Summary
Genetic and metabolic disorders account for up to 20% of autism cases. Identifying these conditions through genetic testing and metabolic screening aids in understanding autism
Area of Science:
- Genetics and Neuroscience
- Medical Research
Background:
- Advances in genetic technology are expanding the known medical conditions associated with autism.
- Accurate diagnosis of autistic-related syndromes is crucial for tailored clinical counseling.
- Syndromic autism research offers insights into pathogenesis and clinical practice.
Purpose of the Study:
- To review recent advances in autism research.
- To elucidate pathogenetic mechanisms of syndromic autism.
- To discuss implications for clinical practice.
Main Methods:
- Literature search of the PubMed database.
- Keywords used: "autism," "chromosomal abnormalities," "metabolic diseases," "susceptibility loci."
Main Results:
- Defined mutations, genetic syndromes, and metabolic diseases are linked to up to 20% of autism cases.
- Metabolic and mitochondrial defects can cause neuronal damage and alter neurotransmission.
- Chromosomal abnormalities disrupt neural connections, brain growth, and synaptic morphology.
Conclusions:
- Metabolic testing is recommended for specific symptoms.
- High-resolution chromosome analysis is advised for suspected diagnoses with dysmorphisms.
- Whole genome microarray analysis can reveal cryptic chromosomal abnormalities, enhancing understanding of autism's neurobiology.

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.

01:27Psychosis: 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.

01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
01:24Parkinson Disease ll: Pathophysiology
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
01:29Autoimmune Disorders
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.
