Faking symptoms? Too lazy to work? No! Functional neurological symptoms, such as tremors, limb weakness or numbness, facial functional disorders and tics, gait disorders, blackouts, dizziness and many others that seem to have no physical cause, are the second most common reason for outpatient neurology consultation (after headaches). These symptoms have been described in the medical literature as the 17th …
There is no such thing as an illness that is “all in your head”. Just because the current level of medical science can’t understand what’s happening in the brain-body connection doesn’t mean your symptoms don’t exist. Research is beginning to find more and more ways that “mental” illnesses are caused by “physical” stimuli, and vice versa. This insight leads to …
Bipolar disorder is a chronic disease that can present lifelong challenges. However, remission rates and even complete recovery can and have been seen. Finding the factors associated with recovery from bipolar disorder can give us all hope, and also provide health care workers with specific strategies to enhance the possibilities of recovery. A recent Canadian study using data from the …
Doing nothing? Daydreaming? Your brain is still working away Neuroscientists have discovered that brain activity occurs in “networks”: a coherent interaction of different brain regions. The networks are activated harmoniously or cooperatively, depending on what you are doing. One network, connecting several different brain regions, becomes activated when we are at rest, doing “nothing” or just daydreaming. This has been …
Patients in recovery from major depressive episodes may need help learning to process positive information and stimuli. Researchers found that people with a history of major depressive disorder spend more time processing negative information than healthy controls, and they may have less control over which information they process. This negative bias suggests that people recovering from depression may need to …
“I really adjusted fast, it was miraculous…” Patients who travel are familiar with warnings and advice we give about the potential for moods to get unbalanced or even out of control as a result of jet lag and time changes on international flights. Recently, Jason, who was making a 15-hour time change for his honeymoon, reported back on the helpfulness …
Is it true that people with mental illness, particularly mood disorders, are more creative? Or do creative people more often develop mental illness? Does the medication given for mood swings dampen creativity? Are there different types of creativity that manifest themselves during heightened, depressed and normal moods? What is creativity, anyway? These are hotly debated questions but clear guidance is …
Inflammation in the body may be associated with depression, but until recently, the evidence was confusing. Now, a study has looked at symptoms of depression separately, and has found that certain symptoms associated with depression are also correlated with systemic inflammation. Common symptoms of depression that are classified as physical: “changes in appetite”, “felt everything was an effort”, “loss of …
Bipolar and sleep disruption People with bipolar can have as much sleep disruption in a week that those without mood disorders will experience in a much longer time frame. Mood swings can cause major changes in sleep patterns and disrupted sleep makes it much more difficult to maintain mood stability. That’s why MoodSurfing offers so many resources about sleep and …
Oxytocin is a neurohormone that is produced in the human brain and helps us form loving connections: mother-child bonds as well as the connections between romantic partners. When we are with a person who stimulates our oxytocin-producing neurological system, we feel warmed, supported, in a word: loved. However, making us feel loved doesn’t seem to be exactly the function of …
Seasonal Mood Changes Spring is coming, a season that some call “mania season”. Even those without mood disorders often feel a rush of energy and hopefulness as the days finally start to get longer, and the temperatures go up. Many of our bipolar patients find that their mood swings follow a predictable pattern: for the majority, “up” in the spring …
Low Serotonin – What do you need? Serotonin is a neurotransmitter and hormone that our bodies produce naturally and that is used by the brain to regulate and support several systems throughout the body. The body produces serotonin using building blocks synthesized from nutritional input. The amount of serotonin produced can vary depending on a number of circumstances, some of …
Three studies have recently been concluded, each of which looks at the effect of television watching habits on brain health, specifically gradual reductions in the amount of gray matter found in the aging brain. All three studies found that those who watched less television on average had less loss of brain volume in tests conducted after a period of several …
Does bipolar disorder cause problems with memory, attention focus, speed of thinking and cognition? Does depression cause dementia, or does it just feel like it? Are memory problems and cognition issues caused by the medications that control mood episodes? Is there anything one can do about troubles in thinking and memory related to mood issues? “Suddenly becoming demented” is a …
Do the trillions of microbes living in the human digestive system affect our mental health and affect – for better or worse – brain or mood disorders? As recently as seven years ago, the idea that gut bacteria played a role in mental health was considered “crazy”, but in the past few years, more and more research has shown possible …
I was reminded this past week about the importance of staying active during the winter, as well as some of the challenges people face during this COVID-19 winter Why is this Hard? Our brains are somewhat poorly adapted to modern life. Our distant ancestors would go into hibernation mode during the winter. Food was not as plentiful, and going outdoors …
Depression, particularly recurrent depression, has pretty significant effects on how we perceive the world and how well we make plans for the future. In an article published in Biological Psychiatry in March 2020, Tobias Kube and co-authors develop a model of how depression affects critical cognitive processes that expands and extends the traditional model of cognitive changes associated with depression …
Lack of sleep is associated with weight gain, but why is this? Is it just because sleep deprivation makes us grumpy and we “self-medicate” with food? People who get poor quality sleep, or not enough sleep, start craving high carbohydrate and high fat foods that are more likely to cause weight gain. And sleep deprivation makes us less likely to …
Can you change your brain? Recent research in the field of “neuroplasticity” suggests that the human brain continues to change and adapt throughout life. Furthermore, there is clear evidence that an individual can affect the changes to their own brain structure by how they pay attention to stimuli around them. The implication of this research is that, for example, a …
The human brain is still a mystery in many ways, with much of our brain function difficult or impossible to study under most conditions. What causes worsening moods and why do some people struggle with anxiety and depression while others do not? A recent study at UC San Francisco took advantage of work being done for patients with epilepsy who …
