Introduction to special section: mental retardation and mental illness

Area of Science:

• Psychiatry
• Clinical Psychology
• Developmental Disabilities

Background:

• The historical understanding of mental illness and mental retardation has shifted significantly over two centuries.
• Research and clinical observations for these two conditions have largely progressed independently.
• This separation has limited the integration of psychopathology and treatment within mainstream clinical psychology for affected individuals.

Purpose of the Study:

• To provide current summaries of critical clinical and research issues concerning individuals with both mental retardation and mental illness.
• To initiate a special section focused on the challenges and advancements in understanding "dual diagnoses".

Main Methods:

• This article serves as an introduction to a special section, synthesizing existing knowledge.
• It highlights the need for integrated approaches by reviewing key clinical and research findings.

Main Results:

• Historically, mental illness and mental retardation have been studied in isolation.
• There is a recognized gap in mainstream clinical psychology regarding the mental health of individuals with mental retardation.

Conclusions:

• A dedicated focus is needed to address the complex needs of individuals with co-occurring mental illness and mental retardation.
• This special section aims to bridge the gap by offering updated insights into "dual diagnoses".
