When diabetes and memory loss come together, the main risks at home are missed or doubled medicines, skipped meals and low blood sugar that is hard to spot. A steady daily routine, a written plan from their diabetes team, and someone checking in at the times that matter can all help a parent stay safely at home.
To talk anything through with someone local, our Potters Bar team is on 01707 714 000.
How are diabetes and memory loss linked?
Diabetes UK explains that type 2 diabetes can increase the risk of dementia, although the risk varies from person to person. It is clear that living with diabetes does not mean someone will develop dementia.
The charity also notes two things that can look like memory loss but are not. First, a hypo, or low blood sugar, can cause confusion. Second, an infection can raise blood sugar and trigger delirium, which can be mistaken for dementia. So a sudden change always deserves a closer look.
Why diabetes and memory loss make the day harder to manage
Diabetes runs on routine, and memory loss quietly unpicks routines. Diabetes UK's guidance on dementia and diabetes lists the common problems:
- Forgetting a tablet, or taking it twice.
- Missing an insulin injection.
- Finding a blood sugar meter hard to read.
- Not recognising their own symptoms.
- Forgetting to eat, or eating again because they cannot remember eating.
- A higher risk of dehydration.
Medicines are often where families start, because a pill box can show at a glance what has been missed. We cover that side in more detail in our article on medication support at home in Potters Bar.
Spotting a hypo when memory is already affected
The NHS guide to low blood sugar lists signs such as hunger, sweating, shaking, dizziness, feeling anxious or irritable, tiredness, blurred vision and confusion. If blood sugar falls very low, a person can have a seizure or become unconscious.
The NHS says hypos mainly affect people who take insulin or certain diabetes tablets, such as gliclazide or glimepiride. So it is worth knowing whether your parent takes any of these.
The difficulty is that several hypo signs look like a bad memory day. For that reason, Diabetes UK advises that if in doubt, blood sugar should be checked. In practice, it helps to ask the diabetes team for a written hypo plan, and to make sure everyone who visits knows where it is kept.
When is it an emergency?
The NHS says to call 999 if you think someone has very low blood sugar and they are not responding normally or are unconscious, and glucagon is not available, has not worked within 10 minutes, or they have been drinking alcohol.
Building a routine that holds
Diabetes UK's suggestions are practical and easy to start:
- Meals, medicines and blood sugar checks at the same times each day.
- A pill organiser, blister packs or reminders for tablets.
- Asking the diabetes team whether the routine could be made simpler.
- Small, frequent meals and finger foods, eaten with company where possible.
- Going to diabetes and GP appointments together.
The charity is also clear that nobody should start, stop or change a medicine because of dementia risk alone. Any concerns go to the GP or the diabetes team.
What should families do about sudden confusion?
Diabetes UK says sudden confusion or a change in behaviour may need urgent medical attention. It could be a hypo, high blood sugar, an infection or delirium.
Therefore, it helps to know what "normal" looks like for your parent. A short daily note of meals, drinks and mood makes a sudden change easier to spot and easier to describe to a GP or NHS 111.
What our carers do, and what they do not
Our diabetes support at home is built around prompting, meals, checks and escalation. In practice, carers can:
- Prompt medicines at the agreed times, as set out in the care plan.
- Prepare meals and snacks, and encourage regular drinks.
- Prompt the blood sugar checks the diabetes team has asked for, and write the results down.
- Notice signs of a hypo or a change in the person, and escalate to the family, GP, NHS 111 or 999.
Our carers do not give insulin injections and never change doses. Where memory loss is part of a wider dementia picture, our dementia care in Potters Bar article explains how visits fit around the working day.
Frequently asked questions
Can diabetes itself cause memory problems?
Diabetes UK explains that high blood sugar can damage the small blood vessels supplying the brain, which may lead to memory problems. Hypos and infections can also cause confusion for a while. The GP is the right person to look into new memory changes.
Would a glucose monitor make things easier?
It may help some people, according to Diabetes UK. However, the charity notes that a simpler routine may suit someone better if memory or dexterity is affected. That choice belongs with your parent and their diabetes team.
My mum keeps eating sweet things. Should I hide them?
A preference for sugary food is one of the changes Diabetes UK describes in people with dementia. Rather than removing favourite foods, talk to the diabetes team or a dietitian about how to fit them in safely.
Who can I call for diabetes advice?
Diabetes UK runs a helpline on 0345 123 2399. For anything about your parent's own treatment, contact their GP practice or diabetes nurse.
