High hs-CRP levels after an attempted suicide : A matched case-control study

Publisher Copyright: © 2022 The AuthorsWe found significantly higher levels of hs-CRP in 27 subjects who had recently attempted suicide compared to 27 age- and sex-matched healthy subjects. Moreover, the levels of hs-CRP in suicide attempters were not related to background or psychopathological characteristics, nor to the methods of suicide attempt. Our matched case-control study confirms previous observations of high levels of the inflammation marker hs-CRP in patients who have attempted suicide, irrespective of their underlying type and levels of psychopathology.Peer reviewe

Operationalizing mild cognitive impairment criteria in small vessel disease: The VMCI-Tuscany Study

Introduction Mild cognitive impairment (MCI) prodromic of vascular dementia is expected to have a multidomain profile. Methods In a sample of cerebral small vessel disease (SVD) patients, we assessed MCI subtypes distributions according to different operationalization of Winblad criteria and compared the neuroimaging features of single versus multidomain MCI. We applied three MCI diagnostic scenarios in which the cutoffs for objective impairment and the number of considered neuropsychological tests varied. Results Passing from a liberal to more conservative diagnostic scenarios, of 153 patients, 5% were no longer classified as MCI, amnestic multidomain frequency decreased, and nonamnestic single domain increased. Considering neuroimaging features, severe medial temporal lobe atrophy was more frequent in multidomain compared with single domain. Discussion Operationalizing MCI criteria changes the relative frequency of MCI subtypes. Nonamnestic single domain MCI may be a previously nonrecognized type of MCI associated with SVD

Altered language network lateralization in euthymic bipolar patients: a pilot study

Bipolar patients (BD) in the euthymic phase show almost no symptoms, nevertheless possibility of relapse is still present. We expected to find a psychobiological trace of their vulnerability by analyzing a specific network-the Language Network (LN)-connecting many high-level processes and brain regions measured at rest. According to Crow's hypothesis on the key role of language in the origin of psychoses, we expected an altered asymmetry of the LN in euthymic BDs. Eighteen euthymic BD patients (10 females; age = 54.50 +/- 11.38 years) and 16 healthy controls (HC) (8 females; age = 51.16 +/- 11.44 years) underwent a functional magnetic resonance imaging scan at rest. The LN was extracted through independent component analysis. Then, LN time series was used to compute the fractional amplitude of the low-frequency fluctuation (fALFF) index, which was then correlated with clinical scales. Compared with HC, euthymic patients showed an altered LN with greater activation of Broca's area right homologous and anterior insula together with reduced activation of left middle temporal gyrus. The normalized fALFF analysis on BD patients' LN time series revealed that the Slow-5 fALFF band was positively correlated with residual mania symptoms but negatively associated with depression scores. In line with Crow's hypothesis postulating an altered language hemispheric asymmetry in psychoses, we revealed, in euthymic BD patients, a right shift involving both the temporal and frontal linguistic hubs. The fALFF applied to LN allowed us to highlight a number of significant correlations of this measure with residual mania and depression psychiatric symptoms

The burden of microstructural damage modulates cortical activation in elderly subjects with MCI and leuko-araiosis. A DTI and fMRI study

The term leuko-araiosis (LA) describes a common chronic affection of the cerebral white matter (WM) in the elderly due to small vessel disease with variable clinical correlates. To explore whether severity of LA entails some adaptive reorganization in the cerebral cortex we evaluated with functional MRI (fMRI) the cortical activation pattern during a simple motor task in 60 subjects with mild cognitive impairment and moderate or severe (moderate-to-severe LA group, n = 46) and mild (mild LA group, n = 14) LA extension on visual rating. The microstructural damage associated with LA was measured on diffusion tensor data by computation of the mean diffusivity (MD) of the cerebral WM and by applying tract based spatial statistics (TBSS). Subjects were examined with fMRI during continuous tapping of the right dominant hand with task performance measurement. Moderate-to-severe LA group showed hyperactivation of left primary sensorimotor cortex (SM1) and right cerebellum. Regression analyses using the individual median of WM MD as explanatory variable revealed a posterior shift of activation within the left SM1 and hyperactivation of the left SMA and paracentral lobule and of the bilateral cerebellar crus. These data indicate that brain activation is modulated by increasing severity of LA with a local remapping within the SM1 and increased activity in ipsilateral nonprimary sensorimotor cortex and bilateral cerebellum. These potentially adaptive changes as well lack of contralateral cerebral hemisphere hyperactivation are in line with sparing of the U fibers and brainstem and cerebellar WM tracts and the emerging microstructual damage of the corpus callosum revealed by TBSS with increasing severity of LA. © 2012 Wiley Periodicals, Inc

Development and psychometric properties of a neuropsychological battery for mild cognitive impairment with small vessel disease: The VMCI-tuscany study

BACKGROUND AND OBJECTIVE: Vascular cognitive impairment may have a selective neuropsychological profile. We developed a battery for assessing mild cognitive impairment (MCI) in patients with small vessel disease (SVD), its applicability, and psychometric properties. METHODS: Among those proposed by the 2006 NINDS-CSN Consensus Conference, we selected tests for which norms based on healthy Italians and equivalent scores methodology were available. Confirmatory factor analysis was applied to ascertain the fit of the theoretically assumed dimensions to empirical data and to derive each cognitive dimension compound measures. RESULTS: The entire battery was applied to 146 out of a cohort of 201 patients with MCI and SVD. Most tests showed good applicability. Fifty-five patients, who were older and cognitively more impaired, proved unable to complete the Trail Making Test part B, the Rey-Osterrieth Complex Figure, and the Stroop test, and were excluded from the analysis. Among the remaining patients, Mini-Mental State Examination proved largely normal, while Rey-Osterrieth Complex Figure, Symbol digit modalities test, and Trail Making Test part B were most frequently abnormal. Confirmatory factor analysis showed a good fit of the 4-factor theoretical model to empirical data. Praxis domain resulted in the highest percentage of abnormal performance (65%), followed by Memory and Attention/EF domains (19% and 15%), and Language (8%). CONCLUSIONS: Our battery proved to be comprehensive, robust, and applicable. Attention-executive dysfunction and impaired memory and visuo-constructional abilities, were the prominent features. The assessment of the Consensus Conference, that included Trial Making Test, looks poorly applicable to older and cognitively impaired patients
