High Blood Sugar May Affect Memory

A recent article from USA Today suggests that people with Type 2 Diabetes have a harder time performing memory tasks. The study was able to find a correlation between chronic high glucose levels and poor memory in the participants, among which the mean age was 63 (but remember that correlation does not always imply causation – this is just one study that has been done). It was also found that higher glucose levels had reduced volumes of their hippocampus (the part of the brain heavily involved in memory) compared to the participants with normal glucose levels. In general, high levels of glucose have a negative impact on the brain if not regulated properly. People with Type 2 diabetes are also at a higher risk of dementia, another cognitive defect. If someone has diabetes, it is important for them to improve their body’s usage of insulin to keep their glucose levels under control; this can be done through exercise and physical activity.

“Burdened” by Guilt….Literally?

While guilt is useful in regulating moral behaviour, it can bring with it unwanted feelings of tension and regret. A recent study by Princeton researchers Martin Day and Ramona Bobocel has shown that unethical, guilt-inducing memories may affect specific physical sensations in the body.

Participants were told to recall personal unethical acts, while other participants were told to recall ethical acts, unethical acts of others, or no recall at all. The researchers found that participants who recalled personal unethical acts reported increases in their subjective body weight in comparison to the controls. Additional trials involving performing physical behaviours such as carrying objects, also showed striking results. Participants who recalled personal unethical acts perceived physical behaviours to require more effort compared to the control participants.

The effects of the psychological feelings of guilt on the subjective sensations of the body is an area of study which requires further research, in order to add more insight into understanding the feelings of guilt. For now, take heed, the next time someone says they feel “burdened” with guilt, they may just mean it literally.

Underestimating Mental Health Problems in Canada

An article in the Huffington Post titled “Why Mental Illness Goes Much Farther Than Research Tells Us” critiques the 2012 Canadian Community Health Survey on Mental Health, specifically stating its exclusionary sample is creating a rather convenient picture of mental health in Canada.

As any science student and professional knows, having a representative sample is, you know, kind of important. One of the article’s complaints about this particular sample is it leaves out groups that are particularly prone to more mental health issues, such as those living on reserves and the institutionalized. With this in mind, the results can really only be taken at face value, or at least only generalized to the rest of society — not exactly great validity.

My question is, why might have the Canadian government decided to exclude these particular groups from the sample? Were they simply wishing to get a more realistic view of the “average” Canadian? If this were the case, I would question why we need to ignore vulnerable groups, as they are part of the social ecosystem; excluding these people seems like a blatant disregard of their roles in Canadian society.

Research methods aside, what are the consequences of these statistics? My gut feeling makes me wonder if this is the government’s way of saying, “Hey, look how well we’re doing!” when we’re really not doing that well. If the results favour lower levels of mental health issues, then solutions for these problems may not be as urgent. The smaller the problem, the easier it is to sweep under the carpet.

Anyone working in the mental health field has some sort of awareness about the lack of funding and resources mental health programs receive. In my own experience volunteering in community housing for those with severe mental health issues, I know only too well the poor living conditions and lack of social support these people receive.

The ultimate question: How can we make Canada more mentally healthy?

Caffeine Consumption May Slow Brain Development

In today’s busy world, it’s difficult for most people to be alert and productive unless they have their morning cup of coffee. Various negative effects of excessive caffeine consumption are widely known, such as dehydration and withdrawal symptoms. However, a recent study by the Swiss National Science Foundation has revealed further implications.

The study involved prepubescent mice that consumed the equivalent of 3-4 cups of coffee in caffeine per day. This resulted in reduced deep sleep as well as delayed maturation of the brain. Researchers say that teenagers and young children who consume caffeine could similarly have slowed brain development as a result. Additionally, as caffeine increases heart rate, it may aggravate cardiovascular problems in addition to affecting neuronal development.

While most teenagers may not drink as much coffee as their parents, caffeine may find it’s way into their diet through other forms, such as soft drinks, energy drinks, and tea. It may be unreasonable to ask people to stop drinking soda and coffee altogether; the important thing is to limit your consumption to a reasonable amount your body can tolerate. For children aged 4-6, the maximum recommended intake is 45 milligrams per day. While no such maximum has been recommended for adults, most adults can tolerate about 400 milligrams per day.

Anxiety’s Duality

Students often vocalize the comment, “I’m feeling anxious today”. With mounting pressures to maintain a certain GPA for graduate programs or scholarships, while often balancing work or volunteer experience, it’s no wonder that anxiety is a growing concern on university campuses. It is important, however, to understand that although many students may “feel anxious” throughout their university career, it certainly does not designate them as having an anxiety disorder. In fact, having anxiety is a perfectly normal human condition. When you feel anxious before a midterm or a job interview and you are experiencing physical symptoms such as ‘butterflies in your stomach’ and chest palpitations, your body and brain are motivated to perform at your best. It may be helpful to re-frame those unpleasant symptoms as evidence for your determination to excel.

When anxiety does become a problem, one is plagued with physical symptoms and recurring thoughts of worry when there is no immediate danger. The physical symptoms can be so severe that individuals will choose not to be in public places, in fear that an episode or ‘panic attack’ will occur. Thankfully, there are professionals who are committed to supporting individuals who are suffering from an anxiety disorder. The anxiety B.C. website is a wonderful resource for learning more about anxiety and the various disorders within this, along with helpful strategies to combat the physical discomfort and unrealistic thoughts. They even have an app called ‘MindShift,’ which allows individuals to assess their level of anxiety, make an action plan for specific worries, and engage in ‘mind-chilling’ activities to improve their mental health. Anxiety is an adaptive trait of all humans but it was not designed to stop us from achieving our personal goals and engaging with friends and family. Anxiety BC acknowledges that some are struggling with constant worry, but it should never be in silence.
