There is a huge relation between how a person thinks and how he acts and feels. A Cognitive behavioral therapy (CBT) focuses on exploring relationships among a person's thoughts, feelings, and behaviors. This is one type of an acute mental disorder that a psychologist addresses by working closely with the patient. The psychologist will actively collaborate with the patient by inducing him with a series of one to one sessions. In these sessions, the unhealthy patterns, their destructive behaviors, and beliefs are all addressed, and relevant guidance is given for the same. These sessions also try their focuses on a person's negative feelings and they try to improve them. The primary purpose of a Cognitive Behavioral Therapy Treatment is to concentrate on the psychosocial intervention that is achieved through the various sessions. They typically last between 8 weeks to 6 months. The psychologist addresses different bipolar issues and offers effective treatments for a variety of mental illnesses, including depression, insomnia, eating disorders and schizophrenia. It has been proven that people who undergo treatment for CBT show drastic improvements to their brain activity as this treatment is directed at the brain. Drugs and medications are advised on a case-to-case basis, as one type of drug would not be suitable for the other disorder. Antidepressants are one of the common types of medication that a psychologist might suggest but however, it is advisable to have them only under the guidance of a medical practitioner.
