Treatment with CBD may also decrease the intensity and impact of symptoms commonly associated with PTSD, including chronic anxiety in stressful environments. Exposure to stress can trigger anxiety in PTSD patients and remind them of traumatic experiences. By reducing induced anxiety,CBD may help to regulate the negative effects associated with PTSD.
Antidepressant and neuroprotective properties:
Antidepressants, used for the treatment of depression and some anxiety disorders, also possess numerous neuroprotective properties. Similarly,CBD decreases the production of inflammatory cytokines, the activation of microglial cells, and brain leucocytes. All of which are neuroprotective.
Human imaging studies have demonstrated CBD affects brain areas involved in the neurobiology of psychiatric disorders. A study has showed that a single dose of CBD, administered orally in healthy volunteers, alters the resting activity in limbic and paralimbic brain areas while decreasing subjective anxiety associated with the scanning procedure. In healthy humans,CBD reversed the anxiogenic effects of Δ9-THC and reduced anxiety in a simulated public-speaking task.
