First,Do No Harm: Adverse Effects and the Need for Practice Standards in Neurofeedback

Adverse and iatrogenic effects associated with psychotherapy have been substantiated in research for more than 40 years. Controlled research also exists in the field of neurofeedback (electroencephalographic biofeedback) that documents that negative effects can occur from inappropriate training. This article presents accumulating evidence, taken directly from acknowledgments by neurofeedback practitioners of the existence of both transient side effects and of more serious adverse reactions that have occurred. Unlicensed and unqualified practitioners pose a risk to the public and to the integrity and future of the profession. It is vitally important that both professionals and professional societies emphasize standards of practice and that the public be protected from individuals seeking to use neurofeedback to work with medical, psychiatric, and psychological conditions for which they are not qualified and licensed to work. Some in the field propose pursuing biofeedback or psychophysiology licensure as a means to establish standards of practice and address ethical concerns. This is a reasonable option to consider, although it may take many years to implement in various states. In the meantime it is vitally important that individuals offering neurofeedback services for clinical diagnostic conditions be licensed to lawfully provide services for such conditions.     

The experience of caregiving: the influence of coping strategies on behavioral and psychological symptoms in patients with Alzheimer's disease

Objectives: To determine whether caregiver coping strategies are independently associated with behavioral and psychological symptoms (BPS) in Alzheimer's disease (AD) after accounting for patient characteristics.

Methods: Cross-sectional data analysis of 80 patients with AD and their primary caregivers. The presence of BPS was recorded using the Neuropsychiatric Inventory (NPI). The relationship between caregiver characteristics and BPS was assessed through one-way analysis of variance, two-tailed student t-tests or correlation coefficients. Multivariate linear regression was used to determine the combined effect of all caregiver factors that were significant on bivariate analysis regarding coping and BPS controlling for patient characteristics.

Results: Caregivers were on average 62 years old, 77% female, and most were the children or the spouse of the patient. Over 50% had significant depression or anxiety. Patients were on average 77 years old and 62% were female, and most had moderate to severe dementia. After adjusting for patient characteristics, patients cared for by more depressed, more burdened, or those using more disengagement coping strategies showed higher NPI mean composite scores.

Conclusion: Coping strategies are associated with BPS regardeless of patient characteristics. Interventions to reduce BPS should focus on which psychological coping strategies caregivers use. Understanding how coping strategies influence BPS may help tailor specific interventions for caregivers.     

Practice Effects and Longitudinal Cognitive Change in Normal Aging vs. Incident Mild Cognitive Impairment and Dementia in The Mayo Clinic Study of Aging

The objective of this study was to examine practice effects and longitudinal cognitive change in a population-based cohort classified as clinically normal at their initial evaluation. We examined 1390 individuals with a median age of 78.1 years and re-evaluated them up to four times at approximate 15-month intervals, with an average follow-up time of 5 years. Of the 1390 participants, 947 (69%) individuals remained cognitively normal, 397 (29%) progressed to mild cognitive impairment (MCI), and 46 (3%) to dementia. The stable normal group showed an initial practice effect in all domains which was sustained in memory and visuospatial reasoning. There was only a slight decline in attention and language after visit 3. We combined individuals with incident MCI and dementia to form one group representing those who declined. The incident MCI/dementia group showed an unexpected practice effect in memory from baseline to visit 2, with a significant decline thereafter. This group did not demonstrate practice effects in any other domain and showed a downward trajectory in all domains at each evaluation. Modeling cognitive change in an epidemiologic sample may serve as a useful benchmark for evaluating cognitive change in future intervention studies.     

Hypericum-induced mood disorder: switch from depression to mixed episodes in two patients

Objective. To point out the danger of worsening mood disorders with the use of hypericum. Methods. Longitudinal clinical observation of two cases treated with hypericum. Results. The two patients underwent mixed episodes following hypericum treatment. One of them needed hospitalization for suicidal risk. Conclusion. Caution is warranted in the use of hypericum in depressed patients with hidden bipolarity. Patients should be informed that hypericum may induce manic symptoms, increase cycling of mood states, or worsen the depressive state.     

Olanzapine in the treatment of depression with psychotic features: A prospective open-label study

Objective. Depression with psychotic features is a severe subtype of major depression associated with the presence of delusions, hallucinations and specific neurobiological features. Despite clinical consensus and guideline recommendations, data comparing the efficacy of combining antipsychotics with antidepressants compared to antidepressants alone remain inconclusive. The aim of the study was to investigate effectiveness and tolerability of the atypical antipsychotic olanzapine in acute depression with psychotic features. Methods. Seventeen inpatients with major depressive disorder with psychosis (MDDp) were treated with a combination of an antidepressant and olanzapine for 6 weeks in a prospective open-label study. Depressive and psychotic symptoms, extrapyramidal and general side effects were assessed every 2 weeks. Sixteen patients were eligible for final analysis. Results. The Brief Psychiatric Rating Scale (BPRS) showed a 30% symptom reduction after week 2, a 45% symptom reduction after week 4 and no considerable improvement thereafter. Depressive symptoms (Bech–Rafaelsen Melancholia Scale, BRMS) receded by 37% after week 2 and 50% after week 4. No extrapyramidal side effects occurred. Conclusion. Olanzapine is effective and tolerable in combination with an antidepressant in an MDDp inpatient sample. The results concur with data supporting good efficacy in negative and depressive symptoms of patients with schizophrenic and schizoaffective diseases.     

The Additive Effect on Suicidality of Family History of Suicidal Behavior and Early Traumatic Experiences

Family history of suicidal behavior and personal history of childhood abuse are reported risk factors for suicide attempts and suicide completion. We aim to quantify the additive effect of family history of suicidal behavior and different subtypes of childhood abuse on suicidal behavior. We examined a sample of 496 suicide attempters, comparing individuals with family history of suicidal behavior and personal history of childhood (physical or sexual) abuse, individuals with family history of suicidal behavior only, individuals with history of early traumatic experiences only, and individuals with none of these two risk factors with regards to suicidal features. An additive effect was found for the age at the first attempt in suicide attempters with both family history of suicidal behavior and either physical or sexual abuse. No significant interactions were found between family history of suicidal behavior and childhood trauma in relation to any characteristics of suicidal behavior. Subjects presenting family history of suicidal behavior and childhood abuse attempt suicide earlier in life than subjects with just one or none of them, particularly if they were sexually abused. Other suicidality indexes were only partially or not associated with this combination of risk factors. A careful assessment of patients with both family history of suicidal behavior and childhood abuse could help to prevent future suicide attempts, particularly in young people.
