BDNF and COMT, but not APOE, alleles are associated with psychiatric symptoms in refractory epilepsy

The objective of this study was to determine whether three common genetic polymorphisms [apolipoprotein (APOE) ε4 (rs42938 and rs7412), brain derived neurotrophic factor (BDNF) Met (rs6265), and catechol-O-methyltransferase (COMT) Val (rs4680)] are associated with increased psychiatric symptomatology in individuals with pharmacoresistant epilepsy.MethodsOne hundred forty-eight adults (Mage = 38 years; 53% female) with refractory epilepsy completed self-report measures of mood, anxiety, and/or personality/psychopathology. Mann–Whitney U, t-tests, and Fisher's exact tests were used to determine if APOE4, BDNF Val66Met, or COMT Val158Met are associated with increased psychiatric symptomatology in people with epilepsy.ResultsAs a group, BDNF Met carriers reported greater symptoms of depression on the Personality Assessment Inventory (PAI) than those without a Met allele (p = 0.004); COMT Val carriers reported greater symptoms on the PAI Schizophrenia (p = 0.007), Antisocial Features (p = 0.04), and Alcohol Problems (p = 0.03) scales than noncarriers. On the individual level, a significantly greater proportion of BDNF Met carriers demonstrated elevated PAI Depression scores compared to those without a Met allele (p = 0.046). There was also a larger proportion of COMT Val carriers with elevated PAI Anxiety scores as compared to those without a Val allele (p = 0.036).SignificanceThis retrospective cross-sectional study provides preliminary...

Conclusion: Some patients with psychiatric syndromes and increased ANA titers may suffer from psychiatric variants of SLE, even if the American College of Rheumatology criteria for SLE are not met. Whether the psychiatric symptoms in our patient represent a prodromal stage with the later manifestation of full-blown SLE or a subtype of SLE with isolated CNS involvement remains unclear. Regardless, early diagnosis and initiation of immunosuppressive treatment are essential steps in preventing further disease progression and organ damage. Intrathecal ANAs with extractable nuclear antigen differentiation may be a more sensitiv...

We present the case of an 80-year-old woman, single with no children, who lived alone, and, up until presentation, was able to perform activities of daily living self-sufficiently. She reported to have the support of friends and neighbors, and she lived in the small community of São Miguel Island, Azores, Portugal. She had completed two years of college before dropping out during her third year, and her last job was as an elder care-worker. She had no personal or family psychiatric antecedents and no history of alcohol or illicit drug addictions. The patient was diagnosed with DM2 two years previously and was treate...

Authors: Danek M, Danek J, Araszkiewicz A Abstract Many animal models in different species have been developed for mental and behavioral disorders. This review presents large animals (dog, ovine, swine, horse) as potential models of this disorders. The article was based on the researches that were published in the peer-reviewed journals. Aliterature research was carried out using the PubMed database. The above issues were discussed in the several problem groups in accordance with the WHO International Statistical Classification of Diseases and Related Health Problems 10thRevision (ICD-10), in particular regarding: ...

Conclusion: This novel technology discriminates and quantifies subtle differences in behavior and neurological impairments in subjects afflicted with neurological injury/disease. KINARM assessments can be incorporated into multi-center trials (e.g., monitoring stroke motor recovery: NCT02928393). Further studies will determine if KINARM Labs can demonstrate a clinical effect with fewer subjects over a shorter trial period. Disclosures/funding: Dr. Stephen Scott is the inventor of KINARM and CSO of BKIN Technologies.   Multiplexed mass spectrometry assay identifies neurodegeneration biomarkers in CSF Presenter: Chelsky...

Marijuana has proved to be a powerful aid in easing chronic pain and helping battle nausea, but results are mixed or largely inconclusive on other health benefits, as well as detriments, according to a massive new scientific review of cannabis studies. The report, released Thursday by the National Academies of Science, Engineering, and Medicine, analyzes an astounding 10,000 scientific studies on the drug. “The Health Effects of Cannabis and Cannabinoids: The Current State of Evidence and Recommendations for Research” concludes that marijuana definitely provides some health benefits, though other claims ab...
