Alzheimer's - Dementia, Author Interviews, Mental Health Research / 08.10.2019

MedicalResearch.com Interview with: Marjaana Koponen, PhD Postdoctoral Researcher Kuopio Research Centre of Geriatric Care School of Pharmacy University of Eastern FinlandMedicalResearch.com: What is the background for this study? What are the main findings?Response: It is known that antipsychotics are commonly used in the treatment of behavioral and psychological symptoms of dementia, although their use has been linked to serious adverse events.In this study, we found that community dwellers with Alzheimer’s disease who initiated antipsychotic use accumulated more hospital days than non-initiators. This may partially reflect adverse effects and events of antipsychotic use. On the other hand, antipsychotic users accumulated more hospital days due to dementia, mental and behavioral disorders and their caregivers’ days off.Thus, another reason for a higher accumulation of hospital days is care burden and the difficulties in treating the most severe behavioral and psychological symptoms of dementia.

MedicalResearch.com Interview with: Chen Liu, Ph.D. Assistant Professor Departments of Internal Medicine and Neuroscience Division of Hypothalamic Research The University of Texas Southwestern Medical Center Dallas, Texas 75390-9077MedicalResearch.com: What is the background for this study? Response: Atypical antipsychotics are second-generation antipsychotics (SGAs) that have been increasingly used to treat a variety of neuropsychiatric conditions such as schizophrenia, depression, and autism. Many patients taking these medications, however, are left in an agonizing dilemma.On one hand, they rely on these drugs’ psychotropic effect for normal functioning in daily life. On the other, many SGAs, including the most widely prescribed olanzapine and clozapine, can cause a metabolic syndrome that is known for excessive weight gain, dyslipidemia, and type-2 diabetes_ENREF_2. Notably, while full-blown type 2 diabetes and morbid obesity typically take years to unfold in the general population, these conditions progress at a much faster pace (within months) following second-generation antipsychotics treatment. Other factors such as ethnicity, age, and sex can also aggravate SGA-induced metabolic syndrome. Together, these peculiar features strongly suggest a distinct etiology underlying SGA-induced metabolic syndrome that has yet been fully elucidated. Currently, there is no medication specifically targeting SGA-induced metabolic syndrome. For many youths and adults taking second-generation antipsychotics, metabolic complications are difficult to manage as lifestyle changes, nutritional consulting, and commonly used anti-diabetic medications only provide limited relief.(more…)

Correll, MD Professor of Psychiatry and Molecular Medicine Hofstra Northwell School of Medicine Hempstead, New York, USA Investigator, Center for Psychiatric Neuroscience Feinstein Institute for Medical Research Manhasset, New York, Medical Director, Recognition and Prevention The Zucker Hillside Hospital, Department of PsychiatryMedical Research: What is the background for this study? Dr. Correll: Antipsychotics have been used increasingly for psychotic, but also for many non-psychotic conditions, including for disorders and conditions for which they have not received regulatory approval. Moreover, antipsychotics have been associated with weight gain and abnormalities in blood fat and blood glucose levels. Although data in youth have been less available than in children and adolescents, youth appear to be more sensitive to the cardiometabolic adverse effects of antipsychotics than adults in whom significant weight gain might have already occurred due to long-term prior antipsychotic treatment. Nevertheless, type 2 diabetes, which is related to weight gain, overweight and obesity, seemed to be more common in adults than youth, likely due to the fact that it takes a long time for the body to develop diabetes. Recently, several individual epidemiologic or database studies with sufficient long-term follow-up durations suggested that the type 2 diabetes risk was higher in youth exposed to antipsychotics than healthy control youth and, possibly, even compared to psychiatrically ill patients treated with non-antipsychotic medications. However, a meta-analytic pooling of all available data has not been available to estimate the absolute and relative risk of type 2 diabetes in youth receiving antipsychotic treatment.Medical Research: What are the main findings? Dr. Correll: The main findings of the study that meta-analyzed data from 13 studies with 185,105 youth exposed to antipsychotics (average age 14.1 and 59.5 percent male) are that the absolute rates of type 2 diabetes are fortunately still relatively low, i.e. a cumulative type 2 diabetes risk of 5.7/1,000 patients and an exposure adjusted incidence rate of 3.1/1,000 patient-years. Nevertheless, the cumulative risk of type 2 diabetes and its exposure adjusted incidence rate per patient were 2.6 times and three times higher compared with 298,803 healthy controls. Furthermore, the cumulative risk of type 2 diabetes and its exposure adjusted incidence rate per patient were 2.1 times and 1.8 times higher compared with 1,342,121 psychiatric patients not exposed to antipsychotics. Main modifiable risk factors for type 2 diabetes development in antipsychotic-treated youth were treatment with the antipsychotic olanzapine and longer antipsychotic exposure time.(more…)

