Why staying hydrated is very important for people with dementia or Parkinson’s disease

Hydration—the act of keeping the body adequately supplied with water—is a cornerstone of good health. For the general population, drinking enough water is vital for various bodily functions, such as regulating temperature, maintaining blood pressure, and removing waste.

However, for patients with neurological conditions like dementia and Parkinson’s disease, staying hydrated is especially crucial, and yet often overlooked.

Dementia and Parkinson’s disease affect millions of people worldwide, impacting brain function and leading to a range of physical and cognitive impairments.

These conditions can make it difficult for patients to maintain adequate hydration due to various reasons, including reduced sensation of thirst, forgetfulness, or the physical inability to drink unassisted.

Research shows that dehydration can exacerbate symptoms of these neurological conditions. In dementia patients, inadequate hydration can lead to increased confusion, worsening cognition, and physical complications such as urinary tract infections and constipation.

Similarly, for those with Parkinson’s disease, not drinking enough water can worsen constipation, a common symptom, and contribute to the overall decline in physical function.

A study published in the “Journal of Gerontology” examined the effects of hydration on cognitive performance in elderly individuals, including those with dementia.

The research found that better hydration was associated with improved scores on cognitive tests. Although this study didn’t exclusively focus on dementia or Parkinson’s patients, it highlights the potential cognitive benefits of maintaining hydration.

Another aspect to consider is the impact of medications. Many patients with dementia and Parkinson’s are on medication regimens that can either contribute to dehydration or require adequate water intake to be effective.

For example, certain medications used to treat Parkinson’s disease can cause dry mouth or excessive sweating, both of which increase fluid needs.

Despite the clear links between hydration and health outcomes in these populations, challenges remain in ensuring adequate hydration.

Nursing home studies have pointed out that dehydration is a common issue among residents, particularly those with severe cognitive impairments. This is often due to a lack of regular monitoring of fluid intake and the inability of staff to recognize early signs of dehydration.

So, what can be done to help dementia and Parkinson’s patients stay hydrated? Simple strategies include:

  • Regularly offering fluids: Caregivers can offer water, juice, or other beverages consistently throughout the day, rather than waiting for the person to request them.
  • Enhancing fluid appeal: Sometimes, patients may be more inclined to drink if the beverages are flavored or served at a preferred temperature.
  • Using reminders and aids: Setting reminders to offer fluids and using special cups or straws that make drinking easier can be very helpful.
  • Monitoring fluid intake and output: Keeping track of how much a patient drinks and their urine output can help caregivers adjust fluid intake to meet their needs.

The benefits of maintaining proper hydration extend beyond just managing symptoms. Adequate hydration supports overall physical health, can improve mood and functionality, and contributes to a better quality of life.

In conclusion, while it might seem like a minor aspect of care, ensuring that patients with dementia and Parkinson’s disease stay adequately hydrated can have a significant impact on their health and well-being.

It’s a simple, yet effective way to support the management of these complex conditions, making it an essential part of daily care routines.
