A Systematic Review and Meta-Analysis of Cognitive Effects of rTMS in Caucasian Patients with Mild Cognitive Impairment.

In recent years, repetitive transcranial magnetic stimulation (rTMS) has received much attention as a non-invasive, effective treatment modality for mild cognitive impairment (MCI). Although several meta-analyses have reported that rTMS can improve cognitive abilities, improvements in individual memory domains (speech, language, concentration, and memory) are poorly understood. In addition, stimulation parameters may be flawed in studies of global populations because of ethnic differences between Caucasians and Asians. This meta-analysis aimed to systematically characterize the efficacy of different combinations of rTMS parameters on different cognitive domains in Caucasian patients with MCI. We conducted a systematic literature search in Medline PubMed, Pubpsych, and Embase on the use of rTMS in MCI patients through November 2022. Randomized, double-blind, and sham-controlled trials (RCTs) from the Caucasian patient population were included. The studies reported outcome measures for different domains of cognition, such as language, concentration, or memory. Possible effects of covariates were examined using meta-regressions. The search yielded five publications. The analyses found that rTMS improved cognitive functions, memory, concentration, and language in patients with MCI and treatment with rTMS compared with the sham stimulation group. The statistical analysis results of the studies showed that rTMS could improve various cognitive functions, such as memory and concentration, in Caucasian MCI patients. A particular effect was found at a frequency of 10 Hz and stimulation of the LDLPFC. However, further studies are needed to validate these findings and explore more effective stimulation protocols and targets.

The Newly Normed SKT Reveals Differences in Neuropsychological Profiles of Patients with MCI, Mild Dementia and Depression.

The SKT (Syndrom-Kurztest) is a short cognitive performance test assessing deficits of memory and attention in the sense of speed of information processing. The new standardization of the SKT (2015) aimed at improving its sensitivity for early cognitive decline due to dementia in subjects aged 60 or older. The goal of this article is to demonstrate how the neuropsychological test profile of the SKT can be used to provide valuable information for a differential diagnosis between MCI (mild cognitive impairment), dementia and depression. n = 549 patients attending a memory clinic (Nuremberg, Germany) were diagnosed according to ICD-10 and tested with the SKT. The SKT consists of nine subtests, three for the assessment of memory and six for measuring attention in the sense of speed of information processing. The result of the SKT test procedure is a total score, which indicates the severity of overall cognitive impairment. Besides the summary score, two subscores for memory and attention can be interpreted. Using the level of depression as a covariate, statistical comparisons of SKT test profiles between the three patient groups revealed that depressed patients showed more pronounced deficits than MCI patients in all six attention subtests. On the other hand, MCI patients displayed significantly greater mnestic impairment than the depressed group, which was indicated by significant differences in the memory subscore. MCI and dementia patients showed similar deficit patterns dominated by impairment of memory (delayed recall) with MCI patients demonstrating less overall impairment. In sum, the SKT neuropsychological test profiles provided indicators for a differential diagnosis between MCI and beginning dementia vs. depression.

Prevalence of psychiatric diagnoses in asylum seekers with follow-up.

BACKGROUND: In the study, the frequency and nature of asylum seekers' psychiatric diagnoses in a German admission center were examined. Additional aims were to identify changes in those diagnoses over time and to investigate health care utilization of mentally ill asylum seekers in the community. METHODS: The sample for the study "Psychiatric Examination of Asylum Seekers" in Bavaria consisted of a total of 283 asylum seekers and included 2 subsamples: help-seeking individuals and a randomly selected group. 34 of all asylum seekers were part of an extensive psychiatric follow-up examination (t2) about six months after the first examination (t1). Here, we used psychometric tools and a psychiatric interview by a medical doctor and a psychologist with the help of translators. RESULTS: 79% of help-seekers and 45% of the random group received at least one psychiatric diagnosis at t1. The most frequent diagnoses were trauma- and stress-related disorders, affective disorders, and insomnia. Men and Muslims were underrepresented in the help-seeking group. In the follow-up subsample, the rate of psychiatric diagnoses went down from 74% at t1 to 38% at t2. In contrast, the number of PTSD cases increased from 4 at t1 to 7 at t2. The severity of PTSD symptoms such as hyperarousal and avoidance also increased. Of the 13 persons in the follow-up-sample diagnosed with depression at t1, only 2 still fit the criteria of the disease at t2. Only 5 subjects had received some sort of psychotherapy or counseling. CONCLUSION: The prevalence of mental illness in asylum seekers reported here corresponds to the usual range in the literature. It is significantly higher than in European civil society, especially regarding PTSD. At t2, the diagnoses of PTDS had increased within several months without evident additional traumatic events. Asylum seekers' psychiatric diagnoses soon after arrival should be recorded carefully and examination should be repeated after six months. The psychiatric and psychotherapeutic treatment of asylum seekers is still insufficient. Psychoeducative steps should be taken to relieve the stigma on mental illness, especially among males and Muslims.

Sustainable effects on suicidality were found for the Nuremberg alliance against depression.

During an intense four-level community-based intervention program conducted in Nuremberg (490,000 inhabitants) in 2001 and 2002 [Nuremberg Alliance Against Depression (NAD)], the number of suicidal acts (main outcome completed + attempted suicides) had dropped significantly (-21.7%), a significant effect compared with the baseline year and the control region (Wuerzburg, about 290,000 inhabitants). To assess the sustainability of the intervention effects the number of suicidal acts was assessed in the follow-up year (2003), after the termination of the 2-year intervention. Also, in the follow-up year (2003), the reduction in suicidal acts compared with the baseline year in Nuremberg (2000 vs. 2003: -32.4%) was significantly larger than that in the control region (P = 0.0065). The reduction was even numerically larger than that of the intervention years (2001, 2002). Thus, 1 year after the end of the main intervention, preventive effects on suicidality of the NAD remain at least stable. The four-level intervention concept appears to be cost-effective and is presently implemented in many European regions.

Seasonality of suicide attempts: association with gender.

Some studies suggest seasonality of suicide attempts in females, but not in males. The reasons for this gender difference remain unclear. Only few studies addressed the question whether gender differences in seasonality of suicide attempts reflect gender differences in the choice of method for suicide attempts, with inconsistent results. So, this study aimed to analyze the association of gender with seasonality in suicide attempts by persons living in two Northern Bavarian regions [city of Nuremberg (480,000 inhabitants) and region of Wuerzburg (270,000 inhabitants)] between 2000 and 2004. We addressed this question by focussing on the frequency of suicide attempts in relation to the seasons. The sample consisted of 2,269 suicide attempters (882 males and 1,387 females). The overall seasonality was assessed using the chi(2) test for multinomials. Moreover, the ratio of observed to expected number of suicide attempts (OER) with 95% confidence intervals within each season was calculated. As a result, overall distribution of suicide attempts differed significantly between seasons for women (chi(2) = 9.19, df = 3, P = 0.03), but not for men. Female suicide attempts showed a trough in the spring (decline compared to the expected value by 10%; OER = 0.9, 95% CI = 0.8-1.0). This trough was restricted to female low-risk suicide attempts (decline by 13%; OER = 0.87, 95% CI = 0.77-0.98). No seasonality was found for men. Seasonality of high-risk methods was more pronounced than that of low-risk methods; however, no significant gender differences were found concerning this aspect. The overall distribution of the sub-types of suicidal acts (parasuicidal gestures, suicidal pauses, suicide attempts in the strict sense) showed seasonality neither for males nor for females. Whereas seasonality was absent in male suicide attempters, the frequency of low-risk suicide attempts in females was 13.1% lower than expected in the spring.
