How a good night’s sleep can protect against fear !

By

New research has found that better-quality sleep is connected with reduced activity in brain regions implicated in fear learning. Thus, time spent in rapid eye movement sleep could be a good indicator of susceptibility to post-traumatic stress disorder.

Sleep disturbances are linked with a poorer quality of life overall, and they are often associated with a range of mental health issues, including depression and anxiety.

Other conditions, such as epilepsy, have also been associated with sleeplessness, and a recent study covered by Medical News Today even suggests that there may be a causal relationship between sleep disturbances and ADHD.

Dr. Itamar Lerner, Shira Lupkin, and other researchers from Rutgers University in Newark, NJ, have now conducted a study indicating that better-quality sleep is linked with dampened brain activity in regions tied to fear learning.

The process of fear learning is the mechanism through which we attempt to predict exposure to threatening situations so that we react appropriately to preserve our safety.

Menopause may trigger Alzheimer’s disease !

By

A new study highlights the metabolic changes that occur in the brains of menopausal and perimenopausal women, suggesting that a loss of estrogen could make these women vulnerable to developing Alzheimer’s disease.

The study was carried out by researchers at Weill Cornell Medicine – the biomedical research unit and medical school of Cornell University – in New York City, NY, in collaboration with scientists at the University of Arizona Health Sciences in Tucson.

Dr. Lisa Mosconi, from Weill Cornell Medicine, is the lead author of the study, and the findings were published in the journal PLoS One.

As Dr. Mosconi and her colleagues explain, after old age, being female is the second most major risk factor for developing Alzheimer’s disease.

In fact, two thirds of those with Alzheimer’s disease in the United States are women, according to 2017 estimates.

Although the mechanisms responsible for this increased risk are not yet known, previous research has hinted at the transition to menopause as a potential key.

As the authors explain, this transition also involves neurological and metabolical changes. So, Dr. Mosconi and team decided to investigate these transformations

How do your allergies develop?

By

Worldwide, allergies are on the rise at an alarming rate. How do our bodies mistake otherwise harmless substances for potential dangers and cause the unpleasant, and sometimes even fatal, symptoms of allergy?

From the mother anxiously watching for signs of wheezing the first time her child eats peanut butter to the retiree’s sudden reaction to shellfish, allergies can strike at any point during our lives.

Hay fever affects 400 million individuals globally, with asthma affecting 300 million, food allergies between 200 and 250 million, and drug allergies affecting around 10 percent of the world’s population.

The World Allergy Organization (WAO) warn that “the prevalence of allergic diseases worldwide is rising dramatically in both developed and developing countries.”

Allergens, or molecules with the potential to cause allergy, are everywhere in our environment. They come in the form of tree pollen, food, mold, dust mites, snake or insect venom, and animals, such as cats, dogs, and cockroaches.

When the body mistakes one of these substances as a threat and reacts with an immune response, we develop an allergy. Nobody is born with allergies. Instead, the 50 million people in the United States who suffer from allergies developed these only once their immune systems came into contact with the culprit.

But how do our bodies mistake a friend for a foe? And what causes the symptoms that many are so familiar with?

Meditation may help to lower heart disease risk !

By

A new scientific statement from the American Heart Association has concluded that meditation may help to lower heart disease risk, but that adopting a heart-healthy lifestyle and adhering to medical advice should remain the primary prevention strategies.

The conclusion, which was recently published in the Journal of the American Heart Association, comes from a comprehensive review of existing studies investigating the effects of meditation on risk factors for heart disease.

Heart disease is the number one killer in the United States, responsible for around 610,000 deathsin the country every year.

Heart disease refers to a number of conditions that impact the functioning of the heart, including coronary heart disease, irregular heartbeat, or arrhythmia, and heart attack.

Making lifestyle changes – such as quitting smoking, following a healthful diet, and exercising regularly – is considered key for lowering the risk of heart disease.

Coping with panic disorder !

By

Do you experience sudden attacks of anxiety, fear, and panic? Perhaps your heart races, you feel unable to breathe or think properly, and you sweat. Do these attacks have no obvious trigger? Here are some of the best ways to cope with panic disorder to improve your quality of life.

Panic disorder affects 2 to 3 percent of people in the United States per year, and it is twice as likely to occur in women than in men. Individuals with panic disorder tend to have spontaneous panic attacks, and they therefore become preoccupied with the fear that they may happen again, at any time.

The condition can interfere with many aspects of the person’s life, causing them to avoid work or school and avoid situations wherein they fear a panic attack may occur.

Many people with panic disorder are embarrassed or afraid to tell anyone about what they experience, instead distancing themselves from family and friends who could be supportive.

Panic disorder is highly responsive to treatment. Building a toolbox of self-help strategies can be effective in helping you to manage your symptoms without living in fear. Here are Medical News Today‘s tips for coping with panic disorder.
