We aimed to establish age-related reference values for Erythropoietin (EPO) in cerebrospinal fluid (CSF) and to evaluate concentrations in neurological diseases. CSF and serum EPO was measured in controls with tension-type headache (CTTH), in patients with ALS, dementia and depression using ELISA technique. Stability experiments showed CSF EPO to be stable for two and a half months and over two thaw/freeze cycles. A positive correlation of CSF EPO with age was found (P<0.01). We found a CSF/serum EPO concentration ratio of 0.126, pointing towards an intrathecal synthesis of EPO. The ALS group showed significantly lowered CSF EPO compared to age-matched CTTH (P<0.012), whereas the dementia and depression group showed no significant differences compared to CTTH.The establishment of age-related reference values in a large cohort of controls will improve the interpretation of future CSF EPO evaluations in neurological diseases.

The first medical society of Japanese neurologists and psychiatrists was founded in 1902, but psychiatrists gradually dominated in number. New "Japanese Society of Neurology" (JSN) was founded in 1960. The number of members was only 643 in 1960, while it rose up to 8,555 in 2009, including regular, junior, senior and associate members. JSN contributed much to solve the causes and treatment of the medicosocial and iatrogenic diseases such as Minamata disease and SMON (subacute myelopticoneuropathy) at its early period. In undergraduate education at medical school neurology is one of the core subjects in the curriculum, and almost all the 80 medical schools have at least one faculty neurologist. The Board of neurology of JSN was started in 1975, as the third earliest of the Japanese Medical Associations. It takes at least 6 years' clinical training after graduating from the medical school to take the neurology Board examinations. By 2009, 4,000 members passed the Board examinations. In 2002 JSN published evidence-based "Treatment Guidelines 2002" of 6 diseases: Parkinson's disease, stroke, chronic headache, dementia and ALS. As to the international issues, JSN hosted the 12th World Congress of Neurology in 1981, and international activities markedly increased after that. The first informal meeting with JSN and Korean Neurological Association (KNA) was held at the 48th JSN Annual Meeting in Nagoya in May 2007. In May 2008 the KNA-JSN 1st Joint symposium was held at the 49th Annual Meeting of JSN in Yokohama on "International comparison of neurological disorders: focusing on spinocerebellar atrophies (SCA) and epilepsies". In May 2009, KNA-JNS 2 nd Joint Symposium was held at the 50th JSN Annual Meeting in Sendai, inviting a speaker from Taiwan Neurological Society, on the subject "History and Education of Neurology in Japan, Korea and Taiwan". In this symposium, a strategy to make up the Northeast Asian Neurological Association was discussed.

A diagnostic biomarker for ALS would permit early intervention with disease-modifying therapies while a biomarker for disease activity could accelerate the pace of drug discovery by facilitating shorter, and less costly, drug trials to be conducted with a smaller number of patients. Neurofilaments are the most abundant neuronal cytoskeletal protein. We set out to determine whether pNfH was a credible biomarker for ALS. pNfH levels were determined using an ELISA for 150 ALS subjects and 140 controls. We demonstrated a seven-fold elevation in the cerebrospinal fluid (CSF) levels of phosphorylated neurofilament heavy subunit (pNfH) in ALS (median = 2787 pg/ml, n = 150), compared to headache and other benign controls (394 pg/ml, n = 100, p = < 0.05). There was a 10-fold elevation of pNfH compared to ALS mimics (266 pg/ml, n = 20) and other neurodegenerative and inflammatory conditions (279 pg/ml for n = 20) which was also highly significant (p = < 0.05). pNfH achieved a diagnostic sensitivity of 90% and specificity of 87% in distinguishing ALS from all controls. We also detected an inverse correlation between CSF pNfH levels and disease duration (time from symptom onset to death, r(2 = )0.1247, p = 0.001). In conclusion, pNfH represents a promising candidate for inclusion in a panel of diagnostic and prognostic biomarkers.
