Cognitive Mechanisms of Memory Impairment Following Traumatic Brain Injury
Memory impairment is common following traumatic brain injury (TBI). In recent years, researchers have demonstrated that the processes underlying memory formation (working memory, encoding, consolidation, and retrieval) are interrelated but dissociable events.The following study was designed to …

EEG Features of Working Memory Impairment in Alzheimer’s Dementia and Mild Cognitive Impairment
The presence of working memory impairments in individuals with Alzheimer’s Dementia (AD) or Mild Cognitive Impairment (MCI) is well-accepted; however, the neurophysiological mechanisms contributing to these impairments have not been fully elucidated. Research has reliably shown that oscillatory …

Factors affecting responsiveness to teaching strategies in the rehabilitation of acquired memory impairment
… examines the extent to which specific cognitive impairments should be taken into account when planning memory rehabilitation interventions based on teaching strategies such as cueing and errorless learning. The second paper is an empirical study which compares the effectiveness of implicit and …

The Relationship Between Neuropsychological Functioning, Biomarker AV-1451, and Subjective Memory Impairment in a Cognitively Normal Sample
<p>Mild cognitive impairment (MCI) is often a prodromal stage for Alzheimer’s disease (AD) development, with those diagnosed with MCI at increased risk for developing AD. The present study aimed to provide data to support a prodromal stage of MCI via analysis utilizing the neuropsychological domain …

The relationship between neurocognitive disorders, prospective memory impairment and white matter damage in clade C HIV-positive subjects
… To examine the relationship between prospective memory, cognitive function and Diffusion tensor imaging (DTI)/ White matter integrity of human immunodeficiency virus (HIV) positive individuals in the Western Cape. We hypothesize that: 1. Individuals infected with HIV will exhibit significantly …

THE INFLUENCE OF MISLEADING POSTEVENT INFORMATION ON ITEM RECOGNITION
… information: (1) whether misinformation leads to memory impairment, and (2) whether experimental findings are generalizable to real world eyewitnesses.</p><p>Subjects were shown four critical event items in a series of slides. Afterward, all subjects were misinformed (misled condition) that for …

The everyday functioning of individuals with cognitive difficulties and their families : going beyond neuropsychological assessment
… family members in interventions for adults with memory impairment is reviewed.Part Two is an empirical paper, which explores how objective cognitive performance translates into self-reported cognitive skills and diabetes self-management in individual with Type 1 Diabetes.Part Three comprises the …

Exploring the Impact of Virtual Reality and Avatars on Social Engagement in Older Adults at a Day Service Program
… older adults (aged 87–93) showing symptoms of memory impairment at a nursing home day service program participated. Using a single-case alternating-treatments design, three conditions were compared: VR, VR with an avatar, and Pictures. Dependent variables were verbal initiations, word count, …

The nature of semantic memory deficits in Alzheimer's disease : evidence from event-related brain potentials and reaction time measures
The nature of semantic memory deficits in Alzheimer's disease: Evidence from event-related brain potentials and reaction time measures Semantic memory impairment is commonly observed in patients with dementia of the Alzheimer type (DAT); however the nature of the impairment is unclear. Some …

Depression status predicts false memory on recognition tasks
It has long been assumed that depression leads to memory impairment. However, previous research findings have been plagued with inconsistencies in methodology and overall findings. Specifically, there has been some debate over whether or not depressed people are capable of spontaneous strategy use, …

The Effect of Caffeine and Choline on Short-term Memory
… combined with choline could improve short-term memory in healthy adults. The study tested the effect of choline (2 gm) alone and in combination with several concentrations of caffeine (25 mg, 50mg and 100mg) on short-term verbal and visual memory and attention. The Wide Range Assessment of …

Errorless Learning of Prospective Memory Tasks: An Experimental Investigation in People with Memory Disorders.
Prospective Memory (PM), or the ability to act upon delayed intentions, is cognitively complex as it requires a combination of mnemonic, attentional and executive abilities. PM tasks can be particularly challenging for people with cognitive impairment, and it is important to identify effective …

The investigation of the neuronal and synaptic defects in early stage of amyloid-beta pathology
… and synchronicity. These changes correlate with memory impairment rather than seizure severity, highlighting ATF4 as a necessary component in learning and memory performance. This suggests the potential role of ATF4 in learning and memory impairment in AD, warranting further research. Taken …

Measuring Memory in an Alzheimer's Treatment Trial Using a Visual Search Task
… Disease (AD) is characterized by episodic memory deficits attributed to damage to the hippocampal formation. AD therapies specifically targeting hippocampal function may be best evaluated through the use of selective hippocampal tasks. I used a nonverbal hippocampal-dependent …

The Impact of Methylenetetrahydrofolate Reductase (MTHFR) Deficiency in a Paraquat Mouse Model of Parkinson’s Disease
… Mthfr+/- mice demonstrated motor and a trend for memory impairment compared to Mthfr+/+ mice. No differences in SN DA neuron numbers or antioxidant activity were seen, however, increased oxidative stress and antioxidant activity were observed within the dorsal striatum of Mthfr+/- mice. These …

The Negative Impact of Posttraumatic Stress Disorder on Working Memory of Icelandic University Students
Working memory is a complex cognitive system essential for everyday living. It is important for all kinds of cognitively demanding activities such as reading, writing and carrying out conversations. Working memory capacity has been compared to a resource that ,,feeds'' working memory. Is the …
