Abstract
Intracerebral hemorrhage (ICH) is a life-threatening type of stroke that disrupts the normal neurological function of the brain. Clinical studies have reported a non-linear J-shaped association between alcohol consumption levels and the occurrence of cerebral stroke. Specifically, alcohol intoxication increases stroke incidence, while moderate alcohol pre-conditioning decreases stroke frequency and improves outcomes. Although alcohol pre-consumption is likely a crucial player in ICH, the underlying mechanism remains unclear. We performed 1-h alcohol pre-conditioning followed by ICH induction in Sprague-Dawley (SD) rats to investigate the role of alcohol pre-conditioning in ICH. Interestingly, behavioral test analysis found that ethanol intoxication (3 g/kg) aggravated ICH-induced neurological deficits, but moderate ethanol pre-conditioning (0.75 g/kg) ameliorated ICH-induced neurological deficits by reducing the oxidative stress and proinflammatory cytokines release. Moreover, we found that moderate ethanol pretreatment improved the striatal endoplasmic reticulum (ER) homeostasis by increasing the chaperone protein expression and reducing oxidative stress and apoptosis caused by ICH. Our findings show that the mechanism regulated by moderate ethanol pre-conditioning might be beneficial for ICH, indicating the importance of ER homeostasis, oxidative stress, and differential cytokines release in ICH.

Abstract
Abstract
Aims
To investigate the dose–response relationships between alcohol and intracerebral hemorrhage (ICH), the impact of alcohol on the outcome of ICH and possible mechanisms underlying hypertensive ICH (HICH) caused by heavy drinking.
Methods
Literature search from 1985 to August 2019 in the PubMed database.
Results
The relationship between low-middle alcohol consumption and ICH remains controversial for various reasons, whereas chronic heavy drinking increases the incidence of ICH and exerts worse outcome. More attention is needed to clarify the characteristics of chronic alcohol intake and binge drinking. Chronic alcohol abuse tends to elevates blood pressure, resulting in increased occurrence of HICH and exaggerated HICH-contributed brain injury.
Conclusion
It is important to develop strategies to promote reasonable intake categories, prevent alcoholism and thus reduce the risk of ICH.
