Carbon Dioxide: A Physical Trigger For Panic Attacks For Some

Stop your Panic Attacks Today and the story of Bob the Spider

In severe anxiety or panic disorders, people often feel like they are short of breath or suffocating. Interestingly, people with panic disorder also have a heightened sensitivity to carbon dioxide. Most people, when inhaling higher percentages of carbon dioxide dont have a response, but in people with panic disorder, inhaling a higher than normal amount of CO2 can actually trigger a panic attack.

Increasing the CO2 levels in the blood increases the acidity . Researchers theorize a chemical sensor in the amygdala is involved in the detection of pH levels. In mouse studies, inhaled CO2 drops the pH in the amygdala and causes fear behaviors. This is mediated by the acid-sensing ion channel-1a subunit .

What Life Events Or Environmental Factors Can Contribute To Anxiety

Can anxiety be genetic? Yes, but scientists know environmental factors and life experiences are the main contributing factors.

Every experience impacts a person differently. What research has shown is that certain factors do increase the likelihood of triggering an anxiety disorder.

Some of these factors include:

  • Family violence
  • Three or more traumatic childhood experiences
  • Illness

Genetic Epidemiology Of Panic Disorder

For a long time, family and twin studies have suggested there are genetic influences on PD. Linkage analyses and association studies have become predominant, making up for several limitations of family and twin studies. However, they are still not sufficient for reaching a clear conclusion regarding PD’s genetic basis.

Panic Disorder With Agoraphobia

Agoraphobia was traditionally thought to involve a fear of public places and open spaces. However, it is now believed that agoraphobia develops as a complication of panic attacks and panic disorder. Although it can develop at any point, agoraphobia usually appears within a year of your first recurrent panic attacks.

If youre agoraphobic, youre afraid of having a panic attack in a situation where escape would be difficult or embarrassing. You may also be afraid of having a panic attack where you wouldnt be able to get help. Because of these fears, you start avoiding more and more situations.

For example, you may begin to avoid:

  • Crowded places such as shopping malls or sports arenas.
  • Cars, airplanes, subways, and other forms of travel.
  • Social gatherings, restaurants, or other situations where it would be embarrassing to have a panic attack.
  • Physical exercise in case it triggers panic.
  • Certain food or drinks that could provoke panic, such as alcohol, caffeine, sugar, or specific medications.
  • Going anywhere without the company of someone who makes you feel safe. In more severe cases, you might only feel safe at home.

Can I Take Medications To Get Rid Of Anxiety

Behavioral Inhibition In Childhood

Do you know a toddler or young child who always becomes extremely upset when confronted with a new situation or unfamiliar person? When faced with these types of situations does the child cry, withdraw, or seek the comfort of a parent?

This type of behavior in toddlers and young children is known as behavioral inhibition. Children who show behavioral inhibition as a toddler are at greater risk for developing SAD later in life.

Because this temperament shows up at such a young age, it is likely an inborn characteristic and the result of biological factors.

If you are concerned that your child is excessively withdrawn or fearful in new situations, it may be helpful to discuss your worries with a professional. Since we know that behaviorally inhibited toddlers are more likely to become socially anxious children and socially phobic adults, any kind of early intervention may help prevent more serious problems later in life.

Signs And Symptoms Of Panic Disorder

While many people experience just one or two panic attacks without further episodes or complicationsand theres little reason to worry if thats yousome people go on to develop panic disorder. Panic disorder is characterized by repeated panic attacks, combined with major changes in behavior or persistent anxiety over having further attacks.

You may be suffering from panic disorder if you:

  • Experience frequent, unexpected panic attacks that arent tied to a specific situation
  • Worry a lot about having another panic attack
  • Are behaving differently because of the panic attacks, such as avoiding places where youve previously panicked

While a single panic attack may only last a few minutes, the effects of the experience can leave a lasting imprint. If you have panic disorder, the recurrent panic attacks take an emotional toll. The memory of the intense fear and terror that you felt during the attacks can negatively impact your self-confidence and cause serious disruption to your everyday life. Eventually, this leads to the following panic disorder symptoms:

Anticipatory anxiety Instead of feeling relaxed and like your normal self in between panic attacks, you feel anxious and tense. This anxiety stems from a fear of having future panic attacks. This fear of fear is present most of the time, and can be extremely disabling.

Understanding The Causes Of Social Anxiety Disorder

Steven Gans, MD is board-certified in psychiatry and is an active supervisor, teacher, and mentor at Massachusetts General Hospital.

