- PurposeTo explore quantitative and qualitative features of anomia in participants with left-hemisphere stroke, Parkinson's disease, or multiple sclerosis.Materials and methodsThis descriptive cross-sectional study compares signs of anomia within and across participants (n = 87), divided into four groups; moderate to severe anomia after stroke (MSAS, n = 19), mild anomia after stroke (MAS, n = 22), PD (n = 19) and MS (n = 27). Aspects analysed include naming accuracy and speed, the nature of incorrect responses, semantic and phonemic verbal fluency, information content in re-telling, and the relationship between test results and self-reports on word-finding difficulties and communicative participation.ResultsAll groups had impaired verbal fluency, prolonged response times and reduced information content in re-telling. The MSAS group had significantly more signs of anomia than the other groups. Results from the other groups overlapped on a MAS-PD-MS continuum. Both semantically and phonologically incorrect responses were common in the stroke groups, while semantically incorrect ones predominated in the PD and MS groups. All four groups reported a similar negative impact on self-perceived communicative participation. Correlations between self-reports and test results were inconsistent.ConclusionsAnomia features have quantitative and qualitative similarities and differences across neurological conditions.

- Background: Multiple sclerosis (MS) commonly includes anomia and other communicative deficits that affect communicative participation and quality of life. Anomia treatment in MS is currently unexplored. Owing to the degenerative nature of MS, compensatory treatment might be preferable to restorative treatment. Semantic feature analysis (SFA) has been reported to have a treatment effect in aphasia and traumatic brain injury, and it can also be used as a compensatory word-finding strategy. SFA might therefore be effective on anomia in MS. Aims: The aim of this study was to evaluate the treatment effects of SFA on mild anomia in MS. Hypotheses were that, if used as a strategy, SFA may improve word-retrieval ability in connected speech, reduce self-perceived word-finding difficulties and increase communicative participation. Methods & Procedures: Two participants (one with relapsing-remitting MS, one with progressive MS) experiencing anomia and reduced communicative participation took part in this early-phase study with a single-case experimental design (SCED). Outcome measures included accuracy and speed in confrontation naming of treated items, correct information units (CIUs) in a re-telling task, self-reported strategy use in everyday communication, self-reported occurrence of anomia and related nuisance, and self-reported communicative participation. Measurements were carried out before treatment, at the beginning of every third treatment session, once directly after treatment, repeatedly during a maintenance phase, and once at a follow-up session ten weeks after treatment. Outcomes & Results: No treatment effects on confrontation-naming ability, re-telling ability or self-reported measures were evident in either participant after treatment with SFA. Effects of repeated measures appeared as reduced response time in confrontation naming. Conclusions: SFA as the sole element of treatment may not be sufficient to obtain treatment effects on mild anomia in MS. Further research is warranted. © 2021 The Author(s).

- Introduction: Anomia affects numerous persons with aphasia. Treatment effects of anomia group therapy have been reported, but the evidence is not comprehensive. This study aimed to explore treatment effects of a naming treatment compared with a non-naming treatment delivered in a group setting. Methods: In a randomized controlled trial, 17 participants with chronic poststroke aphasia underwent group therapy, 2 hours a session, 3 times per week, for a total of 20 hours. The treatment given in the naming group was modified semantic feature analysis (SFA). Treatment content in the non-naming group comprised auditory comprehension, copying text, and reading. The primary outcome measure was accuracy in confrontation naming of participant-selected trained nouns and verbs. Generalization effects were evaluated in single-word naming, connected speech, and everyday communication. Results: Participants in both groups significantly improved their naming of trained items. There were no differences between the groups. The treatment effect did not remain at follow-up 10 weeks after therapy. No other statistically significant changes occurred in either group. Conclusions: Group intervention can improve naming ability in individuals with chronic aphasia. However, similar treatment effects can be achieved using a non-naming treatment as using a naming treatment, such as modified SFA. Further research is warranted to identify the most important elements of anomia group therapy.

- BackgroundVerb Network Strengthening Treatment (VNeST) is a verb-centred aphasia treatment that targets the semantic relationships between a verb (e.g., dig) and related content words (e.g., gardener, hole), aiming to promote word retrieval and sentence production in aphasia. Previous research shows promising results of VNeST in several participants.AimsThis study investigates the effects of VNeST through telerehabilitation on word retrieval and sentence production with treated and semantically related untreated verbs, as well as the possible generalisation to confrontation naming and connected speech. Further, functional communication, communicative participation, health-related quality of life and client satisfaction are explored.Methods and ProceduresA single-case experimental design study with multiple baselines was conducted with two participants with stroke-induced mild-to-moderate Broca's aphasia or moderate-to-severe Wernicke's aphasia who received VNeST through telerehabilitation. Percentage of non-overlapping data, Baseline Corrected Tau and d-index effect size were used to measure improvement in word retrieval and sentence production elicited through video-clip stimuli. The study is registered with ClinicTrials.gov, number NCT05152979.Outcomes and ResultsThe participant with Wernicke's aphasia improved in word retrieval in sentences with trained and untrained verbs and showed some - albeit limited - generalisation to confrontation naming of nouns and verbs. The participant with Broca's aphasia withdrew after half of the planned dosage, as he did not consider VNeST suitable for his needs. He did not improve in word retrieval or sentence production.ConclusionsVNeST shows promise when it comes to improving word retrieval in trained and semantically related untrained stimuli in moderate-to-severe Wernicke's aphasia. This study adds to the existing literature by showing potential improvement in VNeST through telerehabilitation.
