Causes of Mental Illness


Given that 1 in 5 Americans has a mental disease, it is typical to wonder if mental health issues run in families. Mentally ill people worry that their traits will be passed on to their offspring. People who worry about developing the same issues include people with family who suffer from mental health issues.

But every mental disorder has a variety of causes. While heredity might be a factor, there are other causes of mental diseases. Moreover, a mental disease frequently results from various circumstances coming together, each unique to each individual.

That's why we've carefully researched the real answer with a step-by-step approach to this question.

Causes of Mental Illness

It is challenging to identify the precise origin of mental diseases because of the complexity of psychology. In addition, it is nearly impossible to pinpoint a single cause of mental disease due to the intricate relationship between the mind and the body.

However, medical professionals know that risk factors can alter your propensity to experience mental health problems. For example, society, environment, biology, and genetics can potentially enhance the risk of mental diseases.

Environmental Causes of Mental Illness

Some people might be more likely to acquire a mental disorder if exposed to environmental pollutants or stressors while developing. In addition, the growing fetus may be harmed by maternal illnesses, excessive drinking, drug abuse, or exposure to hazardous chemicals, increasing the risk of mental health issues.

Later in life, various environmental conditions or behaviors may raise your mental disorder risk. Among them are the following:

  • Overuse of drugs or alcohol
  • Chronic disease
  • Trauma to the brain or even another injury
  • Abuse or neglect of children
  • Extreme stress in life
  • Lack of assistance from family and friends

Social Causes of Mental Illness

Socioeconomic position and other social factors may also influence a person's likelihood of having a mental disorder. As an illustration, the World Health Organization (WHO) reviewed the published research on the societal causes of mental disease. They found that 115 papers were examined, and 70% of them indicated a connection between mental problems and poverty.

The methods used in the research to determine poverty, nevertheless, varied. For example, some studies linked higher rates of mental health issues to low income as a measure of poverty. Other research connected mental illness with unemployment, socioeconomic disadvantage, and low educational attainment.

Mental Health Genetic Predisposition

Genes may play a role in the emergence of mental health issues. However, even if you are genetically predisposed to mental illness, you might not experience it.

You might want to discuss any family members with mental health issues with your doctor. Your likelihood of developing a mental disorder increases if you have a close relative who suffers from it. But that does not mean you must develop mental illness.

Genes may express a mental disorder in a variety of ways. Here are some examples of these genetic influences.

Single gene expression: One gene can activate and cause the body to manifest a mental disorder. But cases of mental health issues resulting from this scenario are uncommon.

Epigenetic expression: Depending on the environment and other factors, a gene might express itself or not at different times throughout your life. A gene's expression varies from person to person. Therefore, it is unlikely that you would become mentally ill unless you possess the ideal mix of an active set of genes and additional variables.

Gene polymorphisms: Variations in your DNA that set you apart from others, including your identical twin, are known as genetic polymorphisms. However, despite these variances in DNA, you still require a combination of social, environmental, biological, and maybe genetic elements to develop a mental health issue.

Biological Causes of Mental Illness

Your biology, including your brain's chemical composition, can impact your likelihood of developing a mental illness. Neurotransmitters are chemicals that move information via the brain. These substances and the brain network work adequately in people their entire lives. However, a malfunction in the neurotransmitter-using system can sometimes cause problems like sadness, distress, or other mood disturbances.

Antidepressants and related drugs may be effective for some persons due to the biological causes of mental illnesses. These prescription medicines restore the chemical equilibrium in the brain, which helps some people with the symptoms of mental illness.
