Abstract

Based on the Squire’s and the Tulving & Schacter’s models about memory system, the neuropsychological evaluation of human memory for clinical purposes usually consists of 7 areas; Orientation, immediate memory, episodic memory, semantic memory, implicit memory, remote memory, and prospective memory. Numerous, seemingly disparate processes such as encoding and acquisition of information, retention and retrieval, rate of decay, and interference effect are assessed in both the verbal and nonverbal modalities for each area. Standardized tests that are normed, reliable, and valid tests as well as a more behavioral or functional measures provided by direct observation, self-reports, or interviews have been used for the evaluation. The majority of patients with memory impairments have other cognitive deficits as well. The poor performance on memory tests may be at least partly attributable to the deficits of other cognitive functions such as attention, information processing, and executive function. Therefore, a comprehensive cognitive assessment is recommended to examine the nature of memory disorders. A complicating factor in the memory assessment of older adults is that appropriate norms for the elderly group may not be available. More age- and cohort-specific norms for the elderly population are needed.
