Moreover, Prnp −/− mice show synaptic dysfunctions such as altered circadian rhythms and sleep [18], impaired hippocampal dependent spatial learning [19] and age-dependent impairment of memory consolidation [20].
Their symptoms ranged from impairment of memory to schizophrenic and depressive reactions.
Experimental evidence tentatively suggests that electroshock administered to only one side of the head produces therapeutic results equal to those of the standard procedure but with significantly reduced impairment of memory.
Impairment of memory is a characteristic early sign of senility, as well as of hardening of the brain arteries (cerebral arteriosclerosis) at any age, with exaggerated forgetfulness for recent events and progressive failure in memory for experiences that preceded the disorder.
The presence of a secondary task resulted in a global impairment of memory function.
Such findings suggest that the ketamine-induced impairment of memory consolidation may occur through GABAb receptors of the CA1 neurons.
In Experiment 2, pretreatment of an intermediate dose of verapamil also enhanced corticosterone-induced impairment of memory retrieval.
Existing research shows that physiological stress affects working memory and long-term memory performance by the impairment of memory retrieval (e.g., Cornelisse et al. 2011; Smeets 2011).
Relative suppression of IL-6 production was associated with impairment of memory retrieval of emotional (r = 0.48; p = 0.039), but not neutral words (r = − 0.17; p = 0.48).
In that regard, existing research shows that stress affects performance by the impairment of memory retrieval and by cognitive interference (cf. Eysenck et al. 2007; Vogel and Schwabe 2016).
Existing research shows that stress affects performance by the impairment of memory retrieval and by cognitive interference and task-irrelevant thoughts (e.g., Cornelisse et al. 2011; Eysenck et al. 2007; Vogel and Schwabe 2016).
