Background:
Post-stroke hypoesthesia is a common yet often overlooked sequela, involving diminished capacities in touch, temperature, and pain perception. Recent studies suggest that sensory deficits not only hinder functional recovery but also show a high rate of comorbidity with anxiety and depression.
Objective:
This study aims to systematically integrate the neural mechanisms, perceptual processing features, and behavioral consequences of post-stroke hypoesthesia and emotional disorders, to explore their comorbid relationship and propose more targeted rehabilitation strategies based on these mechanisms.
Methods:
This review conducts an interdisciplinary literature search, integrating research from neuroimaging, cognitive neuroscience, and rehabilitation medicine, including 73 relevant studies. The keywords used in the screening are "Hypesthesia," "Impaired Sensation," "Anxiety," and "Depression," covering studies on sensory impairments and mood disorders. By comparing the sensory-emotion interaction mechanisms in stroke and non-stroke populations, a bidirectional model is constructed.
Results:
Findings indicate that post-stroke hypoesthesia results not only from structural damage in regions such as the thalamus, insula, and prefrontal cortex, but also from functional disruptions in perceptual processing. These impairments contribute to a closed-loop mechanism involving neural dysconnectivity and predictive coding dysfunction, which facilitates the emergence of anxiety and depression. In turn, these emotional disorders further suppress sensory recovery, significantly reducing patients' motivation and rehabilitation compliance.
Conclusion:
Post-stroke hypoesthesia should be recognized as a critical etiological and maintaining factor in anxiety and depression. The coexistence of pathological and functional mechanisms underscores the need for rehabilitation strategies that transcend the boundaries of perception, emotion, and cognition. Developing a rehabilitation pathway centered on "sensory-emotional co-regulation" can facilitate early identification, subtype-specific intervention, and comprehensive support for emotional comorbidities following stroke.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

03:12Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
