What are psychotropic medications used for?

Psychotropic medications are specifically designed to influence the chemical balance in the brain and, consequently, affect mood, perception, cognition, and other mental processes. These medications play a crucial role in the treatment of various mental health conditions, such as depression, anxiety, schizophrenia, and bipolar disorder, among others. By targeting neurotransmitter systems, psychotropic drugs can help alleviate symptoms and enable better functioning in daily activities.

The other options describe uses that do not align with the primary purpose of psychotropic medications. While enhancing cognitive function or promoting sleep may be secondary effects of certain psychotropic medications, these are not their exclusive functions. Additionally, treating physical injuries is outside the scope of psychotropic medications, which are not intended for physical ailments but rather for mental health issues.
