Biological Factors Influencing Mental Health

Most mental disorders are caused by a combination of environmental, psychological, and biological factors. Moreover, some of these conditions are connected to the unusual functioning of nerve cell pathways or circuits connecting a specific brain part. Nerve cells based in these brain circuits use neurotransmitter chemicals to communicate. Altering these elements using psychotherapy, medicines, or medical procedures may help the brain circuits to function more efficiently. Here are some of the biological factors involved in mental illness development.

Genetics or Heredity

Sometimes, mental disorders are common in some specific families. This suggests that individuals from those families are more likely to develop these conditions. The vulnerability of mental health issues can be passed from one generation to another through genes. Experts suggest that mental disorders are connected to abnormalities in several genes, and how these genes interact with their surroundings differs from one person to another. Therefore, a person may inherit a vulnerability to a mental disorder but fail to develop the condition. However, abuse, traumatic events, or stress can trigger or influence a mental illness.


Some infections have been connected to brain issues and the development of mental disorders or deterioration of its symptoms. For instance, a condition referred to as pediatric autoimmune neuropsychiatric disorder linked to the streptococcus bacteria has been connected to obsessive-compulsive development and other mental disorders in kids.   

Substance Abuse

Long-term drug abuse can lead to anxiety, paranoia, and depression. Alcoholism is also a major concern in a person’s mental health. Besides, an unhealthy diet and exposure to toxins like lead also play a role in mental illness development. Staying away from substance abuse and eating a balanced diet and products like broad spectrum CBN soft gels reduces the likelihood of developing mental complications.

Biological and environmental factors play an essential role in a person’s mental health. Although some of these conditions may be heredity, a person’s lifestyle can increase their vulnerability.
