Autism Spectrum Disorder01:19

Autism Spectrum Disorder

956
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.

Major Somatic Sensory Pathways

2.4K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

1.8K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Area of Science:

  • Neuroscience
  • Genetics
  • Developmental Biology

Background:

  • Autism spectrum disorder (ASD) is a prevalent neurodevelopmental disorder with complex genetic and environmental origins.
  • While research has focused on cortical and hippocampal regions, emerging evidence highlights the cerebellum's consistent association with ASD.
  • The cerebellum, traditionally linked to motor control, also influences cognitive, sensory, and behavioral functions through its connections to non-motor brain areas.

Purpose of the Study:

  • To review the cerebellum's role in ASD development.
  • To focus on genetic variations implicated in ASD, specifically those expressed and studied within the cerebellum.
  • To categorize ASD-associated genes based on discovery methods (candidate gene vs. unbiased genetic analyses).

Main Methods:

  • Literature review of studies on cerebellar function in ASD.
  • Categorization of ASD-associated genes into candidate and unbiased discovery groups.
  • Inclusion of recent findings on non-genetic factors interacting with genetic predispositions.

Main Results:

  • The cerebellum plays a critical role in ASD.
  • ASD-associated genes are classified into two main groups: candidate genes with confirmed cerebellar links and genes identified through unbiased genetic analyses.
  • Non-genetic factors interacting with genetic factors in ASD etiology are also discussed.

Conclusions:

  • The cerebellum is a key brain region implicated in ASD.
  • Understanding cerebellar gene expression and function is crucial for deciphering ASD's genetic underpinnings.
  • A comprehensive view integrating genetic and non-genetic factors is essential for advancing ASD research.
