> BACKGROUND: The apolipoprotein E epsilon 4 (APOE-epsilon
4) allele is a

essential nor
> sufficient for development of the disease. Other factors-genetic
or

form in brains of

that limited

than in
> elderly people without AD because of a difference in
the hosts. We now

with and
> without HSV1 in brain. METHODS: DNA was extracted from
84 samples of brain
> from 46 AD patients (39 temporal lobe, 39 frontal lobe,
three hippocampus)
> and from 75 samples of brain from 44 non-AD elderly people
(33 temporal
> lobe, 36 frontal lobe, six hippocampus). PCR amplification
was used to

FINDINGS: By

frequency was

in brain than in

group, or the

6.3%, respectively).
