BACKGROUND: Neuromodulatory interventions like transcranial direct current stimulation (tDCS) is emerging as a potential therapeutic strategy to promote cognitive function in healthy and pathological aging. There is need for more studies evaluating the utility and tolerability of tDCS in Mild cognitive impairment (MCI). Since MCI is considered as the prodromal stage of dementia, it has emerged as the most important target for intervention in dementia. OBJECTIVE AND METHOD: This study investigated the feasibility, tolerability and clinical utility of tDCS in patients with MCI...

According to the Alzheimer Society of Canada, within the next generation, Canada will experience a more than doubling of individuals living with dementia and a potentially economically crippling 10-fold increase in costs to Canadians. Up to 50% of cases with dementia can be attributed to seven modifiable, predominantly vascular and/or lifestyle-associated, risk factors. Multi-modal dementia risk reduction strategies, targeting diet, exercise, mental stimulation, and vascular risk monitoring, are likely to be the most successful...

Despite the growing international innovations for visual arts interventions in dementia care, limited attention has been paid to their theoretical basis. In response, this paper explores how and why visual art interventions in dementia care influence changes in outcomes. The theory building process consists of a realist review of primary research on visual art programmes. This aims to uncover what works, for whom, how, why and in what circumstances. We undertook a qualitative exploration of stakeholder perspectives of art programmes, and then synthesised these two pieces of work alongside broader theory to produce a conceptual framework for intervention development, further research and practice...

James Papez worked on the anatomical substrates of emotion and described a circuit, mainly composed of the hippocampus, thalamus and cingulum, and published his observations in 1937. However, such an idea existed before him, as evidenced by the rudimentary indications from Paul Broca, and Paul MacLean added some other structures like, septum, amygdala, and hypothalamus in its ambit and called it the limbic system. Paul Ivan Yakovlev, proposed a circuit which also referred to orbitofrontal, insular, anterior temporal lobe, and other nuclei of thalamus...

BACKGROUND: Among the various complementary therapies for patients with dementia (PwD), cognitive stimulation therapy (CST) and reminiscence therapy (RT) are frequently used to improve cognitive function and quality of life. However, no studies have examined the use of complementary therapies applied to different types of behavioural and psychological symptoms of dementia in PwD. AIMS: The purpose of this study was to investigate the distinctive effects of CST and RT on cognitive function and quality of life for PwD with three types of behavioural problems - the dispute, return and dissociate types...

A 44-year-old man made many mistakes at work over a year. Eleven years prior, he had had medical examination with headache. He presented with symptoms consistent with frontal lobe dysfunction including cognitive decline, and bilateral pyramidal signs. Brain MRI showed cerebral atrophy, localized atrophy of corpus callosum, asymmetrical white matter lesions and multiple cystic lesions. CT images showed bilateral calcifications in the parietal subcortical white matter. Reconstructed sagittal CT images showed bilateral calcifications in the frontal white matter adjacent to the anterior horns of the lateral ventricles, which had a symmetrical "stepping stone appearance" in the frontal pericallosal regions...

Alzheimer's disease (AD) is the main cause of dementia and a major health issue worldwide. The complexity of the pathology continues to challenge its comprehension and the implementation of effective treatments. In the last decade, a number of possible targets of intervention have been pointed out, among which the stimulation of 5-HT4 receptors (5-HT4Rs) seems very promising. 5-HT4R agonists exert pro-cognitive effects, inhibit amyloid-β peptide (Aβ) production and therefore directly and positively impact AD progression...

Subcortical ischemic vascular cognitive impairment (SIVCI) is the most preventable form of cognitive dysfunction. There is converging evidence from animal and human studies that indicate vascular injury as the primary cause of SIVCI. Currently, there are no curative pharmaceutical treatments for vascular dementia; however, exercise may be a promising strategy to combat SIVCI. This review will focus on the role of exercise as a strategy to prevent or slow the progression of SIVCI, with particular emphasis on the mechanisms by which exercise may improve cerebrovascular function...

