More physical exercise associated with lower mental health risk

13/08/2019

While exercise has long been thought to help boost mental health and there’s evidence to support this, less is known about whether physical activity can actually prevent the onset of mental health conditions such as anxiety and depression. Indeed, previous studies have suggested that low levels of physical activity are associated with a greater incidence of several common mental health problems, but few studies have investigated whether the opposite is true: more exercise = less risk of developing mental health disorders – until now. By conducting a systematic review and meta-analysis of four different studies, the researchers from University College London were able to assess the impact of physical exercise on mental health risk. Publishing their findings in the Journal of Affective Disorders, the researchers said low and medium levels of cardiorespiratory fitness are associated with a 47% and 23% greater risk of common mental health disorders, compared with high levels of cardiorespiratory fitness. In other words, doing more physical exercise does seem to have a positive impact on a person's mental health risk. The research makes for interesting reading when you consider that mental health issues are growing and not everyone benefits from therapies and medication. The researchers are now planning to explore this avenue further to see if they can identify the underlying mechanisms of the relationship between exercise and mental health.  

Could eating dark chocolate lower your risk of depression?

08/08/2019

Eating chocolate makes us feel good, right? But is there actually any evidence that it can combat conditions like depression? Well, a new survey-based study of over 13,000 people suggests there is, but only if you eat dark chocolate. Having analysed data from the United States National Health and Nutrition Examination Survey, the researchers concluded that there was no link between eating dark chocolate and a reduction in depressive symptoms. However, when they looked specifically at dark chocolate consumption, they found people who ate this type of chocolate were 70% less likely to report depressive symptoms than individuals who ate no chocolate at all. Furthermore, the analysis also showed that people who ate the most chocolate (regardless of type) were less likely to experience depression than people who ate no chocolate. While chocolate lovers might rejoice at these findings, more research is needed. That’s because the study is merely observational, so no causational conclusions can be drawn. If subsequent research is performed and does suggest that a link exists between eating chocolate and a lower risk of depression, the biological reasons why will need to be investigated. For now, if you’re a fan of dark chocolate in moderation, you could be reducing your chances of developing depression.  

Ear ‘tickling’ could prevent age-related diseases

01/08/2019

New research suggests that tickling the ear with a small electric current could help rebalance the body’s nervous system in people over-55 and help them age more healthily. The therapy works by stimulating the vagus nerve, the longest of the nerves that connect the brain with other parts of the body such as the heart, lungs and gut. The vagus nerve is usually difficult to access and usually requires surgical intervention so that electric stimuli can be delivered. However, one small branch of the vagus nerve reaches a part of the outer ear and that’s where the researchers from the Universities of Leeds and Glasgow — both in the United Kingdom – stimulated it from. Patients who received the electric stimuli for 15 minutes a day over a 14-day period noted improvements in body, sleep and mood. As we age, our body’s nervous system gradually becomes out of balance and the sympathetic branch begins to dominate. This makes us more prone to diseases, such as hypertension and heart problems, as well as anxiety and depression. The researchers found that the electric ear tickling therapy – named so because that’s how it feels – helped rebalance the body’s nervous system by increasing parasympathetic activity and decreasing sympathetic activity. People with the greatest imbalance at the start of the trial showed the biggest improvement at the end.

