Response: Acquiring reliable randomized evidence of the effects of cardiovascular interventions on cognitive decline is a priority. In this secondary analysis of 3 randomized intervention trials of cardiovascular event prevention, including 45 029 participants undergoing cognitive testing, we estimated the association of the avoidance of vascular events with differences in cognitive function in order to understand whether reports of non-significant results exclude worthwhile benefit.  Continue reading

School of Pharmacy
University of Pittsburgh

MedicalResearch.com: What are the main findings?

Response: Currently, there are 4 antidementia drugs approved by the FDA for the treatment of Alzheimer’s disease, including 3 acetylcholinesterase inhibitors (AChEIs)—donepezil, rivastigmine, and galantamine—and the N-methyl-D-aspartic receptor antagonist memantine. On the one hand, evidence about the effect of these drugs at delaying nursing home admission is still sparse and conflicting. On the other, all these antidementia medications have been associated with several cardiovascular side effects, such as bradycardia, ventricular tachycardia, syncope, QT interval prolongation, atrioventricular block or even myocardial infarction.

In this study, we aimed to compare time to nursing home admission and time to cardiovascular side effects across all drug therapies available for the treatment of Alzheimer’s disease. In doing so, we used 2006-2014 medical and pharmacy claims data from Medicare Part D beneficiaries with a new diagnosis Alzheimer’s disease who initiated antidementia drug therapy. Continue reading

Delirium: Treatment Options and Prevention Measures

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Delirium, also known as acute confusional state, is a serious disturbance in mental abilities that results in confused thinking and reduced awareness of the environment. Delirium can often be traced to one or more contributing factors, such as a severe or chronic illness, changes in metabolic balance (such as low sodium), medication, infection, surgery, or alcohol or drug intoxication or withdrawal. It’s critically important to identify and treat delirium because some of the contributing factors could be life-threatening. However, there is no sufficient evidence for choice of medication to treat or prevent the symptoms of delirium.

A recent paper, Association of Delirium Response and Safety of Pharmacological Interventions for the Management and Prevention of Delirium A Network Meta-analysis, published in JAMA Psychiatry provides important findings of this missing piece in that important clinical uncertainty. The leading author, Professor Kuan-Pin Su, at the China Medical University in Taichung, Taiwan, concludes the main finding about treatment/prevention of delirium: “In this report, we found that the combination of haloperidol and lorazepam demonstrated the best option for treatment of delirium, while ramelteon for prevention against delirium.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Perinatal depression, which includes depression that develops during pregnancy or after childbirth, is one of the most common complications of pregnancy and the postpartum period, affecting as many as 1 in 7 pregnant women. The Task Force found that counseling can help those who are at increased risk of developing perinatal depression, and clinicians should provide or refer pregnant and postpartum individuals who are at increased risk to counseling. Clinicians can determine who might be at increased risk of perinatal depression by looking at someone’s history of depression, current depressive symptoms, socioeconomic risk factors, recent intimate partner violence, and other mental-health related factors.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Slow wave sleep (deep sleep) is known to be very important for memory reorganization. The brain goes through the memory traces that were created during wakefulness and strengthens the important ones, while unimportant ones are weakened or deleted to make room for new learning the next day. This happens during the peaks of the eponymous slow waves, also called up-states, where the brain is highly active and interconnected. Up-states last for about 0.5 sec before transitioning into down-states, where the brain is relatively silent.

Based on these findings, we hypothesized that up-states constitute windows of opportunity to learn new information during slow wave sleep: The “channels are open”, and the brain is already performing memory functions.

The results of our study support this hypothesis. We found that, if we repeatedly managed to synchronize presentation of word pairs with up-states, memory for these pairs was best. Moreover, we find a dose-response function: The more often word pairs hit up-states, the better the memory. On top of that, fMRI during the retrieval test suggests that the same brain regions are involved in sleep learning as are involved in learning during wakefulness.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: There has been a growing utilisation of Caesarean sections in the past decades. To put it in a perspective, in the United Kingdom, the caesarean section rate was about 26% in 2015, while in 1990s it was about 12-15%. A similar increase has been observed in other countries, for example in the USA. So, while this study focuses on the United Kingdom, I believe that the evidence from this research can apply also to other countries.

I study the health consequences for mothers who give birth through an emergency caesarean. Thanks to previous studies, we are well-aware of the implications for mothers’ physical health; instead, this research sheds light on the impact on new mothers’ mental health. I find that new mothers who have an emergency caesarean delivery are at higher risk of developing postnatal depression in the first 9 months after the delivery.  Continue reading

MedicalResearch.com: What is the background for this study?

