Final answer:
Physicians specializing in psychological disorder treatment and who can prescribe medication are known as psychiatrists.
Step-by-step explanation:
Physicians who specialize in the treatment of psychological disorders, earn an M.D. and focus on more severe disorders like schizophrenia are known as psychiatrists. Psychiatrists are medical doctors who, after attending college and medical school, undergo specific residency training in psychiatry, enabling them to diagnose and treat mental health conditions. They have the unique ability to prescribe medications and manage the biological aspects of psychiatric disorders, alongside psychotherapy, which sets them apart from psychologists, who may conduct therapy but do not prescribe medication.