Due to the improvement of medical level, life expectancy increased. But the increased incidence of cognitive disorders is an emerging social problem. Current drugs for dementia treatment can only delay the progress rather than cure. p-Coumaric acid is a phenylpropanoic acid derived from aromatic amino acids and known as a precursor for flavonoids such as resveratrol and naringenin. It was shown to reduce oxidative stress, inhibit genotoxicity and exert neuroprotection. Based on these findings, we evaluated whether p-coumaric acid can protect scopolamine induced learning and memory impairment by measuring LTP in organotypic hippocampal slice and cognitive behaviors in rats...

Parkinson's disease (PD) is a common neurodegenerative disorder, characterized by motor and nonmotor symptoms (NMS). Several subsequent studies substantiate the great functional burden related to NMS, their progression, and negative effect on quality of life in PD. Additional evidence indicates interesting relationships between striatal dopaminergic function and NMS. The basal ganglia are implicated in the modulation and integration of sensory information and pain, bladder function is under control of both inhibitory (D1) and facilitatory (D2) dopaminergic inputs, finally reduced dopaminergic activity in the mesocortical and mesolimbic pathways is involved in the development of several NMS including mood, motivational, and cognitive alterations...

The use of Serious Games (SG) in the health domain is expanding. In the field of neurodegenerative disorders (ND) such as Alzheimer's disease, SG are currently employed both to support and improve the assessment of different functional and cognitive abilities, and to provide alternative solutions for patients' treatment, stimulation, and rehabilitation. As the field is quite young, recommendations on the use of SG in people with ND are still rare. In 2014 we proposed some initial recommendations (Robert et al...

BACKGROUND: Because of the enormous social and economic burden of disease, the prevention of mild cognitive impairment and Alzheimer's-type dementia has become a major global public health priority. Studies show that cognitively stimulating activities during middle adulthood might have a protective effect on the brain by boosting the cognitive reserve. The aim of this review is to identify evidence investigating the effects of continuing education for the prevention of mild cognitive impairment and Alzheimer's-type dementia in late life...

BACKGROUND: Recent evidence suggests that glucosidase beta acid (GBA) mutations predispose Parkinson's disease (PD) patients to a greater burden of cognitive impairment and non-motor symptoms. This emerging knowledge has not yet been considered in patients who have undergone deep brain stimulation (DBS); a surgery that is generally contraindicated in those with cognitive deficits. OBJECTIVE: To explore the long-term phenotypic progression of GBA-associated PD, in a DBS cohort...

The benefits of Cognitive Stimulation Therapy in supporting cognitive functioning for people with dementia are well recognised. It has been proposed that Cognitive Stimulation Therapy may offer additional benefits in terms of a person's sense of general wellbeing. A service evaluation of 60 participants attending Cognitive Stimulation Therapy groups was conducted using the Short Warwick-Edinburgh Mental Well-Being Scale. Although this evaluation did not demonstrate a significant difference between pre- and post-treatment scores (t = -1...

This article reviews current treatment strategies and recent advances for the Lewy body dementias (LBDs). Current available symptom treatment strategies are based on monoaminergic, cholinergic and glutaminergic neurotransmitter systems. Relatively robust evidence exists for cholinesterase inhibitors for cognitive impairment in LBD and in Parkinson's disease for antidepressants, clozapine and recently pimavanserin for psychosis. interpidine (RVT 101) and nelotanserin are currently under investigation. Non-pharmacological interventions, such as cognitive stimulation, physical exercises and neuromodulation strategies, may be useful in Parkinson's disease but have not yet been tested in dementias...

BACKGROUND: Alzheimer's disease is an age-related neurodegenerative disorder characterized clinically by a progressive loss of memory and cognitive functions resulting in severe dementia. Ipriflavone (IPRI) is a non-hormonal, semi-synthetic isoflavone, clinically used in some countries for the treatment and prevention of postmenopausal osteoporosis. Moreover, ipriflavone is a non-peptidomimetic small molecule AChE inhibitor with an improved bioavailability after systemic administration, due to its efficient blood-brain barrier permeability in comparison with peptidomimetic inhibitors...
