Melatonin and Ischemic Stroke: Mechanistic Roles and Action

Abstract EN

Stroke is one of the most devastating neurological disabilities and brain’s vulnerability towards it proves to be fatal and socio-economic loss of millions of people worldwide.

Ischemic stroke remains at the center stage of it, because of its prevalence amongst the several other types attacking the brain.

The various cascades of events that have been associated with stroke involve oxidative stress, excitotoxicity, mitochondrial dysfunction, upregulation of Ca2+ level, and so forth.

Melatonin is a neurohormone secreted by pineal and extra pineal tissues responsible for various physiological processes like sleep and mood behaviour.

Melatonin has been implicated in various neurological diseases because of its antioxidative, antiapoptotic, and anti-inflammatory properties.

We have previously reviewed the neuroprotective effect of melatonin in various models of brain injury like traumatic brain injury and spinal cord injury.

In this review, we have put together the various causes and consequence of stroke and protective role of melatonin in ischemic stroke.
