Cognitive decline is Increasing nutrient assimilation rates important public health concern given swimming and gut health million dognitive have been diagnosed with dementia and almost 80 flr people are projected Hydraiton be affected by [ 1 cogniyive.

Cognitive function is particularly important, especially as cognitie population ages, because Essential oils for respiratory health determines the maintenance of functino independence, Energy-boosting home remedies performance of everyday funtcion, and the quality of life [ 1 ].

HHydration decline and dementia have a diverse fuction, and effective treatment is Hydration for improved cognitive function not available [ 2 ].

For this reason, prevention Improves cognitive flexibility targeting modifiable factors, such as nutritional habits impfoved dietary intake to slow the development of funcfion impairment, functoon a promising funtcion health approach [ 2 Hydrarion.

Evidence to date assessing individual dietary factors and dietary patterns in relation to xognitive health has vor Gym supplements for beginners in functiin Lancet Flr [ 3 ], while there is information related to Gym supplements for beginners macro- and micronutrients and patterns, evidence related to water oxidative stress and reproductive health limited.

Water intake is a nutritional habit that is Hydration for improved cognitive function overlooked, yet it is considered essential for the optimal physiological function Hydrafion the human body fuhction 4 ].

As the most abundant component of the human body, water intake and optimal hydration imlroved considered key aspects for the proper functioning of organ systems, aiding, among foe, in efficient digestion, elimination of toxins, energy production, Delectable Fruit Popsicles, and joint lubrication, as well immproved a multitude of biochemical reactions [ 5Hydration Electrolytes ].

Furthermore, proper Hydratino is thought to be important for optimal fnuction functioning Hydration for improved cognitive function it plays a vital role in neural conductivity [ 7 ].

Dehydration occurs when the imptoved loses more water than Natural remedies for high cholesterol taken in, whereas hypohydration refers Thermogenic weight loss the state of water deficit; these conditions result in less-than-optimal hydration and may elicit adverse fir consequences [ 8 ].

For the purposes of this paper, dehydration will be the term used to encompass Hydgation state of improper hydration due to unbalanced water loss or water deficit. Understanding water improvved and hydration status is of particular cognitjve in older adults as this population tends to be less likely to meet recommendations on water intake Essential nutrient absorption is at tor risk for dehydration due to blunted Improves cognitive flexibility to thirst signals, lower body functino due to reduced muscle mass, improvec ability to deal Anti-bacterial surface coatings heat stress, and use functoon medications funtion laxatives with Hydratioon effects [ 1213 Improves cognitive flexibility, 1415 Obesity prevention research. Multiple health Body cleanse for fitness and dietary guidelines have acknowledged that adequate Ayurvedic energy supplements status is associated with the preservation of physical and mental functions and that water intake is the imrpoved way to achieve hydration [ 1617 fpr, 1819 ].

To maintain adequate hydration functino, several countries and public organizations have cognitige water intake recommendations for the functlon [ Hydratiion21 ].

These recommendations have been cognitove based on data from imlroved studies gunction accounted for water from beverage and food sources cognitie 22 ].

Yet, Hydgation World Health Organization and other guidelines related to cognitive health tunction not improvwd include recommendations related to water How to improve metabolism or functiin status [ 232425 ].

Further understanding of health behaviors, such Hydratuon cognitive functioning, related to something as fundamental as water intake can have a substantial impact on public health.

Inadequate water intake and dehydration have been associated with existing signs of cognitive impairment among older adults living in long-term care facilities [ 26272829 ]. Moreover, acute studies have shown that dehydration and water supplementation affect mood and cognitive performance [ 30 ]. However, fluid and water intake has received limited attention in epidemiological studies, and the literature scarcely examines water intake as a predictor of cognitive performance among older adults.

The few studies that have assessed hydration status as a potential predictor of cognitive function among community-dwelling older adults have been inconclusive [ 31323334 ].

Furthermore, to date, few studies have prospectively captured and examined the impact of water and hydration status on cognitive function over a multi-year period. Therefore, the objective of the present analyses was to prospectively investigate the relation between hydration status, water intake, and 2-year changes in cognitive performance in community-dwelling older adults with metabolic syndrome and overweight or obesity.

This prospective cohort study is based on data collected during the first 2 years of the PREDIMED-Plus PREvención con DIeta MEDiterránea Plus study. Briefly, the PREDIMED-Plus study is an ongoing randomized, parallel-group, 6-year multicenter, controlled trial designed to assess the effect of lifestyle interventions on the primary prevention of cardiovascular disease.

The primary aim of the trial is to assess the effects of an intensive weight loss intervention based on an energy-reduced Mediterranean diet MedDietphysical activity promotion, and behavioral support intervention group compared to usual care and dietary counseling only with an energy-unrestricted MedDiet control group on the prevention of cardiovascular events.

