Understanding Panic attacks

What is  a PANIC ATTACK...

A panic attack is a sudden surge of overwhelming anxiety and fear. Your heart pounds and you can’t breathe. You may even feel like you’re dying or going crazy. Left untreated, panic attacks can lead to panic disorder and other problems. They may even cause you to withdraw from normal activities. But panic attacks can be cured and the sooner you seek help, the better. With treatment, you can reduce or eliminate the symptoms of panic and regain control of your life.

In many cases, panic attacks strike out of the blue, without any warning. Often, there is no clear reason for the attack. They may even occur when you’re relaxed or asleep.

A panic attack may be a one-time occurrence, but many people experience repeat episodes. Recurrent panic attacks are often triggered by a specific situation, such as crossing a bridge or speaking in public—especially if that situation has caused a panic attack before. Usually, the panic-inducing situation is one in which you feel endangered and unable to escape.

You may experience one or more panic attacks, yet be otherwise perfectly happy and healthy. Or your panic attacks may occur as part of another disorder, such as panic disorder, social phobia, or depression. Regardless of the cause, panic attacks are treatable. There are many effective treatments and coping strategies you can use to deal with the symptoms.

Panic attacks often strike when you’re away from home, but they can happen anywhere and at any time. You may have one while you’re in a store shopping, walking down the street, driving in your car, or sitting on the couch at home.

The signs and symptoms of a panic attack develop abruptly and usually reach their peak within 10 minutes. Most panic attacks end within 20 to 30 minutes, and they rarely last more than an hour.

A full-blown panic attack includes a combination of the following signs and symptoms:

Shortness of breath or hyperventilation Heart palpitations or a racing heart Chest pain or discomfort Trembling or shaking Choking feeling Feeling unreal or detached from your surroundings

Sweating Nausea or upset stomach Feeling dizzy, light-headed, or faint Numbness or tingling sensations Hot or cold flashes Fear of dying, losing control, or going crazy

Is it a heart attack or a panic attack?

Most of the symptoms of a panic attack are physical, and many times these symptoms are so severe that people think they’re having a heart attack. In fact, many people suffering from panic attacks make repeated trips to the doctor or the emergency room in an attempt to get treatment for what they believe is a life-threatening medical problem. While it’s important to rule out possible medical causes of symptoms such as chest pain, heart palpitations, or difficulty breathing, it’s often panic that is overlooked as a potential cause—not the other way around.

Signs and symptoms of panic disorder

Many people experience panic attacks without further episodes or complications. There is little reason to worry if you’ve had just one or two panic attacks. However, some people who’ve experienced panic attacks 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.

Signs and symptoms of panic disorder

You may be suffering from panic disorder if you:

• Experience frequent, unexpected panic attacks that aren’t 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 you’ve 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 yourself 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.
• Phobic avoidance – You begin to avoid certain situations or environments. This avoidance may be based on the belief that the situation you’re avoiding caused a previous panic attack. Or you may avoid places where escape would be difficult or help would be unavailable if you had a panic attack. Taken to its extreme, phobic avoidance becomes agoraphobia.

• Medication treatment for panic attacks and panic disorder

  Medication can be used to temporarily control or reduce some of the symptoms of panic disorder. However, it doesn't treat or resolve the problem. Medication can be useful in severe cases, but it should not be the only treatment pursued. Medication is most effective when combined with other treatments, such as therapy and lifestyle changes, that address the underlying causes of panic disorder.
  The medications used for panic attacks and panic disorder include:
  • Antidepressants. It takes several weeks before they begin to work, so you have to take them continuously, not just during a panic attack.
  • Benzodiazepines. These are anti-anxiety drugs that act very quickly (usually within 30 minutes to an hour). Taking them during a panic attack provides rapid relief of symptoms. However, benzodiazepines are highly addictive and have serious withdrawal symptoms, so they should be used with caution.

Marijuana and Brain--Part 2

Marijuana and the Brain

After you inhale marijuana smoke, its chemicals are distributed throughout the body.

THC is a very potent chemical compared to other psychoactive drugs. An intravenous (IV) dose of only 1 milligram can produce serious mental and psychological effects. Once in your bloodstream, THC typically reaches the brain within seconds after it is inhaled and begins to go to work.

Marijuana users often describe the experience of smoking marijuana as initially relaxing and mellow, creating a feeling of haziness and light-headedness. The user's eyes may dilate, causing colors to appear more intense, and other senses may be enhanced. Later, feelings of a paranoia and panic may be felt by the user. The interaction of the THC with the brain is what causes these feelings. To understand how marijuana affects the brain, you need to know about the parts of the brain that are affected by THC. Here are the basics:

• Neurons are the cells that process information in the brain. Chemicals called neurotransmitters allow neurons to communicate with each other.
• Neurotransmitters fill the gap, or synapse, between two neurons and bind to protein receptors, which enable various functions and allow the brain and body to be turned on and off.
• Some neurons have thousands of receptors that are specific to particular neurotransmitters.
• Foreign chemicals, like THC, can mimic or block actions of neurotransmitters and interfere with normal functions.

In your brain, there are groups of cannabinoid receptors concentrated in several different places. These cannabinoid receptors have an effect on several mental and physical activities, including:

• Short-term memory
• Coordination
• Learning
• Problem solving

Cannabinoid receptors are activated by a neurotransmitter called anandamide. Anandamide belongs to a group of chemicals called cannabinoids. THC is also a cannabinoid chemical. THC mimics the actions of anandamide, meaning that THC binds with cannabinoid receptors and activates neurons, which causes adverse effects on the mind and body.

After you inhale marijuana smoke, its chemicals are distributed throughout the body.

High concentrations of cannabinoid receptors exist in the hippocampus, cerebellum and basal ganglia. The hippocampus is located within the temporal lobe and is important for short-term memory. When the THC binds with the cannabinoid receptors inside the hippocampus, it interferes with the recollection of recent events. THC also affects coordination, which is controlled by the cerebellum. The basal ganglia controls unconscious muscle movements, which is another reason why motor coordination is impaired when under the influence of marijuana.
