The influence is well demonstrated in the antiphospholipid syndrome (APS). This syndrome is characterized by a triad of arterial or venous thrombotic events, recurrent fetal loss and thrombocytopenic purpura. The syndrome exhibits different neurological pathologies such as: chorea, seizures, transverse myelopathy, migraine, cerebral ataxia, hemiballismus and transient global amnesia, which are not fully explained by the procoagulopathic trait of APLA. A study on mice induced with APS demonstrated hyperactive behavior when compared to the control group. The information gathered from these different studies raised the question whether APLA has any part in the etiology of Attention Deficit/Hyperactive Disorder (ADHD) in children.</p> <p>We compared 41 children diagnosed with ADHD to a control of 28 healthy children. Blood drawn
from the two groups was screened using ELISA for the presence of anti-cardiolipin antibodies, antiβ2GP
antibodies, anti-phosphatidyleserine antibodies and anti-ethanolamine antibodies. The results
show no significant difference in the level of antiphospholipid antibodies (APLA) measured between
the children diagnosed with ADHD and the control group.</p>