Dr. Julie Magno Zito, PhD University of Maryland, Baltimore, MD 21201MedicalResearch.com Interview with: Dr. Julie Magno Zito, PhD University of Maryland, Baltimore, MD 21201MedicalResearch: What is the background for this study?Dr. Zito: Atypical antipsychotic (AAP) use in children and adolescents has grown substantially in the past decade, largely for behavioral (non-psychotic) conditions. Poor and foster care children with Medicaid-insurance are particularly affected. This ‘off-label’ usage has insufficient evidence of benefits regarding improved functioning (i.e. appropriate behavior and performance, socially and academically) while the little evidence that accrues tends to emphasize ‘symptoms’, i.e. less acting out. Recent evidence shows that youth treated with atypical antipsychotics are at risk of serious cardiometabolic adverse events including diabetes emerging after atypical antipsychotics are ‘on board’.(more…)

This ‘off-label’ usage has insufficient evidence of benefits regarding improved functioning (i.e. appropriate behavior and performance, socially and academically) while the little evidence that accrues tends to emphasize ‘symptoms’, i.e. less acting out. Recent evidence shows that youth treated with Atypical antipsychotics are at risk of serious cardiometabolic adverse events including diabetes emerging after atypical antipsychotics are ‘on board’.MedicalResearch: What are the main findings?Dr. Zito: The continued expansion in Atypical antipsychotics use for behavioral conditions, particularly in poor and foster care youth prompted several government reports asking states to implement oversight programs. In our survey of state Medicaid agencies, we identified programs implementing a new and promising approach to increase the likelihood that these medications are used appropriately. These ‘peer review’ programs have been launched in 15 of the 31 prior authorization state Medicaid programs. There is a distinct advantage in having a qualified peer review, on a case-by-case basis, of the rationale for use of an atypical antipsychotic in a condition or age group that is ‘off-label’ according to the FDA product information label.(more…)

Correll, MD Professor of Psychiatry and Molecular Medicine Hofstra North Shore LIJ School of Medicine Medical Director, Recognition and Prevention (RAP) Program The Zucker Hillside Hospital Investigator Feinstein Institute for Medical Research North Shore Long Island Jewish Health SystemMedical Research: What are the main findings of the study?Dr. Correll: The main findings of the study of 398 patients with first-episode schizophrenia-spectrum disorders who were on average in their mid twenties are that:
  • 1) despite their young age, an average of only 47 days lifetime antipsychotic exposure and overweight/obesity figures that were comparable to similarly aged US population members, there was a clear pattern of increased smoking and several metabolic risk parameters compared to similarly aged persons in the general US population;
  • 2) dyslipidemia, a constellation of at least one relevant abnormal blood fat value, was as frequent as in a 15-20 years older general US population;
  • 3) body composition related risk markers were significantly associated with longer total psychiatric illness duration, whereas metabolic risk markers were significantly associated with the overall very short mean lifetime antipsychotic treatment duration; and
  • 4) relevant for treatment choice and recommendations for patients, significantly higher continuous metabolic risk factor values were associated with olanzapine treatment and, less so, with quetiapine treatment. (more…)
