A clinicopathological study of autism
Brain : a Journal of Neurology
|June 10, 1998
Summary
This study examined brain tissue from individuals with autism, revealing cortical abnormalities and reduced Purkinje cells. Findings suggest the cerebral cortex is likely involved in autism, challenging previous localized theories.
Area of Science:
- Neuropathology
- Neurodevelopmental Disorders
- Autism Spectrum Disorder (ASD) research
Background:
- Investigating the neuropathological basis of autism is crucial for understanding its etiology.
- Previous research suggested localized brain abnormalities in autism.
Observation:
- Examined brain tissue from six individuals with autism and intellectual disability.
- Collected clinical, educational, and parental interview data.
- Observed megalencephaly in four of six brains and cortical abnormalities in four cases.
Findings:
- Identified developmental abnormalities in the brainstem, specifically the inferior olives.
- Noted reduced Purkinje cell numbers and associated gliosis in adult cases.
- Results do not support localized neurodevelopmental abnormality claims.
Implications:
- Suggests significant involvement of the cerebral cortex in autism.
- Highlights the need for further research into cortical contributions to autism.
- Contributes to a broader understanding of autism's neuropathology.

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.
01:27Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
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 the...

01:29Biological Causes of Schizophrenia
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin studies.

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.

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.
