This study examined whether regular swimming in older adults was related to better cognitive functioning and whether there were any global or selective positive effects of this physical activity (PA) on cognition. The cognitive performances of three groups of sixteen volunteer participants (young adults, sedentary older adults, and older adults who regularly practice swimming) were evaluated using a multitask approach. All participants performed a battery of ten tasks: two reaction time tasks assessing information processing speed and eight experimental tasks assessing three executive functions (EFs), (behavioral inhibition, working memory updating, and cognitive flexibility). The results showed that young adults performed significantly better than older adults on all examined cognitive functions. However, in older adults, regular swimming was related to better performance on the three EFs, but not on information processing speed. More precisely, five experimental tasks out of the eight tapping EFs were shown to be sensitive to positive effects from swimming practice. Finally, the demonstrated benefits of swimming on EFs were not necessarily linked to better cardiorespiratory fitness. The present findings illustrate the validity of using a multitask approach in examining the potential benefits of regular PA on cognitive aging.

The Relationship

Nors susirgus išsėtine skleroze (IS) 40–70% žmonių sutrinka kognityvinis funkcionavimas, o depresija taip pat dažnai lydi IS (nustatoma 27–54% sergančiųjų), duomenys apie jų sąryšį gana prieštaringi. Straipsnyje analizuojamas kognityvinio funkcionavimo ir depresiškumo ryšys sergant išsėtine skleroze ir Trumpo daugiakarčio neuropsichologinių testų rinkinio (BRBNT) taikymo galimybės. Tyrime dalyvavo 41 žmogus, sergantis IS, ir 52 sveiki asmenys. Kognityvinėms funkcijoms vertinti buvo išversta ir naudojama BRBNT B versija (Rao and Peyser, 1986). Depresiškumui vertinti buvo taikomas Becko depresijos inventarijus (BDI-II). Gauti rezultatai rodo, jog sergančiųjų IS verbalinis išmokimas yra neigiamai susijęs su depresiškumu: depresiškumas statistiškai reikšmingai koreliuoja su pastovaus ilgalaikio atgaminimo rodikliais ir su ilgalaikiu atgaminimu po tam tikro uždelsimo laikotarpio, tačiau hipotezė, jog egzistuoja ryšys tarp informacijos apdorojimo greičio ir depresiškumo, nepasitvirtino. Klasifikuojant tiriamuosius į sveikus ir sergančius IS, gautas 100% BRBNT jautrumas, taip pat 100% specifiškumas.Pagrindiniai žodžiai: išsėtinė sklerozė, kognityvinis funkcionavimas, depresiškumas. THE RELATIONSHIP BETWEEN COGNITIVE FUNCTION AND DEPRESSION SEVERITY IN MULTIPLE SCLEROSIS PATIENTS: APPLICATION OF THE BRIEF REPEATABLE BATTERY OF NEUROPSYCHOLOGICAL TESTS (BRBNT) IN LITHUANIARamunė Grambaitė, Rūta Sargautytė SummaryMultiple sclerosis (MS) is an inflammatory and neurodegenerative disorder that affects primarily the cerebral white matter, thereby causing both physical and psychological disability. The purpose of this study was to investigate the possible relationship between cognitive function and depression severity in MS patients, as well as sensitivity and specificity characteristics of the BRBNT (The Brief Repeatable Battery of Neuropsychological Tests). We investigated 41 MS patients and 52 healthy people.Forty-one controls were selected from fifty-two healthy subjects and were individually matched with MS subjects for age, gender and education. BRBNT (Rao and Peyser, 1986) was designed for measuring verbal learning, visuospatial learning, sustained attention and concentration, information processing speed and verbal fluency cognitive functions. The B version of the BRBNT was translated and used in our study. Beck Depression Inventory-Second Edition (BDI-II) (Beck, 1996) was used for the evaluation of depression severity.Results of our study confirmed that depression severity was associated with verbal learning: Consistent Long Term Retrieval and the Delayed Recall significantly negatively related to depression severity. The relationship between information processing speed and depression severity was also negative, but not statistically significant. The five individual BRBNT tests separately did not significantly discriminate healthy controls from MS patients; however, when all the five BRBNT tests put together we found 100% sensitivity of and 100% specificity.Our findings lead to the conclusion that neuropsychological testing is important in organizing help strategies for MS patients. BRBNT is a sensitive measure of cognitive function in MS, and may assist with differential diagnosis. Similarly, BRBNT could well be applied to other groups of patients, whose illness results in physical and/or cognitive functional limitations.Keywords: multiple sclerosis, cognitive function, depression severity.