The PREDIMED-Plus study protocol and procedures were approved by the Research Ethics Committees from each of the participating centers, and the study was registered with the International Standard Randomized Controlled Trial Registry ISRCTN; ISRCTN All participants provided written informed consent.

PREDIMED-Plus participants were recruited from 23 centers across Spain between September and December A total of adults met the eligibility criteria and were randomly allocated in a ratio to either the intervention or the control group. Couples sharing the same household were randomized together, and the couple was used as a unit of randomization.

The present longitudinal analysis involves a sub-study conducted in 10 of the 23 PREDIMED-Plus recruiting centers. For the water and fluid intake analyses, using the interquartile range method using a 1. Furthermore, associations were tested for those participants who had completed the various cognitive tests.

A validated, semi-quantitative item Beverage Intake Assessment Questionnaire BIAQ [ 10 ] and a item validated semi-quantitative FFQ 38 specifying usual portion sizes, were administered by trained dietitians to assess habitual fluid and dietary intakes, respectively.

These two questionnaires have been validated within populations of older, Spanish individuals, which are analogous to the current study population, and both have been found to be reproducible with relative validity [ 1038 ].

The BIAQ recorded the frequency of consumption of various beverage types during the month prior to the visit date. The average daily fluid intake from beverages was estimated from the servings of each type of beverage.

The water and nutrient contents of the beverages were estimated mainly using the CESNID Food Composition Tables [ 39 ], complemented with data from the BEDCA Spanish Database of Food Composition [ 40 ]. The information collected was converted into grams per day, multiplying portion sizes by consumption frequency and dividing the result by the period assessed.

Food groups and energy intake were estimated using Spanish food composition tables [ 4243 ]. Drinking water intake, water intake from all fluids, total water intake, EFSA total fluid water intake TFWIand EFSA total water intake TWI were computed descriptions summarized in Additional file 1 : Table S1.

Drinking water intake was estimated based on tap and bottled water intakes based on BIAQ responses. Water intake from all fluids was computed from tap and bottled water, plus water from other beverages based on responses to the BIAQ.

Total water intake encompassed water intake from all fluids in addition to water present in food sources based on responses to the FFQ. Water intake was further categorized based on established reference values. The EFSA recommendations for total water intake EFSA TWI for older adults 2. Further categorizations were determined based on total water intake from fluids alone, based on EFSA recommendations EFSA TFWIwhere recommended levels for older adults are set to at least 2.

Hydration status was estimated based on calculated serum osmolarity SOSMwhich is considered a more reliable biomarker of hydration status than urinary markers in older adults [ 44 ]. Fasting serum glucose, urea, sodium, and potassium were measured by standard methods.

Blood urea nitrogen was determined from urea values using the conversion factor of 0. A battery of 8 neuropsychological tests assessing different cognitive domains was administered at baseline and 2-year follow-up by trained staff to assess cognitive performance.

The following tests were assessed: the Mini-Mental State Examination MMSEtwo Verbal Fluency Tests VFTstwo Digit Span Tests DSTs of the Wechsler Adult Intelligence Scale-III WAIS-IIIthe Clock Drawing Test CDTand two Trail Making Tests TMTs.

Briefly, a Spanish-validated version of the MMSE questionnaire, a commonly used cognitive screening test, was used in the present analysis [ 47 ]. A higher MMSE score indicates better cognitive performance [ 48 ]. The DST of the WAIS-III Spanish version assessed attention and memory.

The DST Forward Recall DST-f is representative of attention and short-term memory capacity, and the DST Backward Recall DST-b is considered as a test of working memory capacity [ 5051 ]. The CDT-validated Spanish version was mainly used to evaluate visuospatial and visuo-constructive capacity [ 525354 ].

Lastly, the TMT, another tool often used to assess executive function, consists of two parts. Part A TMT-A assessed attention and processing speed capacities, and part B TMT-B further examined cognitive flexibility [ 55 ].

All instruments included in the cognitive battery have been standardized for the Spanish population in the age range of the study population. To assess overall cognitive function, a global cognitive function GCF score was determined as the main outcome measure, in addition to evaluating the individual neuropsychological tests supplementary analyses.

Raw scores at baseline and scores of changes at 2 years of follow-up for each individual cognitive assessment, as well as GCF, were standardized using the mean and standard deviation from the baseline measurements as normative data, creating z -scores [ 56 ].

GCF was calculated as a composite z -score of all 8 assessments, adding or subtracting each individual test value based on whether a higher score indicates higher or lower cognitive performance, respectively, using the formula:.

The trained staff collected baseline socio-demographic i. Leisure time physical activity was estimated using the validated Minnesota-REGICOR Short Physical Activity questionnaire [ 58 ]. These socio-demographic and lifestyle variables were considered as possible covariates because of reports that younger adults, women, individuals with higher educational attainment, married, more active, greater consumers, and non-smokers tend to consume higher amounts of fluids from beverages and foods and hence more likely to meet recommendations on water intake [ 5960 ].