Response: Individuals affected by psychiatric disorders can demonstrate morphological brain abnormalities when compared to healthy controls. Although both genetic and environmental factors can account for these brain abnormalities, we expect that genetic susceptibility for psychiatric disorders has the greatest influence on the development of the brain.

Genetic susceptibility for psychiatric disorders can be estimated at the individual level by generating polygenic risk scores. Using this methodology, genetic susceptibility to psychiatric disorders and cognition has been associated with behavior problems in childhood. These findings suggest that heritable neurobiological mechanisms are at play in very early in the course of the illnesses.

Dr. Harch

Dr. Paul Harch MD
Clinical Professor and Director of Hyperbaric Medicine

MedicalResearch.com: What is the background for this study?

Response: The background is a 30 year clinical experience and investigation in which I explored the effects of low-pressure hyperbaric oxygen therapy (HBOT) on acute, subacute, and chronic neurological conditions.

Beginning with brain-injured Louisiana boxers and commercial divers in the late 1980s I attempted to see if patients with central nervous system disorders could respond to a lower dosing of the drug hyperbaric oxygen therapy than was traditionally used for other wound conditions like diabetic foot wounds, radiation wounds, and decompression sickness (the “bends”).  I was successful with the very first cases after which I expanded this treatment to nearly 90 neurological conditions.  The very first patient was a boxer 23 years after his last bout who was formally diagnosed with dementia pugulistica (dementia from boxing).

Since that time I have treated over 100 patients with cognitive decline or dementia, including 11 Alzheimer’s cases.  Nearly all of the Alzheimer’s and other dementia cases were documented with high-resolution brain blood flow imaging (SPECT).  The present case report was the first Alzheimer’s case that I was able to document with PET metabolic imaging.

MedicalResearch.com: What is the background for this study?  

Response: We naturally rock babies to sleep. Yet, we also have plenty of anecdotal reports of adults falling asleep faster when in a train or a car, as well as a feeling of relaxation in a hammock. Our companion paper on mice (Kompotis et a., 2019 – same issue in Current Biology) clearly established that the beneficial effects of rocking on sleep relied on the activation of the vestibular system and might thus suggest some shared neurophysiological mechanisms in mammals.

Blood Pressure Control – Good for Heart, Good for the Brain!

MedicalResearch.com Interview with:

Dr-Jeff Douglas Williamson

Dr. Williamson

Jeff D. Williamson, MD
Geriatric Medicine – Sticht Center
Wake Forest Baptist Medical Center

MedicalResearch.com: What is the background for this study?

Response: A growing amount of epidemiologic research has suggested that higher blood pressure is associated with higher risk for dementia, including Alzheimer’s dementia.

MedicalResearch.com: What are the main findings?

Response: More than 9,300 ambulatory, community dwelling persons over age 50, 30% of whom were over the age of 75, were randomly assigned to a blood pressure goal of 120 vs 140.  Persons in the 120 group had a 19% lower risk for developing MCI an transitional stage between normal and dementia (P<.008).  There was a 17% lower risk for developing dementia but this only achieved a p value = 0.10.  The combined risk for both MCI and dementia was 15% lower in the 120 group (p<0.04).  The dementia outcome was the primary outcome but all the outcomes were pre-specified in the protocol at the beginning of the trial.  Unfortunately the blood pressure intervention was stopped after only 3.3 years due to CVD and mortality benefit and this may well have influenced the ability to reach the expected number of dementia cases.

Less Risk of Cognitive Decline After Elective Hospitalizations

MedicalResearch.com Interview with:
Bryan D. James, PhD

Assistant Professor
Rush Alzheimer’s Disease Center
Chicago, IL 60612 

MedicalResearch.com: What is the background for this study?

Response: It has long been reported by patients, their family members, and physicians that many older adults experience long-term declines in their memory and thinking abilities after hospitalization. Studies have recently begun to confirm these reports by following older patients for years after hospitalization and repeatedly testing their cognitive abilities. A number of questions have yet to be answered, including which types of hospitalizations are most strongly related to cognitive decline.

In this study, we sought to answer whether going to the hospital for elective procedures was as risky to the cognitive health of older adults as urgent or emergency (that is, non-elective) hospitalizations.

Psychiatric Problems Related to Lead Exposure Detected As Early As Age 11

MedicalResearch.com Interview with:
Aaron Reuben, MEM
Department of Psychology and Neuroscience
Duke University, Durham, North Carolina

MedicalResearch.com: What is the background for this study? What are the main findings?

