CBD Oil: A Cure for Depression?
What is Depression?
Depression is a mental health disorder associated with significant morbidity and mortality, being a major risk factor for suicide, substance abuse, poor outcomes of medical conditions, and impaired functionality. It is characterized by flattening of mood, loss of emotional expression, and retardation of thought and movements. Individuals who have depression usually have a depressed mood, loss of interest in activities they were usually interested in, sleep disturbance, loss of energy, and reduced ability to thick or focus.
The American Psychiatric Association’s Diagnostic Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) categorizes depressive disorders into major depressive disorder, persistent depressive disorder, premenstrual dysphoric disorder, disruptive mood dysregulation disorder, and depressive disorder due to a medical condition. However, all these classes of depression are characterized by the presence of a sad or irritable mood with associated difficulty in thinking, concentrating, and carrying out normal physical tasks, impairing the individual’s daily functioning.
Stats about Depression
Between 2009 and 2012, approximately 7.6% of Americans aged 12 and above were diagnosed with depression and it was more common among females and persons aged 40 and 59. In 2015, about 16.1 million adults aged 18 and over had a minimum of one depressive episode in the previous year.
Depression has been found to occur in children at an incidence rate of 0.9% in preschool-aged children, 1.9% in school-aged children, and approximately 4.7% in adolescents. In prepubertal children, depression occurs in boys and girls at an equal rate. Generally, depression in men and women has the highest rates in those aged between 25 to 44 years and the incidence of severe depression increases with age.
What are the Traditional Treatments for Depression?
There is a wide range of treatments for depression which have proven effective in improving symptoms. A combination of medications and psychotherapy is effective in reducing the symptoms of depression, and therapy with either form alone is often ineffective. Combination therapy has been found to increase quality of life and improve treatment compliance in patients with depression.
Advanced treatment techniques used for the treatment of depression include electroconvulsive therapy which uses high-energy electric stimulation, and bright-light therapy involving exposure of an individual with depression to bright light at an intensity of 10,000 lux for a period of one hour in the morning.
Therapy for Depression
Psychotherapy is often combined with medications in the treatment of depression. There are different types of therapy for depression and these can be grouped based on their efficacies. A therapy is considered “efficacious and specific” if studies in at least two settings (hospital, home therapy, rehab center etc.) have proven it more effective than medications. A therapy is considered “efficacious” if it has been proven from at least two settings that it is superior to no treatment at all, and it is “possibly efficacious” if it has been proven effective in at least one study in a single setting.
Examples of efficacious and specific therapies include cognitive behavioral therapy, problem-solving therapy, and interpersonal therapy which help the individual modify their behaviors and interpersonal relationships. An example of an efficacious therapy includes mindfulness-based cognitive therapy to prevent a recurrence or relapse, and an example of possibly efficacious therapy is continuation cognitive therapy to prevent recurrence by helping the individual develop positive thinking and behavioral patterns.
Medications for Depression
Medications used for treating depression are of different classes, each with a different mechanism of action, characteristics, and side effects. Some of these drugs include Fluoxetine (Prozac), Citalopram, Amitriptyline, Imipramine, and Nortriptyline. These drugs generally increase the concentration of stimulant substances in the brain to improve the depressive symptoms.
Home Remedies for Depression
Patients with depression could benefit from a number of home remedies which could help to improve their symptoms, in addition to antidepressants and therapy:
- St. John’s wort – This plant, although not approved for treatment of depression by the FDA, has been linked with increased amounts of serotonin in the body correlating to improvement of depressive symptoms.
- Omega-3 fatty acids – Omega-3 fatty acids are commonly found in fish such as salmon, sardines, and trout, and this substance has been linked to improvement in depressive symptoms.
- SAM-e – S-adenosylmethionine (SAM-e) is artificially designed to function like chemicals in the brain which elevate mood. It is considered a supplement useful in improving symptoms of depression.
- Folate – Folic acid which is found in a number of foods such as beans, lentils, dark leafy greens, and fortified cereals have been found to improve the effectiveness of medications used in treating the disorder.
What is CBD?
