There is a recent, thorough, illustrated review of
staining methods for dementia pathology by David Munoz:
Munoz DG. Stains for the differential diagnosis
of degenerative dementias.
Biotech Histochem 1999;74(6):311-20.
If your lab doesn't take this journal (Gasp! And it
costs so little) you can read the Abstract of the
paper by way of PubMed:
The author is a neuropathologist with a keen
interest in techniques and is very active in research
on neurodegenerative diseases, including dementias.
Munoz argues convincingly that a silver method
originally devised by Ferenc Gallyas shows more
plaques and tangles than other techniques (including
immunostaining). His review includes detailed
instructions for the Gallyas variant used in his
own laboratory. He also points out that immuno- and
other staining methods have their places, especially
for detecting lesions of other kinds, which may change
a diagnosis from Alzheimer's to something else even
though plaques and tangles are present.
