INTRODUCTION: Parkinson's disease (PD) with mild cognitive impairment (MCI-PD) or dementia (PDD) and dementia with Lewy bodies (DLB) are characterised by motor and 'non-motor' symptoms which impact on quality of life. Treatment options are generally limited to pharmacological approaches. We developed a psychosocial intervention to improve cognition, quality of life and companion burden for people with MCI-PD, PDD or DLB. Here, we describe the protocol for a single-blind randomised controlled trial to assess feasibility, acceptability and tolerability of the intervention and to evaluate treatment implementation...

The nerve center responsible for controlling our circadian rhythm is located in a cluster of cells known as the suprachiasmatic nucleus in the hypothalamus. Various physiological functions such as sleep, arousal, blood pressure, body temperature, and hormone secretion are regulated in a 24-hour rhythm by this circuit. Somatic cells of other organs have a peripheral clock gene and by synchronizing the rhythm of the central and peripheral clocks, it is possible to live a healthy life. Due to aging and degenerative disease, circadian rhythm gradually collapses...

Stimulation as well as inhibition of GABAB (Gamma amino butyric acid) receptors has been reported to show beneficial effects in Alzheimer's disease (AD). Experimental evidences suggest that the use of GABAergic agents could influence learning and memory. The present study was designed to investigate the possible role of GABAB receptors in streptozotocin (STZ)-induced behavioral and biochemical abnormalities in rats. Herein STZ was infused (3mg/kg) bilaterally on alternate days (day 1 and day 3) to produce experimental dementia in rats...

Alzheimer's disease (AD) is a common, chronic expensive debilitating neurodegenerative disease with no current treatments to prevent the physical deterioration of the brain and the consequent cognitive deficits. The current pathophysiology of Alzheimer's disease is the accumulation of neurofibrillary tangles (NFTs) of hyperphosphorylated tau protein and amyloid-beta (Aβ) plaques. Antibody therapy of Tau and Amyloid beta, vaccines and other methods to decrease Tau and or Amyloid have not been successful after considerable pharmaceutical and biotech efforts...

OBJECTIVES: White Matter lesions (WML) are a risk factor for cognitive impairment in Parkinson's disease. There is no clear evidence of reduced general cognitive function after DBS. However, a subgroup of patients develops dementia rapidly after DBS despite careful patient selection processes. The aim of this study was to evaluate the load of WML as a possible risk factor for cognitive decline following STN DBS. PATIENTS AND METHODS: 40 PD-patients receiving bilateral STN-DBS were followed at least three years after surgery to detect dementia...

Synapse loss is one of the common factors contributing to cognitive disorders, such as Alzheimer's disease (AD), which is manifested by the impairment of basic cognitive functions including memory processing, perception, problem solving, and language. The current therapies for patients with cognitive disorders are mainly palliative; thus, regimens preventing and/or delaying dementia progression are urgently needed. In this study, we evaluated the effects of catalpol, isolated from traditional Chinese medicine Rehmannia glutinosa, on synaptic plasticity in aged rat models...

BACKGROUND: The most common cause of dementia is Alzheimer's disease. The major manifestation of the disease is the cognitive impairment which appears at the onset of the disease. In addition to the cognitive impairment there are behavioral dysfunctions such as apathy, anxiety, depression and sleep disturbances. The treatment for the manifestations of Alzheimer is currently pharmacological and behavioral. One of the newest behavioral treatments for Alzheimer is the multi-sensory treatment using the Snoezelen room...

Good cognitive abilities (CA) enable autonomy, improve social inclusion and act preventively. Regular physical activity (PA) reduces the risk of developing Alzheimer's disease (AD) and, at the same time, it reduces the decline of CA and stimulates neurogenesis. So PA in connection with cognitive training, nutrition and social interaction has a positive effect on general CA and the central nervous system, the central executor, memory and attention, and reduces the likelihood of developing dementia. Our objective was to examine which sort and intensity of PA is preferred...

REVIEW

Background: Aging naturally triggers a decline in cognition as result of deterioration in cerebral circuits, thus the executive functions (EFs) suffer changes that progress from mild to severe states of impairment. Exercise instead, works as a strategy for cognitive enhancement by modulating neuronal plasticity through the regulation of BDNF. However, whether the exercise-dependent BDNF may improve higher complexity processes such as the EFs is still in a studying process. Results: Current data on exercise-dependent BDNF changes for aging individuals in a course of cognitive impairment was summarized to investigate whether the exercise regulation of BDNF is effective to pronounce long term changes on executive controls...

