Cannabinoid affect on depression

Takeaway While many people use cannabidiol to relieve pain, more scientific research is needed to be sure it is safe. Understanding cannabidiol can help overcome the stigma associated with it. Some people experience side effects when taking cannabidiol CBD and there are other factors to consider before using CBD oil for pain.

Cannabinoid affect on depression

This article has been cited by other articles in PMC. The objective of this study was to evaluate the effect of cannabinoid on cortical spreading depression CSD in rat brain. Cannabis has been used for centuries for both symptomatic and prophylactic treatment of different types of headaches including migraine.

CSD is believed to be a putative neuronal mechanism underlying migraine aura and subsequent pain.

CBD oil for pain management: Effects, benefits, and uses

Suppression of CSD by activation of CB1 receptors points to the potential therapeutic effects of cannabinoids in migraine with aura. More research is Cannabinoid affect on depression before we know whether cannabinoids may be helpful in treating migraine pain. Endocannabinoid, Headache, Marijuana, Migraine, Pharmacotherapy, Synaptic transmission Introduction Cannabis has been traditionally used as a therapeutic agent in central nervous system disorders such as epilepsy and migraine headache for several centuries 12.

A large number of studies using Delta9-tetrahydrocannabinol THCthe main pharmacologically active constituent of cannabis, or cannabinoid synthetic derivatives have substantially contributed to advance the understanding of the neurobiological mechanisms produced by cannabinoid receptor activation 1.

Cannabinoids evoke various central effects, such as sedation and analgesia via an activation of the CB1 34. It has been suggested that cannabinoid receptors may play a significant role in modulation of nociception as well as in psychomotor control, memory function, neuroendocrine regulation, control of movement, appetite regulation, emesis, and many other brain functions 5.

Migraine has numerous relationships to endocannabinoid functions. Endocannabinoid deficiency has been suggested to underlie the pathophysiology of migraine 1.

The attributes of cannabis to affect serotonergic, dopaminergic, anti-inflammatory and glutamate mechanisms of migraine have rendered it a proposed drug for headache treatment, although clinical studies providing a scientific basis for the potential efficacy of cannabinoids in migraine are limited.

Several studies revealed a potent cannabinoid agonistic activity at 5-HT1A receptors and an antagonistic property at 5-HT2A receptors, which suggest the putative efficacy of therapeutic cannabinoids in acute migraine and in its prophylactic treatment, respectively 136.

The midbrain periaqueductal grey matter, a putative migraine generator area, was shown to be modulated by endocannabinoids 7. Therapeutic potentials of cannabinoid receptors in migraine was suggested by the observations that cannabinoids inhibited neuronal firing in the trigeminocervical complex, neurogenic dural vasodilatation, and calcitonin gene-relatad peptide CGRP - capsaicin- and nitric oxide NO -induced dural vessel dilation induced by trigeminovascular stimulation 89.

The preclinical data supporting the antinociceptive role of cannabinoids, and some clinical data noting their benefit in pain, indicate that further research is needed before cannabinoids are recommended clinically for pain or headache Cortical spreading depression CSD refers to a phenomenon that manifests as a self-propagating wave of neuronal hyperexcitability followed by a transient depression 11 CSD is accompanied by characteristic ionic, metabolic, and hemodynamic changes and may play an essential role in some neurological disorders including migraine with aura 13 The hypothesis that the aura is the human equivalent of CSD has been well established Propagation of a CSD-like wave in human neocortical tissues generates aura symptoms in migrainous patients Furthermore, it was proposed that CSD might also trigger the rest of the migraine attacks including pain 17 - Materials and Methods The experiments were performed on adult rat g somatosensory neocortical slices.

After 30 min of incubation, CaCl2 was elevated to 2. A glass electrode filled with 2 M KCl was fixed in a special holder connected with plastic tube to a pressure injector and the tip inserted into the layer I-II of the neocortical slices. CSD-like events were evaluated with respect to their amplitude, duration and velocity rates.

CSD duration was defined as the interval between the time of half-maximal voltage shift during onset and recovery of the negative DC potential deflection 21 Long-term potentiation Single pulses of electrical stimulation were applied through a bipolar platinum electrode attached to the white matter perpendicular to the recording electrodes.

Evoked field excitatory postsynaptic potentials fEPSP were recorded in the third layer of neocortical slices. The amplitude of fEPSP 1 ms after the onset was measured for data analysis.

In long-term potentiation LTP experiments, the cortex was sequentially stimulated once every minute. LTP was operationally defined as the mean change in fEPSP amplitude in response to five stimuli given 30 min after tetanic stimulation compared with the mean response to five test pulses applied immediately before the stimulation.

Tetanic stimulation was applied 60 min after application of drug 21 Experimental protocols Two different experimental protocols were used, each of which consisted of several periods.8 Major Cannabinoid Acids Produced by Cannabis.

Cannabis doesn’t directly make the most famous cannabinoids associated with the plant, THC and leslutinsduphoenix.comd, it synthesizes several cannabinoid.

Mar 16,  · Cannabis, itself, does not seem to contribute to chronic depression. One study surveyed over 4, people, asking them about their marijuana use and depressive symptoms using The Center for Epidemiologic Studies Depression scale and found that marijuana use (whether frequent or not) did not contribute to an increased rate of leslutinsduphoenix.com: Abby Hutmacher.

While the Food and Drug Administration (FDA) hasn't recognized or approved the use of the marijuana plant as medicine, many states have legalized marijuana for medical use. Long-term depression (LTD), in neurophysiology, is an activity-dependent reduction in the efficacy of neuronal synapses lasting hours or longer following a long patterned stimulus.

LTD occurs in many areas of the CNS with varying mechanisms depending upon brain region and developmental progress.
