Can Mental Health Be Genetic?
Researchers have found a number of genes that may be involved in bipolar disorder, schizophrenia, major depressive disorder and other mental illnesses.
Scientists have found a number of genes that may be involved in bipolar disorder, schizophrenia, major depressive disorder and other mental illnesses.
Genes are chemicals that contain instructions for how to make proteins. Proteins are the building blocks of our bodies; they help keep us healthy by doing everything from making hormones to transporting substances through our bloodstreams. Genes also support healthy brain chemistry and influence how we respond to stress.
Your genes do not guarantee that you will develop a mental health condition, but they may increase your risk. Some people with one or more genetic risk factors never develop any problems; others have symptoms without having any problems related to their genes (for example, if there is no family history of mental illness). There are many factors involved in developing these conditions—the environment where you live, what medications you take or don’t take—and understanding this can help improve treatment outcomes for those affected by them.
Some genes are related to brain chemistry. Other genes play a role in how people respond to stress or life events.
Some genetic variants are related to brain chemistry. Other genes play a role in how people respond to stress or life events. For example, some people may have a specific gene that makes them more likely than others to experience severe anxiety when going through stressful situations.
In addition, research has shown that some people inherit certain conditions from their parents because they carry the same gene mutations that caused those conditions in their parents. However, having one of these inherited conditions doesn’t mean you’ll develop it yourself—it simply increases your risk of developing a disorder if you have other predisposing factors (such as stress or environmental exposure).
But a genetic predisposition doesn’t guarantee you’ll develop mental illness.
But it’s important to remember that a genetic predisposition doesn’t guarantee you’ll develop mental illness. In fact, research has found that the more genetic predispositions you have, the more likely you are to get the illness.
So if your parents had mental health issues and they passed them down to you, it’s possible that those genes could have made their way into your DNA and be affecting how your mind works now—but they don’t necessarily mean that fate is inevitable.
Mental illness doesn’t always run in families, but it can.
While it’s true that some mental health problems can be hereditary, genetics cannot explain all the causes. In fact, most people with a vulnerability to developing certain conditions do not develop them.
More than 95% of the time, environmental factors are responsible for causing mental disorders in individuals who have an increased risk of having these disorders. Therefore, studies have indicated that there is no gene or combination of genes responsible for causing all mental illnesses. Instead, it appears that different variants of specific genes predispose people to different types and amounts of vulnerability to developing certain kinds of mental health problems.
It’s probable that some people are more susceptible to developing certain types of symptoms due to their genetic makeup (for example: depression), while other people may not show any signs despite carrying similar mutations in their DNA (such as schizophrenia).
The interaction between genes and environment plays an important role in determining whether someone develops a particular illness or disorder like anxiety or bipolar disorder—two examples where research has shown higher rates among family members compared with unrelated individuals living under similar conditions—and this relationship is complicated by how much control each person has over their lifestyle choices such as dieting habits (which may affect weight gain), smoking habits etc.
For each child born, the risk of mental illness is 50 percent less than it was for the parent. The risk drops even further after that.
The risk of inheriting a mental illness from your parent doesn’t just apply to your genes. It can also apply to the environment you grew up in, as well as any other factors that affect the way your genes behave. For example, if your mom drinks too much alcohol during pregnancy, she may increase her baby’s risk of developing an alcohol-related disorder later on.
But there are times when genetics really do play a role and lead to an inherited disease or condition. For example:
- Fragile X syndrome is caused by a single gene mutation that leads to intellectual disability and autism spectrum disorders in boys who inherit it from their mother (though girls can also get it).
- Cystic fibrosis is caused by mutations in two genes related to salt balance function—one on each chromosome (the X chromosome and one of our two sex chromosomes).
Your genetics can make it more likely you will have mental health problems but that does not mean that you will definitely get them.
It is important to remember that your genetics are not the only factor in determining whether you will develop mental health problems. Your environment, experiences and other factors affect how your genes are expressed — this means that even if certain genes increase your risk of developing a condition, they may not play an important role if other factors reduce it.
For example, someone who has a genetic variant which increases the risk of schizophrenia might have an increased chance of developing the condition compared with someone without this variant but who lives in an area where there’s less access to services or low levels of social support. Another person without such a genetic variant may still develop schizophrenia because their social circumstances mean they’re exposed more often than average to stressful events (the World Health Organization defines stress as anything that gets in the way of you living a peaceful life). Genes aren’t always – most definitely, rarely, the cause for someone to be diagnosed with a mental illness of any sort. Keep that in mind. Remember that you are not your parents nor the atmosphere you’ve grown in.
