Prior to expanded newborn screening, MCADD was an underdiagnosed cause of sudden death in infants. Individuals who have been identified prior to the onset of symptoms have an excellent prognosis. MCADD is most prevalent in individuals of Northern European Caucasian descent, with an incidence of 1:4000 to 1:17,000 depending on the population.
Avoidance of fasting periods, high-fat diets, and dehydration is recommended for those who are affected. A diet consisting of low-fat intake and supplemental calories is common for management of VLCAD deficiency. If a metabolic crisis is not treated, a child with VLCAD can develop: breathing problems, seizures, coma, sometimes leading to death.
In addition to the fetal complications, they can also cause complications for the mother during pregnancy. [4] Examples include: Mitochondrial trifunctional protein deficiency (MTPD) [3] MCADD, LCHADD, and VLCADD [5] Schematic demonstrating mitochondrial fatty acid beta-oxidation and effects of LCHAD deficiency
In the middle of the 20th century the principal treatment for some of the amino acid disorders was restriction of dietary protein and all other care was simply management of complications. In the past twenty years, new medications, enzyme replacement, gene therapy, and organ transplantation have become available and beneficial for many ...
Chromosome 12. SCADD is caused genetically by mutations in the ACADS gene, located on chromosome 12q22-qter. [8] Mutations in the ACADS gene lead to inadequate levels of short-chain acyl-CoA dehydrogenase, which is important for breaking down short-chain fatty acids.
The causes of SIDS and SUDC are not definitively known but there are good chances heart arrhythmias and seizures are the main causes. Although it can happen to any child under the age of 18 (after which the deaths are classified as Sudden arrhythmic death syndrome (SADS)), it is most common in those aged between 1–4 years, where according to ...

The scientific study of the causes of developmental disorders involves many theories. Some of the major differences between these theories involves whether environment disrupts normal development, if abnormalities are pre-determined, or if they are products of human evolutionary history which become disorders in modern environments (see evolutionary psychiatry).
