Neuropsychiatric Manifestations of Antiphospholipid Syndrome—A Narrative Review

Antiphospholipid syndrome (APS) is a common autoimmune pro-thrombotic condition characterised by thrombosis and pregnancy morbidity. There are a broad range of neuropsychiatric manifestations associated with APS, from focal symptoms to more global dysfunction. Patients commonly present with transient ischaemic attacks and ischaemic strokes, with identifiable lesions on brain imaging. However, the underlying pathogenesis remains uncertain in other manifestations, such as cognitive dysfunction, seizures, headache and chorea. The aim is to provide a comprehensive review of the various neuropsychiatric manifestations associated with APS. A detailed literature search was applied to PubMed, including citations from 1983 to December 2021.

Transient global amnesia following deliberate self-harm by hanging: Case report and review

A 25-year-old female was hospitalized subsequent to an attempt to hang herself. She was unconscious for a few minutes but responded to initial resuscitative measures. Relevant investigations, including X-ray neck, computed tomography scan brain, and electroencephalogram were normal. Physical examination was consistent with attempted hanging. On mental status examination, speech was relevant. Mood was euthymic. Attention was arousable, but concentration was impaired. Orientation to time and recent memory were impaired. Remote memory, insight, and judgment were unimpaired. Serial Mental Status Examination (MSE) revealed improvement in concentration and orientation. Due to sudden onset memory loss of <24 h in duration without other signs of cognitive impairment or concomitant focal neurological symptoms, she was diagnosed as a case of transient global amnesia. The pathophysiology of the condition is briefly reviewed.

Subclinical carotid atherosclerosis in elderly patients with primary Sjögren syndrome: a duplex Doppler sonographic study

A growing body of evidence presents a link between chronic inflammatory rheumatic diseases and atherosclerosis. To evaluate subclinical carotid atherosclerosis in an elderly group of patients with primary Sjögren syndrome compared with a control group matched for age, sex, ethnicity and cardiovascular risk factors, we enrolled 18 patients with Primary Sjögren Syndrome (mean age 65 ± 5.93 SD) and 18 mild Ostheoarthritic patients (mean age 66 ± 5.94 SD) from the outpatient department of Rheumatology, University “Campus Bio-Medico, Rome, Italy, matched for age, sex, ethnicity and cardiovascular risk factors. A duplex Doppler sonographic study of carotids was performed in order to evaluate intima-media thickness (IMT), stiffness and haemodynamic parameters [resistivity and pulsatility indices (RI and PI, respectively)]. No significant difference was found between primary Sjögren syndrome and control patients in IMT, stiffness and haemodynamic parameters. The lack of significant difference in subclinical atherosclerosis between elderly primary Sjögren syndrome and control matched patients, indicates that traditional cardiovascular risk factors, immunologic alterations and chronic inflammation do not influence the progression of vascular damage in the carotid circulation of patients with median disease duration of 6.5 years.

Systemic Lupus Erythematosus Patients with and without Neuropsychiatric Manifestations: A Neck and Transcranial Duplex Sonography Study

Neuropsychiatric manifestations are not rarely associated with systemic lupus erythematosus (SLE). Magnetic resonance angiography and positron emission tomography can provide excellent images of cerebral perfusion and metabolism whereas information is still lacking on a possible diagnostic role of ultrasound. In this study we aim to assess whether duplex sonography of neck and intracranial vessels may be useful in distinguishing patients with and without neuropsychiatric SLE (NPSLE). Neck and transcranial duplex sonography was performed by a single operator on 33 women affected by SLE (mean age ± SD: 47.69±8.17 years) and on 15 healthy control subjects. Nineteen patients presented NPSLE. Pulsatility and resistivity indices (PI and RI) were automatically calculated by the ultrasound instrument in internal carotid (ICA) and middle cerebral artery (MCA), on both sides, according to standard methods. No significant haemodynamic differences were found in mean and median PI and RI values of ICA and MCA comparing SLE with NPSLE patients and with healthy control subjects. No correlation was found between MCA and ICA parameters in the same group of patients. Duplex sonography of cerebral vessels is unable to distinguish SLE and NPSLE patients. Heterogeneity of causes in the pathogenesis of NPSLE and the different vascular adaptation of cerebral macrocirculation as opposed to cerebral microcirculation may represent possible reasons that explain the inability of ultrasound to differentiate SLE patients from NPSLE patients.
