Summary
Autism spectrum disorder (ASD) frequently co-occurs with selective mutism (SM) in children. Children with both conditions often experience later symptom onset and speech delays, indicating a significant overlap.
Area of Science:
- Child psychology
- Neurodevelopmental disorders
- Clinical audiology
Background:
- Selective mutism (SM) is increasingly recognized as potentially comorbid with autism spectrum disorder (ASD).
- Understanding the relationship between SM and ASD is crucial for accurate diagnosis and intervention.
Purpose of the Study:
- To investigate the prevalence and characteristics of autism spectrum disorder (ASD) in children diagnosed with selective mutism (SM).
Main Methods:
- Retrospective analysis of medical records for 97 children diagnosed with SM at a specialized medical center.
- Examination of demographic data, symptom onset, age at diagnosis, and co-occurring conditions.
Main Results:
- The mean age for SM symptom onset was 4.5 years, and diagnosis was at 8.8 years.
- Selective mutism was more prevalent in girls (2.7:1 ratio).
- A significant 63% of children with SM also had an ASD diagnosis, with no gender difference observed.
Conclusions:
- The study confirms a substantial overlap between autism spectrum disorder and selective mutism.
- Children with comorbid ASD and SM exhibited later symptom onset, delayed diagnosis, and a higher incidence of speech delays and intellectual disabilities.

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.

02:37The Electromagnetic Spectrum
65.5K
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

Electromagnetic waves are categorized according to their wavelengths and frequencies, giving the electromagnetic spectrum. These waves are classified as radio, infrared, ultraviolet, etc. Radio waves refer to electromagnetic radiation with wavelengths ranging from millimeters to kilometers. Radio waves are commonly used for audio communications (i.e., radios) and typically result from an alternating current in the wires of a broadcast antenna. They cover a broad wavelength range and are used...

01:19IR Spectrum
2.3K
When infrared (IR) radiation passes through a molecule, the bonds stretch or bend by absorbing the radiation. This absorption creates the molecule's absorption spectrum, which is the plot of its percentage transmittance versus wavenumber.
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...

A mass spectrum is the graphical representation of the relative abundance of the charged fragments in an analyte plotted against their mass-to-charge ratio (m/z). The plot's x-axis represents the ratio of the mass of the charged fragment to the number of charges it carries. The y axis of the plot represents the relative abundance of each charged species. The relative abundance is calculated from the signal intensity of each charged species recorded at the detector. The most intense signal (the...

01:30UV–Vis Spectrum
2.2K
When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar...