If you have been diagnosed with social anxiety disorder , you may wonder what caused you to develop the illness. Rather than there being a single causative factor, it is likely a complex interplay of variables that result in the disorder.

Does Anxiety Run In The Family

Is Anxiety Hereditary / Genetic Or Learned?

Is anxiety genetic? It is normal to feel anxious every once in a while. You can feel nervous when you have a problem, before a test or when faced with a hard decision that needs to be made.

There are a variety anxiety disorders. Because they are mental disorders, the distress that comes with the condition can make it impossible for you to carry on with life normally. People who suffer from anxiety are constantly in fear and always worrying. This can be very overwhelming and disabling. Even so, one can get treatment for anxiety, which can help to suppress the symptoms and enable them to lead a healthy life.

If Anxiety Or Depression Runs In Your Family

Age may be a clue about whether your family might have a genetic link to anxiety or depression. If one of these conditions shows up in someone before the age of 20, their family members are more likely to, as well. In most cases, the younger the person is when they get anxiety or depression, the more likely it is to be hereditary.

Anxiety and depression can still be genetic if they show up in your older family members. But often, new conditions in people that are over the age of 20 are linked to painful or stressful life events.

Youâre more likely to inherit a tendency for anxiety or depression if a close family member has it, instead of a more distant relative. If you have a twin, parent, or sibling who has anxiety or depression, youâre more likely to get it because youâre closely related to them.

What Causes Panic Attacks

Experts dont know why some people experience panic attacks or develop panic disorder. The brain and nervous system play key roles in how you perceive and handle fear and anxiety. Your risk of having panic attacks increases if you have:

  • Family history:Anxiety disorders, including panic disorders, often run in families. Experts arent sure why.
  • Mental health issues: People who have anxiety disorders, depression or other mental illness are more prone to panic attacks.
  • Substance abuse problems:Alcoholism and drug addiction can increase the risk of panic attacks.

What If Panic Disorders Run In Your Family

Even though panic disorders are influenced by your genetics, just because you have a relative with the disorder doesnt mean youll get it yourself. Environmental factors can play a protective role. For instance, developing healthy ways to cope with stress can help reduce your risk of experiencing anxiety. However, a family history of panic disorders may mean you are at a higher risk of developing one, too. Still, knowing your family history and risk factors can lead you to get help as soon as you need it.

Know Your Health: Is Anxiety Genetic

Symptoms of Panic Attacks.

Many people experience anxiety during their lifetime. However, anxiety is not normal if it takes over your life.

A genetic predisposition for anxiety can trigger an over-the-top response to a low-key event. There are many risk factors for anxiety disorders including genetics, personality, brain chemistry, and external influences.

Adora2a And Adenosine: Jittery And Startled

One gene linked with anxiety in multiple studies is the ADORA2A gene. ADORA2A codes for the adenosine 2A receptor, which is important in the way that the brain works.

Adenosine, an important biological compound, is made up of an adenine molecule and a d-ribose sugar molecule. Its found in every cell in the body. Adenine is a nucleotide . D-ribose is the sugar that makes up part of the DNA molecule .

Adenosine also may sound familiar because it is part of the ATP molecule .

In the brain, adenosine is important in the way that the neurons work. It helps to fine-tune the way that neurons communicate, and it also helps to balance the inhibitory and excitatory neurons.

Adenosine levels in the brain increase over the course of the day. This higher level of adenosine is what causes you to feel sleepy at night called the homeostatic sleep drive.

Caffeine works to make you feel awake by blocking the adenosine receptor so that the adenosine cant attach to it. Genetic variants in the adenosine receptor alter peoples response to caffeine.

Animal studies are great for showing exactly how a gene works. Mice have greatly increased anxiety when researchers knock down the ADORA2A gene expression. They also had an increased heart rate, increased platelet aggregation, and altered pain response, because adenosine is important in a lot of different functions in the body.

Dominant Vs Recessive Genes

While your dominant genes can’t help but affect you, you may also have received recessive genes from your parents that would have predisposed you towards anxiety had they been dominant.

Recessive genes are the reason why two brown eyes people may have a green-eyed baby: one of the brown-eyed people had a green-eyed parent or grandparent and carried the recessive gene for green eyes which showed up as dominant again in the baby.

They are also the reason why, even if neither of your parents necessarily had an anxiety disorder, one of them may have carried a recessive gene that you received as a dominant gene which predisposed you to anxiety.