Anticholinergic drugs linked to increased risk of dementia

25/06/2019

New research shows that some drugs commonly prescribed for treating depression, epilepsy and other conditions may increase a person’s risk of dementia. The drugs, which belong to a family of medicines called anticholinergics, have previously been lined to short-term problems with thinking. According to the new study of patients in the UK, the findings of which are published in Jama Internal Medicine, using such drugs could lead to possible long-term brain side effects. However, experts are stressing that the study findings do not prove there is a direct risk and that patients already taking these drugs – literally millions of people in the UK - should not stop doing so. Anticholinergic drugs block the action of a neurotransmitter (chemical messenger) in the brain which controls signals around the body. They are used to treat a variety of conditions, including depression, epilepsy, psychosis, overactive bladder, Parkinson’s disease, chronic obstructive pulmonary disease and some allergies. For the study, researchers looked at nearly 300,000 patients (58,000 with dementia) and their use of medication going back more than 20 years. They found a strong link between the use of certain anticholinergic drugs – namely ones used to treat depression, Parkinson’s, psychosis, bladder conditions and epilepsy - and an increased risk of dementia in individuals aged 55 and over. Anticholinergic drugs used to treat asthma, muscle problems, heart rhythm issues and gastrointestinal problems were not found to pose a dementia risk. Speaking about the findings of the study, Dr Jana Voigt, from Alzheimer's Research UK, said: “There is a growing body of evidence that suggests certain anticholinergic drugs are linked to an increased dementia risk. “While finding a link between certain strong anticholinergic drugs and an increased risk of dementia, it doesn’t tell us if these drugs cause the condition.”

The seven dementia risk factors: How many are you aware of?

07/02/2019

A new study has revealed that half of UK adults cannot name a single dementia risk factor. If asked, how many could you name? The study by Alzheimer's Research UK found that just 1% of UK adults could name the seven known dementia risk or protective factors. Heavy drinking, smoking, genetics, high blood pressure, depression and diabetes are the six dementia risk factors, while physical exercise is a protective factor. According to the study, more than half of UK adults know someone with dementia, yet only half also recognised that the disease is a cause of death. Furthermore, a fifth of people quizzed for the report incorrectly said that dementia is an inevitable part of getting old. Right now, there are more than 850,000 people in the UK living with dementia and that number is expected to top one million by 2025. Alzheimer's disease is the most common type of dementia, accounting for around two-thirds of all cases. Hilary Evans, chief executive of Alzheimer’s Research UK, said: “It is a sad truth that more people are affected by dementia than ever before and half of us now know someone with the condition. Yet despite growing dementia awareness, we must work harder to improve understanding of the diseases that cause it.” You can read the full Alzheimer’s Research UK report here: https://www.dementiastatistics.org/wp-content/uploads/2019/02/Dementia-Attitudes-Monitor-Wave-1-Report.pdf#zoom=100

Less sitting, more moving tied to longer life

31/01/2019

People who have sedentary jobs could significantly boost their lifespans by taking short, regular movement breaks, a new study has found. It’s no secret that individuals who spend a lot of time sitting down are more likely to develop certain adverse health conditions, such as diabetes, obesity and cardiovascular diseases, as well as having increased risk of osteoporosis, depression, anxiety, colon cancer and high blood pressure. However, just a small amount of exercise, the study suggests, could lower the risk of early death. According to the research – the findings of which are published in the Annals of Internal Medicine – individuals who sat for less than 30 minutes at a time had the lowest risk of early death. For example, workers who had a movement break (involving some low-intensity exercise) every 30 minutes had a 17% lower risk of death than their counterparts who did not have any breaks. Moreover, individuals who broke up periods of sitting every 30 minutes with moderate- to high-intensity exercise lowered their risk of early death by 35%. Speaking about the findings of the research, Keith Diaz, an assistant professor of behavioural medicine at Columbia University Vagelos College of Physicians and Surgeons in New York City and study lead, said: “If you have a job or lifestyle that involves a lot of sitting, you can lower your risk of early death by moving more often, for as long as you want and as your ability allows — whether that means taking an hour-long high-intensity spin class or choosing lower-intensity activities, like walking.”

