Is Depression Genetic: Symptoms, Causes, Treatment & Myths Debunked

Is Depression Genetic?

According to many scientific studies and research, it has been proven that genetic factors do play a role in Depression. Most studies to know whether Depression is genetic involve studies in twins. They study the pattern of illness in the twins, i.e., if a twin has Depression and if it is caused because of genetics, their twin will also have the risk of Depression. 

According to a Stanford Medicine data, in most cases of depression around 50% cause is genetic owing to heritability which is around 40-50%.

However, there is no visible pattern or concrete validation that Depression is only caused because of genetic factors. It is suggested that Depression is a result of various factors: genetic, psychological, social, etc. According to studies, variations in genes, with the slightest of effects, combine and increase the risk of developing Depression.

Research also shows that genes associated with Depression control various brain functions. Among these are neurotransmitters that control the production, transport, and activity of chemicals that relay chemical signals that allow nerve cells (neurons) to communicate with one another. Genes responsible for the growth, maturation, and maintenance of neurons may also influence the risk of Depression. 

What is Depression?

Depression is a common type of mood disorder where individuals suffer from feelings of persistent sadness, hopelessness, worthlessness, and lack of interest in everyday activities. Most people may misunderstand Depression as an episode of sadness and mood swings. However, it goes beyond emotions and mood's general ups and downs. 

The feeling of sadness remains persistent for as long as more than two weeks in individuals dealing with Depression. It also manifests in changed sleeping patterns, such as insomnia (loss of sleep) or hypersomnia (excessive sleep). Additionally, people with Depression also most often feel a lack of interest in things or activities that they previously may have enjoyed.

Depression and its severity, like any other mental health issue, can vary depending upon individual experiences. Likewise, symptoms also vary depending on individual experiences and the type of Depression they may be dealing with. Various types of Depression include major depressive disorder, depressive disorder, persistent depressive disorder (dysthymia), bipolar disorder, and seasonal affective disorder, among others.

What Exactly Causes Depression?

With Depression, there is no one-size-fits-all cause but a combination of multiple factors. Depression is, after all, a complex mental health issue. Some of the key contributors to the development of Depression are: 

• Genetic Factors, including genetics and family history, increase the risk of developing Depression. 
• There may also be Biological causes of Depression, such as imbalances in chemical messengers in the brain, changes in the levels of serotonin, dopamine, and norepinephrine, etc.
• Brain Structure and Function, i.e., abnormalities in some brain regions, such as the hippocampus, amygdala, and prefrontal cortex, may affect an individual's moods, eventually increasing the risk of Depression.
• Hormonal Changes because of stress or changes in reproductive hormones(especially in women) can also contribute to depressive symptoms.
• Environmental Factors, including life transitions, trauma, the loss of a loved one, financial difficulties, relationship problems, or work-related stress, can also often contribute to Depression. 
• Psychological Factors such as an individual's personality traits, coping styles, and negative thought patterns can influence the development of Depression.
• Chronic medical conditions such as diabetes, cardiovascular disease, and autoimmune diseases increase the risk of Depression with their physical manifestations. 
• Substance abuse, including alcohol and drug abuse, can also aid in Depression. Sometimes, people dealing with Depression may rely on substance abuse as an escape and worsen the condition, and this may even become cyclic. 
• Medications and specific Treatments can also lead to developing depressive symptoms as a side effect of heavy medications and treatments, especially concerning chronic illnesses. 
• The interaction between genetic predisposition and environmental factors is crucial. While genetics may increase susceptibility, environmental stressors often play a key role in triggering the onset of Depression.