(1)  Study members with greater lead exposure in childhood tended to endorse more psychiatric symptoms when assessed for psychiatric disorders in adulthood (between 18 and 38 years of age).

  1. These individuals tended to report more internalizing (e.g., depression, anxiety) and thought disorder (e.g., OCD, schizophrenia, mania) symptoms.
  2. Compared to other findings from this sample, the associations reported in this article are similar to those reported for lead and IQ, and are stronger than those reported for lead and criminal offending.
    1. Informants who knew Study members well reported higher levels of difficult adult personality traits among Study members with greater lead exposure in childhood.
    2. Specifically, Study members with greater blood lead levels at age 11 were rated as more neurotic, less agreeable, and less conscientious by 38 years of age.
    3. These personality traits have been previously linked to a number of poor life outcomes, including greater psychopathology, worse physical health, less job satisfaction, and troubled interpersonal relationships
  3. Psychiatric problems related to lead exposure could be detected as early as 11 years of age. In the 1980’s, parents and teachers of children with higher blood-lead levels had described them as displaying more antisocial behavior, hyperactivity, and negative emotions (e.g., sadness, anxiety).

Adolescents: Comparison of Recovery from Concussions vs Fractures

MedicalResearch.com Interview with:

Kelly Russell PhD Department of Pediatrics and Child Health University of Manitoba

Dr. Russell

Kelly Russell PhD

MedicalResearch.com: What is the background for this study?

Response: Health-related quality of life (HRQOL) is an important patient-reported outcome that measures the patient’s perception on how their condition effects various aspects of their life, such as their physical, emotional, social and school quality of life.  HRQOL can measure the more subtle or hidden consequences of a condition, such as concussion.  Patient reported outcomes are important because they give a more complete picture of the patient’s condition than just reporting symptoms or outcomes that are only measured by their clinician.  We wanted to compare the effects of sport-related concussions versus sport-related limb fractures on HRQOL in adolescents after their injury and during their recovery.

We chose to compare adolescents with sport-related concussions to a sport-related limb fracture group because we wanted to be able to attribute the results to having a concussion since not being able to play sports with their friends and teammates may decrease HRQOL regardless of the actual type of injury.  We also wanted to identify which clinical variables were associated with worse HRQOL in adolescent patients with sports-related concussion.

Depression May Be a Driver of Alopecia Areata

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: It is well known that patients with alopecia areata, a form of autoimmune hair loss, are at a higher risk of suffering from depression than the general population. But in practice, we often hear patients tell us that they believe their hair loss developed as a result of stress or problems with mental health – certainly the phrase “so stressed your hair is falling out” is something most people have heard of. Despite this, there has actually been very little research investigating the role that mental health may have on development of alopecia areata.

Interestingly, depression has recently been associated with increased systemic inflammatory markers, so there is biologic plausibility that depression could increase the risk of alopecia areata. Our group was interested in addressing this question, and used a large population-level health records database with up to 26 years of follow-up to study it. We ultimately found that not only does depression increase one’s risk of alopecia areata, but that it increases their risk by nearly 90% compared to people who have never had depression. We also found that using antidepressants can significantly decrease the risk of developing alopecia areata in patients with depression. So there appears to be an important link between mental health and development of hair loss from alopecia areata.

Zika: Simple General Movement Assessment Tool Can Predict Babies at Risk of Developmental Problems

Dr. Nielsen

Karin Nielsen-Saines, MD, MPH

David Geffen School of Medicine at UCLA

MedicalResearch.com: What is the background for this study?

Response: Our study used a very simple evaluation called GMA (General Movement Assessment tool) which checks baby movements at approximately 3 to 5 months of age.

We examined 111 babies exposed to maternal illness during the Zika epidemic in Brazil and 333 control babies without this exposure by GMA at 3 months  and then tested them through standard neurodevelopmental tests at the age of 12 months.

We found that this simple evaluation, which consists of filming a baby lying down on their back for one minute and studying their movements worked extremely well in predicting which babies would or would not have future problems in their neurodevelopment. The study advances knowledge in the area because a simple one minute video of a baby can predict neurodevelopment, something that is extremely hard to determine in young babies.  This is true even in places where sophisticated brain scans are available. By identifying which babies are at risk of developmental problems early on, professionals can rapidly refer these babies to  stimulation programs when they are very young, which increases their chances of having better outcomes. Because the brains of young children respond much better  to stimulation, the timing of interventions to improve their development is very important, that is why they need to be identified early.

