Major Depressive Disorder (MDD) is common among cancer patients, with prevalence rates up to four-times higher than the general population. Depression confers worse outcomes, including non-adherence to treatment and increased mortality in the oncology setting. Advances in the understanding of neurobiological underpinnings of depression have revealed shared biobehavioral mechanisms may contribute to cancer progression. Moreover, psychosocial stressors in cancer promote: (1) inflammation and oxidative/nitrosative stress; (2) a decreased immunosurveillance; and (3) a dysfunctional activation of the autonomic nervous system and of the hypothalamic-pituitaryadrenal axis...

Cancer survivors diagnosed during infancy and adolescence may be at risk for chemotherapy-related cognitive impairments (CRCI), however the effects of pediatric chemotherapy treatment on adulthood cognitive function are not well understood. Impairments in memory, attention and executive function affect 15-50% of childhood leukemia survivors related to methotrexate exposure. Systemic cisplatin is used to treat a variety of childhood and adult cancers, yet the risk and extent of cognitive impairment due to platinum-based chemotherapy in pediatric patients is unknown...

Despite multimodal treatment with surgery, radiotherapy and chemotherapy, glioblastoma is an incurable disease with a poor prognosis. During the disease course, glioblastoma patients may experience progressive neurological deficits, symptoms of increased intracranial pressure such as drowsiness and headache, incontinence, seizures and progressive cognitive dysfunction. These patients not only have cancer, but also a progressive brain disease. This may seriously interfere with their ability to make their own decisions regarding treatment...

Reduced triiodothyronine (T3) concentrations were implicated in worse prognosis of brain tumor patients. In this study we investigated the association of normal and abnormal thyroid hormone concentrations with health-related quality of life (HRQoL) of patients with primary brain tumors. Sixty-three patients (67% women and a mean age of 55.5 ± 13.8 years) before brain tumor surgery were evaluated for: (1) HRQoL using the EORTC questionnaire for cancer patients (QLQ-C30) and the Brain Cancer-Specific Quality of Life Questionnaire (QLQ-BN20); (2) functional status (Barthel Index); and (3) clinical disease severity...

Tamoxifen (TAM) is most commonly prescribed for patients with hormone-sensitive breast cancer and exerts agonistic/antagonistic effects on estrogen receptors throughout the body. Accumulating evidence has revealed that breast cancer patients receiving TAM manifest cognitive dysfunction. However, whether these patients have a global attention deficit or a more selective impairment of specific attention networks remains unknown. In the present study, we sought to explore the attention function of premenopausal women with hormone receptor-positive breast cancer treated with TAM using the attention network test (ANT)...

Importance: A growing body of evidence supports a link between androgen deprivation therapy (ADT) and cognitive dysfunction, including Alzheimer disease. However, it is currently unknown whether ADT may contribute to the risk of dementia more broadly. Objective: To use an informatics approach to examine the association of ADT as a treatment for prostate cancer with the subsequent development of dementia (eg, senile dementia, vascular dementia, frontotemporal dementia, and Alzheimer dementia)...

Cancer survivors are exposed to several risk factors for cognitive dysfunction, such as general anesthesia, surgical trauma, and adjuvant therapies. In our recent study we showed that thalamic volume reduction and attentional dysfunction occurred shortly after surgery. Here, we examined the 6-month prognosis of the 20 patients with breast cancer who underwent surgery. Seven patients did not receive any adjuvant therapy after the surgery and 13 patients received a hormonal therapy after the surgery. We assessed their attentional functions, and thalamic volumes shortly after and 6 months after surgery...

The unintended side effects of cancer treatment are increasing recognized. Among these is a syndrome of long-term neurocognitive dysfunction called cancer/chemotherapy related cognitive impairment. To date, all studies examining the cognitive impact of cancer treatment have emphasized chemotherapy. Radiation-induced bystander effects have been described in cell culture and, to a limited extent, in rodent model systems. The purpose of this study was to examine, for the first time, the impact of non-brain directed radiation therapy on the brain in order to elucidate its potential relationship with cancer/chemotherapy related cognitive impairment...

Cancer and treatment-related neurocognitive dysfunction (CRND) - impairments in aspects of cognition commonly including attention and memory, information-processing speed, and executive functioning - can negatively affect patients' and survivors' participation in routine activities of daily living and overall quality of life. CRND can be enduring, and varies in severity level. The epidemiology of CRND is not yet clearly established; reported incidence has ranged from 17% to 75% among patients and survivors of noncentral nervous system malignancies, including breast, prostate, cervical, and colorectal cancers...

Paraneoplastic neurological syndromes (PNSs) are rare nervous system dysfunctions in cancer patients, which are primarily observed with small-cell lung cancer, gynecological cancer, and thymoma. We herein present an uncommon case of PNS in an anti-Hu antibody-positive patient with human epidermal growth factor receptor (HER)-2-positive gastric cancer (GC), who developed limbic encephalitis and a worsening cognitive function. Trastuzumab-combined chemotherapy was initiated and appeared to be partially effective for controlling the neurological symptoms and tumor volume...

BACKGROUND: Testicular cancer is one of the most common and most treatable cancers in men aged 15-49 years. The high survival rates mean that it is essential to maintain quality of life and minimize adverse effects associated with treatment. Both malignant tumors and the modalities used to treatment them can have adverse effects from both a psychosocial and a neurocognitive function perspective. Recently, attention has focused on the negative impact of the disease and its treatment on the brain and on cognitive function, which can result in a form of neurocognitive dysfunction known as "chemo brain" or "chemo fog"...

Clinical studies indicate that up to 70% of cancer patients who receive chemotherapy experience cognitive impairment. The present study investigated environmental enrichment as a protective factor against the adverse effects of anticancer drugs on cognitive and biological processes in an animal model. Adult rats were housed in group cages with environmental stimulation or in standard cages for 3 months, before receiving 3 weekly injections of methotrexate + 5-fluorouracil, or equal volumes of saline. Rats were then administered tests of learning and memory that are sensitive to hippocampal or frontal lobe dysfunction...

Chemobrain or chemotherapy induced cognitive impairment (CICI) represents a new clinical syndrome characterised by memory, learning and motor function impairment. As numerous patients with cancer are long-term survivors, CICI represent a significant factor which may interfere with their quality of life. However, this entity CICI must be distinguished from other cognitive syndromes and addressed accordingly. At the present time, experimental and clinical research suggests that CICI could be induced by numerous factors including oxidative stress...

Cancer and neurocognitive disorders, such as dementia and delirium, are common and serious diseases in the elderly that are accompanied by high degree of morbidity and mortality. Furthermore, evidence supports the under-diagnosis of both dementia and delirium in older adults. Complex questions exist regarding the interaction of dementia and delirium with cancer, beginning with guidelines on how best measure disease severity, the optimal screening test for either disorder, the appropriate level of intervention in the setting of abnormal findings, and strategies aimed at preventing the development or progression of either process...
