Objective: Intellectual disability (ID) is considered one of the most common human disorders characterized by significant deficits in cognition and functional and adaptive skills. The aims of this study were to describe the demographic and clinical features of a group of Moroccan individuals with ID living in the Tangier-Tetouan region.
Design: This was a retro-prospective and descriptive exploratory monocentric study realized between November 2020 and August 2023. A total of 109 patients with ID were included. They were selected at four mental health centers in the Tangier-Tetouan region. Our data were treated and analyzed using the IBM SPSS version 26.
Results: A male predominance of patients with ID was observed in our series (54.4% male vs. 42.6% female). The male-to-female ratio was 1.34. The mean±standard deviation (SD) age of our patients was 11.75±4.87 years, ranging from 1 to 35 years. The mean ages of mothers and fathers at the births of their children with ID were 28.36 and 35.6 years, respectively. Many co-occurring medical conditions were noted in our data (speech delay: 20.5%, concentration problems: 15.1%, hyperactivity: 11.1%, ambulation difficulties: 8.8%, aggressiveness: 8%, vision problems: 6.3%, epileptic seizures: 4%). The consanguinity rate was 26.9 percent.
Conclusion: ID associated with genetic causes was significantly correlated with the consanguinity rate in the Moroccan population.

Parental stress can be debilitating for parents and their families. This is particularly true for parents who have a child with autism spectrum disorder (ASD) or other intellectual and developmental disability (I/DD). Effective screening and measurement of parental stress leads to accurate and effective intervention.

Purpose: Heterozygous pathogenic variants in SPAST are known to cause Hereditary Spastic Paraplegia 4 (SPG4), the most common form of HSP, characterized by progressive bilateral lower limbs spasticity with frequent sphincter disorders. However, there are very few descriptions in the literature of patients carrying biallelic variants in SPAST.
Methods: Targeted Sanger sequencing, panel sequencing and exome sequencing were used to identify the genetic causes in 9 patients from 6 unrelated families with symptoms of HSP or infantile neurodegenerative disorder.

The large-conductance calcium- and voltage-activated potassium (BK) channels, encoded by the KCNMA1 gene, play important roles in neuronal function. Mutations in KCNMA1 have been found in patients with various neurodevelopmental features, including intellectual disability, autism spectrum disorder (ASD), or attention deficit hyperactivity disorder (ADHD). Previous studies of KCNMA1 knockout mice have suggested altered activity patterns and behavioral flexibility, but it remained unclear whether these changes primarily affect immediate behavioral adaptation or longer-term learning processes.

Background: Children with intellectual disabilities (ID) typically exhibit low levels of physical activity (PA) and delayed motor skills. Understanding the motor skill factors that influence PA participation in this population is essential for designing effective interventions. The purpose of this study was to examine the association between fundamental motor skills (FMS) and objectively measured PA among orphan children with severe ID residing in welfare institutions.

Variants in KIF1A are associated with hereditary spastic paraplegia (SPG30), which can manifest in both pure and complex forms. We describe a Japanese family with a novel KIF1A variant presenting with a complex form of SPG30. Patient 1, a 69-year-old woman, experienced progressive gait disturbance due to spastic paraparesis and cerebellar atrophy, and intellectual disability.
