As patients lose cognitive function, they lose autonomy and increasingly use fiscal, social, and medical resources. Healthcare costs for Americans older than age 65 years are three to five times higher than for the remaining population, and dementia is the third most costly disease in the United States. Interventions that promote successful aging can help patients and reduce the financial, workforce, and treatment resource burdens on the population. Because a relationship between physical activity, particularly aerobic exercise, and cognitive decline has been established, physical activity interventions may prove practical, affordable, and effective...

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...

Several studies have shown that physical activity has positive effects on cognition in healthy older adults without cognitive complains but lesser is known about the effectiveness of aerobic exercise in patients suffering from Mild Cognitive Impairment (MCI). The aim of the present study was to systematically review the evidence from randomized controlled trials (RCTs) about the effects of aerobic exercise upon cognition in MCI patients. To this end, PubMed, Cochrane and Web of Science databases were analytically searched for RCTs including aerobic exercise interventions for MCI patients...

Physical activity has been proposed as a promising intervention to improve cognition and decrease the risk of dementia in older adults. Brain-derived neurotrophic factor (BDNF) appears to mediate, at least partially, these effects of exercise. However, intervention studies of the effects of multimodal exercises on cognition and BDNF levels are scarce and composed by small samples. Thus, the generalization of the conclusions of these studies depends on the reproducibility of the results. In order to contribute to the knowledge on the field, the present study evaluated the effects of a physical activity intervention composed by muscle strengthening and aerobic conditioning on BDNF levels and cognition in older women...

BACKGROUND: Behavioral disorders such as aggressiveness, agitation, delusions, disinhibition, affect lability, and apathy arise in more than 90% of patients with dementia. Behavioral disorders are a major challenge and the greatest stress factor in everyday life for nursing personnel and for family members caring for the patient. METHODS: This review is based on relevant publications retrieved by a selective literature search in the PubMed, Cochrane Library, and German S3 guideline databases with the search terms "behavioral disorders," "non-cognitive disorders," and "challenging behavior," in conjunction with "dementia" and "behavioral and psychological symptoms of dementia...

BACKGROUND: People with dementia are at high risk for falls. However, little is known of the features causing falls in Alzheimer disease (AD). Our aim was to investigate how participants with AD fall. METHODS: In the FINALEX (Finnish Alzheimer Disease Exercise Trial) study, participants' (n = 194) falls were followed up for 1 year by diaries kept by their spouses. RESULTS: The most common reason for falls (n = 355) was stumbling (n = 61). Of the falls, 123 led to injuries, 50 to emergency department visits, and 13 to fractures...

REVIEW
Angela M Sanford
Mild cognitive impairment (MCI) occurs along a continuum from normal cognition to dementia. A roadblock to earlier diagnosis and potential treatment is the lack of consistency with screening for MCI. Universal screening would be ideal, but is limited. Once a diagnosis of MCI is made, it is important for the clinician to evaluate for reversible causes. At present time, there are no pharmacologic treatments proven to slow or cure progression of MCI to dementia; nonetheless, there is evidence that lifestyle modifications including diet, exercise, and cognitive stimulation may be effective...

BACKGROUND: Several recent reviews of the methods used to set research priorities have identified the CHNRI method (acronym derived from the "Child Health and Nutrition Research Initiative") as an approach that clearly became popular and widely used over the past decade. In this paper we review the first 50 examples of application of the CHNRI method, published between 2007 and 2016, and summarize the most important messages that emerged from those experiences. METHODS: We conducted a literature review to identify the first 50 examples of application of the CHNRI method in chronological order...

BACKGROUND AND PURPOSE: Alzheimer disease is the most common cause of dementia, and brain pathology appears years before symptoms are evident. Primary prevention through health promotion can incorporate lifestyle improvement across the lifespan. Risk factor assessment and identifying markers of disease might also trigger preventive measures needed for high-risk individuals and groups. SUMMARY OF KEY POINTS: Many potential risk factors are modifiable through exercise, and may be responsive to early intervention strategies to reduce the downward slope toward disability...

BACKGROUND: Physical activity is beneficial in people with dementia. As physical activity increases risk exposure for falls, safety concerns arise. Prior exercise trials in people with dementia have not measured physical activity. Falls in relation to exposure time rather than person-years as outcome measure has been promoted but not investigated in people with dementia. METHODS: Patients with mild to moderate dementia (n=110) were randomized to an intensive, progressive strength and functional training intervention or to a low-intensity group training for 12 weeks each...

The current absence of a disease-modifying treatment for Alzheimer's disease (AD) and vascular cognitive impairment and dementia (VCID) highlights the necessity for investigating the benefits of non-pharmacological approaches such as physical exercise (PE). Although evidence exists to support an association between regular PE and higher scores on cognitive function tests, and a slower rate of cognitive decline, there is no clear consensus on the underlying molecular mechanisms of the advantages of PE. This review seeks to summarize the positive effects of PE in human and animal studies while highlighting the vascular link between these benefits...

Cognitive impairment and dementia are common contributors to institutionalization and loss of quality of life in older people. Both type 2 diabetes mellitus (T2DM) and physical inactivity are prevalent and important modifiable risk factors for developing dementia. Physical activity is recommended in the management of T2DM, and there is growing evidence that exercise, a subgroup of physical activity, is also beneficial for maintaining and improving brain structure and function. This paper reviews the evidence for a benefit of exercise on T2DM related cognitive impairment and dementia...

Exercise-based therapy may improve health status for people with Mild Cognitive Impairment (MCI) or dementia but cannot work without adherence, which has proven difficult. This review aimed to evaluate strategies to support adherence among people with MCI or Dementia and was completed in Nottingham/UK in 2017. A narrative synthesis was used to investigate the effectiveness or usefulness of adherence support strategies. Fifteen adherence support strategies were used including theoretical underpinning (programmes based on behavior change theories), individual tailoring, worksheets and exercise booklets, goal setting, phone calls or reminders, newsletters, support to overcome exercise barriers, information, adaptation periods, individual supervision, support for clinicians, group setting, music, accelerometers/pedometers and emphasis on enjoyable activities...

In the present article, we provide a review of current knowledge regarding the role played by physical activity (PA) in preventing age-related cognitive decline and reducing risk of dementia. The cognitive benefits of PA are highlighted by epidemiological, neuroimaging and behavioral studies. Epidemiological studies identified PA as an influential lifestyle factor in predicting rates of cognitive decline. Individuals physically active from midlife show a reduced later risk of cognitive impairment. Neuroimaging studies documented attenuation of age-related brain atrophy, and also increase of gray matter and white matter of brain areas, including frontal and temporal lobes...

Age is characterized by chronic inflammation, leading to synaptic dysfunction and dementia because the clearance of protein waste is reduced. The clearance of proteins depends partly on the permeation of the blood-brain barrier (BBB) or on the exchange of water and soluble contents between the cerebrospinal fluid (CSF) and the interstitial fluid (ISF). A wealth of evidence indicates that physical exercise improves memory and cognition in neurodegenerative diseases during aging, such as Alzheimer's disease (AD), but the influence of physical training on glymphatic clearance, BBB permeability and neuroinflammation remains unclear...
