Cognitive disorder

Cognitive disorders are a category of mental health disorders that primarily affect learning, memory, perception, and problem solving, and include amnesia, dementia, and delirium. While anxiety disorders, mood disorders, and psychotic disorders can also have an effect on cognitive and memory functions, the DSM-IV-TR does not consider these cognitive disorders, because loss of cognitive function is not the primary (causal) symptom. Causes vary between the different types of disorders but most include damage to the memory portions of the brain. Treatments depend on how the disorder is caused. Medication and therapies are the most common treatments; however, for some types of disorders such as certain types of amnesia, treatments can suppress the symptoms but there is currently no cure.

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 proposed 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.