BACKGROUND: Dementia is a clinical syndrome with a number of different causes which is characterised by deterioration in cognitive, behavioural, social and emotional functions. Pharmacological interventions are available but have limited effect to treat many of the syndrome's features. Less research has been directed towards non-pharmacological treatments. In this review, we examined the evidence for effects of music-based interventions as a treatment. OBJECTIVES: To assess the effects of music-based therapeutic interventions for people with dementia on emotional well-being including quality of life, mood disturbance or negative affect, behavioural problems, social behaviour, and cognition at the end of therapy and four or more weeks after the end of treatment...

INTRODUCTION: Alzheimer disease (AD) is the most common form of dementia in the elderly that slowly destroys memory and cognitive functions. The disease has no cure and leads to significant structural and functional brain abnormalities. To facilitate the treatment of this disease, we aimed to investigate proline-rich peptide (PRP-1) action of hypothalamus on hippocampal (HP) neurons and dynamics of their recovery, after intracerebroventricular (ICV) injection of amyloid-β (Aβ). METHODS: Experiments were carried out on 24 adult, male Albino rats (average weight: 230±30 g)...

The lateral occipito-temporal cortex (LOTC), including the extrastriate body area, is known to be involved in the perception of body parts. Although still controversial, recent studies have demonstrated the role of the LOTC in higher-level body-related cognition in humans. This study consisted of two experiments (E1 and E2). The first (E1) was an exploratory experiment to find the neural correlate of the mental manipulation of body part imagery, in which brain cerebral glucose metabolic rates and the performance of mental rotation of the hand were measured in 100 subjects who exhibited a range of symptoms of cognitive decline...

BACKGROUND: Published in 2009, the German S3 guidelines on dementia define a milestone in quality improvement of the diagnostics and treatment of dementia. In clinical practice patients suffering from dementia are primarily treated by physicians in private practice; therefore, this study examined how the guidelines are implemented in outpatient clinical settings. Furthermore, it aimed at the identification of behavioral determinants that govern the actual diagnostic and therapeutic approach in clinical practice...

Affecting nearly 5.4 million older adults in the United States and 35.6 million individuals worldwide, dementia is one of the greatest public health crises of our time. As a result, helping professionals, clients, and care partners seek effective and affordable treatment. Developed in the United Kingdom by Spector and colleagues, Cognitive Stimulation Therapy (CST) is a non-pharmacologic psychosocial group intervention for persons with dementia. To expand upon and fill the gaps within existing research, the authors developed a descriptive study to assess the impact of CST on cognition, quality of life, and depression, among six CST groups (n = 40)...

Mild cognitive impairment (MCI) is an intermediate stage between normal aging and dementia. The prevalence of MCI among elderly people is 12-17% but the risk of progression of cognitive impairment and development of dementia during 5 years is up to 70%. Cerebral vascular diseases and initial stages of neurodegenerative processes are the cause of MCI. Clinical characteristics of MCI depend on the main etiological factor. To decrease the severity of symptoms and prevent the progression of cognitive impairment in MCI patients, pharmacotherapy and non-medication methods, including diet optimization, stimulation of mental and physical activity, are used...

OBJECTIVE: Early intervention to reduce cognitive decline and preserve functioning is a compelling public health issue. Because impaired attention occurs early in the process of cognitive impairment, focusing training strategies upon attention may be a potential intervention to prevent further cognitive decline. We sought to test the effects on cognitive performance and daily functioning of a new cognitive training program that focuses on attention. METHOD: This single-blind randomized controlled trial lasted 6 months and included two phases...

A systematic review was conducted to identify risk factors associated with the onset and progression of Alzheimer's disease (AD). Moderate and high quality systematic reviews were eligible for inclusion. Primary studies reporting on non-genetic risk factors associated with neuropathologically or clinically confirmed AD were considered. Eighty one systematic reviews reporting on AD onset and 12 reporting on progression satisfied the eligibility criteria. Four hundred and thirty-two relevant primary studies reporting on onset were identified; however, only those published between 2010 and 2012 (n=65) were included in the qualitative synthesis...
