Adjunctive Magnetic Seizure Therapy for Schizophrenia: A Systematic Review

Objective: The efficacy and safety of adjunctive magnetic seizure therapy (MST) for patients with schizophrenia are unclear. This systematic review was conducted to examine the efficacy and safety of adjunctive MST for schizophrenia.Methods: Chinese (WanFang and Chinese Journal Net) and English (PubMed, EMBASE, PsycINFO, and the Cochrane Library) databases were systematically searched.Results: Two open-label self-controlled studies (n = 16) were included and analyzed in this review. In these studies, the Positive and Negative Syndrome Scale (PANSS) total scores and Brief Psychiatric Rating Scale (BPRS) total scores significantly decreased from baseline to post-MST (all Ps < 0.05), without serious adverse neurocognitive effects. Mixed findings on the neurocognitive effects of adjunctive MST for schizophrenia were reported in the two studies. A discontinuation rate of treatment of up to 50% (4/8) was reported in both studies. The rate of adverse drug reactions (ADRs) was evaluated in only one study, where the most common ADRs were found to be dizziness (25%, 2/8) and subjective memory loss (12.5%, 1/8).Conclusion: There is inconsistent evidence for MST-related adverse neurocognitive effects and preliminary evidence for the alleviation of psychotic symptoms in schizophrenia.

Dementia-Free Older Adults with Subjective Cognitive Impairment Show Lower Mood and No Deficits of Spontaneous Memory Retrieval

The aim of the present study was to investigate whether spontaneous retrieval deficits could be found in individuals with Subjective Cognitive Impairment (SCI). The sample consisted of 52 participants over 65 years of age (mean age = 76.00; SD = 7.48) with 11 males. We asked 26 individuals with SCI and 26 individuals without SCI to perform a prospective memory (PM) task that had previously demonstrated spontaneous retrieval deficits in individuals with Mild Cognitive Impairment. The results did not demonstrate the expected differences in a PM task based on spontaneous retrieval [ t(50) = −.05; p = .964, d = .01]. However, participants’ mood did predict their subjective memory complaints ( β = −.51; p < .001) and their subjective assessment of their future memory performance ( r = −.38; p < .01). The findings are in line with numerous studies which have shown that SCI is more related to mood disturbance than to objective cognitive functioning.

Lifestyle Variables Such as Daily Internet Use, as Promising Protective Factors against Cognitive Impairment in Patients with Subjective Memory Complaints. Preliminary Results

Subjective memory complaints (SMCs) may be important markers in the prediction of cognitive deterioration. The aim of this study was to find associations between individual lifestyle factors, which may contribute to cognitive impairment (CI) in people with SMCs and to conduct a literature review on the relationship between internet use and CI in subjects over 50 years old, as a related factor. This was a case-controlled study that included 497 subjects aged over 50 years with SMCs who were recruited from 19 community pharmacies. Three screening tests were used to detect possible CIs, and individuals with at least one test result compatible with a CI were referred to primary care for evaluation. Having self-referred SMC increased the odds of obtaining scores compatible with CI and this factor was significantly related to having feelings of depression (OR = 2.24, 95% CI [1.34, 3.90]), taking anxiolytics or antidepressants (OR = 1.93, 95% CI [1.23, 3.05]), and being female (OR = 1.83, 95% CI [1.15, 2.88]). Thirty percent of our sample obtained scores compatible with CI. Age over 70 years increased the odds of obtaining scores compatible with CI. A high-level education, reading, and daily internet use were factors associated with a reduced risk of positive scores compatible with CI (37–91%, 7–18%, and 67–86%, respectively), while one extra hour television per day increased the risk by 8–30%. Among others, modifiable lifestyle factors such as reading, and daily internet usage may slow down cognitive decline in patients over 50 with SMCs. Four longitudinal studies and one quasi-experimental study found internet use to be beneficial against CI in patients over 50 years of age.

Hidden Objective Memory Deficits Behind Subjective Memory Complaints in Patients With Temporal Lobe Epilepsy

Objective:To test the hypothesis that temporal lobe epilepsy (TLE) patients with subjective initial memory complaints (not confirmed by an objective standard assessment) and various phenotypes also show objective very long-term memory deficit with accelerated long-term forgetting. We tested TLE patients with two surprise memory tests after three weeks: the standard Free and Cued Selective Reminding Test (FCSRT), and Epireal, a new test specifically designed to capture more ecological aspects of autobiographical memory.Methods:47 TLE patients (12 hippocampal sclerosis, 12 amygdala enlargement, 11 extensive lesions, 12 normal MRI) who complained about their memory, but for whom the standard neuropsychological assessment did not reveal any memory impairment after a standard delay of 20 minutes, underwent two surprise memory tests after three weeks. They were compared to 35 healthy control subjects.Results:After three weeks, FCSRT and Epireal recall scores were significantly lower in patients than in controls (p<0.001). There was no significant correlation between FCSRT and Epireal scores (p=0.99). Seventy-six percent of TLE patients had objective impairment on at least one of these very long-term memory tests, regardless of the existence and type of lesion or response to antiseizure medication. Easily applicable, Epireal had a higher effect size, detected deficits in 28% more patients, and is a useful addition to the standard workup.Conclusion:Assessing long-term memory should be broadened to a wide spectrum of TLE patients with a memory complaint, regardless of the epileptic syndrome, whether or not associated with a lesion. This could lead to rethinking TLE nosology associated with memory.

