Implicit perceptual-motor skill learning in mild cognitive impairment and Parkinson’s disease.

Abstract: Objective Implicit skill learning is hypothesized to depend on nondeclarative memory that operates independent of the medial temporal lobe (MTL) memory system and instead depends on cortico-striatal circuits between the basal ganglia and cortical areas supporting motor function and planning. Research with the Serial Reaction Time (SRT) task suggests that patients with memory-disorders due to MTL damage exhibit normal implicit sequence learning. However, reports of intact learning rely on observations of no gro… Show more

“…In each of these studies, the authors suggest compensation by the declarative memory system (Beauchamp et al, 2008; Dagher et al, 2001; Moody et al, 2004). Other lines of evidence also suggests that PD patients may depend more on declarative memory, not only for the weather prediction task (Shohamy et al, 2004), but also for sequence learning (Carbon et al, 2010; Gobel et al, 2013) and grammar (Johari et al, In Preparation; Ullman and Estabrooke, 2004). And, analogous to OCD and Tourette syndrome, motor symptom severity in pre-menopausal women with Parkinson's disease has been found to worsen during low estrogen points of the menstrual cycle as compared to high estrogen points (Quinn and Marsden, 1986).…”

“…It is possible that novelty effect merely reflects implicit/procedural learning, which is dissociable from explicit memory (Squire, 1994) and may be relatively preserved in MCI and early Alzheimer's disease (Akdemir, Cangöz, Örsel, & Selekler, 2007;Gobel et al, 2013). Consequently, MCI patients are able to exhibit the rebound in performance that reflects novelty effect.…”
