People who have repeated, persistent attacks or feel severe anxiety about having another attack are said to have panic disorder. Panic disorder is strikingly different from other types of anxiety disorders in that panic attacks are often sudden and unprovoked. However, panic attacks experienced by those with panic disorder may also be linked to or heightened by certain places or situations, making daily life difficult.
In the past it might have taken months or years and lots of frustration before getting a proper diagnosis. Some people are afraid or embarrassed to tell anyone, including their doctors or loved ones about what they are experiencing for fear of being seen as a hypochondriac. Instead they suffer in silence, distancing themselves from friends, family, and others who could be helpful. Other people suffering from panic attacks don't know they have a real and highly treatable disorder. It is our hope that through increased education, people will feel more empowered to discuss their symptoms with a healthcare professional and seek appropriate treatment.
But over time, you may find yourself experiencing more panic attacks, in a variety of circumstances. Most of these will not be entirely unexpected. Most subsequent attacks occur in response to various cues such as entering a crowded area; a traffic jam; or simply worrying about having a panic attack. But there may still be some surprises: for instance, you might have a nocturnal panic attack, which wakes you out of a sound sleep. Or you might find yourself experiencing odd feelings of depersonalization as you kill some time with friends or colleagues.
Furthermore, certain organic diseases may present with anxiety or symptoms that mimic anxiety. These disorders include certain endocrine diseases (hypo- and hyperthyroidism, hyperprolactinemia), metabolic disorders (diabetes), deficiency states (low levels of vitamin D, B2, B12, folic acid), gastrointestinal diseases (celiac disease, non-celiac gluten sensitivity, inflammatory bowel disease), heart diseases, blood diseases (anemia), cerebral vascular accidents (transient ischemic attack, stroke), and brain degenerative diseases (Parkinson's disease, dementia, multiple sclerosis, Huntington's disease), among others.
Anxiety disorders fall into a set of distinct diagnoses, depending upon the symptoms and severity of the anxiety the person experiences. Anxiety disorders share the anticipation of a future threat, but differ in the types of situations or objects that induce fear or avoidance behavior. Different types of anxiety disorder also have different types of unhealthy thoughts associated with them.
Anxiety attack disorder generally starts with one unexplained attack that can include a number of intense anxiety attack symptoms, which causes the individual to become concerned. As other attacks occur, fear of having anxiety attacks, what they mean, what the associated symptoms mean, and where the attacks and symptoms may lead, increases. This escalation of fear is often the catalyst that brings on the attacks, causing the individual to be seemingly caught in a cycle of fear then panic, then more fear, then more panic, and so on.
Over time, many who suffer panic attacks develop an on-going fear of having another attack. This fear can severely hamper daily activities and overall quality of life. Some people refuse to leave their houses or to put themselves in situations that remind them of their previous attacks. Agoraphobia (a fear of being outside of known and safe surroundings) or other mental problems may follow.
People with generalized anxiety disorder (GAD) display excessive anxiety or worry, most days for at least 6 months, about a number of things such as personal health, work, social interactions, and everyday routine life circumstances. The fear and anxiety can cause significant problems in areas of their life, such as social interactions, school, and work.
