Effectiveness of language training and non-invasive brain stimulation on oral and written naming performance in Primary Progressive Aphasia: A meta-analysis and systematic review

Publication date: Available online 4 December 2019Source: Neuroscience &Biobehavioral ReviewsAuthor(s): Maria Cotelli, Rosa Manenti, Clarissa Ferrari, Elena Gobbi, Ambra Macis, Stefano F. CappaAbstractThe aim of this systematic review and meta-analysis is to examine the efficacy of language training, alone or in combination with non-invasive brain stimulation techniques, designed to improve oral and written naming abilities in Primary Progressive Aphasia (PPA), and to investigate whether gains can be maintained over time and generalize to untrained items. An electronic database search was conducted up to 31st of May 2019. Forty-three articles on language training alone and seven articles on the combined treatment fitted the inclusion criteria for the systematic review. Results indicated that language training, alone or in combination with transcranial direct current stimulation (tDCS), improves oral naming accuracy for trained items in patients with PPA, with a long-term maintenance of the gain over time. Only language training combined with tDCS improves oral naming accuracy for untrained items. Considering written naming abilities, language training combined with tDCS improves performance for both trained and untrained items, immediately after training and at follow-up.

We retrospectively evaluated patients who underwent STA-MCA bypass surgery for acute atherosclerotic occlusion intractable to other treatments. From June 2010 to May 2014, 10 patients underwent STA-MCA bypass surgery for acute atheroscleroti...

AbstractPurpose of the ReviewAlthough visual and somatosensory disturbances are the most common migraine aura (MA) symptoms, patients can also experience other symptoms during their MA. The aim of this review is to provide an overview of studies that report symptoms of dysphasia and other higher cortical dysfunctions (HCDs) during MA, as well as to determine the frequency of HCDs.Recent FindingsFive studies met the inclusion criteria, corresponding to 697 patients overall. The most frequently reported HCDs were those of the language group (range 10 –53%). The occurrence of visual HCDs was noted in 12–40 patient...

Conclusions: We speculated that damages to the basal ganglia disrupted the cortico-subcortical circuits that facilitated the transhemispheric communications of language functions, resulting in decreased interhemispheric FC. Consequently, the intrahemispheric FC increased as a possible compensatory mechanism to restore the language functions. PMID: 31955634 [PubMed - as supplied by publisher]

ConclusionsThis patient demonstrates an unusual presentation of glioblastoma multiforme as thalamic aphasia. It may also point to the potential contribution of the understanding of how thalamic aphasia evolves to characterize the role of the thalamus in language functions.

Publication date: Available online 20 January 2020Source: NeuropsychologiaAuthor(s): Maria Dekhtyar, Swathi Kiran, Teresa GrayAbstractThe bilingual advantage proposes that bilingual individuals have enhanced cognitive control compared to their monolingual counterparts. Bilingualism has also been shown to contribute to cognitive reserve by offsetting the behavioral presentation of brain injury or neural degeneration. However, this effect has not been closely examined in individuals with post-stroke or post-TBI aphasia. Because bilingualism has been suggested as a factor of cognitive reserve, it may provide protective mechan...

ConclusionRegardless of its rarity, it is evident that damage in the left SMA usually results in a clinical syndrome that clearly corresponds to aphasia. Interpreting this as an aphasia can aid in overcoming the limited idea of a “language zone” located in the perisylvian area of the left hemisphere, that was proposed over one century ago.

An elderly woman with h/o stroke and aphasia seemed different to her daughter, and was pointing all over her body as if in pain.They called 911.She had a history of PCI to the circumflex and also of severe mitral regurgitation, status post bioprosthetic valve replacement.  Also a h/o LV aneurysm with thrombus, on anticoagulation, as well as a dual chamber pacemaker. On arrival, the BP was 60/30.Here is the initial ECG:There is atrial pacing and Right Bundle Branch Block (RBBB)There is STE in I and aVL, V5, V6, with reciprocal STD in II, III, aVFThere is appropriately discordant ST depression in V1-V3 (appropriate...
