Rehydrate for better memory -

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.

Pregnant women need 10 cups each day and women who breastfeed should drink You've probably heard that the right diet can stave off memory loss. Eating a combination of brain-friendly foods such as leafy greens, berries, fish, nuts and olive oil is thought to delay age-related thinking problems and guard against Alzheimer's disease. Is it possible, though, to increase your short-term memory through good nutrition? According to a new study from Britain, if you drink plenty of water, the answer is yes. It seems that being even just slightly dehydrated can impair attention and memory. For the study , published recently in the American Journal of Clinical Nutrition, researchers subjected undergraduate students to a temperature of 30 C for four hours, over three occasions, during which they either did or did not drink millilitres of water. All performed a battery of memory tests. Participants' body temperatures and body weights were measured and urine samples were collected at the beginning and throughout the study. After three hours into the experiment, a greater loss of body weight — as little as 0. Those who weren't allowed to drink water found the tests more difficult to perform than did those who hydrated during study. You don't have to sweat it out in hot, humid weather to lose less than 1 per cent of your body weight. Such a minor degree of dehydration can easily occur during a normal day — even a cool, fall day — if you don't drink water often enough. Healthy adults living in temperate climates need 12 to 13 cups men and 9 cups women of water each day. Pregnant women need 10 cups of water each day and women who breastfeed should drink 13 cups. All beverages — excluding alcoholic drinks — count toward your daily water requirement. Keep in mind, though, that the study didn't distinguish between the role of mild dehydration and the response to heat on memory. The researchers also didn't measure habitual water, caffeine and alcohol intake, factors that could have influenced participants' hydration status at the onset of the study. Even so, previous research has shown that being mildly dehydrated impaired performance in tasks that require attention, memory and psychomotor skills i. brain-muscle co-ordination. It even reduced mood, a consequence that can also affect memory. Water accounts for 55 to 60 per cent of body mass; hydration status plays an important role in all body functions and in many chronic diseases. It's not surprising, then, that drinking too little water may hinder optional brain function. In fact, a few studies have shown that cognitive performance in schoolchildren improves when they're given a drink. Over all, however, the evidence that certain foods and nutrients can increase your memory power is limited. Much of it is observational, which doesn't prove cause and effect. Findings from randomized clinical trials, the scientific gold standard, have been inconsistent.

One more study in found that the dehydration state induced by exercise without replacing fluid losses reduced total brain volume among 10 sportsmen There was one study that investigated the changes in brain structure under the dehydration state using voxel-based morphology, and it showed that there were associations between the decrease in gray matter GM and white matter WM volume and the dehydrated state in various brain regions In a study conducted among nine physically active adult participants aged 24 years old, it was found that a dehydration state induced by exercise and heat stress with 2.

In a long-term hydration experiment, six healthy young adults 25 years old were recruited, and a dehydration state was induced in two days by water restriction to mL water per day Related studies are few, related studies has been summarized in Supplementary Table 1.

It is meaningful to conduct further studies to explore the effects of the hydration state on the brain structure and functions using the method of brain magnetic resonance imaging. The purposes of this study are, first, to analyze the effects of slowly progressive dehydration after 36 h of water deprivation on brain regional density and homogeneity using the method of MRI and, second, to explore the effects of rehydration after an adequate amount of water supplementation on brain regional density and homogeneity among healthy young adults in China.

The results of MRI in this study provide more evidence about the importance of hydration. It is also meaningful to bring attention to drinking an adequate amount of water and maintaining an optimal hydration state.

Twelve healthy male young adults were recruited from one college in Cangzhou, China. The inclusion criteria were as follows: the age of participants was between 18 and 25 years; the participants were in a healthy state.

This sample size was also consistent with previous studies in which the sample size was in the range of The study protocol and instruments were reviewed and approved by the Ethical Review Committee of Chinese Nutrition Society on November 10, The code of identification is CNS The study was conducted in accordance with the guidelines of the Declaration of Helsinki.

Prior to the conduction of the study, all participants read and signed informed consent voluntarily. The study procedure of the self-control trial is shown in Figure 1. During the study, volunteers were asked to not perform vigorous-intensity physical activities e. All participants were monitored by research supervisors and investigators.

Three MRI tests were performed, including test 1 under baseline state, test 2 under dehydration state caused by 36 hours of water deprivation, and test 3 under rehydration state after water supplementation. All tests were conducted in Cangzhou Central Hospital.

Figure 1. Procedure of the study. H is the abbreviation for height; W is weight; BP is blood pressure; VAS is visual analog scales; MRI is magnetic resonance imaging.

Day 1: All participants fasted overnight from p. and were told to sleep no later than 11 p. They were required to not urinate until awaking on day 2. Day 2: First, urine samples were collected at a. in the morning using a sterile urine sample accumulator and then sent to be tested by lab technicians in the hospital.

Cubital venous blood was collected and sent to determine the blood osmolality and blood glucose. Body measurement and blood pressure were also conducted. Visual analog scales on thirst were conducted, and brain magnetic resonance imaging MRI was performed as baseline test 1.

