Final answer:
The percentage of people with dual diagnosis who received treatment for their mental illness only varies depending on the individual and the specific circumstances.
Step-by-step explanation:
The percentage of people with dual diagnosis who received treatment for their mental illness only varies depending on the individual and the specific circumstances. Dual diagnosis refers to the co-occurring presence of both a mental health disorder and a substance use disorder. It is important to emphasize that treatment for individuals with dual diagnosis typically involves addressing both the mental health disorder and the substance use disorder concurrently, as they often interact and influence each other.
However, in some cases, individuals may receive treatment for their mental illness only. This could be due to various factors such as personal preference, limited resources, or challenges in accessing specialized care for substance use disorders.
To determine the exact percentage of people with dual diagnosis who received treatment for their mental illness only, specific studies or surveys focusing on this specific population would be needed.
