Limited symptom attack

Limited symptom attack

A Limited Symptom Attack (LSA), also referred to as a Limited Symptom Panic Attack (LPA), is a milder, less comprehensive panic attack with fewer than 4 panic related symptoms being experienced (APA 1994). For example, a sudden episode of intense dizziness or trembling accompanied by fear that something terrible is about to happen. Many people with panic disorder have a mixture of full blown and limited symptom attacks. LSAs often manifest in anxiety disorders, phobias, panic disorder and agoraphobia. However, experiencing a LSA is not necessarily indicative of mental illness. Often persons recovering from and/or being treated for panic attacks and panic disorder will experience LSAs.

Symptoms

According to the DSM-IV, during a LSA, fewer than 4 of the following symptoms would be experienced, in contrast to a full blown panic attack, which must include 4 or more symptoms.

* dyspnea (shortness of breath)
* heart palpitations
* trembling
* dizziness
* chest pain
* perspiration
* hot flashes
* headache
* derealization
* paresthesia
* hyperventilation
* nausea
* vertigo
* lightheadedness
* burning sensations
* choking sensations
* fear of dying
* fear of insanity

Duration

As with a panic attack, a LSA typically peaks in 10 minutes. However, attacks can be as short as 1 to 5 minutes or can form a series of episodes waxing and waning for a period of hours.
