The brain donation occurs as soon as possible after death. This is done with the utmost care and respect by highly trained staff who perform the brain removals. The limited autopsies are usually carried out at the nearest participating hospital that has appropriate mortuary facilities. After the procedure, the tissue is transported back to the Sydney Brain Bank where it is processed and held.
Brain tissue arrives at the Sydney Brain Bank and is processed and stored in different ways as a means of offering the greatest options for researchers who may want to utilise the tissues for their experiments. This may include freezing some of the tissue so that it can be used for DNA extraction and/or biochemical studies. This is done in the shortest time period possible to ensure viability of most neurochemicals, proteins and RNAs. For participants with a strong family history of disease, the DNA may be screened for genes in which rare mutations have already been associated with neurodegeneration. The remaining tissue is fixed in formalin to preserve it for histological examination.
All brains undergo thorough microscopic examination to characterise each case according to the latest published diagnostic criteria (see list below). This information is communicated to the donors’ recruiting brain donor program. All tissue samples are de-identified to ensure anonymity of the donor.
