A patient with Korsakoff syndrome of psychiatric and alcoholic etiology presenting as DSM-5 mild neurocognitive disorder

Background: Wernicke's encephalopathy (WE) and Korsakoff syndrome (KS) are underdiagnosed. The DSM-5 has raised the diagnostic threshold by including KS in the major neurocognitive disorders, which requires that the patient needs help in everyday activities. Methods: We report clinical, neuropsychological, and radiological findings from a patient who developed Wernicke-Korsakoff syndrome as a result of alcohol use and weight loss due to major depression. We assess the diagnosis in the context of the scientific literature on KS and according to the DSM-IV and the DSM-5. Results: The patient developed ataxia during a period of weight loss, thus fulfilling current diagnostic criteria of WE. WE was not diagnosed, but the patient partially improved after parenteral thiamine treatment. However, memory problems became evident, and KS was considered. In neuropsychological examination, the Logical Memory test and the Word List test were abnormal, but the Verbal Pair Associates test was normal (Wechsler Memory Scale-III). There were intrusions in the memory testing. The Wisconsin Card Sorting Test was broadly impaired, but the other test of executive functions (difference between Trail Making B and Trail Making A tests) was normal. There was atrophy of the mammillary bodies, the thalamus, the cerebellum, and in the basal ganglia but not in the frontal lobes. Diffusion tensor imaging showed damage in several tracts, including the uncinate fasciculi, the cinguli, the fornix, and the corona radiata. The patient remained independent in everyday activities. The patient can be diagnosed with KS according to the DSM-IV. According to the DSM-5, the patient has major neurocognitive disorders. Conclusions: Extensive memory testing is essential in the assessment of KS. Patients with a history of WE and typical clinical, neuropsychological, and radiological KS findings may be independent in everyday activities. Strict use of the DSM-5 may worsen the problem of Wernicke-Korsakoff syndrome underdiagnosis by excluding clear KS cases that do not have very severe functional impairment.Peer reviewe

Non-alcoholic Korsakoff syndrome in psychiatric patients with a history of undiagnosed Wernicke's encephalopathy

Wernicke's encephalopathy is often undiagnosed, particularly in non-alcoholics. There are very few reports of non-alcoholic patients diagnosed with Korsakoff syndrome in the absence of a prior diagnosis of Wernicke's encephalopathy and no studies of diffusion tensor imaging in non-alcoholic Korsakoff syndrome. We report on three non-alcoholic psychiatric patients (all women) with long-term non-progressive memory impairment that developed after malnutrition accompanied by at least one of the three Wemicke's encephalopathy manifestations: ocular abnormalities, ataxia or unsteadiness, and an altered mental state or mild memory impairment. In neuropsychological examination, all patients had memory impairment, including intrusions. One patient had mild cerebellar vermis atrophy in MRI taken after the second episode of Wemicke's encephalopathy. The same patient had mild hypometabolism in the lateral cortex of the temporal lobes. Another patient had mild symmetrical atrophy and hypometabolism of the superior frontal lobes. Two patients were examined with diffusion tensor imaging. Reduced fractional anisotropy values were found in the corona radiata in two patients, and the uncinate fasciculus and the inferior longitudinal fasciculus in one patient. Our results suggest that non-alcoholic Korsakoff syndrome is underdiagnosed. Psychiatric patients with long-term memory impairment may have Korsakoff syndrome and, therefore, they should be evaluated for a history of previously undiagnosed Wernicke's encephalopathy.

Recurrent depression in childhood and adolescence and low childhood socioeconomic status predict low cardiorespiratory fitness in early adulthood

