4 myths and facts about dementia

Dementia is a growing public health concern, affecting millions worldwide. In Canada, Alzheimer’s disease is among the top 10 leading causes of death (2,4,19,20). But what exactly is dementia, and how is it different from normal aging? 

Forgetting events that happened last year, an old coworker’s name, where you put your keys, or occasionally getting lost can be a normal part of aging. In fact, it is fairly common for people over 65 years old to experience some form of memory loss. Unlike dementia, though, age-associated memory impairment is not caused by an underlying medical condition and doesn’t significantly disrupt a person’s day to day life or their ability to complete tasks (1,13,21). 

Dementia is an umbrella term used to describe a set of symptoms caused by the progressive damage and death of brain cells, which gradually affects cognitive functions like memory, thinking, judgment, and communication. Those living with dementia may forget recent events, names of loved ones, repeat themselves, or struggle to perform familiar day to day tasks, such as paying their bills or grocery shopping (1,2,13,21,22). 

Because there is a strong genetic component to dementia, there is no way to fully prevent it. However, you can reduce your risk by staying connected with the people you love, being active, managing stress, eating well, reducing alcohol, not smoking, challenging your brain, practicing good dental and sleep hygiene, taking care of your hearing and vision, and making sure any other health conditions are under control (11,12,14,18).

Early diagnosis and treatment can help manage symptoms and improve quality of life (9). If you or someone you know is experiencing symptoms of dementia, it’s important to seek professional help.
