A condition in which parting with objects (e.g., household items or personal possessions) causes significant distress. In addition, many individuals continuously acquire new things and experience distress if they are not able to do so. The inability to discard possessions can make living spaces nearly unusable. Relatedly, the cluttered living space can interfere with the performance of daily tasks, such as personal hygiene, cooking, and sleeping (e.g., the shower is full of stuff, the bed is covered with clutter).
Cognitive behavioral therapy focuses on the thinking patterns and behaviors that are sustaining or triggering your panic attacks and helps you look at your fears in a more realistic light. For example, if you had a panic attack while driving, what is the worst thing that would really happen? While you might have to pull over to the side of the road, you are not likely to crash your car or have a heart attack. Once you learn that nothing truly disastrous is going to happen, the experience of panic becomes less terrifying.
Post-Traumatic Stress Disorder affects people after terrifying events such as physical or sexual abuse, car accidents, war or natural disasters. Individuals with PTSD may experience depression, flashbacks, nightmares, sleep difficulties, irritability, aggression, violence, and a feeling of detachment or numbness. Symptoms can be triggered by anything that reminds the individual of their trauma.
Genetics and family history (e.g., parental anxiety) may predispose an individual for an increased risk of an anxiety disorder, but generally external stimuli will trigger its onset or exacerbation. Genetic differences account for about 43% of variance in panic disorder and 28% in generalized anxiety disorder. Although single genes are neither necessary nor sufficient for anxiety by themselves, several gene polymorphisms have been found to correlate with anxiety: PLXNA2, SERT, CRH, COMT and BDNF. Several of these genes influence neurotransmitters (such as serotonin and norepinephrine) and hormones (such as cortisol) which are implicated in anxiety. The epigenetic signature of at least one of these genes BDNF has also been associated with anxiety and specific patterns of neural activity.
It is not clear what causes panic disorder. In many people who have the biological vulnerability to panic attacks, they may develop in association with major life changes (such as getting married, having a child, starting a first job, etc.) and major lifestyle stressors. There is also some evidence that suggests that the tendency to develop panic disorder may run in families. People who suffer from panic disorder are also more likely than others to suffer from depression, attempt suicide, or to abuse alcohol or drugs.
Panic attacks and panic disorder are not the same thing. Panic disorder involves recurrent panic attacks along with constant fears about having future attacks and, often, avoiding situations that may trigger or remind someone of previous attacks. Not all panic attacks are caused by panic disorder; other conditions may trigger a panic attack. They might include:
Moreover, this hypocapnia and release of adrenaline during a panic attack cause vasoconstriction resulting in slightly less blood flow to the head which causes dizziness and lightheadedness. A panic attack can cause blood sugar to be drawn away from the brain and toward the major muscles. Neuroimaging suggests heightened activity in the amygdala, thalamus, hypothalamus, and brainstem regions including the periaqueductal gray, parabrachial nucleus, and Locus coeruleus. In particular, the amygdala has been suggested to have a critical role. The combination of high arousal in the amygdala and brainstem along with decreased blood flow and blood sugar in the brain can lead to dramatically decreased activity in the prefrontal cortex region of the brain. There is evidence that having an anxiety disorder increases the risk of cardiovascular disease (CVD). Those affected also have a reduction in heart rate variability.
As with most behavioral illnesses, the causes of panic attacks are many. Certainly there is evidence that the tendency to have panic attacks can sometimes be inherited. However, there is also evidence that panic may be a learned response and that the attacks can be initiated in otherwise healthy people simply given the right set of circumstances. Research into the causes of panic attacks is ongoing.
This may sound counter-intuitive but trying to accept one's emotional experience can be very helpful during panic attacks. Remind yourself that anxiety is like a wave, what goes up must come down. Fighting against the experience engages the "fear of fear" cycle that can make you feel even worse. If you notice panic symptoms creeping up, label your experience and you remind yourself, "I will be okay. This will pass in time." Accepting your experience, rather than fighting against it, will likely help your panic symptoms reduce more quickly and will feel easier along the way.
Research is inconsistent as to whether nutritional deficiencies (for example, zinc or magnesium deficiency) may be risk factors for panic disorder. While food additives like aspartame, alone or in combination with food dyes, are suspected to play a role in the development of panic attacks in some people, it has not been confirmed by research so far.
Mitral valve prolapse (MVP), also called "click murmur syndrome" and "Barlow's syndrome," is the most common type of heart valve abnormality. Usually, people with mitral valve prolapse have no signs and symptoms; however, if the prolapsed valve is severe, symptoms may appear. When symptoms of severe mitral valve prolapse do appear, they may include, fatigue, palpitations, chest pain, anxiety, migraine headaches, and pulmonary edema. Echocardiography is the most useful test for mitral valve prolapse. Most people with mitral valve need no treatment. However, if the valve prolapse is severe, treatment medications or surgery may be necessary to repair the heart valve.
Cognitive therapy and exposure therapy are two CBT methods that are often used, together or by themselves, to treat social anxiety disorder. Cognitive therapy focuses on identifying, challenging, and then neutralizing unhelpful or distorted thoughts underlying anxiety disorders. Exposure therapy focuses on confronting the fears underlying an anxiety disorder to help people engage in activities they have been avoiding. Exposure therapy is sometimes used along with relaxation exercises and/or imagery.