Too much exercise can negatively impact mental health - study

14/08/2018

A large-scale study has found that just 45 minutes of physical exercise three to five times a week can improve mental wellbeing. [Related reading: People who abstain from alcohol in middle age may have higher risk of dementia] According to the US study of 1.2 million people, people who exercised regularly had fewer “bad days” a month than their non-exercising counterparts. Furthermore, while activities such as cycling, aerobics and team sports had the greatest positive impact, all types of physical activity, including things like doing household chores and looking after kids, were found to improve mental health. Moreover, people who had previously been diagnosed with a mental health condition like depression were found to afford the greatest benefits. The optimal routine identified by the researchers was being physically active for 30 to 60 minutes every second day. More interesting is the researchers’ finding that too much exercise can have a negative impact. Dr Adam Chekroud, study author and assistant professor of psychiatry at Yale University, said: "Previously, people have believed that the more exercise you do, the better your mental health, but our study suggests that this is not the case. "Doing exercise more than 23 times a month, or exercising for longer than 90-minute sessions is associated with worse mental health." The findings of the study are published in The Lancet Psychiatry Journal.

Singing helps mothers recover from post-natal depression faster - study

11/01/2018

We’ve reported before how singing in community groups can help people recover from mental illness. Now, new research suggests singing may also be beneficial for mothers suffering with post-natal depression. According to the study, which was published in the British Journal of Psychiatry, women with post-natal depression who took part in group singing sessions with their babies experienced a much quicker improvement in their symptoms than their counterparts who did not. Post-natal depression is thought to affect one in eight new mothers and early recovery is believed to be crucial for limiting its effects on both mother and baby. The study highlights how singing can be a more effective treatment for post-natal depression than creative play sessions and typical post-natal care – which usually includes family support, antidepressants and/or mindfulness. Speaking about the findings of the research, Principal investigator Dr Rosie Perkins said: "Post-natal depression is debilitating for mothers and their families, yet our research indicates that for some women something as accessible as singing with their baby could help to speed up recovery at one of the most vulnerable times of their lives."

More exercise could be the key to quitting smoking

02/01/2018

It’s January 2 and for many people that means it’s time to start thinking about those New Year’s resolutions. The inevitable over-indulgence during the festive period will have triggered many of us to consider eating more healthily and exercising more this year, while others will be looking to give up smoking. The problem is that nicotine is a very addictive drug and many people struggle to give up cigarettes easily. But new research shows how exercising may reduce tobacco withdrawal symptoms. So, if you’re planning to try and quit, exercise could be the answer. Irritability, trouble sleeping and even depression are all withdrawal symptoms associated with giving up smoking. However, it’s been shown that exercise can reduce nicotine withdrawal symptoms. In fact, some older studies have discovered that even 10 minutes of exercise can immediately reduce the effects of tobacco cravings. A team from St George's, University of London, led by Dr. Alexis Bailey, a senior lecturer in neuropharmacology, found that mice addicted to nicotine who undertook two or 24 hours a day wheel running displayed a significant reduction of withdrawal symptom severity compared with the sedentary group. Furthermore, in the group of mice that exercised, researchers were able to see an increase in the activity of alpha7 nicotinic acetylcholine, a type of nicotine brain receptor. Most startling of all was the fact just two hours of exercise daily had as much effect on relieving the symptoms of nicotine withdrawal as exercising continuously for 24 hours. SO, if you really want to crack your smoking habit and give up this year, maybe more exercise could be the key to your success.

Over a third of mothers experience mental health issues

30/11/2017

More than a third of mothers have experienced a mental health issue related to parenthood, an online survey has found. According to the YouGov poll of 1,800 British parents, in comparison, just 17% of fathers had experienced similar parenthood-related issues. Of the mothers who experienced a mental health issue, more than two-thirds sought professional help as a result. Their conditions included acute stress, severe anxiety and postpartum depression. One of the biggest factors that weighs on the minds of new mums is criticism. Of those surveyed, 26% said their parents were the most critical of their parenting skills, followed by 24% who cited their spouse/partner and 18% other family members. Quite shockingly, 14% said they had been criticised by complete strangers. In comparison, 5% of the 800 fathers said the same. Trouble at work is also not uncommon for new parents. About 30% of mothers who responded said they had felt discriminated against at work because they were a parent, compared with 14% of working fathers. In terms of emotional support, 60% of women said they had received it from their friends, 56% from their partner and 18% went online. However, 15% of mothers and 25% of fathers say they didn't receive any emotional support at all. If nothing else, the survey highlights the struggles many mothers and fathers go through following the birth of a child. Support is crucial in helping these parents get through such difficult times. 

