[Etiology of mental deficiency. Study based on 3735 cases (author's transl)]
Insights
This study investigated the causes of mental delay (MD) in 3735 children. Pre- and/or peripartum issues were the most common cause, with unknown etiology being rare.
Area of Science:
- Pediatrics
- Neurology
- Genetics
Context:
- Investigated the etiology of mental delay (MD) in a large cohort of 3735 children.
- Emphasized objective patient selection for accurate etiological factor identification.
Purpose:
- To determine the prevalence of different etiological factors contributing to mental delay in children.
- To highlight the importance of comprehensive diagnostic approaches in identifying the causes of MD.
- To advocate for a reduction in the percentage of MD cases with unknown etiology.
Summary:
- Pre- and/or peripartum problems were identified as the leading cause of MD, accounting for 53.78% of cases.
- The study found a low percentage (8.219%) of MD with unknown etiology.
- Recommended integrating clinical knowledge with para-clinical studies (biochemistry, EEG, EMG, cytogenetics, neuroradiology) for accurate MD diagnosis.
Impact:
- Suggests that MD accompanying CNS malformations and dysmorphic syndromes should not be classified as having unknown etiology.
- Stresses the need to consider accurate etiological factor percentages when developing educational programs for children with intellectual disabilities.
- Aims to improve diagnostic accuracy and resource allocation for children with mental delay.
Abstract:
A study on the etiology of MD was done on 3735 children with mental retardation. Selection of patients was verified by precise alphabetical train in order to obtain the different factors of MD with objectivity. The highest percentage of MD was constituted by pathology concerning pre- and/or peripartum problems (53.78%), being on the contrary very low the percentage of MD of unknown etiology (8.219%). Authors think that it is possible to verified correct diagnosis of cases with MD if the clinical knowledge is large the adequate para-clinical studies (biochemistry, EEG, EMG, cytogenetic and neuroradiology) are practised. The unknown etiology of MD must be low. In their opinion MD accompanying CNS malformations and dysmorphic syndromes must not be classified as MD of unknown etiology. Emphasis is done on the necessity of having in consideration real percentages of etiological factors when programs for education of subnormal children are developed.
