We reported 9 cases of primary Sjogren syndrome (SS) who were complicated with nervous system involvement. All were women. Age between 24 to 58 years old. Their clinical symptoms of the nervous system varied widely, 7 of them manifested with the involvement of central nervous system, the main features were in case 1 bouts of seizures, case 2 multi-level damage of the brain and spinal cord which was similar to multiple sclerosis, case 3 recurrent hemiplegia caused by cerebral thrombosis then fatal vascular hemorrhage, case 4 sudden hemiplegia, case 5 persistent psychological disturbance, case 6 cranial neuropathy of V and VII, case 9 multi-focal symptoms of ataxia, myelopathy and transient blindness. 5 of the 9, case 3, 6-9 all appeared with the symptoms of peripheral neuropathy, case 7 also complicated with carpal tunnel syndrome. 4 of the 9 cases also complicated with renal tubular acidosis and/or chronic active hepatitis and/or fibrosing alveolitis and/or thrombocytopenic purpura and/or myositis. No differences of the positivity of autoantibodies was observed between those with or without nervous system involvement.

Numerous studies have shown the pathological influence anti-phospholipid antibodies (APLA) have on the physiology of the single neuron as well as the function of the entire human nervous system. 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. 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, anti-beta2GP 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.

The authors report on an unusual case of extensive brain stem lesions as a manifestation of thrombotic thrombocytopenic purpura (TTP). A 28-year-old woman developed rapidly progressive neurologic deficits 5 days after a cesarean delivery. Her condition had been normal after delivery. Initial magnetic resonance imaging (MRI) revealed extensive T2 hyperintense lesions involving the entire brain stem; only part of the pons showed hyperintense abnormalities in a concomitantly taken diffusion-weighted image. The hematologic evaluations and her clinical course revealed the diagnosis of TTP, so plasma exchange and methyl-prednisolone therapy were initiated. After 10 days of treatment, she developed neurologic improvement. A follow-up MRI on the 75th day revealed dramatically reduced brain stem lesions with only residual punctate lesions in the pons. Her remaining neurologic deficits were dysarthria, limb ataxia, and left hemiparesis. As demonstrated in this study, extensive brain stem involvement should be added as a possible neuroimaging feature of TTP.
