What It’s Like Having a Grandparent with Alzheimer’s

In all the TV shows I watched as a little girl, the kids would often visit their grandparents on the weekends. Whether it was an episode of Caillou or the Berenstain Bears, the children would always have a fun weekend with their grandparents, as they baked cookies together and looked through old photos. But for me, my weekends with my grandparents were nothing like the TV shows. What I didn’t understand at the time was that my grandfather was beginning to develop dementia.

Since his diagnosis of Alzheimer's disease, my grandpa's condition has only worsened. Sometimes, he leaves the house to go for a walk, but then forgets how to get home and cannot remember his own address. Fortunately, his neighbours help him and bring him home safely. After a few incidents of wandering, we knew that it was too dangerous for my grandpa to leave the house alone. So we installed a second lock on his door. Today, he can’t leave the house alone unless my grandmother unlocks the door.

But the hardest part of this journey is seeing my grandfather become frustrated with his failing memory. "I’m useless; I can’t remember anything" are his most common phrases nowadays. It's really heartbreaking to see him so discouraged.

Despite the burden of this illness on both my grandpa and myself, it is more important that I cherish the moments I spend with him, rather than focusing on his suffering. I'm grateful that he still remembers me and I choose to take each day as it comes, because I never know when it will be the last. I'm afraid of the day when he won’t remember me anymore – when I will no longer be his only granddaughter, but a stranger. The day when he loses his battle to dementia will be the most difficult day. So that's why I hold onto our memories, even if I have to explain to him what a selfie is every time. I’m blessed to hold his hand every step of the way, while this illness takes him away from me. Although his condition deteriorates, I love him unconditionally and hold in my heart the one thing that will never change – dementia will never take away my grandfather and our memories shared together. I will always remember them, as long as I can.

My story is only one in 1.1 million Canadians who are affected directly or indirectly by this disease. For those of you who have a loved one with dementia, know that you are not alone. Yes, it will be difficult, but know that the pain and suffering that comes with the illness is accompanied by the compassion and love we have for them.

Ask the Expert: In the future, will dementia start affecting individuals at younger ages?

No! In fact, in the future dementia will hopefully begin even later in life, if we manage to control obesity, diabetes, high blood pressure, and other vascular risk factors. 

Only a small number of cases of dementia begin in the 50s (and some even in the 40s), and many of these are either cases of "Familial Alzheimer's disease" or Frontotemporal dementias which are strongly genetic illnesses. The most common dementia is Alzheimer's disease which typically begins in the 60s, 70s and 80s. While genetic factors do influence the age of onset of this disease, vascular risk factors also play a role. By reducing the rates of smoking, treating high blood pressure, high cholesterol and diabetes, and reducing the rates of obesity, the onset of this illness could be delayed. Results from the famous Framingham Heart Study in the US have already begun to show the incidence of Alzheimer's disease appears to be declining, likely as a results of the benefits of these interventions. Along with exercise, mentally stimulating activities and a Mediterranean diet, it is possible we can even push the onset of the disease much later into life. Finally, if we can find a disease modifying agent that delays the onset of the illness by even 5 years, we will be able to cut the number of patients with dementia in half.

Research Update: The Relationships between Dementia and Nutrition

In 2014, researchers from the Global Observatory for Ageing and Dementia Care at King’s College London investigated the relationship between dementia and nutrition. The report, published by Alzheimer’s Disease International, touched on many links between nutrition and dementia, as summarized below.

First, a connection was found between nutrition, fetal development, and dementia, as the micronutrients and fats accumulated as a fetus can affect the development of the brain and nervous system. In turn, this may affect one’s risk of developing dementia in the future. 

In addition, researchers investigated the relationship between dementia and fats. While fats may be harmful for the brain if consumed in excess at mid-life, they can also act as an energy reserve to combat the neurodegenerative effects of dementia. However, further research is needed to explore the relationship between fats and cognitive function.

The report also explained that a Mediterranean diet may be key to preventing dementia. The Mediterranean diet, which consists of lots of vegetables, olive oil and fish, can reduce the risk of cardiovascular disease. As a result, this may potentially reduce the risk of dementia. There are many studies reporting a positive correlation between a Mediterranean diet and a lower risk of dementia; however, some studies have found no correlation at all.

Aside from nutrition and dementia prevention, there is also a link between malnutrition and patients with dementia. Weight loss is very commonly observed in dementia patients due to lower nutritional intake. It was found that dementia-related neurodegeneration may impact brain regions responsible for appetite control, thus contributing to the observed weight loss. The reason why malnutrition is a notable symptom of dementia is because in many cases, it proves to be fatal. This study suggests that eating habits of dementia patients can be improved through: caregiver education about the importance of nutrition, giving patients oral nutritional supplements, using feeding assistance tubes, and more.

Ask the Expert: Are there any blood tests to screen for dementia?

Unfortunately, there are no blood tests to screen for dementia. In fact, there are no tests of any kind that can make the diagnosis of dementia, while a person is alive. The diagnosis is made by a medical doctor (MD) who takes a history, performs a physical exam, and does some cognitive testing, which includes things like assessing memory, concentration and language skills. Frequently, the physician will also order some routine blood tests to ensure there are no other medical conditions that could interfere with memory - like diabetes, thyroid problems or infections. The MD might also order a CT scan or MRI of the brain to look for evidence of strokes, or patterns of brain shrinkage that could help identify if a specific type of dementia is more likely than another. 


The search for a blood test which accurately identifies Alzheimer’s disease or other types of dementia is an active area of research, though no tests developed so far are sufficiently accurate.
