Major Risk Factors For Dementia

Genetic Predispositions

Individuals are more likely to develop dementia if a close relative such as a parent or sibling has the condition. This risk goes up if they have more than one close family member with dementia. It should be noted that having family members with dementia does not guarantee someone will also develop the condition. It just means they are more at risk of developing it than someone who does not have the family history. To be sure, individuals can get genetically tested to find out what their likelihood of being diagnosed with dementia is. A gene called ApoE4 is strongly associated with dementia. Individuals who carry this gene are two to four times more likely to develop the condition than those who do not carry the gene. Those who carry two copies of this gene are ten times more likely to see dementia in their lifetime.
