It could be more than just getting older

Have you noticed changes in your memory or behavior? Living with type 2 diabetes, obesity, or other chronic diseases puts you at a risk of this being something more serious than just forgetfulness.

It might be more than getting older

We all have those moments - walking into a room and forgetting why, or misplacing our car keys. Maybe you've always had a sharp memory, but lately, something feels different. You've noticed it. 

But what if those lapses aren't just signs of getting older? What if there’s a deeper connection, something that starts in the body before it affects the mind? 

What to ask your doctor about changes in behaviour 

Small changes in memory and behaviour are worth talking about. These questions can help you get the conversation started with your doctor. 

The hidden link between your health and your brain 

Forgetfulness can certainly come with age and a busy life, but that's not always the full story.

There may be an underlying link between cognitive issues - like changes in memory, language, and behavior - and chronic conditions like obesity and type 2 diabetes. This is a connection many people don't know about. 

Living with obesity and type 2 diabetes can increase your risk of developing Alzheimer’s disease, the most common form of dementia, later in life. If you’ve noticed  changes, especially in these areas, it might be worth investigating. 




Knowing the facts to take action

When chronic diseases like obesity and type 2 diabetes aren't managed, they can affect your brain function.  

The impact of obesity on cognitive health


  • If you live with obesity and are between the ages of 35 and 65, your risk of developing dementia increases by about 30%. 
  • Obesity raises the risk of other dementia risk factors, such as high blood pressure and type 2 diabetes, by 2 to 3 times. 
  • People with obesity may also face a higher risk of depression, low activity, and limited social contact—all factors linked to dementia. 

The impact of type 2 diabetes on cognitive health


  • Type 2 diabetes can increase the risk of Alzheimer’s by at least two-fold. 
  • Living with diabetes for many years can increase your risk of dementia.
  • People with diabetes are more likely to have high blood pressure, high cholesterol, and obesity—all of which are linked to dementia. 

Addressing the risk factors may prevent or delay nearly half of all dementia cases.

Alzheimer's disease - risk factors

Fourteen risk factors have been identified, including obesity and type 2 diabetes. Addressing these factors could help prevent or delay almost half of all dementia cases.

Risk Factors

Ready to talk to your doctor? 

To have a positive and productive conversation with your doctor, it helps to be prepared.

We've put together a list of questions that can help you start the discussion and guide you toward the next steps. 

Recognising the early signs of Alzheimer’s disease 

Symptoms of early Alzheimer’s disease can progress slowly over several years and are often mistaken for normal signs of aging. As a result, some people in the early stages may not realize what's happening and delay seeing a doctor. 

Risk Factors

Recognizing these early signs can make a difference. Here are some of the most common symptoms: 

  1. Forgetting recent conversations or events. 
  2. Misplacing everyday items. 
  3. Forgetting the names of familiar places and objects. 
  4. Trouble finding the right words or following a conversation. 
  5. Asking the same questions repeatedly. 
  6. Showing poor judgment or difficulty making decisions. 
  7. Mood swings, such as increased anxiety or agitation. 

 While we've outlined some key differences below, distinguishing between normal aging and early Alzheimer’s symptoms can be challenging. 

Have you noticed changes?

Behavioural changes often happen so gradually that they're hard to notice at first. It might just be small lapses that are easy to brush aside. But over time, these changes can become more noticeable.

That's why spotting the early signs matters - it gives you the chance to take steps that may help protect your health. 

If you are living with obesity, type 2 diabetes, or other chronic diseases and have noticed even subtle changes in your behaviour, language, or memory, consider talking to your doctor. Opening up about your experiences is an important first step toward understanding what’s happening and finding the right support.
