It is a neuropsychiatric disorder expressed in the emotional, physiological, and behavioral effects.
Depression is common, chronic, and severely damages the quality of life, often leading to risk due to suicidal tendencies. More than 12% of the US population suffers from depression.
The brain’s reward system is the neuronal circuit related to emotional phenomena such as hedonism and depression and includes brain centers and pathways activated by natural and artificial rewards.
The most important cerebral reward centers, such as the nucleus accumbens, the ventral tegmental area, and the ventral prefrontal cortex, are found at depths of 3-7 cm inside the brain.
Symptoms of depressive disorder
Due to the debilitating effects of depression, many people suffer from the disorder for weeks, months, or even years before seeking effective treatment. However, there are specific symptoms that people and their loved ones can observe to determine if depression is affecting their lives.
Some common psychological symptoms of the depressive disorder include:
- Unexplained sadness, frustration, or irritability.
- Decrease in interest in previously enjoyed activities.
- Difficult to focus.
- Feelings of guilt.
- Suicidal ideas.
The typical physical manifestations of major depression may include, but are not limited to:
- Headaches, back pains, and other body aches.
- Crying spells are not invoked.
- Sudden changes in eating habits with a decrease or increase in appetite.
- Loss of energy
- Problems sleeping or insomnia.
- Get help for major depression.
Suicidal ideas are often indicative of the need for immediate attention from a doctor or mental health professional. Anyone who has thoughts of suicide or hurting others should call a psychiatrist or 911 for immediate help.
Fortunately, major depression can often be treated with conventional psychiatric treatments, such as medication and psychotherapy.
However, up to a third of patients do not have an adequate response to these treatments. In addition, conventional medical treatments can take months or years to be effective and often end in relapses.
Transcranial Magnetic Stimulation (TMS) has shown remarkable results in the treatment of significant depression safely and effectively and in a fraction of the time compared to conventional therapies.
EMT treats depression by activating specific regions of the brain that become inactive in a depressed patient.
After repeated sessions of EMT, the brain adjusts its activity, reducing depression. In this way, patients can overcome their depression without the adverse side effects of the medications and in a shorter period than the counseling treatments.
Causes of depressive disorder
There are numerous causes of major depression, according to doctors and researchers. Some of these causes can arise organically within an individual, while others come from environmental events that affect the person.
The wide range of potential causes has led to numerous treatments for depression.
A change in brain activity is almost always associated with a major depressive disorder. There is decreased activity in the left frontal lobe during the depression and increased exercise after mood stabilization.
These discrepancies between the hyperactive and sub-active regions of the brain are the biological cause of the major depressive disorder.
Neurotransmitters could cause depression.
The release and reuptake of neurotransmitters (serotonin, norepinephrine, and dopamine) in the brain are related to a person’s mood.
Depression has been linked to the imbalance of these neurotransmitters (NT). Still, unfortunately, it is difficult to prove since it is tough to measure the concentrations of these NTs in the brain. What is known is that antidepressants act on these NTs and their receptors.
Childhood trauma often causes severe depression.
Childhood trauma can cause a person to become depressed for a prolonged period.
Examples of such traumas are serious illness; isolation; physical, sexual, or mental abuse; witness a traumatic event; and negligence. Regardless of the trauma, childhood experiences are one of the most common causes of major depression.
Major life events can cause severe depression.
Losing a loved one, taking a high-stress job, and facing difficult financial situations are known causes of depression. However, in many cases, depression is short-term.
Once the person has gone through the grieving process, straightened out their financial problems, or learned to manage work stress, depression can begin to resolve itself. In these cases, therapy can be beneficial for a faster recovery.
Hormonal changes can lead to depression when rapid hormonal changes are one of the causes of major depression, for example, in women entering menopause.
Treatment of the depressive disorder
Drug therapy and counseling are two of the most popular forms of primary depression treatment. While they are often quite effective, they are not the only options available. Transcranial Magnetic Stimulation has shown excellent results in the treatment of depression.
EMT for major depression uses focused electromagnetic waves to activate specific brain regions.
EMT normalizes the neuronal circuit that causes depression so that the symptoms of depression are resolved. The results persist after an entire course of EMT treatment. A response to EMT can be seen in just two weeks.
Since the treatment is not systemic, there are no undesirable side effects experienced by the patient, as with medications.
Traditional alternatives for the treatment of major depressive disorder include pharmacological therapy and electroconvulsive therapy (ECT). In addition to these two methods, patients with depression are treated with psychotherapy.
However, this treatment for depression usually accompanies one of the two treatments mentioned above. It should not be used as an exclusive treatment, except in relatively mild cases, since reports indicate its effectiveness is quite limited.
There are several antidepressant medications designed to treat major depressive disorder.
The main classes of antidepressants are the selective serotonin reuptake inhibitors (SSRIs) and the serotonin and norepinephrine reuptake inhibitors (SNRIs), which include Prozac type drugs, as well as other newer antidepressants.
These drugs affect additional neurotransmitters that may involve depression, such as dopamine.
Psychotherapy is usually used to increase drug therapy or ECT to treat depression. Psychotherapy alone is not recommended for patients with moderate or severe depressive episodes but only for mild cases of depression.
Psychotherapy is, by its very nature, a prolonged process; Its success is by no means safe or scientifically proven and depends mainly on the therapist’s skill.
However, research has shown that psychotherapy and support groups may influence the ability of patients to continue drug therapy.
Electroconvulsive therapy (TEC)
Electroconvulsive therapy is usually administered in cases of severe depression, in which drug therapy is ineffective or is not an option, and in which depression directly threatens the life of a patient. ECT has advanced in recent years and is now administered under general anesthesia with muscle relaxation.