Longitudinal Associations

BackgroundAffective disorders are associated with poorer cognition in older adults; however, whether this association can already be observed in mid-life remains unclear.AimsTo investigate the effects of affective symptoms over a period of 30 years on mid-life cognitive function. First, we explored whether timing (sensitive period) or persistence (accumulation) of affective symptoms predicted cognitive function. Second, we tested how different longitudinal trajectories of affective symptoms were associated with cognitive function.MethodThe study used data from the National Child Development Study. Memory, verbal fluency, information processing speed and accuracy were measured at age 50. Affective symptoms were measured at ages 23, 33, 42 and 50 and used to derive longitudinal trajectories. A structured modelling approach compared a set of nested models in order to test accumulation versus sensitive period hypotheses. Linear regressions and structural equation modelling were used to test for longitudinal associations of affective symptoms with cognitive function.ResultsAccumulation of affective symptoms was found to be the best fit for the data, with persistent affective symptoms being associated with poorer immediate memory (b = −0.07, s.e. = 0.03, P = 0.01), delayed memory (b = −0.13, s.e. = 0.04, P < 0.001) and information processing accuracy (b = 0.18, s.e. = 0.08, P = 0.03), but not with information processing speed (b = 3.15, s.e. = 1.89, P = 0.10). Longitudinal trajectories of repeated affective symptoms were associated with poorer memory, verbal fluency and information processing accuracy.ConclusionsPersistent affective symptoms can affect cognitive function in mid-life. Effective management of affective disorders to prevent recurrence may reduce risk of poor cognitive outcomes and promote healthy cognitive ageing.Declaration of interestNone.

e14018 Background: Chemotherapy improves the survival rate of stage III colon cancer patients. The combination of oxaliplatin, 5-fluorouracil and leucovorin (the FOLFOX4 regimen) has emerged as the standard of care. Cognitive changes and disfunction after cancer chemotherapy are increasingly reported as a disturbing side-effect in cancer survivors. This prospective study evaluates potential alterations in cognitive function in Folfox4-treated patients. Methods: We evaluated 57 consecutive colorectal cancer patients who received adjuvant chemotherapy with FOLFOX4. Patients underwent a complete battery of neuropsychological tests at three different times: before (T0), at the end (T1) and six months after treatment (T2). Changes in neuropsychological test scores at T0, T1 and T2 were compared with a two tail t-test (T1-T0, T2-T1, T2-T0), using the repeated measure ANOVA model. Results: We have analyzed cognitive impairment (Mini Mental State Examination, MMSE), visuo-spatial memory, information processing speed (Trial Making Test-A and Trial Making Test-B), verbal memory (Rey Auditory Verbal Learning Test), emotional distress (Psychological Distress Inventory), anxiety (State and Trait Anxiety Inventory) and depression (Beck Depression Inventory). We found no cognitive impairment in time considered, as we found a median MMSE score of 27,51 ± 1,21 at T0, 27,63 ± 0,65 at T1 and 27,26 ± 1,17 at T2. We noticed some transient variations in tests evaluating verbal memory and in information processing speed performances. The only significative scores modifications were those related to anxiety and depression. Conclusions: We found no significant effect on cognitive function related to chemotherapy, the only little modification is about some emotional performance during chemotherapy. These findings may be explained by the central role of the psychological adaptation process, which occurs during the period from diagnosis to completion of treatment and is characterized by anxiety and adjustment depression. Our results seem to rule out any significant cognitive impairment due to adjuvant Folfox4 chemotherapy in colon cancer patients.

This study aimed to develop a psychometrically valid touch screen tablet-based cognitive test battery to identify early cognitive impairment due to dementia in older adults. The battery includes eight tests with 13 subscores, evaluating visual attention, auditory attention, information processing speed, visual memory, motor control, and visuospatial perception. Among the participants, 43 had been diagnosed with mild cognitive impairment (MCI) and 36 with probable Alzheimer’s disease (AD); 41 had no cognitive impairment. The average time to administer the tablet-based tests was 10 minutes. Significant correlations with the Mini-Mental State Examination were found in 9 out of 13 subscores. Patients with probable AD scored significantly lower than controls in 8 out of 13 subscores, whereas those with MCI scored significantly lower in 4 out of 13 subscores. Confirmatory factor analysis using Promax rotation showed that four factors caused lower subscores in the MCI group compared with the controls: information processing speed, memory, visuospatial perception, and motor control. All four factors significantly discriminated the controls from the MCI and probable AD groups, and in the expected direction. The touch screen tablet-based cognitive test battery is psychometrically valid for evaluating cognition in older adults.

AbstractWe examined cognitive predictors of speech and articulation rate in 50 individuals with multiple sclerosis (MS) and 23 healthy controls. We measured speech and articulation rate from audio-recordings of participants reading aloud and talking extemporaneously on a topic of their choice (i.e., self-generated speech). Articulation rate was calculated for each speech sample by removing lexically irrelevant vocalizations and pauses of >200 ms. Speech rate was similarly calculated including pauses. Concurrently, the Minimal Assessment of Cognitive Function in Multiple Sclerosis (MACFIMS) battery, as well as standardized tests of sentence intelligibility and syllable repetition were administered. Analysis of variance showed that MS patients were slower on three of the four rate measures. Greater variance in rate measures was accounted for by cognitive variables for the MS group than controls. An information processing speed composite, as measured by the Symbol Digit Modalities Test (SDMT) and the Paced Auditory Serial Addition Test (PASAT), was the strongest predictor among cognitive tests. A composite of memory tests related to self-generated speech, above and beyond information processing speed, but not to oral reading. Self-generated speech, in this study, was not found to relate more strongly to cognitive tests than simple reading. Implications for further research are discussed. (JINS, 2012, 18, 1–8)
