This study will examine self-reported neurocognitive functioning in pediatric cancer survivors whose cancer therapy may have included cranial radiation, intrathecal chemotherapy, and high-dose intravenous antimetabolite chemotherapy. There is evidence that these therapies which are directed at the central nervous system (CNS) can lead to reduced volumes of normal-appearing white matter and neurocognitive dysfunction. Neurocognitive deficits can significantly impact pediatric cancer survivors' academic success, daily functional status, and quality of life. Previous studies demonstrate the need for screening and treating neurocognitive dysfunction in childhood cancer patients and survivors. This pilot study will conduct cognitive debriefing tests with childhood cancer survivors, 30 with and 10 without neurocognitive deficits, and their parents. The collected data will aid in developing a comprehensive patient-reported outcomes (PRO) toolkit consisting of generic and specific cognitive and behavioral domains that are content-appropriate and interface-friendly for pediatric cancer populations. PRIMARY OBJECTIVE: To conduct cognitive debriefing tests with 30 pediatric cancer survivors who have global neurocognitive impairment (i.e., the impaired group) to understand the cognitive process of answering the extant pediatric PRO measures by different levels of general intelligence quotient (IQ). Additionally, 10 pediatric cancer survivors who have at least average general IQ (i.e., the unimpaired group) will be recruited for a comparison purpose. SECONDARY OBJECTIVE: To conduct semi-structured interviews with 30 parents/legal guardians of individuals who have global cognitive impairment as described in the primary objective in order to explore the general concept of their child's neurocognitive functioning, to rank the relative importance of different neurocognitive functioning domains, to inform a strategy for communicating with children and adolescents with impaired neurocognitive functioning for PRO research, and to suggest a user-friendly interface to collect PRO data from cognitively impaired children and adolescents. Additionally, 10 parents/legal guardians of individuals at least average general IQ will be recruited for comparison.

Background: - Human immunodeficiency virus (HIV) infection appears to cause problems with blood vessel function. These problems may add to some thinking and mood disorders found in people with HIV infection. Researchers want to evaluate HIV infected patients to see if blood vessel function contributes to thinking and mood disorders, such as early dementia and depression. To do so, they will compare study results between people with and people without HIV infection. Objectives: To compare the thickness of blood vessel walls between people with and without HIV infection. To study the relationship between blood vessel thickness and thinking and mood disorders. Eligibility: Individuals between 25 and 55 years of age who have HIV infection. Healthy individuals between 25 and 55 years of age. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Participants will have imaging studies of the brain and major blood vessels in the head and neck. Participants will also have neuropsychological testing. These tests will look at memory, learning and thinking ability, attention, and mood. Participants will have the option of coming back for repeat blood tests every six months and repeat imaging studies and neuropsychological tests every year, over 1- 4 years period.

Cognitive Stimulation (CS) in the elderly, as a group intervention, shows benefits on the cognition and quality of life of people with neurocognitive disorder (NCD)(ie, dementia). The evidence of cognitive stimulation as an individualized intervention, conducted at home, by the caregiver is limited. The main objective of this trial is to evaluate the effectiveness of the Individual Cognitive Stimulation Therapy program - "Making a Difference 3 - individual Cognitive Stimulation Therapy (MD3), its acceptability and applicability by the dyad (people with NCD and their caregiver) in the Portuguese population. To achieve this purpose a pilot study will be conducted (randomized control trial), with two moments of evaluation - before the intervention of individual cognitive stimulation and after the intervention in both groups (Group 1 - group subject to intervention: individual cognitive stimulation program called "MD3"; Group 2 - group subject to usual care).The investigators intend to know the effect of the program on cognitive domains, quality of life and relationship between caregiver and care recipient. And, as well as understand the acceptability and applicability of the program by participants (dyad).

CTNPT 029 will test the feasibility and acceptability of cognitive remediation group therapy in older adults living with HIV who have been diagnosed with HIV-associated neurocognitive disorder (HAND). The cognitive remediation therapy will include tablet-based cognitive training and mindfulness-based stress reduction sessions.

This study aims to assess the effectiveness of serious EUREKOI gambling on the anxiety of family caregivers of patients with newly diagnosed Alzheimer's disease.

Dementia is a leading cause of death and disability that was declared as one of the greatest health and social care challenges of the 21st century. Regular physical activity and exercise have been proposed as a non-pharmacological strategy in disease prevention and management. Multicomponent Training (MT) combines aerobic, strength, balance, and postural exercises and might be an effective training to improve both functional capacity and cognitive function in individuals with dementia (IwD). Nevertheless, data on the effects of MT in IwD are still limited and the extent to which IwD can retain improvements after an exercise intervention still needs to be elucidated. The aim of "Body & Brain" study is to investigate the effects of a 6-month MT intervention and 3-month detraining on the physical and cognitive function of IwD. Additionally, we aim to explore the impact of this intervention on psychosocial factors and physiologic markers related to dementia.

The prevalence of HIV-associated neurocognitive disorders (Human Immunodeficiency Virus) remains high during the era of effective triple therapy. The main clinical phenotypes of cognitive impairment are currently represented by asymptomatic neurocognitive neurocognitive impairment (ANI) and mild neurocognitive disorders (MND). In contrast, HIV-associated dementia has almost disappeared. Among the hypotheses to explain the persistence of such a high prevalence is the persistent activation of the immune system despite virological success. This chronic immune activation is believed to be responsible for an inflammatory response and therefore for accelerated cell aging. Several organ complications in HIV-positive patients have been associated with high markers of immune activation. Among the causes of chronic immune activation in virologically controlled patients, an imbalance in the intestinal flora is suspected. In fact, shortly after HIV infection, the virus causes significant apoptosis of intestinal lymphocytes, responsible for a loss of integrity of the intestinal barrier and an imbalance of flora, defined as "dysbiosis". Loss of epithelial integrity and intestinal dysbiosis are suspected of causing systemic passage of bacterial fragments, of which lypopolisaccharide is best known, resulting in chronic activation of the immune system. Several studies suggest a link between digestive bacterial translocation and HIV-related neurocognitive disorders. An improvement in intestinal dysbiosis could therefore contribute to reducing immune activation and the severity of cognitive impairment. A recent study showed that probiotics can reduce levels of neopterin, a marker of monocytic activation, in the cerebrospinal fluid of HIV-positive patients without neurological symptoms. Our objective is to evaluate the impact of probiotic supplementation on immune activation and cognitive performance in virologically controlled HIV-positive patients with a diagnosis of ANI or MND. The potential improvement of cognition through probiotic treatment could therefore improve their quality of life at a lower cost than a drug and without the risk of serious side effects.

Cognitive impairements in Alzheimer's and apparented disorders may lead to the decreased engagement in activities, spetially in moderate and advanced stages of evolution. The lack of stimulation for people with dementia is associated with the risk of challenging behaviors, depressives symptoms, sleeping disorders or faster cognitive deterioration. Those challenges may lead to the increased administration of pharmacological treatments, though the risks of neurleptics use in this population are currently known. In this context, non-pharacological interventions hold a significant place in dementia care. This research focuses on cognitve stimulation activities. More precisly, our study compares two aproaches using the reading groups. The first type (" usual " reading group) is based on the principle of stimulating those cognitive functions which dicreases with the evolution of dementia. The second (Montessori reading group) approach relies on the idea to use preserved capacities in order to compensate the cognitive impariments. The aim of our study is to compare the impact of these two non-pharmalogical interventions on non-verbal communication. The collected datas will help analyzing and understanding the internal and behavioral states of people living with dementia. Our study will also extend relfexions about cognitive stimulation groups in care institutions.
