Which is responsible for aphasia by subcortical lesions? Subcortical lesions or the cortical hypoperfusion?
This study showed that aphasia to be more common in cases with cortical hypoperfusion in the dominant hemisphere than in cases without hypoperfusion. Our results provide evidence that direct effect of the lesion in the basal ganglia on the development of aphasia is doubtful.PMID:35984244 | DOI:10.1080/01616412.2022.2112369

Changes in white matter microstructure related to non-linguistic cognitive impairment in post-stroke aphasia.
CONCLUSION: Patients with PSA have non-linguistic cognitive impairment. The integrity of the white matter microstructures can be extensively damaged. Impaired SP and MP in patients with PSA are related to UF damage. PMID: 32697169 [PubMed - as supplied by publisher]

Effects of different frequencies of repetitive transcranial magnetic stimulation in stroke patients with non-fluent aphasia: a randomized, sham-controlled study.
CONCLUSIONS: LF-rTMS and HF-rTMS are both beneficial to the recovery of linguistic function in patients with post-stroke non-fluent aphasia. LF-rTMS produced immediate benefits that persisted long-term, while HF-rTMS only produced long-term benefits. In addition, the benefits produced with LF-rTMS were more marked than those produced by HF-rTMS. PMID: 29589518 [PubMed - as supplied by publisher]

Internal maxillary artery to intracranial artery bypass: a case series of 31 patients with chronic internal carotid/middle cerebral arterial-sclerotic steno-occlusive disease.
CONCLUSIONS: By supplying an adequate flow to a larger flow territory of chronically stenotic/occlusive major cerebral arteries, IMA bypass surgery is efficient for restoring hemodynamics in selected patients and improving their neurological deficits.
