Dementia has long been a focal point of gerontological healthcare interests. However, recent research and evolving perspectives on dementia have led to a new understanding that it is not merely a disease in and of itself, but rather a symptom that can be caused by various factors. Vascular dementia, traumatic brain injuries, Alzheimer's, and more are different medical conditions that can present with dementia as a prominent symptom. Additionally, lifestyle factors, such as smoking, have been shown to contribute to the onset of dementia.
The COVID-19 pandemic shed light on a significant lifestyle factor that may increase one's risk of dementia. Over two years of social isolation took a substantial toll on individuals globally, and the impact of this isolation on senior citizens, in particular, was notably detrimental. It is crucial to approach the study of dementia, lifestyle factors, and aging from a holistic and intersectional perspective, considering how elements like a lack of digital literacy and changing family structures may have worsened the loneliness experienced by senior citizens.
Efforts have been made in various populations to address the damage caused by isolation and to implement measures aimed at preventing its recurrence post-pandemic. These efforts include programs focused on improving digital literacy among senior citizens and communal initiatives designed to reintegrate older adults into society. However, these efforts are often limited to urban seniors who have access to resources, medical facilities, and familial or communal support. For those senior citizens who lack these advantages, managing dementia can be much more challenging.
