[Diaschisis phenomenon in different neurological diseases]

Area of Science:

• Neuroscience
• Neurology

Context:

• The concept of diaschisis, first described in 1914, refers to the reversible depression of brain functions in areas connected to a lesion.
• There has been a significant increase in research on diaschisis over the last two decades, correlating with advancements in functional neuroimaging.

Purpose:

• To describe the phenomenon of diaschisis.
• To outline the different types of diaschisis.
• To discuss the methods for investigating diaschisis and its clinical implications.

Summary:

• Diaschisis is a concept explaining temporary functional impairments in brain regions anatomically or functionally linked to an initial site of damage.
• The phenomenon is characterized by reversible functional depression, distinct from direct tissue destruction.
• This article reviews the historical context, classification, investigative approaches, and clinical significance of diaschisis.

Impact:

• Enhanced understanding of brain connectivity and functional recovery after injury.
• Improved diagnostic capabilities through advanced neuroimaging techniques.
• Potential for novel therapeutic strategies targeting diaschisis to improve patient outcomes.
