Many panic attack sufferers report that panic hits them with no warning at all; others do have a sense of building panic leading up to a full-blown attack.
According to a recent study reported at Science Daily (www.sciencedaily.com), there appears to measurable physiological changes occurring for at least an hour preceding a panic attack. This would suggest that attacks do not “come out of the blue,” but that sufferers are not aware of the internal changes taking place prior to a panic attack.
From the article:
“A study based on 24-hour monitoring of panic sufferers while they went about their daily activities captured panic attacks as they happened and discovered waves of significant physiological instability for at least 60 minutes before patients’ awareness of the panic attacks, said psychologist Alicia E. Meuret at Southern Methodist University in Dallas.”
