Familial & Sporadic Dementia

F amilial Dementia is due to a mutation in specific genes that can be passed from parent to child. Familial Dementia is often called Young Onset Dementia or Early-Onset Dementia, not to be confused with early stages of dementia, because symptoms usually appear earlier in life (before 60-65 years old).

Conversely, Sporadic Dementia has no specific familial or genetic link. Sporadic Dementia is often called Late-Onset Dementia because symptoms appear later in life (after 60-65 years old). The vast majority of neurodegenerative diseases appear after 60-65 years old and have no genetic link, therefore they are called sporadic. For this reason, an emphasis has been put in recent years on establishing risk factors and prevention strategies.
