Cognitive, affective and behavioural disturbances following vascular thalamic lesions: A review

Multiple thalamo-cortical disconnections in anterior thalamic infarction: Implications for thalamic mechanisms of memory and language

“…The thalamus and language/semantic processing It has been known since the early 20th century that damage to the dominant thalamus occasionally results in aphasia (De Witte et al, 2011). However, information concerning which thalamic nuclei are involved in language processing did not become available because severe and persistent language problems occur only after large thalamic hemorrhages.…”

Bithalamic Dysfunction in Wernicke’s Encephalopathy

“…We speculate that this may have been caused by a transient dysfunction of the bilateral thalami, given the striking signal alteration in this region on MRI. Dysfunction of the right thalamus can cause visuospatial hemineglect on the left side (Bogousslavsky, Regli, & Uske, 1988;De Witte et al, 2011;Watson & Heilman, 1979), and dysfunction of the left thalamus can cause aphasia (Bogousslavsky et al, 1988;De Witte et al, 2011;Kumar, Masih, & Pardo, 1996). For example, in the literature a case has been described where a patient with deep cerebral venous thrombosis with bithalamic infarction presented with a transient left-side visuospatial neglect, aphasia and amnesia (Benabdeljlil et al, 2001), which resembles our case.…”

Free-Drawing from Memory in Constructional Apraxia: A Case Series

“…A bilateral thalamic infarct found in patient (14A) resulted in impairment in the person drawing only, whereas the unilateral lesioned right thalamic lesioned patient (13B) was not found to be impaired in any drawings. A review of 465 participants with vascular thalamic lesions demonstrated that two-thirds of bilateral thalamic participants presented with CA [91]. A recent study found CA in a rare right hander with crossed aphasia.…”