Evaluation of Memory Complaints in People Living with HIV in Iran

Background: Several studies have reported that many people living with HIV (PLHIV) complain of memory impairments. Objectives: This study aimed to investigate these complaints both subjectively and objectively. Patients and Methods: For this purpose, 50 PLHIV and 50 of their companions as the control group were selected by the convenience sampling method in Shiraz, Iran, and completed Ray's auditory-verbal learning test and the Patient’s Assessment of Own Functioning Inventory (PAOFI). Data were analyzed using a t-test in SPSS. Results: Our findings showed a significant difference between PLHIV and the control group in terms of subjective memory complaints and objective memory functions. Conclusions: The overall result of the study showed that PLHIV reported more subjective memory complaints and poorer objective memory functions than the control group, regardless of the stage of the disease.

Incidence of Anxiety in Latest Life and Risk Factors. Results of the AgeCoDe/AgeQualiDe Study

Research on anxiety in oldest-old individuals is scarce. Specifically, incidence studies based on large community samples are lacking. The objective of this study is to assess age- and gender-specific incidence rates in a large sample of oldest-old individuals and to identify potential risk factors. The study included data from N = 702 adults aged 81 to 97 years. Anxiety symptoms were identified using the short form of the Geriatric Anxiety Inventory (GAI-SF). Associations of potential risk factors with anxiety incidence were analyzed using Cox proportional hazard models. Out of the N = 702 older adults, N = 77 individuals developed anxiety symptoms during the follow-up period. The incidence rate was 51.3 (95% CI: 41.2–64.1) per 1000 person-years in the overall sample, compared to 58.5 (95% CI: 43.2–72.4) in women and 37.3 (95% CI: 23.6–58.3) in men. Multivariable analysis showed an association of subjective memory complaints (HR: 2.03, 95% CI: 1.16–3.57) and depressive symptoms (HR: 3.20, 95% CI: 1.46–7.01) with incident anxiety in the follow-up. Incident anxiety is highly common in late life. Depressive symptoms and subjective memory complaints are major risk factors of new episodes. Incident anxiety appears to be a response to subjective memory complaints independent of depressive symptoms.

Sedentary Behavior, Sleep Quality, and Subjective Memory Function in Middle-Aged Adults

While there is evidence that prolonged sedentary behaviors (SB) are associated with poor memory performance, less is known about the effect of SB on subjective memory. Poor subjective memory could be an early symptom of mild cognitive impairment or dementia. Besides SB, sleep quality has been identified as an essential component of cognitive health. Yet little is known about the effects of different types of SB on sleep quality and how such effects could, in turn, affect middle-aged adults’ subjective memory. The sample included 306 adults ranging in age from 40 to 60 (M = 44.42) from Amazon MTurk. Mediation analysis with PROCESS (Hayes, 2013) was used to examine the mediational path, controlling for demographic variables. Exploratory factor analysis categorized 10 different sedentary activities into Common Engaging SB (e.g., sitting in cars), High Engaging/Leisure SB (e.g., doing hobbies when sitting), and Less Engaging/Passive SB (e.g., watching TV). Common Engaging SB included a variety of behaviors, including transportation, reading, talking on the phone, and socializing. Common Engaging SB had a significant direct effect on sleep quality (B = 0.19, p &lt; .001) and frequency of forgetting (B = -1.61, p &lt; .001), and sleep quality had a significant direct effect on frequency of forgetting (B = -1.90, p &lt; .001). Sleep quality mediated the association between Common Engaging SB and frequency of forgetting (indirect effect = -0.05, 95% bootstrap CI = -0.09, -0.02). Reducing sitting time, particularly Common Engaging SB, could be a useful strategy to improve subjective memory functioning.

208 Association between cardiovascular data and the development and progression of mild cognitive impairment: results from the retrospective cohort study

Aims Mild cognitive impairment (MCI) is characterized by objective evidence of cognitive impairment in one or more cognitive domains in the absence of significant interference in daily-life activities. Anyway, people with MCI are considered to be at heightened risk of further cognitive decline and progression to dementia. To date, few evidence regarding the association between cardiovascular data and MCI are present in the literature. To investigate the association between various cardiovascular data (traditional risk factors and outcomes) and the development and progression of MCI. Methods and results The study included 127 patients referred to the Neurological Unit of the Fondazione IRCCS Ca’ Granda Ospedale Maggiore Policlinico of Milan for subjective memory complaints and/or clinical suspect of cognitive impairment. Neuropsychological tests evaluating executive functions and cardiovascular data were collected at baseline and 2-year follow-up. Visit reports and medical records were reviewed to extrapolate the data. The study was conducted between 2012 and 2020. The 51 (40.2%) patients on antiplatelet therapy (94% on aspirin) had a worse baseline degree of cognitive impairment on neuropsychological tests of executive functions and had greater worsening of MCI at 2 years (Table 1). Patients on antiplatelet therapy were significantly older (75.85 vs. 71.7; P = 0.009), more ischaemic (21.6% vs. 1.3%; P &lt; 0.001), hypertensive (90.2% vs. 60.5%; P &lt; 0.001), and dyslipidaemic (62.7% vs. 19.7%; P &lt; 0.001) than patients without antiplatelet therapy. No other single cardiovascular data analysed (presence of hypertension, dyslipidaemia, ischaemic heart disease, diabetes, atrial fibrillation, and anticoagulation therapy) showed a statistical significant association with MCI presence or progression. Conclusions The present study suggests that the prevalence and progression of MCI is significantly higher among patients on antiplatelet therapy, who carry a greater cardiovascular burden. Although patients on antiplatelet therapy were older, more ischaemic, hypertensive, and dyslipidaemic than patients without antiplatelet therapy, none of these parameters were associated with MCI presence and/or progression and can therefore be considered a confounding factor.
