Anxiety – Causes, Symptoms and Treatments and More
What is anxiety?
Anxiety is a feeling of fear, dread, and uneasiness. It might cause you to sweat, feel restless and tense, and have a rapid heartbeat. It can be a normal reaction to stress. For example, you might feel anxious when faced with a difficult problem at work, before taking a test, or before making an important decision. It can help you to cope. The anxiety may give you a boost of energy or help you focus. But for people with anxiety disorders, the fear is not temporary and can be overwhelming.
What are anxiety disorders?
Anxiety disorders are conditions in which you have anxiety that does not go away and can get worse over time. The symptoms can interfere with daily activities such as job performance, schoolwork, and relationships.
What are the types of anxiety disorders?
There are several types of anxiety disorders, including:
Generalized anxiety disorder (GAD).People with GAD worry about ordinary issues such as health, money, work, and family. But their worries are excessive, and they have them almost every day for at least 6 months.
Panic disorder. People with panic disorder have panic attacks. These are sudden, repeated periods of intense fear when there is no danger. The attacks come on quickly and can last several minutes or more.
Phobias. People with phobias have an intense fear of something that poses little or no actual danger. Their fear may be about spiders, flying, going to crowded places, or being in social situations (known as social anxiety).
What causes anxiety disorders?
The cause of anxiety is unknown. Factors such as genetics, brain biology and chemistry, stress, and your environment may play a role.
Who is at risk for anxiety disorders?
The risk factors for the different types of anxiety disorders can vary. For example, GAD and phobias are more common in women, but social anxiety affects men and women equally. There are some general risk factors for all types of anxiety disorders, including:
Certain personality traits, such as being shy or withdrawn when you are in new situations or meeting new people
Traumatic events in early childhood or adulthood
Family history of anxiety or other mental disorders
Some physical health conditions, such as thyroid problems or arrhythmia
What are the symptoms of anxiety disorders?
The different types of anxiety disorders can have different symptoms. But they all have a combination of:
Anxious thoughts or beliefs that are hard to control. They make you feel restless and tense and interfere with your daily life. They do not go away and can get worse over time.
Physical symptoms, such as a pounding or rapid heartbeat, unexplained aches and pains, dizziness, and shortness of breath
Changes in behavior, such as avoiding everyday activities you used to do
Using caffeine, other substances, and certain medicines can make your symptoms worse.
How are anxiety disorders diagnosed?
To diagnose anxiety disorders, your health care provider will ask about your symptoms and medical history. You may also have a physical exam and lab tests to make sure that a different health problem is not the cause of your symptoms.
If you don’t have another health problem, you will get a psychological evaluation. Your provider may do it, or you may be referred to a mental health professional to get one.
What are the treatments for anxiety disorders?
The main treatments for anxiety disorders are psychotherapy (talk therapy), medicines, or both:
Cognitive behavioral therapy (CBT) is a type of psychotherapy that is often used to treat anxiety disorders. CBT teaches you different ways of thinking and behaving. It can help you change how you react to the things that cause you to feel fear and anxiety. It may include exposure therapy. This focuses on having you confront your fears so that you will be able to do the things that you had been avoiding.
Medicines to treat anxiety disorders include anti-anxiety medicines and certain antidepressants. Some types of medicines may work better for specific types of anxiety disorders. You should work closely with your health care provider to identify which medicine is best for you. You may need to try more than one medicine before you can find the right one.

Tension Headaches | Triggers, Risk Factors, Signs & Symptoms, Types, Diagnosis, Treatment
Tension Headaches (also known as stress headaches and tension-type headaches) are very common headaches that lead to mild-moderate bilateral head pain. Tension Headaches can be triggered by a variety of factors including sleep deprivation, dehydration and stress. Tension Headaches differ from migraine headaches in many ways including that tension headaches are bilateral, do not have associated nausea/vomiting and do not have a prodrome. In this lesson, we discuss all the triggers, risk factors, signs and symptoms, how they are diagnosed and how they are treated.

