Hypoxic-ischemic encephalopathy

Horizontal Tabs

Introduction

Hypoxic-ischemic encephalopathy is a form of brain injury caused by oxygen deprivation during the birth process. It can cause sensorimotor and cognitive impairments including physical and intellectual disability. The endocannabinoid system can regulate the underlying processes of Hypoxic-ischemic encephalopathy when its occurring, therefore cannabinoids could help to ameliorate the symptoms related to it.

Prescription Advice

Preclinical evidence suggests CBD to be therapeutic in the treatment of Hypoxic-ischemic encephalopathy.

Given the nature of the disease, sublingual application may be beneficial.

Please follow generic prescription advice.

Please note that, while based on preclinical and/or clinical research, this prescription advice is solely intended as a guideline to help physicians determine the right prescription.

Literature Discussion

The endocannabinoid system plays a role in neonatal Hypoxic-ischemic encephalopathy. Cannabinoid receptors CB1 and CB2 are upregulated and endocannabinoids like AEA, 2-AG, OEA and PEA show increased levels after cerebral ischemia (England et al., 2015; Lara-Celador et al., 2013).

These increased levels of endocannabinoids would reduce apoptotic cell death and reduce brain injury (Lara-Celador et al., 2012).

The endocannabinoid system would be involved in the reduction of glutamate excitotoxicity, neuroinflammation and oxidative stress (Booz, 2011; Capettini et al., 2012; Fernández-López et al., 2013)

Selective activation of CB1 reduces astrocytic reaction, neuronal death and dendritic loss in a stoke model in adult mice (Caltana et al., 2015).

Selective activation of CB2 reduces neuroinflammation, ischemic injury and cognitive deficits in different models of Stroke, probably through modulation of AMPK/CREB signaling (Choi et al., 2013; Ronca et al., 2015; Zarruk et al., 2012).

Selective stimulation of CB2 (SR-144528) significantly decreased thrombin-induced brain edema and reduced the number of Iba-1-positive microglia (Li et al., 2015).

Activation of CB1 and CB2 through synthetic Cannabinoid WIN 55,212-2 in different hypoxia-ischemic newborn animal models showed neuroprotective effects, decreased brain injury and reduced apoptotic cell death by acting on glutamatergic excitotoxicity, TNF-alpha release, and iNOS expression (Alonso-AlcoNADA et al., 2010, 2012, Fernández-López et al., 2006, 2007, 2010; Martínez-Orgado et al., 2003).

Activation of PPAR-γ receptor showed behavioral recovery and microglial supression in a model of Stroke (Yu et al., 2015).

CBD showed neuroprotective effects with functional and behavioral recovery in hypoxia-ischemic animal models (Alvarez et al., 2008; Lafuente et al., 2011).

CBD increased neuronal and astrocyte survival and reduced brain damage and reactive astrogliosis (Hayakawa et al., 2009; Schiavon et al., 2014).

CBD mechanisms would involve the modulation of excitotoxicity, oxidatice stress and inflammation through CB2, 5HT1A, A(2A) and PPAR-γ receptors (Castillo et al., 2010; Hind et al., 2015; Pazos et al., 2012, 2013) .
