Final answer:
Millions of people take medicine they don't need for a diagnosis of MDD that they don't really have on the false assumption of a correct diagnosis.
Step-by-step explanation:
The false assumption in this question refers to the incorrect belief that individuals have a diagnosis of Major Depressive Disorder (MDD) when they don't actually have it. This assumption leads millions of people to take medicine they don't need for MDD.
MDD is a common mental disorder characterized by a severely depressed mood lasting longer than two weeks along with other symptoms like loss of enjoyment in activities, changes in appetite and sleep, difficulty concentrating, and feelings of worthlessness. The exact causes of MDD are unknown, but they likely include both genetic and environmental factors.
Treatments for MDD include psychotherapy, electroconvulsive therapy, deep-brain stimulation, and prescription medications, such as antidepressants. However, it is essential to have an accurate diagnosis and consult with a healthcare professional before starting any medication.
