Psychotropic medication, psychiatric disorders, and higher brain functions

Area of Science:

• Neuroscience
• Psychiatry
• Pharmacology

Background:

• Current psychiatric diagnosis relies on symptom description, guiding psychotropic medication choice.
• This descriptive method is compared to pre-microbiology era diphtheria diagnosis.
• Advances in neuroscience necessitate a new analytical framework.

Purpose of the Study:

• To propose an intermediate analytical level between psychiatric symptoms and drug action.
• To reframe psychiatric symptoms as higher brain dysfunction.
• To view psychotropic drugs as modulators of normal brain functions.

Main Methods:

• Analyzing psychiatric symptoms based on abnormal higher brain functions.
• Utilizing a case study of obsessive-compulsive disorder (OCD).
• Examining psychotropic drugs' effects on higher brain functions.

Main Results:

• OCD symptoms point to dysfunctions in working memory, emotional regulation, voluntary control, and self-awareness.
• Psychotropic medications can be understood as agents that modify higher brain functions, such as enhancing social bonding.
• This approach offers a new perspective on treating conditions like depression.

Conclusions:

• Psychiatric illness should be reclassified using clinical neuroscience knowledge.
• Treatment targets for psychotropic medications need revision based on brain function.
• Integrating neuroscience advances will improve psychiatric diagnosis and treatment.
