- Anorexia nervosa (AN) is a severe psychiatric disorder with high mortality and, to a large extent, unknown pathophysiology. Structural brain differences, such as global or focal reductions in grey or white matter volumes, as well as enlargement of the sulci and the ventricles, have repeatedly been observed in individuals with AN. However, many of the documented aberrances normalize with weight recovery, even though some studies show enduring changes. To further explore whether AN is associated with neuronal damage, we analysed the levels of neurofilament light chain (NfL), a marker reflecting ongoing neuronal injury, in plasma samples from females with AN, females recovered from AN (AN-REC) and normal-weight age-matched female controls (CTRLS). We detected significantly increased plasma levels of NfL in AN vs CTRLS (median(AN) = 15.6 pg/ml, IQR(AN) = 12.1-21.3, median(CTRL) = 9.3 pg/ml, IQR(CTRL) = 6.4-12.9, and p < 0.0001), AN vs AN-REC (median(AN-REC) = 11.1 pg/ml, IQR(AN-REC) = 8.6-15.5, and p < 0.0001), and AN-REC vs CTRLS (p = 0.004). The plasma levels of NfL are negatively associated with BMI overall samples (beta (+/- se) = -0.62 +/- 0.087 and p = 6.9. 10(-12)). This indicates that AN is associated with neuronal damage that partially normalizes with weight recovery. Further studies are needed to determine which brain areas are affected, and potential long-term sequelae.

- Background and purpose Hereditary diffuse leukoencephalopathy with spheroids (HDLS) is a devastating, hereditary white matter (WM) disorder with heterogeneous neuropsychiatric features. Colony stimulating factor 1 receptor (CSF1R) mutations were looked for in primary progressive multiple sclerosis (PPMS) patients and the clinical features of a family with a novel CSF1R mutation are reported. Methods CSF1R exons 12−22 in a cohort of 220 PPMS patients from the Swedish and Norwegian national multiple sclerosis registries were sequenced. Results One patient had a novel mutation, c.2562T>A; p.Asn854Lys, in the CSF1R gene. Her symptoms started at the age of 29 years with insidious onset of pyramidal weakness in the left leg. The cerebrospinal fluid examination showed four intrathecal immunoglobulin G bands. A magnetic resonance imaging scan performed 4 years after symptom onset demonstrated patchy deep WM lesions. She was diagnosed as having PPMS and treated with intramuscular interferon beta 1a. Due to slow disease progression, the development of memory decline and cerebellar signs, she was given subcutaneous interferon beta 1a without any benefit. The updated pedigree indicated that five siblings also had the CSF1R gene mutation; one was diagnosed with PPMS. Six more distant relatives also had a neurological disorder; four were clinically diagnosed with PPMS. Conclusions Our study indicates that a chronic course of HDLS may mimic PPMS. Genetic testing for CSF1R gene mutations in PPMS cases with a positive family history of neurological disorders may establish the diagnosis of HDLS.

- Multiple sclerosis (MS) is associated with inflammatory lesions in the brain and spinal cord. The detection of such inflammatory lesions using magnetic resonance imaging (MRI) is important in the consideration of the diagnosis and differential diagnoses of MS, as well as in the monitoring of disease activity and predicting treatment efficacy. Although there is strong evidence supporting the use of MRI for both the diagnosis and monitoring of disease activity, there is a lack of evidence regarding which MRI protocols to use, the frequency of examinations, and in what clinical situations to consider MRI examination. A national workshop to discuss these issues was held in Stockholm, Sweden, in August 2015, which resulted in a Swedish consensus statement regarding the use of MRI in the care of individuals with MS. The aim of this consensus statement is to provide practical advice for the use of MRI in this setting. The recommendations are based on a review of relevant literature and the clinical experience of workshop attendees. It is our hope that these recommendations will benefit individuals with MS and guide healthcare professionals responsible for their care.
