What is HIE

Hypoxic-ischemic encephalopathy (HIE) is a medical emergency and serious birth complication caused by impaired cerebral blood flow and oxygen delivery to the brain.

The complication may be fatal in newborns and/or cause severe disabilities such as developmental delay, cognitive impairments, or cerebral palsy.1


HIE
Symptoms

Developmental delay, cognitive impairments, or cerebral palsy in newborns caused by impaired cerebral blood flow and oxygen during birth.

Therapeutic
Potential

Preclinical data suggests CBD and cannabinoids receptors may be therapeutic for HIE.

Application
options

Depending on your needs, the optimal type of application may vary. Find more information on our application options.

The connection between Cannabinoids & HIE

Studies find that CBD and THC may have great therapeutic potential and may be used to help treat HIE. CBD and THC are well-known cannabinoids, however, they do not have the same psychoactive effects. THC is psychoactive while CBD does not possess psychoactive effects. According to WHO guidelines, the cannabidiol CBD is generally well tolerated with a good safety profile.

The endocannabinoid system may be involved in controlling the underlying processes of HIE when it is happening. Therefore, cannabinoids may help improve the symptoms associated with it. Preclinical data proposes that the cannabinoid CBD may be a viable therapeutic in the treatment of HIE.2

The literature discussion is an overview of the published results from scientific studies investigating if and how cannabinoids can be beneficial in the treatment of Psoriasis. The overview will be updated regularly to ensure the newest and most accurate information.

Cannabinoid receptors and endocannabinoids may be involved in HIE
The endocannabinoid system is involved in neonatal Hypoxic-ischemic encephalopathy. It was shown that CB1 and CB2 are increased and anandamide, 2AG, OEA, and PEA demonstrate elevated levels after cerebral ischemia.3,4

Astrocytic reaction, neuronal death, and dendritic loss can be reduced through selective activation of CB1 in a stoke model in adult mice. 5

Neuroinflammation, ischemic injury, and cognitive deficits can be reduced through selective activation of CB2 in different models of stroke.6,7,8

In hypoxia-ischemic animal models, CBD has been demonstrated to have neuroprotective properties with functional and behavioral recovery.9,10

Clinical trials are research studies that examine new treatments and evaluate their effects on human health outcomes.

Today, we are not able to provide any clinical trials about cannabinoids and HIE.
