    Abstract:
    Neurofibrillary lesions such as neurofibrillary tangles, neurites and neuropil threads are used as neuropathological markers of Alzheimer's disease (AD). However these lesions are also seen in non-demented elderly cases as well as in several other disorders such as Down's syndrome (DS), dementia pugilistica (DP) and Parkinson's disease. Quantitative studies may therefore help in understanding the pathophysiological role of these lesions. Using a novel image analysis technique we have quantified the extent of neurofibrillary damage in AD, DS and DP. We have found that the extent of neurofibrillary change did not significantly differ between AD and DS, though there were also strong parallels between AD and DP. We conclude that both genetic (as in DS) and environmental (as in DP) risk factors for AD-type pathology provide a similar pattern of neurofibrillary degeneration to that in AD itself suggesting that similar degenerative mechanisms might be triggered in all three conditions.