Cannabidiol (CBD) is a naturally occurring chemical compound found in the hemp plant. It is one of the numerous unique compounds called cannabinoids which naturally occur in hemp. Generally, cannabinoids can be produced in the body (these are known as endocannabinoids) or found in the hemp plant as phytocannabinoids. CBD is industrially extracted from the cannabis plant and separated from the other cannabinoids, representing about 40% of cannabis extracts.
CBD is a phytocannabinoid which helps to stimulate the regulation of the central nervous system. CBD, therefore, helps supplement the effects of endocannabinoids in regulating appetite, mood, functions of the immune system, sensation, and keeping our bodies working normally. CBD oil is made from hemp plants and can be purchased legally in the United States. CBD is available in different forms such as tinctures, concentrates, capsules, sprays, tapes, and topicals.
CBD vs. THC
Most times, people interchange CBD for tetrahydrocannabinol (THC), another cannabinoid found in the hemp plant. Both of them represent the commonest compounds found in the plant. However, they have numerous differences.
THC, unlike CBD, is intoxicating causing a high and euphoria. It is responsible for the “high” felt by marijuana users. CBD, on the other hand, is not a psychoactive substance as it does not act via the same biological pathways in the body as THC.
CBD Oil Effects
Although, CBD oil has not been approved by the FDA for the treatment of any condition, there have been several studies demonstrating some of its health benefits:
- CBD has been shown to have anti-oxidant properties which means that it is capable of mopping up toxic substances obtained from food or generated in the body. These substances are often at the center of inflammatory conditions such as myocardial infarction, inflammatory bowel disease, and stroke.
- Oxidative stress caused by the release of these toxic substances causes age-related diseases such as Alzheimer’s disease and Parkinson’s disease and CBD has been found to protect against these degenerative diseases of the brain and reduce their clinical progression in patients suffering from them. CBD may also help in the clinical improvement of some autoimmune disease such as lupus and rheumatoid arthritis.
- Clinical trials have shown that CBD oils are effective in the treatment of epilepsy and other seizure disorders.
- Studies have shown that CBD may have therapeutic benefits for brain disorders such as psychosis, depression, and multiple sclerosis.
- Other benefits of CBD are currently being investigated, including its effects on anxiety and depression, as well as on social anxiety disorder and post-traumatic stress disorder.
Does CBD Get You High?
CBD is a non-psychoactive form of cannabinoid which has been found not to interfere with the cognitive functions of the brain. It does not get you “high,” in contrast to THC, which alters the cognitive functions of the brain.
Is CBD Addictive?
According to a recent report by the World Health Organization (WHO), CBD is not addictive and it has no potential for abuse or dependence. This is mainly because CBD does not contain any addictive substances, in contrast to THC and some cannabinoids which contain such and are, therefore, capable of being addictive.
Is CBD Safe?
There have been extensive reviews on the toxic potentials of CBD and reports have revealed that CBD has a relatively low toxicity. It has been found to be safe with little potential for adverse effects. CBD was found to have no effect on fetal development and other bodily functions. Generally, CBD does not produce the adverse effects seen with THC and other psychoactive cannabinoids. However, reports demonstrate that some reactions may occur as a result of its interactions with other drugs co-administered with it.
How Could CBD Help with Depression?
CBD has been found to be effective in the treatment of depression. While CBD does not cure the condition, it has been linked to improvement of the symptoms.
The cannabinoids produced in our bodies (endocannabinoids) help to regulate several functions of the body such as mood, pain sensation, sleep, and appetite. These substances exert their actions by binding to specific points of brain cells called the receptors through which they potentiate the actions of a substance called serotonin which acts to improve mood and reduce stress levels. Serotonin also acts by binding to its receptors in brain cells. When these chemical substances bind to their respective receptors, they trigger a series of events within each brain cell stimulating processes that improve mood and stress control.
CBD has been found to help improve depressive symptoms by modulating the actions of the endocannabinoids and also potentiating the effects of serotonin by enhancing the activity of the receptors unto which serotonin binds.
CBD Oil Dosage
Cannabidiol (CBD) oil is becoming more popular as a treatment for a full range of illnesses and issues; however, most people are completely unaware of the various dosages and what is best for their individual situation. In order to use CBD oil responsibly and experience the full benefits of CBD, it is important to make yourself aware of its composition and what that means for your individual ingestion of the substance.