If you received the gene as a recessive gene and not as a dominant gene, you may pass on a predisposition towards anxiety that you don’t even have yourself to your offspring. Fortunately, anxiety disorders are both manageable and treatable, and may even have some advantages along with their disadvantages.

What Does It Mean For Something To Be Genetic Or Hereditary

When a disease is hereditary, it means you can be born with a chance of developing it. That chance was given to you by your biological mother, father, or both. Sometimes this means your mother or father had the disease. Sometimes they might have had genes for it, but never actually got sick.

Genes are part of our DNA. They are inside every single cell in our bodies and cant be changed with medication or treatments. What can change is whether or not a gene becomes activated.

When you inherit a disease like anxiety, a variety of factors like how stressful your life is will determine if it is going to be a problem.

Considerations In The Genetic Studies Of Panic Disorder

Panic Disorder

Although studies have achieved tremendous results regarding a genetic basis for PD so far, researchers have not reached a clear conclusion. Linkage analyses have suggested that several chromosomal regions associate with PD, but they have not yet identified a major gene for PD. Here, we discuss several limitations of genetic studies of PD, including considerations of current diagnostic problems with the DSM-IV criteria for PD.

Genetic Causes Of Panic Disorder

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.

  • Study Details

This study will try to identify genes that increase the risk of developing panic disorder-an anxiety disorder characterized by recurrent unexpected panic attacks-and that contribute to the abnormalities associated with it. It will compare reactions in patients with panic disorder and in normal volunteers to caffeine, a compound that can induce anxiety, and to placebo, an inactive substance. Caffeine is believed to induce anxiety by blocking proteins called adenosine receptors on the surface of nerve cells in the brain. One study found that people with a specific adenosine receptor gene called 1976T/T had greater anxiety in response to caffeine challenge than did people with other adenosine receptor gene groups. There is also evidence that people with the 1976T/T genotype are more vulnerable to having panic disorder.

Serotonin: Anxiety And Depression

Serotonin is a neurotransmitter involved in mood. This pathway is a common target of antidepressant and antianxiety medications known as SSRIs. Serotonin is also important in gut motility and in sleep .

Researchers still have a lot of questions about how serotonin works in anxiety. The key may be that serotonin acts differently in situations of fear or panic, compared to situations that cause general anxiety.

Several genetic variants in serotonin-related pathways have been linked to PTSD, which is classified as an anxiety disorder.

How Does Stress Affect Anxiety

Social Anxiety Disorder: More Than Just Being Shy ...

As mentioned above, in addition to genetics, the environment you live in affects whether or not you will have anxiety. For example, scientific research shows that experiencing a childhood trauma like abuse or a disrupted family makes you more likely to develop anxiety later. The timing of life stress can also be important. Teenagers seem to be particularly sensitive to interpersonal stresses, like rejection or bullying.

The new field of epigenetics takes the powerful connection between genetics and environment one step further. Research in this area shows that stress during pregnancy or even before pregnancy can affect whether or not a child develops anxiety later. Scientists believe this happens because some genes can be programmed to turn on or off even before they are passed down from parent to child.

Anxiety can also be learned. Children learn how to handle situations by watching how the adults around them behave. If their parents often respond to events with anxiety, children may learn to model that behavior. For scientists studying anxiety, this pattern can be very difficult to separate from genetics.

Tips To Avoid Depression And Anxiety

If youâre at risk for depression or anxiety, youâll want to do everything you can to prevent them, just as you would with any other serious medical condition:

Consider starting counseling proactively. Finding a therapist before thereâs a problem can help you learn skills to manage situations that could trigger anxiety or depression. Tell them about your familyâs history of these or other conditions. If you want a referral, ask your doctor.

Brush up on key nutrients. A healthy diet can help support your body and brain. Make sure youâre getting enough of these nutrients:

  • Omega-3 fatty acids. Theyâre in some fish , flaxseed, and pumpkin seeds. These fats are needed for brain health.
  • B vitamins. People with low B vitamin levels are more likely to develop depression. Foods that contain B vitamins include green vegetables, beans, lentils, whole grains, seeds, nuts, fruits, meat, eggs, and other animal products.
  • Vitamin D. Low levels of vitamin D are linked to depression, but itâs not clear if they actually cause it. Your body makes vitamin D if you get some time in the sun, or you can get it from fortified foods or supplements.

Limit added sugars. Foods that naturally have sugar in them, like fruit, will keep your bodyâs energy at a more constant level.

Make exercise a habit. Research shows it can help with mild to moderate depression. And itâs a great way to release stress, boost your mood and energy level, and take care of your physical health.
