There is an area in the brain that will trigger an individual to drink when they are thirsty. When a person has dementia, this area of the brain may be affected. As a result, these individuals may feel parched, but they are not able to make the connection between taking a drink to relieve thirst.

Medications

Preventing Dehydration in Your Loved Ones

For those with loved ones who have dementia, there are preventative actions they can take to help keep their loved ones hydrated. It is important that individuals with dementia stay properly hydrated to avoid admission to hospital.

Make Water Easily Accessible

You can leave cups and jugs of water in various places throughout your loved one’s home. Try to place cups of water in your loved one’s favorite areas such as next to a favourite chair or on a nightstand near the bed.

Make Drinking Easy

There are some with dementia who have limited dexterity, so they will drink from a water bottle or easy-to-open top easier than they will from a cup. You can also have your loved one use cups with two handles and sturdy bases, which will prevent spills. One way straws are ideal for those with dementia because these straws will not return any fluid into the cups after an individual begins to suck from the straw.

Reminders and Notes
