In AD, memory loss and cognitive impairment are
accompanied by the degeneration of select neuronal populations
in the hippocampus and cerebral cortex (Morris, 1997).
Although difficult to assess due to the chronic nature of the
disease, apoptotic neurons have been detected in AD brain
and programmed cell death is thought to be one of the factors
contributing to the pathogenesis of AD (Su et al., 1994).
