What Causes Dementia? Unraveling the Complex Web of Risk Factors
Published: Jun 04, 2024
Dementia isn't caused by just one thing. Let's dive into the multiple risk factors that contribute to its development.

Understanding Genetic Influences
Genetic factors significantly contribute to dementia risk, with Alzheimer's disease being a primary example. Having a parent with dementia doubles the risk, especially if diagnosed early. Mutations in specific genes are linked to early-onset Alzheimer's, while late-onset involves more complex genetic interactions.
Impact of Cardiovascular Health
Cardiovascular health plays a vital role in dementia risk. Conditions like diabetes and hypertension, especially when present in midlife, increase the chance of cognitive decline. Managing these conditions early can help mitigate the risk of developing dementia later in life.
Trauma and Brain Health
Head injuries, even mild ones, can increase dementia risk. Traumatic brain injuries are linked to a higher incidence of Alzheimer's and other dementias. Protecting the head and reducing injury risk is essential for long-term brain health.
Frequently Asked Questions
Genes can double the risk, especially with early-onset cases.
Yes, poor cardiovascular health increases the risk.
Yes, even mild trauma can increase dementia risk.
