What is the typical life expectancy for people with logopenic progressive aphasia?

Little is known regarding the overall life expectancy of individuals with logopenic progressive aphasia. This dementia is associated with Alzheimer’s disease in the majority of cases.[1] Life expectancy for people with Alzheimer’s disease has been estimated to be between 3 to 10 years.[2] However, due to the many variables that influence life expectancy, making individualized life-expectancy predictions can be very difficult.

What is the prognosis for people with logopenic progressive aphasia?

Typically during the first few years following disease onset, signs and symptoms primarily involve speech and language problems. Pronounced behavioral problems are not as common in logopenic progressive aphasia, as in other forms of primary progressive aphasia.[3] Caregiver experience of changes in behavioral symptoms and everyday skills has been demonstrated to be similar to that of Alzheimer’s disease.[1]
