Abstract:

Transcranial direct current stimulation (tDCS), has shown therapeutic potential for ischemic stroke, but the neural oscillatory mechanisms of its therapeutic effects remain incompletely elucidated. Based on the rat model and clinical stroke patients, this paper combines multiple indicators such as electroencephalography (EEG) relative power (RP), Lempel-Ziv complexity and sample entropy to investigate the mechanism by which tDCS modulates neural oscillations in ischemic stroke. The results indicated that tDCS substantially reduced the RP of the δ frequency band, enhanced the normal oscillation of the α frequency band, and improved the complexity index of the EEG signals. These findings suggest that tDCS could facilitate the recovery following ischemic stroke through the modulation of EEG rhythms.

Ischemic Stroke l: Introduction

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.

Ischemic Stroke ll: Pathophysiology

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

Transient Ischemic Attack l: Introduction

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
