Abstract Background The majority of studies investigating the neural mechanisms underlying treatment in people with aphasia have examined task‐based brain activity. However, use resting‐state fMRI may provide another method examining responsible for treatment‐induced recovery, and allows investigation into connectivity within complex functional networks Methods Eight underwent 12 sessions that aimed to improve object naming. Half employed a phonologically‐based task, half semantic‐based...
Therapy for naming impairments post-stroke typically involves semantic and/or phonologically-based tasks. However, the relationship between individuals' locus of breakdown in word retrieval and their response to a particular treatment approach remains unclear, direct comparisons treatments with different targets (semantics, phonology) yet similar formats are lacking. This study examined eight people aphasia who each received 12 sessions; half sessions involved semantically-based task,...
AbstractBackground: Intensive comprehensive aphasia programs (ICAPs) are gaining popularity in the international rehabilitation community. ICAPs comprise at least three hours of treatment per day over two weeks, have definable start and end dates for one cohort use a variety formats including individual treatment, group therapy, education technology to improve language communication. While intensive approaches demonstrated equivocal results on impairment-based measures, positive changes...
Difficulties with memory and communication are prominent distressing features of dementia which impact on the person contribute to caregiver stress burden. There is a need provide caregivers strategies support maximize abilities in people dementia. In this project, team clinicians, researchers educators neuropsychology, psychogeriatrics, nursing speech pathology translated research-based knowledge from these fields into program practical for everyday use by family professional...
Previous attempts to investigate the effects of semantic tasks on picture naming in both healthy controls and people with aphasia have typically been confounded by inclusion phonological word form target item. As a result, it is difficult isolate any facilitatory semantically-focused task either lexical-semantic or processing. This functional magnetic resonance imaging (fMRI) study examined neurological mechanisms underlying short-term (within minutes) long-term days) facilitation from that...
ABSTRACT Background: People with dementia have a range of needs that are met by informal caregivers. A DVD-based training program was developed using research-based strategies for memory and communication in dementia. The effectiveness the on caregiver experience well-being person evaluated. Methods: pre-test/post-test controlled trial undertaken caregiver–care-recipient dyads living community. Measures carers’ knowledge strategies, burden, positive perceptions caregiving, problem behaviors...
Background.Dementia, a rapidly growing cognitive disorder, has profound impact on the lives of individuals and their caregivers across globe.Digital life storybooks have emerged as promising nonpharmacological intervention to improve wellbeing people living with dementia (PLWD).Objectives.This study aims investigate feasibility developing applying digital storybook for PLWD using telehealth, while evaluating its communication skills, quality (QoL) satisfaction levels. Material methods.A...
Background. The majority of studies investigating the neural mechanisms underlying treatment-induced recovery in aphasia have focused on cortical regions associated with language processing. However, integrity white matter connecting these may also be crucial to understanding treatment mechanisms. Objective. This study investigated arcuate fasciculus (AF) and uncinate (UF) before after for anomia people aphasia. Method. Eight received 12 sessions improve naming; alternating between...
Research suggests that listening to white noise may improve some aspects of cognitive performance in individuals with lower attention. This study investigated the impact on new word learning healthy young adults, and whether this effect was mediated by executive attention skills. Eighty participants completed a single training session learn names twenty novel objects. The comprised 5 phases, each followed recall test. A final recognition test also administered. Half listened during half...
To investigate the effects of dopamine on dynamics semantic activation, 39 healthy volunteers were randomly assigned to ingest either a placebo (n = 24) or levodopa 16) capsule. Participants then performed lexical decision task that implemented masked priming paradigm. Direct and indirect was measured across stimulus onset asynchronies (SOAs) 250, 500 1200 ms. The results revealed significant direct for group at SOAs 250 ms ms, but no SOA. In contrast, showed SOA, while evident These suggest...
Objective: This is a preliminary investigation into the effectiveness of semantic feature training for treatment anomia in Alzheimer disease (AD). Background: Anomia common clinical characteristic AD. It widely held that AD caused by combination cognitive deficits and progressive loss information. Therapy aims to help participants relearn or retain features should, therefore, treat Methods: Two men with one man nonfluent aphasia received 10 sessions focused on relearning names 20 animals...
Dementia is a common neurodegenerative condition involving the deterioration of cognitive and communication skills. Pausing in speech people with dementia dysfluency that may be used to signal conversational trouble social interaction. This study aimed examine speech-pausing profile within picture description samples from healthy controls (HCs) DementiaBank database using Calpy computational processing toolkit. Sixty English-speaking participants between ages 53 88 years (M
Disturbed comprehension of complex noncanonical sentences in Parkinson's disease (PD) has been linked to dopamine depletion and delayed lexical retrieval. The aim the present study was replicate findings activation PD patients with sentence processing difficulties, investigate influence on these changes access. In first experiment, 20 (tested whilst 'on' dopaminergic medication) 23 controls participated a list priming experiment. this paradigm, stimuli are presented as continuous...
Prior semantic processing can enhance subsequent picture naming performance, yet the neurocognitive mechanisms underlying this effect and its longevity are unknown. This functional magnetic resonance imaging study examined whether different neurological underlie short-term (within minutes) long-term days) facilitation effects from a task in healthy older adults. Both short- facilitated items were named significantly faster than unfacilitated items, with items. Region of interest results...
Research has suggested that semantic processing deficits in Parkinson's disease (PD) are related to striatal dopamine deficiency. As an investigation of the influence on activation PD, 7 participants with PD performed a lexical-decision task when and off levodopa medication. Seven healthy controls matched terms sex, age, education also participated study. By use multipriming paradigm, whereby 2 prime words were presented prior target word, priming effects measured across stimulus onset...
