Increased incidence of neurofibrillary tangles (NFT) in non-demented individuals with hypertension.
The incidence rates and numerical densities of argryophilic neurofibrillary tangles (NFT) and senile plaques (SP) were determined in non-demented individuals and subjects with Alzheimer's disease (AD). The non-AD subjects were grouped according to cardiac status; those individuals with critical coronary artery disease (cCAD), those hypertensive individuals without cCAD (HyperT), and those without heart disease (non-HD). The incidence and densities of SP and NFT were significantly greater in AD than any of the non-demented groups. The prevalence of SP was increased in both HyperT and cCAD compared to non-HD controls, while NFT occurrence was accentuated in non-demented HyperT subjects only. The densities of SP and NFT in HyperT were elevated compared to cCAD or both cCAD and non-HD controls; NFT densities were similar in cCAD and non-HD. NFT density increased with increasing age in only the non-HD and cCAD groups, suggesting a possible relationship between disease process and NFT formation in the AD and HyperT populations.
