What Are Cognitive Disorders?
Cognitive disorders cause someone’s brain to process information incorrectly. This results in impaired awareness and judgment, difficulty reasoning and focusing, loss of memory, and abnormal mental capacity. People with cognitive disorders have problems acquiring, mentally organizing, and responding to information, which results in an inability to function normally in everyday life situations.
How Common Are Cognitive Disorders?
Cognitive disorders are particularly common in older populations. The most common of these conditions is Alzheimer’s, which affects more than five million people in the United States. Mild cognitive impairment and non-age-related cognitive disorders, such as various types of amnesia, are less common.
