Biological psychiatry is both a modern phenomenon and a view that has existed for many years. In the present, psychiatrists know that many mental illnesses have a biological component. However, there are a few differences between regular and biological psychiatry, lying in this specialty's philosophy, goals, and approach to addressing mental health symptoms. To understand psychiatry, it can be essential to understand these differences.

What Is Biological Psychiatry? 

Biological psychiatry posits that mental illnesses are brain disorders that should be treated through an interdisciplinary approach featuring biological, psychological, and social interventions while relying on scientific research. Physical sciences that can contribute to biological psychiatry include neuroscience, psychopharmacology, biochemistry, physiology, and genealogy. 

Biological psychiatry emphasizes the connection between brain functions and behaviors. The goal is to prove that physical factors can cause mental health disorders. As a result, psychotropic medications and other medical interventions may play a significant role in biological psychiatry.

Tools For Biological Psychiatry

Biological psychiatry uses various tools to inspire theories, conduct research, and diagnose mental illnesses, including the following. 

Mathematics 

Mathematical advances in theoretical physics have significantly impacted the study of mental health disorders. As using findings to compute various effects and develop theories based on those results becomes more ingrained in the scientific community, many biological psychiatrists are moving towards using math to develop theories in their field.

Computational models have already been used to develop theories related to:

• Learning

• Emotions

• Dopamine signaling

• Information processing

Health Records

Electronic health records are used to discover the biological bases of various mental conditions. Earlier, symptoms were identified using doctors' notes in electronic records. However, more recently, scientists have developed ways of finding sets of symptoms and the dimensions of the symptoms to present a more comprehensive view of the patient's situation automatically. 

The Case-Control Method

Some biological psychiatry researchers use case-control to study the link between mental health and biological factors. This method compares the case files of a person with a mental health disorder with a person without one. Its goal is to understand the natural differences between individual cases of mental health disorders and the differences between those with and without a mental illness. 

Genetics

As more resources that make studying genetics and how they can connect to mental health become accessible, there may be an uptick in the number of studies that target this area. Biological psychiatry is one of the fields that may pursue research of this sort, particularly due to its focus on how the structure and function of the brain can influence symptoms.

Advanced Neuroimaging Technology

As medical testing advances, new ways of assessing brain changes and viewing brain function are becoming available. Some studies use functional MRI (fMRI) to watch the brain and correlate the brain function to brain biology.

Research Domain Criteria

Since the Diagnostic and Statistical Manual (DSM) was released in 1952, psychiatrists have referred to it and its subsequent editions when diagnosing mental disorders. More recently, the National Institute of Mental Health has begun to develop the Research Domain Criteria.

This research framework is designed to help researchers explore mental illnesses while considering biological factors. The DSM-5 and other diagnostic tools are often essential to the mental health field. However, the Research Domain Criteria publication offers a view of mental health disorders that may be more compatible with biological psychiatry.

Biological Bases For Specific Mental Disorders

Breakthroughs in biological psychiatry research have uncovered biological bases for a wide range of mental disorders. With the new emphasis on healthy brain function, more research may follow the same trends. Below are some of the most significant discoveries that have come about in recent decades related to the connection between biology and mental health.

Bipolar Disorder 

Research on the bases of bipolar I disorder and bipolar II disorder, two individual subsets of bipolar disorder, has indicated that bipolar II disorder is not a milder form of bipolar I disorder, as it was initially argued. Instead, those with bipolar I disorder and bipolar II disorder were found to have different genetic makeups. While the genetic factors that may lead to each disorder are similar, the overlap of the genetic code is partial.

Additionally, the occurrence of bipolar I disorder was more likely in families who had schizophrenia. This factor has not been found true for bipolar II disorder. While these two disorders are related, they are more distinct than initially assumed.

Schizophrenia

In a recent study, researchers found that the gene groups associated with schizophrenia can cause specific changes in the brain. If these genes are altered, the neurons behave differently. This biological factor may be essential in discovering the causes of schizophrenia and devising medical treatments for it.

Depression

A new study conducted at the University of Warwick, UK, used neuroimaging to discover links between changes in the brain's reward and memory systems and depression. Further research must be conducted to uncover which brain regions are involved in losing happiness and pleasure.

Psychotic Disorders

Biological psychiatry research offers new possibilities for diagnosing psychotic disorders more accurately. Along with improved diagnostics may come more effective treatments as well. In one study, 700 patients with symptoms of psychosis were assessed using medical testing, including MRI and tests requiring participants to respond to sensory cues. The results showed more accuracy than the DSM. With more research, there is hope that medical testing may be used along with the reports of symptoms now used for more precise diagnosis.

General Risk For Mental Illness

One study found a biological risk factor for various mental health disorders. The connectivity between the visual centers of the brain and the centers used for complex thoughts was different in people with mental health disorders than those without. This research may inspire new prevention techniques for at-risk individuals.

How Can Biological Psychiatry Help?

Biological psychiatry can potentially help people with mental illness now and in the future. Below are a few benefits of a biological approach to mental health treatment. 

Prevention

By delivering clues about the causes and risk factors of mental health conditions, biological psychiatry research may open the door to more effective prevention techniques. As medical testing for mental illness advances, more people may be able to know they're at risk before symptoms appear, which might allow biological psychiatrists to treat mild concerns before they become serious. 

Finding An Effective Medication 

Medications are often used to treat symptoms of mental illness. However, treatment with psychiatric drugs is often subject to trial and error. As biological psychiatry progresses, finding the proper medications for a specific person may become more approachable and specific. In some cases, advancements in this area have already been made, with some doctors being able to offer a genetic test to see which medications may be most effective for an individual. 

Treatment Planning 

Although advances in the medical aspects of biological psychiatry may support medical treatments, non-biological treatments can also have a vital place in supporting those with a mental illness. A skilled psychiatrist can create a treatment plan that combines biological and psychological interventions to improve outcomes dramatically.

The Benefit Of Psychotherapy 

Despite the increasing knowledge about the biological processes of mental disorders, psychology is an essential factor in mental health. Coping with thoughts and behaviors through therapy may continue to be a core part of treatment in the long term. If you're seeking support or guidance, talking to a therapist can help you determine what treatment you might benefit from. In addition, you don't need a mental illness to receive support. 

If you face barriers to in-person therapy, such as a lack of insurance, low income, or inaccessible options in your area, online therapy through a platform like BetterHelp can be an effective way to receive support. By using the web for therapy, you can get matched with a therapist specializing in your unique concerns. In addition, you can choose between phone, video, or live chat sessions with your provider.  

A recent review of studies focused on online cognitive-behavioral therapy (CBT) found it could be significantly effective in treating depression, anxiety, post-traumatic stress disorder, and other mental health conditions.
