The impact on life expectancy depends on the individual condition, [9] but is usually severe without treatment. [1] [3] It's estimated only 25–29% of people affected survive to adulthood, and only 10% to the age of 50. [1] The median life expectancy is around 9 years, and the average life expectancy is 16.3 years. [1]
The hallmark symptom of LATE is a progressive memory loss that predominantly affects short-term and episodic memory. [1] This impairment is often severe enough to interfere with daily functioning and usually remains the chief neurologic deficit, unlike other types of dementia in which non-memory cognitive domains and behavioral changes might be noted earlier or more prominently.

A new study found the biggest risk factors and predictors at 60 for dementia at 80. Neurologists weigh in on the research and share ways to prevent dementia.
Many causes of dementia are neurodegenerative, and protein misfolding is a cardinal feature of these. [60] Other common causes include vascular dementia, dementia with Lewy bodies, frontotemporal dementia, and mixed dementia (commonly Alzheimer's disease and vascular dementia).

The normal life expectancy for 60 to 70 years old is 23 to 15 years; for 90 years old it is 4.5 years. [226] Following AD diagnosis it ranges from 7 to 10 years for those in their 60s and early 70s (a loss of 13 to 8 years), to only about 3 years or less (a loss of 1.5 years) for those in their 90s.
Unfortunately, doctors “don’t really know the cause of this,” he adds. It's possible that sundowning in dementia patients is caused by a combination of hormonal changes, brain deterioration ...
Symptoms of frontotemporal dementia progress at a rapid, steady rate. Patients with the disease can survive for 2–20 years. Eventually patients will need 24-hour care for daily function. [60] Cerebrospinal fluid leaks are a known cause of reversible frontotemporal dementia. [61]
