Is Mental Illness Hereditary?

Is Mental Illness Hereditary

Mental health is a topic that has been gaining traction in recent years. Whereas once it was taboo to admit to needing professional help, it is now more widely recognized that mental health is just as important as physical health. Experiencing any modality of mental illness can be overwhelming and terrifying. Depending on whether you’re experiencing anxiety, depression, or panic attacks, you may feel like you’re withdrawing, like you can’t breathe or that there’s pressure — you may sometimes even feel like you’re dying. What causes mental illness? Are there any disorders that are hereditary? If so, what is the likelihood of passing it on to your child?

What causes mental illness?

There are several causes of mental illnesses. And, each cause can impact the type of mental illness experienced. The most common causes include:

Prenatal Injury

A person may be born with mental health issues if their mother experienced injury or trauma while pregnant. Other causes of prenatal injury may include consuming alcohol — which can lead to Fetal Alcohol Spectrum Disorders(FASDs) — as well as tobacco, and/or other controlled substances.

Infections

When the body has an infection, the immune system is activated to fight it. However, when the inflammation caused by the infection is chronic, the response of immune system cells may also cause damage to healthy brain tissue.

Trauma

Trauma encompasses many aspects of human health — including abuse, emotional, sexual, or physical. Any event that causes physical or emotional injuries can lead to anxiety disordersPTSDborderline personality disorder, and/or depression.

Substance Abuse

Approximately half of all individuals with mental health issues also experience substance abuse and vice versa. Substance abuse can also lead to addiction, which is often accompanied by depression. Developing both disorders often results in a dual diagnosis of mental illness.

Environmental Factors

Your lifestyle and environment can contribute to your mental health. Pollution, long-term exposure to toxins — found in food treated with pesticides and/or antibiotics, the environment, personal hygiene products, and detergents — sleep deprivation, substance abuse, and/or hazardous conditions at your place of employment can all lead to mental illness.

Genetics

The likelihood of developing a mental illness is higher for individuals with a family history of that same disorder. That being said, symptoms could range from mild to severe — even to a different degree than how it affected your family member. How your genes express themselves — epigenetics — will also determine whether you’ll develop a hereditary condition.

What is the likelihood of passing on mental illness to your child?

Although genes are certainly a risk factor, the development of mental illness doesn’t have to be your child’s destiny. For these genes to manifest a mental health condition, they have to encounter the right combination of epigenetics and environmental factors. Factors that can influence this include lifestyle, environment, and/or underlying health conditions.

One of the mental illnesses that is most likely to run in families is bipolar disorder. If one parent has the condition, their child has between 15% and 30% likelihood of developing it. If both parents are bipolar, the probability skyrockets up to 75%. It’s also possible for the child of a parent with mental health issues to experience trauma during childhood, increasing their own likelihood of developing other types of mental health issues in the future.
