چکیده

The cholinergic dysfunction in AD is not necessarily predominant (1,4,5) and responsivity to a cholinesterase inhibitor is not diagnostic for Alzheimer’s disease. Normal young people have improved on psychometric measures in memory and attention after physostigmine challenge (3). Additionally, postmortem neurochemical measures of cholinergic function in AD patients do not correlate with ante mortem measures of cognitive dysfunction as measured with CDR (2) suggesting that patients who have responded to cholinesterase inhibitors in clinical trials (with mild to moderate AD) may have a limited cholinergic deficit. The argument of using acetylcholinesterase inhibitors as a diagnostic challenge in AD is tautological. AD patients may respond to cholinesterase inbibitors and there is a cholinergic deficit in AD. However, a response to cholinesterase inbibitors does not reliably diagnose AD.

Current and future treatments of memory complaints and Alzheimer’s disease

Tacrine was synthesized by Adrian Albert as part of the Australian World War II effort to find an intravenous antiseptic [2]. Use of tacrine to treat AD was unanticipated by the scientific community and there was considerable controversy [3–5]. Yet 7 years later, in 1993,...

Protection against ischemic injury in primary cultured astrocytes of mouse cerebral cortex by bis(7)-tacrine, a novel anti-Alzheimer's agent

The effects of bis(7)-tacrine, a novel acetylcholinesterase inhibitor, on ischemia-induced cell death and apoptosis were investigated in primary cerebral cortical astrocytes of mice. Following a 6 h in vitro ischemic incubation of the cultures, a marked decrease in the percentage of viable cells was observed by lactate dehydrogenase (LDH) release assay. Furthermore, using bisbenzimide staining,...