Take Control of Your Life and Treat Your Gambling Addiction

gambling addictionAn addiction to gambling can be an isolating ordeal that causes havoc among someone’s personal relationships, destroys personal finances, and exacerbates any mental health issues that a person may have.

Addiction is rarely an isolated incident. Typically there are many factors at play that can manifest themselves in the form of gambling. By tackling these underlying causes one can treat their addiction and eliminate the toxic habits that created it. In addition to confronting this by oneself, it is important for those who suffer from this to confide in those close to them as well as seeking advice from their doctor.

One major issue brought on by any kind of addiction is the sense of alienation that someone can experience. This is where it is important for them to open up to those who are close to them, like a loved one or a close friend. It will help alleviate the burden of struggling alone and will help others to understand what they are going through. Getting in touch with self-help groups can be another means of alleviating the feelings of alienation that addicts can experience while they are treating their compulsive gambling. This provides an outlet for an addict to express what they are going through while simultaneously getting the perspective of others who have struggled in a similar fashion.

One of the most important steps to take is the very first one. That is to be able to admit that there is a problem with gambling. Once this has been done, the problem becomes tangible and the addiction can be confronted directly.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: I found that when I was referred women with midurethral sling complications, they were often quite emotional and described a significant period of time when they struggled with the complications before they were referred to someone to assess them.

The study looked at the rate of depression and self-harm behavior of women who had surgery for midurethral sling complications compared to women who did not have midurethral sling complications.

I found that there was an increased risk of both of these outcomes among women who had surgery for complications, however this risk was primarily present in younger women.

MedicalResearch.com: What is the background for this study?

Response: Alzheimer’s disease and sleep are currently thought to have a two-way or bidirectional relationship.

First, sleep disturbances may increase the risk of developing AD.

Second, changes in sleep-wake activity may be due to Alzheimer’s disease pathology and our paper was primarily focused on this aspect of the relationship.    If sleep changes were a marker for AD changes in the brain, then this would be very helpful in future clinical trials and possibly screening in the clinic.

MedicalResearch.com: What is the background for this study?

Response: There are significant amounts of research on children of parents with alcohol use disorders – where the children are shown to be at risk of several adverse outcomes, including mental disorders, substance use disorders, suicide, impaired school performance, and employment problems. There is very little previous research on how other, more normal levels of parental drinking may influence child outcomes, such as mental health. This is a grave oversight, as there are vastly more parents with normal drinking patterns than there are parents who suffer from an alcohol use disorder. This means that there are potentially a lot more cases of adverse effect for children, and the number of children at risk may be higher than previously assumed.

In addition to parents’ alcohol use, several other risk factors in the family that may affect child mental health outcomes, such as parents’ mental health and socio-economic status. Researchers have tended to look at these risk factors separately, but as these risks tend to co-occur, it may be more informative to consider them together.

To our knowledge, this is the first study that examines possible harm from normal levels of parental drinking, alone or in combination with other parental risk factors, on children’s anxiety and depression.

The sample consists of more than 8700 triads: children and both their parents. We combined information from three health registries with survey data where both adolescents and their parents provided information about health and social conditions. The health registers include information about the children ‘s actual contact with the health care system; we used information about whether children received diagnoses and/or treatment for anxiety and/or depression.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Age-related hearing loss is extremely common, yet few people do anything about it. We studied a population of over 5,000 individuals and found that hearing loss was related to feelings of depression. The worse the hearing loss, the worse the symptoms of depression. Even people with just mild hearing loss had nearly two times the odds of depressive symptoms compared to normal hearing people. Among people with moderate hearing loss, the odds of depressive symptoms were four times as high. These statistics take into account various factors that can cause both hearing loss and depression, such as age and demographic background.  Continue reading

The medication was primarily studied and evaluated in patients with amyotrophic lateral sclerosis (ALS)   or (multiple sclerosis) MS, but anecdotal evidence suggested it was being prescribed to patients with dementia. We used data from two nationwide healthcare databases to understand how the medication was being used in routine care.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Autism is a lifelong condition, and challenges associated with autism persist from childhood into adulthood. Despite this, research and treatment have been largely dedicated to children. Because of that, we had very little understanding of what areas – what cognitive domains – are most severely impacted in adults with autism. Importantly, the lack of such information also limits treatment development in this area.

What is known already is that adults with autism display deficits in social cognition (which refers to the role that cognitive processes play in our social interactions). Although our meta-analysis supported these theories, it also highlighted several other challenges in cognitive processing, such as deficits in processing speed and verbal learning and memory. And these impairments were observed in adults with autism without an overall intellectual disability.