After test 1 under the baseline state, participants could eat and drink. After p. Day 3: Participants could not drink any fluid and lasted for 24 h from a. on day 3. Three specified solid meals were supplied to participants by a researcher at a.

No other food was eaten. Fluid intake from foods was assessed using methods of weighing, duplicate portion, and laboratory analysis. Each urine sample was collected by the participants and then sent for evaluation of the 24 h urine volume by researchers.

The urine osmolality of each urine sample was also determined. Participants were required to sleep no later than 11 p. and to not urinate until awaking on day 4. Day 4: At a. Brain magnetic resonance imaging was performed under dehydration state caused by 36 h of water deprivation. Participants drank 1, mL of purified water in fifteen minutes at a.

and were required to drink mL every 5 min. After resting for an hour, test 3 under rehydration state was performed. Brain magnetic resonance imaging was performed under rehydration state after water supplementation.

The temperature and humidity of the living environment among participants during these days were measured and noted. In the whole process of the study, participants who failed to meet these requirements needed to let investigators know.

Finally, all participants finished the study, and no one failed to meet the requirements. Weighing, duplicate portion, and laboratory analysis methods were used to assess water intake from foods.

See 23 for the specific steps and calculation methods. Wearing light clothing and no footwear, height H was measured twice with 0.

Blood pressure BP was measured twice with 2 mmHg accuracy by a nurse with electronic sphygmomanometer HEM; Omrom, Dalian, Liaoning, China. Two measurements were conducted after 2 min intervals. Starting with the second voiding on day 3 and ending with the first voiding on day 4, all urine samples were collected as total 24 h urine volume on day 3.

Urine volume was measured with the accuracy 0. Additionally, urine osmolality was tested using an osmotic pressure molar concentration meter SMC 30C; Tianhe, Tianjin, China. Cubital venous blood was also used to test osmolality and glucose of blood.

Blood osmolality was tested with an osmotic pressure molar concentration meter SMC 30C; Tianhe, Tianjin, China. Blood glucose was tested with an automatic biochemical analyzer Cobas C; Roche, Basel, Switzerland.

Visual analog scales VAS are a self-rated 10 cm line designed to quantitatively measure the subjective feeling of thirst Participants were required to draw a vertical line corresponding to their degree of thirst.

The range of scores for thirst varied between 0 and Magnetic resonance imaging scans were administered on a 3-teslas SIGNA HDx scanner Discovery MR , General Electric; Milwaukee, WI. Participants laid flat on the scanning stage.

The heads of participants were placed centrally, the mandibular was adducted, and intracranial anterior commissure and posterior commissure AC-PC line were as parallel as possible to the axial line. If necessary, the localization of head was realigned. Participants were required to stay awake, to close their eyes, to breathe quietly, and to plug their ears with a rubber stopper to reduce noise interference.

Structural MRI: Based on the scout images, structural MRI was performed in parallel with the AC-PC line. The temperature and humidity indoor and outdoor were recorded at a. with a temperature hygrometer by researchers during the experiment.

Data processing of structural MRI was carried out on the network platform of MATLAB a, MathWorks, Natick, MA, USA.

VBM voxel-based morphometry of the T1 image was analyzed using the neuroimaging computing software SPM8 Statistical Parametric Mapping 1 with toolboxes of VBM8 and DARTEL. The process mainly included the following steps: a correction, in which the T1 images were reoriented and calibrated to ensure that the anterior commissure was the origin 0,0,0 ; b segmentation, in which the T1 images after the original point correction were segmented into GM gray matter , WM white matter , and CSF cerebrospinal fluid voxel fraction images; c template generation, in which the group template was generated using the DARTEL method 25 and iterated several times; d normalization, in which all images of participants were spatially normalized by registration to the Montreal Neurological Institute brain template MNI and the voxel size after registration was 1.

The images for the location of brain regions with statistical differences between the two groups were presented by conventional axial bitmap using Software MRICron 2 and BrainNet Viewer 3. Data processing of fMRI was also carried out on the platform of MATLAB.

SPM8 software toolkit was used for data preprocessing. SAS 9. The mean and standard deviation SD were used to describe the quantitative parameters; count data hydration state were presented as n percentage.

The differences in brain gray matter, brain white matter, and cerebrospinal fluid among brain areas were calculated using SPM8software. The method of one-way analysis of variance ANOVA with replicate measures was used to compare the quantitative parameters among test 1, test 2, and test 3.

Then the obtained differential brain regions are subjected to multiple comparison correction FDR corrected. Finally, the differential brain regions corrected by multiple comparison were used as a mask for post hoc test. The significance levels were set at 0. The classification data such as the distribution of hydration state were compared using the method of Chi-square test.

When the conditions were not suitable for Chi-square test, such as the expected frequency was less than 5, Fisher exact test was used for comparison and analysis. Significance levels were set at 0. All participants finished the study.

