Anxiety versus Panic
The terms anxiety attack and panic attack are often used interchangeably to mean the same thing. In this sense, the difference is purely a matter of semantics. But from a clinical perspective, panic and anxiety are defined by different features.
The differences between panic and anxiety are best described in terms of the intensity of the symptoms and length of time the predominant symptoms occur.
During a panic attack, the symptoms are sudden and extremely intense. These symptoms usually occur “out of the blue,” peak within 10 minutes and then subside. However, some attacks may last longer or may occur in succession, making it difficult to determine when one attack ends and another begins.
Anxiety, on the other hand, generally intensifies over a period of time and is highly correlated to excessive worry. The symptoms of anxiety are very similar to the symptoms of panic attacks and may include:
Another important distinction is that, unlike a panic attack, the symptoms of anxiety may be persistent and very long lasting -- days, weeks or even months.
