People with dementia may become dehydrated if they are unable to communicate or recognise that they are thirsty, or if they forget to drink. This can lead to headaches, increased confusion, urinary tract infection and constipation. These can make the symptoms of dementia worse.

​

While a healthy, balanced diet is important, in the later stages of dementia the most important thing is making sure the person with dementia takes on nutrition, and a higher-calorie diet may be appropriate. A dietitian can give you advice on what is best in a particular situation.
