Electroencephalogram and Autism Can the Test Identify the Disorder?

What is the relationship between electroencephalogram and autism ? Recent studies have shown that the test can reveal markers linked to ASD. Including contributing to early diagnosis. However, the observation of alterations without the aid of images and the very complexity of the ASD make it difficult to identify conclusive signs on the EEG. Therefore, clinical evaluation continues to play an essential role in diagnosing autism. In the next lines, I talk about the findings and contribution of the electroencephalogram to the current scenario , in addition to other relevant tests. I also bring tips to optimize neurological reports with telemedicine . What is the purpose of the electroencephalogram in autism? The electroencephalogram in autism serves to assess neuron functioning patterns . To understand the importance of the EEG in this context, it is necessary to recall the characteristics of autism spectrum disorder (ASD) .

Although the word autism is better known

The term ASD best describes this set of neurodevelopmental disorders . According to the Diagnostic and Statistical Manual of Mental Disorders ( DSM-5 ) of the American Psychiatric Association (APA), ASD can be mild, moderate or severe . All classifications have aspects in common, especially difficulties in social interaction, communication and behavior, with repetitive and stereotyped movements. These anomalies are noticed before the age of three , but tend to intensify Canada Mobile Number List as age advances. The causes of ASD are still not entirely clear, however, there are indications that it has a multifactorial origin , resulting from genetic, environmental influence, among others. According to the scientific article “ Autism: neuroimaging ”: “Autism is currently considered an organic brain dysfunction thanks to several evidences. Among these, mental retardation is associated with autism.

Furthermore the risk of recurrence for siblings

Is approximately 3 to 5%, which corresponds to an incidence 75 times higher than in the general population. This, as well as the high prevalence of males in this population (4 to 1), suggest that there is a genetic predisposition to this disorder.” This evidence points to the relationship between ASD DT Leads and brain dysfunction , which includes abnormalities in neuronal electrical activity. That’s where the electroencephalogram fits in , which records electrical impulses in the form of a frequency. During exam activation tests, such as intermittent photostimulation , it is possible to observe responses emitted by certain groups of neurons. And compare this response to normal patterns for the patient’s age. Electroencephalogram detects autism? The EEG offers complementary data, but the diagnosis of autism is clinical . However, the exam’s contribution may soon increase from the identification.
