Takeaway
In Alzheimer’s disease (AD) patients, the Apolipoprotein E (APOE) ε4 allele was associated both directly and indirectly with transactive response DNA-binding protein 43 (TDP-43) aggregation and hippocampal sclerosis.
Why this matters
The APOE ε4 allele and TDP-43 are associated with cognitive decline in AD however their association with each other is unknown.
