Several prenatal and perinatal complications have been reported as possible risk factors for autism. [200] These risk factors include maternal gestational diabetes, maternal and paternal age over 30, [201] [202] [203] bleeding during pregnancy after the first trimester, use of certain prescription medication (e.g. valproate) during pregnancy ...
Diabetes in the mother during pregnancy is a significant risk factor for autism; a 2009 meta-analysis found that gestational diabetes was associated with a twofold increased risk. A 2014 review also found that maternal diabetes was significantly associated with an increased risk of autism. [ 56 ]
The risk of developing autism is increased in the presence of various prenatal factors, including advanced paternal age and diabetes in the mother during pregnancy. [8] In rare cases, autism is strongly associated with agents that cause birth defects. [9] It has been shown to be related to genetic disorders [10] and with epilepsy. [11]
Some research suggests that a particularly intense immune reaction during gestation might increase the risk of neurodevelopmental disorders like autism.
A few genetic polymorphisms such as folate hydrolase 1 and hydroxymethyltransferase 1 along with hyperhomocysteinemia were used as risk factors to develop an artificial neural network (ANN). Studies showed that this model was around 63.8% accurate in predicting ASD risk, implying a moderate association between genetic polymorphisms of the ...
With PTS, these symptoms typically are worse after walking or standing for long periods of time and improve with resting or elevating the leg. [1] PTS lowers a person's quality of life after DVT, specifically with regards to physical and psychological symptoms and limitations in daily activities. [2] [3] [4]
Many of the risk factors that are associated with SVT are also associated with other thrombotic conditions (e.g. DVT). These risk factors include age, cancer, history of thromboembolism, pregnancy, use of oral contraceptive medications (containing estrogen), [4] hormone replacement therapy, recent surgery, and certain autoimmune diseases ...
Risk factors for self-harm and suicidality include circumstances that could affect anyone, such as mental health problems (e.g., anxiety disorder) and social problems (e.g., unemployment and social isolation), plus factors that affect only autistic people, such as actively trying to behave like a neurotypical person, which is called masking.