Five million people in the U.S experience at least one migraine attack per month. Dr. Patricia Feito, Family Medicine Physician at Baptist Health Primary Care, says the biggest trigger is stress. “We can’t deny that obesity and being overweight are conditions that trigger migraines but stress is an utmost primary thing that we look at when we’re dealing with migraine triggers,” she explains.
She points out a migraine is a headache, it is an intense throbbing symptom that occurs in areas of the brain and it has a lot to do with electrical conduction of the brain attached to vascular circulation, causing either constriction or dilation.

Stress is the way our bodies and minds react to something which upsets our normal balance in life. Stress is how we feel and how our bodies react when we are fearful or anxious. Some level of stress has some upside to mind and body function to enable us to react in a positive way. Too much stress though, is both harmful to the body and our performance. How much is too much? Well, that depends… on you and how you respond.
It is essential to know how our brain responds to the stimuli which trigger an anxiety response so that you are equipped to deal appropriately with anxiety.
Let me highlight the key areas of your brain that are involved, and then I will explain what happens inside the brain.
The Thalamus is the central hub for sights and sounds. The thalamus breaks down incoming visual cues by size, shape and colour, and auditory cues by volume and dissonance, and then signals the cortex.
The cortex then gives raw sights and sounds meaning enabling you to be conscious of what you are seeing and hearing. And I’ll mention here that the prefrontal cortex is vital to turning off the anxiety response once the threat has passed.
The amygdala is the emotional core of the brain whose primary role is to trigger the fear response. Information passing through the amygdala is associated with an emotional significance.
The bed nucleus of the stria terminals is particularly interesting when we discuss anxiety. While the amygdala sets off an immediate burst of fear whilst the BNST perpetuates the fear response, causing longer term unease typical of anxiety.
The locus ceruleus receives signals from the amygdala and initiates the classic anxiety response: rapid heartbeat, increased blood pressure, sweating and pupil dilation.
The hippocampus is your memory centre storing raw information from the senses, along with emotional baggage attached to the data by the amygdala.
Now we know these key parts, what happens when we are anxious, stressed or fearful?
Anxiety, stress and, of course, fear are triggered primarily through your senses:
Sight and sound are first processed by the thalamus, filtering incoming cues and sent directly to the amygdala or the cortex.
Smells and touch go directly to the amygdala, bypassing the thalamus altogether. (This is why smells often evoke powerful memories or feelings).
Any cues from your incoming senses that are associated with a threat in the amygdala (real or not, current or not) are immediately processed to trigger the fear response. This is the expressway. It happens before you consciously feel the fear.
The hippothalmus and pituitary gland cause the adrenal glands to pump out high levels of the stress hormone coritsol. Too much short circuits the cells of the hippocampus making it difficult to organize the memory of a trauma or stressful experience. Memories lose context and become fragmented.
The body’s sympathetic nervous system shifts into overdrive causing the heart to beat faster, blood pressure to rise and the lungs hyperventilate. Perspiration increases and the skin’s nerve endings tingle, causing goosebumps.
Your senses become hyper-alert, freezing you momentarily as you drink in every detail. Adrenaline floods to the muscles preparing you to fight or run away.
The brain shifts focus away from digestion to focus on potential dangers. Sometimes causing evacuation of the digestive tract thorough urination, defecation or vomiting. Heck, if you are about to be eaten as someone else’s dinner why bother digesting your own?
Only after the fear response has been activated does the conscious mind kick in. Some sensory information, takes a more thoughtful route from the thalamus to the cortex. The cortex decides whether the sensory information warrants a fear response. If the fear is a genuine threat in space and time, the cortex signals the amygdala to continue being on alert.
Fear is a good, useful response essential to survival. However, anxiety is a fear of something that cannot be located in space and time.
Most often it is that indefinable something triggered initially by something real that you sense, that in itself is not threatening but it is associated with a fearful memory. And the bed nucleus of the stria terminals perpetuate the fear response. Anxiety is a real fear response for the individual feeling anxious. Anxiety can be debilitating for the sufferer.
Now that you know how anxiety happens in your brain, we can pay attention to how we can deliberately use our pre-frontal cortex to turn off an inappropriate anxiety response once a threat has passed.