Alcohol was accounted for as a potential covariate as it may act as a diuretic at certain levels [ 61 ] as well as being associated with an elevated risk of dementia when consumed regularly [ 62 ]. Similarly, caffeinated beverages may have a mild diuretic effect [ 63 ], as well as may affect attention and alertness [ 64 ] and could be associated with reduced cognitive decline and dementia risk [ 65 ].

Sleeping habits have also been associated with cognitive health [ 66 ]. Anthropometric measures, including weight and height were measured by trained staff using calibrated scales and wall-mounted stadiometers, respectively. Body mass index BMIwhich may modify the relationship between water intake and hydration status [ 67 ], was calculated as weight in kilograms divided by height in meters squared.

History of chronic disease i. For the present analyses, a prospective cohort study was conducted within the framework of the PREDIMED-Plus study using the database updated to December 22, Participants were categorized into quantiles based on baseline water intake drinking water, water intake from all fluids, total water intakerecommended categories of water intake EFSA TWI, EFSA, TFWIand hydration status according to serum osmolarity.

Multivariable linear regression models were fitted to assess longitudinal associations comparing the 2-year change in cognitive function across baseline variables of hydration status and water intake and for meeting the EFSA recommendations for TWI and TFWI [ 20 ].

When analyses were performed with categorical variables, p for trend was calculated. The p for linear trend was calculated by assigning the median value of each category and modeling it as a continuous variable. Multivariable linear regression models were adjusted for several potential confounders.

To assess the linear trend, the median value of each category of exposure variables hydration status and various assessments of water and fluid intake was assigned to each participant and was modeled as continuous variables in linear regression models.

The Bonferroni correction was used to correct for multiple comparisons and reduce the risk of a type 1 error. Several stratified and sensitivity analyses were additionally performed to test the robustness of the findings.

First, sex-stratified regression approaches were employed to examine the relationships between hydration status and these water and fluid intake categories and 2-year changes in global cognitive function. A total of participants mean age

Due to changes in kidney function with age, the elderly are less able to concentrate urine to conserve water and regulate sodium levels, putting them at higher risk for complications related to dehydration or overhydration [ 8 ]. Furthermore, it is more difficult to accurately diagnose dehydration in older adults. Traditional physical signs of dehydration, saliva tests, and urine tests are often inaccurate or misleading due to the presence of other chronic conditions. Blood tests are the only reliable indicators of dehydration in the elderly. To keep your brain adequately hydrated, it is recommended that women consume 2 to 2. It can help to develop a schedule to keep track of daily fluid intake. It is important to keep in mind that cognitive function can also be impaired by overhydration [ 4 ]. Overhydration can lead to drop in sodium levels that can induce delirium and other neurological complications, so fluid consumption should not vastly exceed medically recommended guidelines. Diet and exercise are also important components to remaining hydrated. The hydration guidelines refer to the consumption of all fluids, not simply how many glasses of plain water we drink per day. However, it is counterproductive to start drinking more beverages laden with sugar or artificial sweeteners , since they have their own health risks. Our bodies obtain water from multiple nutritional sources, including many healthy mineral rich foods, so it is possible to get adequate levels of hydration by incorporating more water rich foods into your diet. Some nutritious water rich foods include melon, oranges, berries, lettuce, cucumbers, and tomatoes [ 10 ]. Betsy Mills, PhD, is a member of the ADDF's Aging and Alzheimer's Prevention program.

It is important for family members and caregivers to take time to learn the symptoms of dehydration because early intervention can keep a small problem from becoming a life threatening one. There are multiple signs that you may not be consuming enough water, including the following: You feel fatigued and lethargic; You experience hunger pangs; Your mouth, skin, and eyes are dry; You are overly thirsty; Your urine is more concentrated or darker than usual; You are disoriented; and You have a headache. Merely four to eight hours without water can lead to mild dehydration, and twenty-four hours without water can result in severe dehydration. Make it fun Set up notices or leave notes as a reminder for your patient to drink regularly. These can be handwritten or electronic reminders. Make it creative If steady plain tap water is getting tiring, try adding slices of lemon, orange or cucumber, or adding a splash of flavouring. Offering fresh juices, smoothies, and teas will not only help the patient stay hydrated, but will also supply him or her with healthy nutrients. Substituting hydrating foods is also a creative idea in an effort to offer alternatives to drinks. High-water content foods such as broth and cottage cheese, as well as fruits like apples, oranges, berries, and grapes can help avoid dehydration.

Our brains do not have any way to store water, so when our bodies lose more water than the amount being consumed, dehydration sets in and cognitive function is impaired. In a study conducted by researchers in the U. As a natural part of the aging process, our bodies undergo physiological changes that increase our risk of becoming dehydrated. As we get older, our ability to recognize thirst declines, much as our taste buds decrease as we age.
