Insulin resistance (IR) may play a role in most pathogenic processes that promote the development of Late Onset Alzheimer Disease (LOAD). This study was designed to determine the interaction between inhibition of both butyrylcholinesterase (BuChE) and acetylcholinesterase (AChE) with rivastigmine and peripheral insulin resistance (IR) in LOAD.


Seventy-Nine consecutive elderly patients, 31 late onset AD and 48 non-demented patients were evaluated. IR was calculated with HOMA. All of the patients were evaluated through comprehensive geriatric assessments at baseline and in the 6th and 12th months.


End of the study, compared to the baseline values, there was a significant increase in the 6th month in both MMSE and IADL scores (t =2.200, p = 0.036 for MMSE and t =2.724, p= 0.011 for IADL, respectively). Rivastigmine was improved both the scores of MMSE and IADL in elderly patients with LOAD, but there was no significance or correlation between HOMA scores and cognitive status.


In conclusion, inhibition of both BuChE and AChE with rivastigmine was improved the cognition without affecting on the peripheral IR in the elderly patients with LOAD by HOMA. Due to the complexity of disease pathogenesis, it is too early to make general comments, and further longitudinal and long-term studies on this issue are needed.