Just a few nights of bad sleep can impact your mental health

02/11/2017

The benefits of a full night’s sleep are well known. Insomniacs across the world will tell you what sleep deprivation can do to your mind and body. But now it seems that just a few nights of bad sleep could impact your mental health too. A team of scientists from the University of Oxford in the UK ran a small experiment using four volunteers who normally sleep just fine. The volunteers were fitted with monitors to track their sleep. For the first three nights of the study, they were allowed to sleep normally. For the next three nights, their sleep was restricted to just four hours per night. Each day of the study, the volunteers filled out questionnaires about how they were feeling and kept video diaries. Three out of the four volunteers said the experience was unpleasant, while one said he was largely unaffected. However, tests showed that his mood was significantly impacted, with positive emotions falling and negative emotions rising. Doctoral student Sarah Reeve, one of the scientists who ran the experiment, was surprised by how quickly the volunteers’ moods changed. "There were increases in anxiety, depression and stress, also increases in paranoia and feelings of mistrust about other people", she said. "Given that this happened after only three nights of sleep deprivation, that is pretty impressive."

Even one hour of exercise per week could prevent depression

03/10/2017

Depression affects around 6.7% of US adults every year. On a global level, the World Health Organization (WHO) estimates that more than 300 million people are currently living with the disorder. When it comes to treatment, medication, psychotherapy, cognitive behavioural therapy or a combination of these approaches is usually used. But new research adds weight to the argument for regular exercise as a depression treatment. Australia-based non-profit group Black Dog Institute conducted an analysis of data collected from 33,908 Norwegian adults who were followed over an 11-year period. Publishing their results in the American Journal of Psychiatry, the team, led by Prof. Samuel Harvey from the Black Dog Institute, found that not only does a little exercise bring substantial benefits, but a lack of exercise actually contributes to depression. Individuals who didn’t undertake any physical activity were found to be 44% more likely to develop depression than those who did just 1 or 2 hours per week. As a result, the authors concluded that approximately 12% of depression cases could have been prevented if the individual did at least 1 hour of exercise per week. "We've known for some time that exercise has a role to play in treating symptoms of depression, but this is the first time we have been able to quantify the preventive potential of physical activity in terms of reducing future levels of depression,” said Prof. Harvey.

Marmite yeast extract may help to boost brain function - study

06/04/2017

The slogan for British yeast extract Marmite is 'You either love it or hate it'. And while many people in America may not have even heard of it, a new study will come as good news for lovers of the popular food stuff. A by-product of beer brewing, Marmite is a sticky, almost black coloured food paste with a very distinctive, powerful, salty flavour. People in the UK usually eat it in sandwiches or on toast. According to a study conducted by researchers from the University of York in the UK, Marmite could help boost brain function. The study found that participants who ate one teaspoon of Marmite every day displayed a reduced response to visual stimuli - an indicator of increased levels of gamma-aminobutyric acid (GABA) in the brain. Simply put, GABA "clams" the human brain and helps restore the optimal balance of neuronal activity required for healthy brain functioning. Low GABA levels have previously been linked with anxiety, depression, epilepsy, and autism. That's why researchers have been looking at ways to increase GABA levels in the brain. Speaking about the findings of the research, Senior author Dr. Daniel Baker, of the Department of Psychology at York, said: "Since we've found a connection between diet and specific brain processes involving GABA, this research paves the way for further studies looking into how diet could be used as a potential route to understanding this neurotransmitter." The study serves as a great reminder of how diet has the ability to alter brain processes.

