patients (n=77) we studied the level of depression, anxiety, obsessionality (traits and symptoms) and phobic anxiety symptoms.

Somatization symptoms are related to right-hemispheric primary brain tumor: a population-based prospective study of tumor patients in northern Finland.

Background: Somatization symptoms have been found to be early symptoms of tumor among brain tumor patients.

Objective: The authors followed patients through diagnosis of brain tumor and subsequent surgery.

Method: Patients with a supratentorial tumor were given repeated measurements for somatization with the Crown-Crisp Experiential Index.

Season of tumor surgery in relation to deaths among brain tumor patients: does sunlight and month of surgery play a role in brain tumor deaths?

The objective of this study is to investigate the effect at the season of the time of surgery on the survival of brain tumor patients. The population studied consisted of 101 patients (39 males and 62 females), gathered from a geographically large area in northern Finland (from 64 degrees N to 70 degrees N), aged between 20 and 82 years, with a solitary primary brain tumor treated surgically at the Oulu Clinic for Neurosurgery, Oulu University Hospital. The distribution of tumor surgery dates and mean hours of sunshine hours was analyzed by bimonthly periods.

Decreased quality of life and depression as predictors for shorter survival among patients with low-grade gliomas: a follow-up from 1990 to 2003.

Objectives: To assess the long-term survival of brain tumor patients, and in particular to evaluate the relation of quality of life (QOL) to survival among low-grade glioma patients.

Methods: The postoperative survival of 101 brain tumor patients was followed from surgery (1990-1992) until the end of the year 2003. Depression was evaluated by the Beck Depression Inventory (BDI) and QOL with Sintonen's 15D scale before operation and at one year as well as at five years after operation.

Winter birth in association with a risk of brain tumor among a Finnish patient population.

The aim of this study was to analyze whether winter birth is related to risk of brain tumor in a clinical sample of patients from northern Finland. The study group comprised 101 patients suffering from a primary brain tumor. When comparing births in winter to births in other seasons, a 1.

Depression and functional outcome in patients with brain tumors: a population-based 1-year follow-up study.

Object: The authors analyzed changes in depression and contemporary functional states by using valid tools in a population-based study sample during a 1-year follow-up period.

Methods: The study population consisted of 77 patients with a solitary primary brain tumor treated surgically at the Oulu Clinic for Neurosurgery. Each patient's depressive status, according to the Beck Depression Inventory (BDI), and functional outcome, based on the Karnofsky Performance Scale (KPS), were evaluated before the tumor was surgically treated as well as 3 months and 1 year after surgery.

Level of obsessionality among neurosurgical patients with a primary brain tumor.

Obsessive-compulsive symptoms have been associated with different types of damages or dysfunctions in the brain. However, the accumulated evidence on obsessive-compulsive symptoms among patients with a primary brain tumor is so far based on case reports only. The study population consisted of 59 neurosurgical patients with a primary brain tumor.

Gender difference in relation to depression and quality of life among patients with a primary brain tumor.

Objective: We studied the relationship between depressive symptoms and quality of life (QOL) as well as functional status in primary brain tumor patients at recurrent measurements. Differences in QOL between depressive and non-depressive samples by gender were controlled for tumor characteristics and patients' psychosocial factors.

Materials And Methods: The data consisted of 77 patients with a primary brain tumor, 30 males and 47 females.

Depression in relation to survival among neurosurgical patients with a primary brain tumor: a 5-year follow-up study.

Objective: The adverse impact of depression in relation to survival among cancer patients is currently a subject of great interest in research. In a 5-year follow-up study, we investigated the association of depression with survival of patients with a primary brain tumor.

Methods: The study population consisted of 75 patients with a solitary primary brain tumor treated surgically at the Oulu Clinic for Neurosurgery, Oulu University Hospital, in Northern Finland.
