Stroke is the main cause of vascular cognitive impairment, such as memory impairment.

Stroke blood vessel

The study used the Rey Auditory and Speech Learning Test (RAVLT) to score patients' episodic memory function.

This study uses voxel cerebral blood flow (CBF) and functional covariance network (FCN) methods to explore the neural basis of verbal memory impairment in patients with subcortical stroke.

This study found that in patients with subcortical stroke , the CBF of the affected insular cortex, central cap, IFG , STG and central anterior gyrus decreased.

Stroke patients with ipsilateral insular cortex, the central cover, subcortical stroke patients under the cortex ipsilateral insular cortex, the central cover, IFG IFG , , STG STG front and center back and center-back before the CBF CBF decreases.

Compared with NCs , stroke patients exhibit short-term verbal memory (VSTM) deficits.

Compared with NCs and NCs , stroke patients exhibit short-term verbal memory compared to stroke patients who exhibit short-term verbal memory (VSTM) (VSTM) deficits.

In summary, this study identified multiple changes in the CBF connectivity of the cortex and subcortical areas, which may indicate that the changes caused by subcortical stroke may exist outside the motor system and manifest as the participation of the cognitive function system.

The changes caused by subcortical stroke may exist outside the motor system and manifest as the participation of the cognitive function system.