Study: Mental Health Conditions Common Before Bariatric Surgery, but Fall Afterwards

20/01/2016

Patients who are seeking and undergoing bariatric surgery commonly suffer from mental health conditions, such as depression and binge eating disorders. However, following successful bariatric surgery, the rates of these conditions fall, according to a study published in JAMA. Bariatric surgery is a highly accepted method of promoting weight loss in obese individuals and can also serve to reduce their risk of developing conditions such as heart disease, stroke, type 2 diabetes and certain kinds of cancer. Dr. Aaron J. Dawes, from the David Geffen School of Medicine at the University of California, Los Angeles, led a research team which wanted to discover how common mental health conditions were in people seeking and undergoing bariatric surgery. The findings of their research show that 23% of bariatric surgery patients were affected by a current mental health disorder, with depression (19%); a binge-eating disorder (17%); and anxiety (12%) the most common. Following surgery, a fall in the rate of depression was observed. Of the 27 studies analysed by the research team, seven revealed an 8-74% drop in the rate of depression after surgery, while six reflected a 40-70% reduction in the rate of depressive symptoms. The report authors noted: "Previous reviews have suggested that self-esteem, mental image, cognitive function, temperament, support networks and socioeconomic stability play major roles in determining outcomes after bariatric surgery." They suggest incorporating these factors into future studies, which would help form part of "an optimal strategy for evaluating patients' mental health prior to bariatric surgery."   Photo via: Bassett Healthcare Network 

Thyroidectomies: What You Need to Know

28/01/2015

The thyroid gland is shaped like a butterfly and found at the base of your neck. It regulates every aspect of your metabolism by producing hormones. This includes everything from how fast you burn calories to how quickly your heart beats. Think of your thyroid as your body’s general thermostat. However, your thyroid can sometimes over-perform or under-perform and that can cause a number of issues to occur. When your thyroid over-performs it causes your pulse to race, your bowel movements to be accelerated, sudden weight loss, as well as excited and aggressive mood swings. When it under-performs it can cause your pulse to slow down, weight gain, constipation and depression. A thyroidectomy is the usual medical procedure undergone to treat disorders relating to your thyroid. These range from minor diseases to cancers and how much of the thyroid is removed totally depends on the reason for the thyroidectomy. If a partial thyroidectomy is performed then only part of the thyroid gland is removed and it may still be able to function normally post-surgery. If a total thyroidectomy is performed and the entire gland is removed, patients inevitably need daily treatment with thyroid hormone replacement therapy to counteract the removal of the thyroid gland. Find out more about thyroidectomies on our website and/or contact us today for more information on how we can facilitate a range of medical procedures for you right here in France.

Thyroidectomy

03/06/2014

THYROIDECTOMY What is a Thyroidectomy? The thyroid is an endocrine gland which produces hormones controlling different bodies’ functions. To some extent it can be compared to the body’s general thermostat: When over performing, it triggers pulse acceleration, bowel movement acceleration, weight loss, excitation and aggressiveness. When Under performing, it triggers pulse slowdown, constipation, weight increase, Memory troubles and dépression signs. The thyroid gland can suffer from minor disease or cancer. Up to 10% of people may suffer from a minor thyroid disease (goitre, nodule, hypo or hyperthyroidism) Cancer represents 10 to 12 % of thyroid’s tumour, which explains complete screening prior of deciding for a surgery. Prognostic is very good in more than 90% of cases. The surgery called “thyroidectomy” is performed under general anaesthesia. It consists in removing part or all of the thyroid gland. Incision is done in the neck’s fold to hide the scar as much as possible. If a cancer is suspected, an anatomo-pathologist doctor present during surgery will perform an immediate preliminary analysis of the removed nodule which will help the surgeon decide if a total gland removal is required, reducing the risk to have to perform another surgery later on. If it only is a toxic nodule (e.g. which over produces hormones), only half of thyroid removal will be necessary.
