A new study involving a diverse international sample, including Canada, reveals a decreased risk of mortality for individuals with major neurocognitive disorders like Alzheimer’s. This finding underscores the challenges faced by caregivers and underscores the importance of adjusting available resources to meet the needs of this population.
Published in the esteemed scientific journal Nature, the study examined data from over 1.2 million individuals aged 60 and above who have major neurocognitive disorders. The research indicates a consistent decline in the relative risk of mortality among these individuals in countries including the United Kingdom, Canada (Ontario), South Korea, Taiwan, and Hong Kong. Conversely, Germany and Finland displayed no clear trend, while New Zealand showed an increasing trend.
In Canada, the median survival time for individuals aged 60 to 64 was 4.9 years, with only a gradual decrease in survival with advancing age (2.4 years for individuals aged 85 and older). These findings align with data from the Quebec Ministry of Health, which suggests an average life expectancy of six years following an Alzheimer’s diagnosis, though it can extend up to 20 years.
The study emphasizes the significance of understanding recent survival trends for those diagnosed with neurocognitive disorders to enable policymakers to plan and provide appropriate support and services for the affected population.
Sylvie Grenier, Executive Director of the Quebec Federation of Alzheimer Societies, stresses the need to diversify and adapt services for caregivers to meet the increasing needs resulting from the aging population. Grenier highlights the importance of evolving services and providing respite care throughout the disease’s progression to support caregivers effectively.
Dr. Félix Pageau, a geriatrician, points out that the psychological symptoms of neurocognitive disorders, such as sadness, depression, and behavioral changes, can pose significant challenges for caregivers. While some caregivers find fulfillment in their roles, others may experience exhaustion, emphasizing the need for support and respite services.
The study suggests that early diagnosis and improved disease management may contribute to enhanced survival rates among individuals with neurocognitive disorders. Dr. Pageau emphasizes the importance of early detection and intervention to preserve cognitive abilities and enhance quality of life for patients.
Moreover, advancements in medical technology and lifestyle interventions play a crucial role in delaying disease progression and maintaining cognitive functions. Efforts to enhance support services for caregivers and empower individuals living with the disease to manage their cognitive health are ongoing.
