Summary
Understanding the causes of mental retardation (MR) is crucial for public health. This review details current diagnostic investigations for identifying the etiology of developmental delay and MR.
Area of Science:
- Medical Genetics
- Neurology
- Developmental Pediatrics
Background:
- Mental retardation (MR) affects 1-10% of the population, posing significant public health challenges.
- The etiopathogenesis of MR is complex and often poorly understood, complicating diagnosis.
- Early diagnosis is key, with MR defined by cognitive and adaptive impairments before age 18.
Purpose of the Study:
- To review essential investigations for determining the etiology of developmental delay/MR.
- To provide recommendations for the clinical evaluation of patients with undiagnosed MR.
- To highlight advancements in diagnostic techniques since 1997.
Main Methods:
- Review of current literature and diagnostic guidelines.
- Focus on cytogenetic studies and neuroimaging.
- Emphasis on molecular cytogenetics and advanced neuroimaging techniques.
Main Results:
- Cytogenetic studies and neuroimaging are highly valuable in specific clinical contexts.
- Advances in molecular cytogenetics and neuroimaging have increased diagnostic yield.
- New disorders associated with MR have been identified and defined.
Conclusions:
- Appropriate investigations are necessary to define the etiology of DD/MR.
- Clinical evaluation should incorporate updated diagnostic recommendations.
- Continued research is vital for understanding MR etiopathogenesis.
