Dehydration and delirium--not a simple relationship.
Simple interventions (family visits, familiar objects, clocks) may help to the pneumonia or dehydration) will help the delirium to improve more quickly. the date is, who you are (reminding them of your relationship to them).

Closing this knowledge gap will reduce delirium risk because inadequate fluid intake is relatively easy to.

Poor access to fluids or needing help to drink may limit intake. Many drink water only when taking medication. Living in over-heated indoor spaces dehydrates even without sweating. Older adults have decreased muscle mass and increased fat; because 75 percent of body water is stored in muscle, seniors have less capacity to store water.
Women have more body fat than men at any age, so older women are at even higher risk of dehydration. Due to decreased kidney function, older adults cannot conserve fluids as well as younger people.
How do you know if you are drinking enough? An older adult, their home caregiver or family member can take simple steps daily to check hydration status. First, thirst should not be experienced at any time. Second, urine should be colorless or straw colored, and odorless. Being familiar with a urine color chart is good practice for all ages and critical for older adults to avoid dehydration.
First morning urine should not be dark, and urination should occur every two to four hours during waking hours. Some medications and foods such as asparagus give urine an odor, but normally urine should not smell. Increase daily fluid intake, especially water! At least half of your daily fluids should be water. Milk, vegetable or fruit juice, and soup are also healthy fluid choices. Carbonated and caffeinated drinks should be limited due to their diuretic effect.
The body needs water to filter alcoholic beverages from the body. Therefore, increased water consumption is needed overall as well as to balance the dehydrating effects of unhealthy drinks. Drinking healthy fluids is as important as eating healthy foods. Family members and home caregivers should: Family should report poor eating or drinking to the primary care provider so interventions can be initiated to prevent dehydration and its consequences.
Although a common clinical problem, we have no easy method to detect it early and possibly prevent hospital admission, delirium, and even death. In this issue, Culp and colleagues report the results of an analysis of bioimpedance and other hydration parameters as risk factors for delirium in rural nursing home residents 7.
They found no relationship between bioimpedance measurements of hydration and delirium, but there was a statistically significant relationship between blood urea nitrogen: This result is disappointing for anyone who might have hoped for a sensitive test from a practicable instrument. Experience with bioimpedance in elderly people is comparatively limited especially in dynamic scenarios and when there may be electrolyte disturbances 1.
In addition, the bioimpedance measurements may have influenced the behavior of the nurses or even the patients, by consciously or subconsciously resulting in increased fluid intake.
Although this effect might have been detected had fluid balance charts been kept, fluid intake records can be unreliable in nursing homes, and have their own potential for inducing an observation effect. As difficult as the study of dehydration might be, the study of delirium can be even more complicated. At present, delirium remains a clinical diagnosis, without an adequately sensitive and specific biological marker.
Delirium - Symptoms and causes - Mayo Clinic
The authors usefully employed several measures to yield a reproducible estimate of whether delirium was present. Their counting as a second episode of delirium recurrence of symptoms after only 24 hours of cognitive stability might overestimate the incidence of delirium. Still, their protocol offers a practicable means to detect delirium in studies in which not everyone can be seen by a clinician expert in delirium diagnosis.
Despite these few reservations, the study by Culp and colleagues raises many fascinating questions 7.
Is bioimpedance a practical method to detect dehydration in older people, or is it confounded by factors, such as changes in body composition and electrolyte balance, that accompany frailty?
How well does it compare with other methods? Delirium is not a diagnosis but a multifactorial syndrome and a manifestation of frailty, itself a multiply-determined dynamic state 8. Does this study indicate that delirium is not as strongly associated with dehydration as is commonly thought?
