Clinical psychology is concerned with the actual treatment of mental disorders and problems. There are several places for treatment of mental disorders such as mental hospitals, psychiatric wards in general hospitals, nursing homes and halfway homes. Psychotherapy is characterized by restructuring the way a person behaves, feels and thinks to solve the person's specific problem without the use of drugs or other biological treatments. Similar to Freud's psychoanalysis theory, psychodynamic theory emphasizes that mental disorders are caused by unconscience thought.
Humanistic therapy involves bringing out feelings and restoring confidence to the patient.
The major methods of biological therapies used to alter thinking and behavior are drugs, electroconvulsive shock therapy and psychosurgery. Drug therapies work by blocking certain neurotransmitters in the brain. Electroconvulsion therapy sends an electrical pulse through the brain. Psychosurgery removes or destroys parts of the brain.