The average age of these 12 male young adults was The height, weight, BMI, and systolic and diastolic pressures under test 1 were However, there was statistical significance in blood glucose when compared between test 1, test 2, and test 3 4. The average temperature of day 1 to 4 was Among 12 participants, the average water intake from food was ± ml.

The 24 h urine volume of participants was ± ml. The void number was 5 ± 2 on day 3 Supplementary Table 3. Statistically, significance was found in blood and urine osmolality and the thirst when compared among three tests.

Compared with test 2, less proportion of dehydration was found in test 3 vs 8. Table 2.

However, studies about the effects of hydration on brain structure and the connectivity of brain nodes among healthy adults are scarcely reported.

In the study, the effects of hydration on brain regional density and homogeneity were measured using the method of MRI. It was shown that dehydration increased cerebrospinal fluid density. Rehydration caused an extensive increase in gray matter density and white matter density in some specific brain regions.

As one indicator of the connectivity of brain nodes, the ReHo value was also affected by the state of hydration. A few related studies have been conducted in some other countries.

The results of one study suggested that dehydration induced by a 16 hour period of fluid restriction reduced the total brain volume, and brain volume was restored following rehydration In a study conducted among sight-active men participants, it was found that dehydration with 2.

In two other related studies, the results showed that ventricular volume changes under a hypohydration state in terms of 1. In one study, MRI scans were also conducted to explore the mechanisms of an acute dehydration state among participants, and it was found that there was an expansion of the ventricular system with the largest change appearance in the left lateral ventricle, which may induce the short-term changes of cognitive performances controlled by the brain.

In another study with the method of brain MRI scans, it was suggested that blood-oxygen-level-dependent BOLD responses in the fronto-parietal increased and lateral ventricle were enlarged in acute dehydration induced by a thermal exercise protocol However, in a study with twenty healthy volunteers, brain MRIs were scanned in three conditions: a baseline scan, a scan after hydration when consuming 3L of water over 12 h, and a scan after dehydration after overnight fasting for 9 h.

Additionally, it was found that brain volume and brain total water content were not substantially affected The ReHo value of regional homogeneity was usually used to evaluate spontaneous neural activity during the resting state and can be used to explore the connectivity of brain nodes and cognitive performances One study demonstrated that changes in ReHo were correlated with changes in cognitive performance in some circumstances The mechanism of the effects of hydration on brain structure and the connectivity of brain nodes may be explained by the following reasons.

Dehydration is usually accompanied by hypovolaemia, which may cause an increase in the ventricular system volume and a reduction in brain volume 19 , 28 , 33 , Serum osmolality induced by acute dehydration could produce an osmotic gradient, resulting in an increased diffusion of intracellular water stores into extracellular space.

The changes cause shrinkage of cells, particularly astrocytes, which have a vital role in the transport of water, and thus leads to ventricular system expansion Adverse health effects and related symptoms of mild and moderate dehydration in daily life often do not receive enough attention.

In this study, the changes in brain regional density and homogeneity under different hydration states were discovered. This study has some strengths and weaknesses. Referring to the method of inducing dehydration, dehydration can be induced by heat stress, fluid restriction, exercise, diuretics, or combinations of the above methods in current studies.

However, some methods of inducing dehydration may affect brain regional density and homogeneity, such as heat stress and exercise. In this study, water deprivation and supplementation were used to induce changes in hydration states among participants, which may be more meaningful in exploring the effects of hydration on brain structures clearly.

In addition, it is also very important to ensure the quality control during water deprivation. The osmolality of urine during the period of water deprivation was continuously monitored to explore the changing trend of hydration state and to verify the adherence of participants, which showed that the study had restricted and high quality control.

In some studies, the objective physiological and biochemical indexes are not used to monitor the quality control during water deprivation.

In consideration of weakness, gender differences and the effects of long-term water intervention on brain regional density and homogeneity were not studied. In addition, this is a pilot self-control trial to explore the effects of dehydration and rehydration on brain regional density and homogeneity.

Randomized controlled design studies could obtain more effective results and reveal scientifically effects of hydration state on brain structure and function more clearly and accurately.

In this study, only brain regional density and homogeneity was analyzed. Some other indexed such as brain volume and blood oxygen level dependent were not analyzed, more comprehensive indexes would be helpful to explore the effective of hydration on brain structure and function.

Based on this pilot self-control trial, more high-quality research and analysis can be carried out in the future. In summary, dehydration state increased cerebrospinal fluid density, decreased brain regional homogeneity. Rehydration state increased brain gray matter and white matter density widespreadly, and in-creased brain regional homogeneity.

Maintaining a normal hydration state through sufficient water intake is helpful in maintaining brain regional density and homogeneity.

As we get older, our ability to recognize thirst declines, much as our taste buds decrease as we age. Dehydration is one of the most frequent causes of hospitalization of elderly Canadians.

Individuals with moderate dementia often have difficulty remembering the mechanics of how to drink, such as turning on the faucet or even how to get fluid into a glass.

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.

Of course we need water mrmory survive. That seems Rehydrate for better memory obvious. But why? What does hydration actuall y do for us? More than you may think! We rely on our brains to function at maximum potential.
