What are the Causes of Major Depressive Disorder?
Till date , researchers do not on the nose know the grounds as to why some people develop Major Depressive Disorder and some only develop mild to moderate depression . The following factors are believed to play a role in causing Major Depressive Disorder :
Hormonal Imbalances- It ’s believed that sure changes in the levels of hormones or the balance wheel of hormones in the body , especially during and after gestation , or duringmenopausemay trigger Major Depressive Disorder in some woman.(1 )
Genetics- People who have a sept story of Major Depressive Disorder are more potential to develop Major Depressive Disorder than others.(2 )
Stress – eminent levels of stress or a stressful life history outcome , such as the death of a make out one or a divorcement , can also lead to an episode of Major Depressive Disorder.(3 )
Biochemical Reactions- Chemicals that are present in the brain of citizenry having Major Depressive Disorder have been observed to function other than than those in the brains of people who do not have this upset .
How Does Depression Affect the Brain?
There are three parts of the brain that are known to show some distinct characteristics in citizenry who hurt from clinical depression . This is believed to have a part to play in the ontogenesis of Major Depressive Disorder .
Hippocampus- The genus Hippocampus is the part of the brainiac that stores computer storage and is also responsible for for producing a hormone known as cortisol(4 ) . find at the center of the brain , the hippocampus releases cortisol when the trunk undergo strong-arm or genial stress . During times of extreme strain or during a chemical dissymmetry , the genus Hippocampus can release extra amount of Cortef . The release of extravagant cortisol in low causes the neurons in the hippocampus to shrink , slowing down the yield of new neurons . This is believed to be the rationality why so many citizenry having depression struggle with concentration and memory .
Prefrontal Cortex : The prefrontal lens cortex is located at the front of the brainiac . The prefrontal cortex is the part of the brain that regularise emotion and is also involved in memory formation and decision making.(5)When there is an excessive output of cortisol by the hippocampus , the prefrontal cortex also shrinks in Great Depression .
Amygdala- The amygdala allow you to find emotions such as care or pleasance . Once the hippocampus releases excess amounts of Hydrocortone , in people having depression or Major Depressive Disorder , we abide by an magnified and hyperactive amygdaloid nucleus due to being divulge to constant high levels of cortisol . This can raise up your sleep design and also cause the body to release imbalanced amounts of other chemicals and hormones that can lead to other types of issue .
Research believe that such gamey levels of cortisol have a big role to toy in changing the genuine physical structure as well as the chemical action of the brain , which is what trigger the onset of natural depression or Major Depressive Disorder . In people who do not have Major Depressive Disorder , cortisol levels are at their peak in the morning and then diminish by the Nox . However , in mass having Major Depressive Disorder , hydrocortisone degree remain elevated at time even during the night .
Can Treatment Help Depression and Reverse the Effects of Depression on the Brain?
Studies have found that by equilibrate the spirit level of hydrocortisone along with other chemical substance in the mind , it is potential to reverse the shrinkage of the hippocampus and any other character of the brain.(6)This can treat remembering problems that economic crisis might have caused and help in compensate the chemical substance grade in the body can also depress some of the symptoms of Major Depressive Disorder .
There are many medicinal drug that campaign off the negatively charged wallop of depression on the brain and help repair the counterbalance of chemicals in the genius and also help in reversing the affects of depressive disorder on the mentality . Some of these mutual medicine include :
SSRIs ( Selective Serotonin Uptake Inhibitors)- SSRI are medicine that help provide reliever in the symptoms of Major Depressive Disorder by make a variety in the level of a compound known 5-hydroxytryptamine in the brain.(7)Some commonly used SSRIs admit Paxil ( paroxetine ) , Celexa ( citalopram ) , and Prozac ( Prozac ) .
Tricyclic Antidepressants and SNRIs ( Serotonin - Norepinephrine Reuptake Inhibitors)- When used in combination , both these medications are known to alleviate Major Depressive Disorder symptoms , as they change the amounts of norepinephrine and serotonin in the brainiac . Both these chemical are known to boost vim and temper point . Some common SNRIs include Cymbalta ( duloxetine ) and Effexor XR ( venlafaxine ) . Tofranil ( imipramine ) , Surmontil ( trimipramine ) , and Pamelor ( nortriptyline ) are some commonly used examples of tricyclic antidepressant drug , which facilitate ease depression .
MAOI ( Monoamine Oxidase Inhibitors)- These medications help provide relief in the symptom of Major Depressive Disorder by boost the levels of serotonin , norepinephrine , and dopamine in the brain . Monoamine Oxidase inhibitor also help in improving brain cell communication .
NDRIs ( Norepinephrine - Dopamine Reuptake Inhibitors)- Norepinephrine - Dopamine Reuptake inhibitor facilitate Major Depressive Disorder martyr by increasing the levels of dopamine and noradrenaline , both of which are mode - boost compounds in the brain . Wellbutrin ( bupropion ) is a common NDRI that is dictate by doc for discourse of depression .
Atypical Antidepressants- This course of study of drugs includes mood stabilizers , neuroleptic agent and tranquilizer . Atypical Antidepressants work by blocking brain cell communication , which allow the trunk to relax .

Transcranial Magnetic Stimulation ( TMS)- Transcranial Magnetic Stimulation is a process that need sending electrical pulses directly to the learning ability cell for regulating mood .
Electroconvulsive Therapy ( ECT)- Electroconvulsive Therapy involves passing electric flow throughout the brain in monastic order to increase the spirit level of communication between the brain cells , which aid with clinical depression .
Researchers and experts also believe that psychotherapeutics also has a role to act in alter the structure of the brain , thus relieving the symptoms of Major Depressive Disorder . Psychotherapy especially helps in strengthen the prefrontal lens cortex of the brainiac .
Conclusion
Boosting encephalon wellness is one way to help recover and manage the symptoms of Major Depressive Disorder without any medical intervention . However , please keep in nous that after a sure level , depression can only be care for with the help of medications and therapy . Some way you may boost your brain wellness let in :
