The term psychological disorders is sometimes used to refer to what are more frequently known as mental disorders or psychiatric disorders.
Mental disorders are patterns of behavioral or psychological symptoms that impact multiple areas of life. These disorders create distress for the person experiencing the symptoms.
The DSM-5-TR lists hundreds of distinct conditions. Anxiety1 and depression2 are among the most common types of mental health conditions that people experience. While the DSM provides diagnostic information about such conditions, including the age at which they typically appear, it does not provide guidelines for treatment or predictions related to the course of illness.
Intellectual Development Disorder
Sometimes called intellectual disability, this type of developmental disorder originates prior to the age of 18 and is characterized by limitations in both intellectual functioning and adaptive behaviors.
Limitations to intellectual functioning are often identified through the use of IQ tests, with an IQ score under 70 often indicating the presence of a limitation. Adaptive behaviors are those that involve practical, everyday skills such as self-care, social interaction, and living skills.
