Cognitive disorder

Most common mental disorders affect cognitive functions, mainly memory processing, perception and problem solving. The most direct cognitive disorders are amnesia, dementia and delirium. Others include anxiety disorders such as phobias, panic disorders, obsessive-compulsive disorder, generalized anxiety disorder and post-traumatic stress disorder. Mood disorders such as depression and bipolar disorder are also cognitive mental disorders. Psychotic disorders such as schizophrenia and delusional disorder are also classified as cognitive mental disorders.

Cognitive Mental Disorder Perspective
In abnormal psychology, cognitive disorders are mental disorders that develop on the basis of cognitive mental disorder perspective. The cognitive mental disorder perspective is the theory that psychological disorders originate from an interruption, whether short or long, in our basic cognitive functions, i.e. memory processing, perception, problem solving and language. This perspective takes opposition to the psychodynamic mental disorder perspective, behavioral mental disorder perspective, sociocultural mental disorder perspective, interpersonal mental disorder perspective and neurological/biological mental disorder perspective. One pioneer of cognitive disorder perspective is Albert Ellis. In 1962, Ellis proposeed that humans develop irrational beliefs/goals about the world; and therefore, create disorders in cognitive abilities. Another pioneer of the cognitive disorder perspective is Aaron Beck. In 1967, Beck designed what is known as the "cognitive model" for emotional disorders, mainly depression. His model showed that a blending of negative cognitive functions about the self, the world, and possible selves lead to cognitive mental disorders.
