Summary
Children with autism spectrum disorder (ASD) frequently exhibit minor neurological dysfunctions (MNDs), indicating brain network issues. Neurological assessments are crucial for understanding ASD pathogenesis and guiding interventions.
Area of Science:
- Neuroscience
- Developmental Psychology
- Pediatric Psychiatry
Background:
- Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition.
- Minor Neurological Dysfunctions (MNDs) are subtle neurological signs that can co-occur with developmental disorders.
- Understanding the relationship between MNDs and ASD is crucial for improving diagnostic and therapeutic approaches.
Purpose of the Study:
- To investigate the prevalence and characteristics of Minor Neurological Dysfunctions (MNDs) in children diagnosed with Autism Spectrum Disorder (ASD).
- To compare the neurological profiles of children with ASD to those with other psychiatric disorders and a general population reference group.
- To explore the potential contribution of MNDs to the underlying brain dysfunction in ASD.
Main Methods:
- A cohort of 122 children diagnosed with ASD was assessed for MNDs using the Touwen examination method.
- The ASD cohort was drawn from a larger group of 705 children referred to a psychiatric center.
- MND data from children with ASD were compared with data from children with other psychiatric disorders and a reference population born between 1975-1978.
Main Results:
- A significantly higher percentage of children with ASD (74%) presented with complex MNDs compared to children with other psychiatric disorders (52%) and the general population (6%).
- Common MNDs observed in children with ASD included dysfunctional posture and muscle tone, fine motor difficulties, dyscoordination, and excessive associated movements.
- Statistical analysis confirmed significant differences in MND prevalence across the groups (p<0.001).
Conclusions:
- The findings suggest that dysfunctional supraspinal brain networks play a role in the pathogenesis of ASD.
- The high prevalence of MNDs in ASD supports the link between neurological abnormalities and the disorder.
- Routine neurological examinations are recommended as a valuable component of pediatric psychiatric assessments for children with ASD.

01:19Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

01:12Alterations in Muscle Tone ll
Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...
01:11Alterations in Muscle Tone lll
Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
01:19Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

01:26Modeling in Therapy
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