Background: Cardiorespiratory fitness (CRF) strongly influences health, but very little is known about the childhood determinants of adult CRF. Our longitudinal study investigated whether childhood psychopathology and socioeconomic status (SES) were related to adult CRF in 1647 Finnish male military conscripts. Methods: Childhood psychopathology was assessed at the age of eight using the Rutter and Children's Depression Inventory questionnaires. Parental education and family structure were used to assess childhood SES. In late adolescence, depressive symptoms were assessed with the Beck Depression Inventory and smoking with a questionnaire. CRF in early adulthood was examined with the Cooper's 12-minute run test. Results: General linear models showed that low parental education (p = 0.001), depressive symptoms in childhood (p = 0.035) and late adolescence, smoking, underweight, and overweight/obesity (all p <0.001) independently predicted lower CRF. The interaction between depressive symptoms in childhood and adolescence was significant (p = 0.003). In adolescents with depressive symptoms, childhood depressive symptoms (p =0.001) and overweight/obesity (p <0.001) predicted lower CRF. In adolescents without depressive symptoms, conduct problems in childhood predicted lower CRF in the initial models, but the effect disappeared after taking into account smoking and body mass index. Mediational analysis confirmed these results. Limitations: We lacked data on physical activity and only studied males at three time-points. Conclusions: Recurrent depression in childhood and adolescence and low SES in childhood predict lower adult CRF. Conduct problems in childhood predict lower CRF, but the effect is mediated by overweight/obesity and smoking. Psychiatric treatment for children and adolescents should promote physical activity, particularly for children with low SES.Peer reviewe

Mistä unettomuushäiriössä on kyse?

Vertaisarvioitu.Unettomuus parantaa vireystasoa stressitilanteessa, mutta unettomuushäiriö kehittyy, kun unettomuus itsessään alkaa aiheuttaa huolta ja stressiä. Pitkäkestoisessa unettomuushäiriössä oireet kestävät vähintään kolme kuukautta. Unettomuushäiriön syntymekanismi sisältää altistavia, laukaisevia ja ylläpitäviä tekijöitä. Vakiintuneet kielteiset olettamukset ja tulkinnat omasta unesta, haitalliset mielleyhtymät sekä epätarkoituksenmukaiset selviytymisyritykset ylläpitävät unettomuutta. Samalla uni-valvejärjestelmän fysiologisessa säätelyssä tapahtuu muutoksia. Puolet pitkäkestoisesta unettomuushäiriöstä kärsivistä potilaista nukkuu normaalin pituisia unia. Näillä potilailla kärsimystä tuottaa unen kokemisen häiriö ja huonolaatuinen uni. Puolet pitkäkestoisesta unettomuushäiriöstä kärsivistä potilaista puolestaan nukkuu objektiivisestikin lyhentyneitä unia. Unettomuushäiriö altistaa somaattisille ja psyykkisille sairauksille. Sen hoito kohdentuu haitallisiin ajatus- ja käyttäytymismalleihin sekä unen ja valveen säätelyjärjestelmään.Peer reviewe

Obesity, Underweight, and Smoking Are Associated with Worse Cardiorespiratory Fitness in Finnish Healthy Young Men: A Population-Based Study

BackgroundObesity and smoking are strongly associated with worse cardiorespiratory fitness (CRF). Most previous studies that have examined the association of body composition with CRF have neither assessed non-linearity nor separately examined the effects of underweight. Thus, very little is known on how underweight affects CRF. Possible joint effects of obesity and smoking on CRF have not been adequately explored.AimsWe examined the association between body mass index (BMI) and smoking with CRF in 1,629 Finnish army conscripts. We focused on non-linear effects of BMI in order to assess the importance of underweight. We also examined whether the cooccurrence of obesity and smoking potentiates their deleterious effects on CRF.MethodsWe used the Cooper’s 12-minute run test (12MR) to measure CRF. The 12MR score was analyzed as continuous (linear, polynomial, and restricted cubic spline regression) and categorical. In categorical analyses, we used binary logistic regression with the 12MR score in two groups (low = lowest quintile vs. intermediate/high = quintiles 2–5) and multinomial logistic regression with the 12MR score in three groups (low = lowest quintile, intermediate = quintiles 2 and 3, and high = quintiles 4 and 5).ResultsNon-linearity in the spline model was statistically significant (p &lt; 0.001). In addition, the non-linear models had a clearly better fit than the linear one in terms of Akaike Information Criterion and R-squared values. There was a statistically significant interaction between smoking and BMI (p &lt; 0.01). In the categorical analysis, overweight/obese regular smokers were at a particularly high risk of not achieving high CRF.ConclusionIn healthy young men, not only overweight/obesity but also underweight may be associated with worse CRF. This provides a potential mechanism for the previously reported association between underweight and increased mortality. The cooccurrence of overweight/obesity and regular smoking may have a deleterious effect on CRF
