Panic disorder

Definitions & Key takeaways

Panic disorder is a type of anxiety disorder characterized by recurrent and unexpected panic attacks, which typically peak within the first 10-20 minutes though some might last hours. A panic attack is a sudden episode of intense fear or discomfort that can include physical symptoms such as heart palpitations, chest pain, sweating, shaking, and difficulty breathing.

Sometimes panic disorder gets so bad that the person stops engaging in activities that they think could trigger an attack, severely hampering their ability to function in day-to-day life.

The management may involve a combination of psychotherapy and medication. Cognitive-behavioral therapy is the most effective psychotherapy for panic disorder. Medications such as antidepressants and anti-anxiety medications can also be helpful.

. Panic disorder is a mental health condition characterized by recurrent and unexpected panic attacks, which are brief and sudden episodes of intense fear that peak within minutes.
This surge of fear is often accompanied by uncomfortable physical symptoms such as a racing heart, chest pain, shortness of breath, or sweating.
Now, imagine you're alone at home in the evening, watching a movie, just as things get tense, the door suddenly squeaks, you freeze, you hit the pause button, and before you can even think, your fear circuits in the brain kick in.
The almond shaped structure called the amygdala acts as an alarm system. It perceives the situation as threatening and screams, We are not safe!
Immediately it alerts the hypothalamus, which flips on the sympathetic nervous system. Your heart starts beating fast.
Your breathing speeds up. Your hands start shaking, and your mouth goes dry.
To make things worse, the locus ceruleus in the brain stem releases norepinephrine to flood the amygdala, acting like a turbo booster and pushing it into a state of hyperarousal.
Once the body enters this hyperaroused state, your internal sensor called the insula wakes up. It passes the information to the anterior cingulate cortex and dorsal medial prefrontal cortex, which act like supervisors deciding whether the situation is something you should worry about.
When these two recognize that there is no actual threat in the house, they stimulate the ventromedial prefrontal cortex.
The ventromedial prefrontal cortex works like a brake system. It uses the inhibitory neurotransmitter GABA to directly silence the amygdala.
At the same time, it stimulates the rai nuclei to release serotonin, which indirectly calms the amygdala even further. As this brake system kicks in, you gradually settle down and press play to continue the movie.
This fear circuit is absolutely normal. It's natural to experience some type of fear and anxiety when you're home alone at night watching a scary movie.
But imagine there's no scary movie, no door squeaking, and it's just you sitting in your living room watching TV and out of nowhere, the fear circuits in the brain kick in.
Complete horror. You have no idea what's going on, but you're terrified.
This is what we call a panic attack. That's exactly what happens in panic disorder because the normal brake system between the ventral medial prefrontal cortex and the amygdala is not working properly.
This happens because the amygdala has fewer gabiurgic and serotonin receptors available, so these calming neurotransmitters can't do their job properly.
On top of that, the locus ceruleus is working overtime and flooding it with norepinephrine. This combination keeps the amygdala stuck in a hyperactive state.
Next, the insula becomes disregulated and starts misinterpreting normal bodily sensations such as a faster heartbeat as signs of danger, further intensifying the fear.
Now there are several factors that can increase the risk of developing panic disorder. First, negative childhood experiences such as physical or sexual abuse.
Next, major life stressors such as divorce, the death of a loved one, or ongoing conflict at home or work. Temperament is another important factor.
Some people are naturally more sensitive to anxiety. This refers to the tendency to believe that normal symptoms of anxiety, like a racing heart or trembling, are dangerous.
Lastly, genetics play a role as well because panic disorder tends to run in families. Now moving on to clinical manifestations, these individuals typically feel fine and calm.
Then suddenly, without warning, a panic attack strikes. Panic attacks can even occur during sleep, in which case they're called nocturnal panic attacks.
The features of panic attacks can be subdivided into physical and psychological manifestations. Physical manifestations are driven by an overactive sympathetic nervous system.
The 10 classic physical symptoms include a racing or pounding heart, chest pain or tightness, shortness of breath, a choking sensation, nausea, trembling, sweating, chills or heat sensations, and dizziness.
Sometimes a person might report numbness or tingling, which is also known as parathesis, because these symptoms are so intense and abrupt, many individuals misinterpret them as signs of an emergency.
A racing heart might feel like a heart attack, while parenthesis may raise fears of stroke. On the other hand, the psychological manifestations arise from a hyperactive amygdala.
There are 3 main psychological symptoms. First, individuals might experience derealization where their surroundings feel unreal, almost like a dream, or they might experience depersonalization where they feel detached from their own body.
It's like they're playing a third person video game. Second, these sensations can trigger more frightening thoughts, such as fear of losing control or going crazy.
Finally, a person might experience a fear of dying, which further intensifies the panic attack. To diagnose panic disorder, the first step is confirming that the person is truly experiencing panic attacks.
A panic attack is a brief sudden episode of intense fear that peaks within minutes and includes at least 4 of the characteristic physical or psychological symptoms.
Once we establish that, the next question is frequency. A single panic attack isn't enough for the diagnosis.
The person must have recurrent, unexpected panic attacks, meaning they occur out of the blue without a clear trigger. But even that still isn't enough to meet the criteria for diagnosis.
At least one of these attacks must be followed by at least one month of additional problems. First, a person might develop persistent worry about having another panic attack.
Second, a person might begin changing their behavior to prevent future panic attacks. For example, they might stop exercising because sensations like a fast heartbeat or shortness of breath feel like the start of a panic attack.
Others might avoid elevators because they fear being trapped if one occurs. But before calling it a panic disorder, we must be sure that the panic attacks are not caused by something else.
This includes another medical condition like hyperthyroidism, substance use, or even medication. Only after ruling those out can we confidently make the diagnosis.
Next up is treatment, which can be subdivided into acute and long term management. During a panic attack, benzodiazepines can provide temporary relief.
These medications work by enhancing the effects of GABA in the brain, which help calm overactive fear circuits. Long term management involves both psychotherapy and medications.
Psychotherapy, such as cognitive behavioral therapy, helps individuals gradually manage their fears. For medications, the first line option involves selective serotonin reuptake inhibitors, which increase the amount of serotonin available in the brain, calming down overactive fear circuits.
Another option includes serotonin norepinephrine reuptake inhibitors, which boost availability of both serotonin and norepinephrine.
Finally, for individuals who do not respond to these medications, monoamine oxidase inhibitors might help. These medications work by blocking the breakdown of serotonin, dopamine, and norepinephrine, which can eventually reduce the frequency and intensity of panic attacks.
All right, as a quick recap, panic disorder is a mental health condition characterized by recurrent unexpected panic attacks, which are sudden episodes of intense fear that peak within minutes.
Often they are associated with physical symptoms due to sympathetic hyperactivity like racing heart and shortness of breath, as well as psychological symptoms due to amygdala hyperactivity such as derealization and
