Sudden infant death syndrome (SIDS), sometimes known as cot death or crib death, is the sudden unexplained death of a child of less than one year of age. Diagnosis requires that the death remain unexplained even after a thorough autopsy and detailed death scene investigation. [ 2 ]
Several studies have reported an overlap, confusion or comorbidity with Asperger syndrome (which has been combined with autism spectrum disorder and no longer appears as a diagnostic label in the DSM-5). [82] [83] [84] Asperger syndrome was at one time called "schizoid disorder of childhood".
There has not been enough research to identify risk factors, common characteristics, or prevention strategies for SUDC. SUDC is similar in concept to sudden infant death syndrome (SIDS). Like SIDS, SUDC is a diagnosis of exclusion, the concrete symptom of both being death. However, SIDS is a diagnosis specifically for infants under the age of ...
The results indicated that infants with particular levels of those metabolites in their blood had a higher risk of SIDS — up to 14 times the odds compared to infants with the lowest risk.
A 2003 review of epidemiological studies of children found autism rates ranging from 0.03 to 4.84 per 1,000, with the ratio of autism to Asperger syndrome ranging from 1.5:1 to 16:1; [142] combining the geometric mean ratio of 5:1 with a conservative prevalence estimate for autism of 1.3 per 1,000 suggests indirectly that the prevalence of AS ...
There are no known biomarkers for autism spectrum conditions that allow for a conclusive diagnosis. [ 2 ] In most cases, diagnostic criteria codified in the World Health Organization 's International Classification of Diseases (ICD) or the American Psychiatric Association 's Diagnostic and Statistical Manual of Mental Disorders (DSM) are used.
As of 2013, it is no longer a diagnosis on its own. Instead, patients are diagnosed with Autism Spectrum Disorder, which encompasses Asperger syndrome. Many people still use Asperger's as a term when referring to "high-functioning" individuals with autism, but it is not an official diagnosis.
Most parents report that the onset of autism features appear within the first or second year of life. [11] [12] This course of development is fairly gradual, in that parents typically report concerns in development over the first two years of life and diagnosis can be made around 3–4 years of age. [9]
