Serotonin Serotonin may be the most well-known neurotransmitter. Low levels of serotonin are linked to both anxiety and depression. Like most neurotransmitters, low or unbalanced serotonin levels can occur genetically/naturally, and can also be created by your emotions.
But researchers don't know exactly what causes anxiety disorders. They suspect a combination of factors plays a role: Chemical imbalance: Severe or long-lasting stress can change the chemical balance that controls your mood. Experiencing a lot of stress over a long period can lead to an anxiety disorder.
To stop the excitable neurons getting too carried away and causing trouble, the brain has a neurochemical, GABA, which is the brain's 'calm down' chemical. GABA plays a key role in the way the body responds to stress.
Causes of Anxiety Disorders
Chronic, heavy stress. Exposure to major traumatic events. Health issues such as diabetes and heart diseases. Use of certain medications for serious health issues.
Anxiety happens when a part of the brain, the amygdala, senses trouble. When it senses threat, real or imagined, it surges the body with hormones (including cortisol, the stress hormone) and adrenaline to make the body strong, fast and powerful.
Serotonin is a crucial chemical for increasing mood and decreasing anxiety. Researchers have found a clear connection between low serotonin levels and increases in depression, anxiety, and other mental health challenges.
Difficult experiences in childhood, adolescence or adulthood are a common trigger for anxiety problems. Going through stress and trauma when you're very young is likely to have a particularly big impact. Experiences which can trigger anxiety problems include things like: physical or emotional abuse.
Anxiety may be caused by a mental condition, a physical condition, the effects of drugs, stressful life events, or a combination of these.
A big event or a buildup of smaller stressful life situations may trigger excessive anxiety — for example, a death in the family, work stress or ongoing worry about finances. Personality. People with certain personality types are more prone to anxiety disorders than others are.
Endorphins are hormones that are released when your body feels pain or stress. They are produced in your brain and act as messengers in your body. Endorphins are produced to help relieve pain, reduce stress and improve mood.
Cortisol is the main villain who creates unhealthy overthinking and is released in the hypothalamus – a region very near to the centre of your brain.
GABA is known for producing a calming effect. It's thought to play a major role in controlling anxiety, stress and fear. Decreased GABA levels are associated with several neurological and mental health conditions, as well as other medical conditions.
Anxiety disorders are the most common of mental disorders and affect nearly 30% of adults at some point in their lives. But anxiety disorders are treatable and a number of effective treatments are available. Treatment helps most people lead normal productive lives.
Research has indicated that individuals with high emotional reactivity (high neuroticism) and introverted tendencies (low extroversion) are more likely to experience anxiety than other personality types [101].
The NIH reports that generalized anxiety affects approximately 2.7 percent of American adults, with women experiencing the disorder at a higher rate (3.4 percent) versus men (1.9 percent). Around 5.7 percent of adults will experience anxiety at some point in life.
Certain drugs and substances such as caffeine, alcohol, nicotine, NutraSweet, antidepressants, and some cholesterol-lowering medications deplete serotonin and other neurotransmitter levels. Hormone changes cause low levels of serotonin and neurotransmitter imbalances.
Vitamins B9 and B12 are both thought to treat symptoms of anxiety. Folic acid has many uses in the body, and B9 deficiency has been linked to higher levels of anxiety and depression.
Anxiety Therapy is one way to rewire the brain. It helps you build new neural pathways that are healthy and help control anxiety symptoms. Mindfulness is another way to rewire the anxious brain. Mindfulness helps retrain the brain through mindfulness meditation, which will effectively help with anxiety.
You can heal and retrain this entrenched system in your brain by giving the limbic system new information. Ideally, you would do this with the help of a counselor, but if the symptoms are relatively mild, you may try this on your own.
