There is abundant evidence that memory impairment in dementia in patients with Alzheimer’s disease (AD) is related to explicit, conscious forms of memory, whereas implicit, unconscious forms of memory function remain relatively intact or are less severely affected. Only a few studies have been performed on spatial memory function in AD, showing that AD patients’ explicit spatial memory is impaired, possibly related to hippocampal dysfunction. However, studies on implicit spatial memory in AD…

Implicit memory performance was intact in patients with MCI and ATD; however, implicit memory performance of the patient groups differed according to the level of processing manipulation, which should be used for clinical diagnosis in ATD.

Preserved Implicit Memory in Dementia: A Potential Model for Care
- PsychologyAmerican journal of Alzheimer's disease and other dementias

A new approach to dementia care is described, the PIM model, which translates evidence from implicit memory research into a practice model of dementia care that predicts that function can be sustained longer for persons with AD through interventions and environments that activate an individual's PIM.

Data suggest that extensive involvement of the hippocampal-amygdala complex plays a major role in explicit memory loss, and damage to associative cortical areas likely is involved in repetition priming deficits.

The results clearly show age-related decline in explicit spatial memory, while implicit spatial memory was unaffected, and it was found that the effects of errorful learning were related to explicit memory function, and not implicit processing, corroborating and extending recent findings.

The findings suggest that poor performance on the RLT in AD patients is characteristic of poor spatial orientation or spatial reasoning, and episodes of TD inAD patients may occur secondary to poor spatial Orientation.
