Are Worry and Anxiety Related?


What is the relationship between anxiety and worry?  Can an individual worry and not feel anxious?  Similarly, can an individual feel anxious but not worried?  The age-old debate of which came first…the chicken or the egg once again applies.  In today’s post, I will discuss anxiety, theories of anxiety’s relationship to worry, its physiological symptoms and its origins.  The next post will discuss treatment options.

WHAT IS WORRY?

Is worry merely a different name for anxiety?  Worry is an integral component of anxiety, although worry is a process that can exist in the absence of anxiety.  Let’s identify worry as a primarily mental (thinking) activity.  When an individual worries, their mind is preoccupied with fear or dread. Often thoughts have a prevailing theme of negativity - rehearsing the worse case scenarios. Worry can range from the nagging little voice inside your head to unrelenting obsessions that can neither be ignored nor quieted.  Depending upon the severity of the negative thoughts and the permanency of those thoughts (statements that begin with never or always) some level of physiological reaction frequently follows.  Ultimately the mind convinces the nervous system to prepare for battle.  This then triggers a fairly predictable sequence of autonomic physical symptoms that characterize anxiety (e.g., fear, racing heart, sweating & tingling sensations).  In this theoretical framework, anxiety is identified as the reactive symptoms an individual feels within their body in response to their mental state of worry.

An alternative theory suggests that when an individual feels a myriad of undesirable physical symptoms that seemingly “come out of the blue” they often question their origin (a mental process) and may begin to either hyper-focus on the severity of the physical sensations or obsess about an ultimately fatal outcome when these symptoms worsen. Worry is the mental process triggered by feeling anxious rather than the cause of the anxiousness. Ultimately when worry sets in the autonomic system prepares either to take flight or to fight.  Some individuals may then experience the very scary physical symptoms known as a panic attack.  Following this logic, a panic attack is an extreme physical manifestation of anxiety. Understand that an individual may feel both worried and anxious and not experience a panic attack.

What conclusions can we draw from this chicken or egg debate?  Both positions identify a relationship between the mental processes and the physical symptoms that define the term anxiety.  Anxiety is neither all bad nor is it always a diagnosable condition!  Historically it has served as an alerting and preparation mechanism to safeguard us from impending danger.  For anxiety to meet DSM-V diagnostic criteria symptoms must be frequent, extreme and a source of ongoing distress (at least six months).

SYMPTOMS

Many symptoms of anxiety can mimic those of a heart attack - if you experience them seek medical attention immediately! Anxiety can present as chest pain or tightness in the chest, numbness and/or tingling in the arms and/or legs, labored breathing (as if an elephant is sitting on your chest), racing heart, cold sweats, dizziness, chills, tightness in the throat, elevated blood pressure, ringing in the ears, restlessness and/or agitation, gastrointestinal distress and most frequently a profound sense of impending doom.

Remember that when we’re anxious our bodies are activated to either flee or fight. A great illustration of this phenomenon has been captured by many National Geographic documentaries that feature hunting behaviors of animals in the wild.  The predator (lion) stalks and takes chase after unsuspecting prey (gazelle).  The gazelle exhibits the flight mode, the lion the fight mode.  Our brains have not yet evolved beyond these basic primal responses!

Additional physical symptoms of anxiety may include a cluster of symptoms characterized by tension: feeling keyed up or on edge, irritability, muscle tension, fatigue and sleep impairment.  Sleep impairment may range from difficulty falling asleep to early awakening to unsatisfying sleep (sleeping but not feeling rested).  Cognitive symptoms of anxiety may often include a temporary inability to recall names, events and previously over-learned information (mind going blank). The best example of this phenomenon is test anxiety-despite knowing the topic, the test appears to be written in a foreign language because the student cannot remember anything.  When a person feels anxious, it can also seem that any attempt to learn or take in new information is impossible.  This is another example of the mind going blank.  Once the anxiety dissipates, cognitive abilities return to their normal level of functioning. In summary, while the symptoms of anxiety are specific to the individual, general themes involve cardiac-like symptoms, tension symptoms and cognitive symptoms. Now let’s look at who, what and where regarding anxiety.

ORIGINS

Recent statistics indicate as of 2011, anxiety surpassed depression as the primary complaint identified by patients to their general practitioner.  Historically, women have been twice as likely as men to present with symptoms of anxiety.  Recent literature also suggests that men may be closing this gap as anxiety becomes less stigmatized within the general population.  Anxiety appears to be more prevalent in developed countries and spreads across lifespans.  The differentiating factors are age-related concerns.  For example, children may exhibit anxiety regarding school concerns while adolescents may be more likely to report anxiety regarding dating, school and independence.  Adults may report anxiety regarding advanced education, professional growth, marriage, families and aging parents.  The elderly may exhibit anxiety regarding their declining health status, grief from significant losses and their own death. 

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, cites “childhood adversities and parental overprotection” as risk factors for developing anxiety.  Also reported in this edition is that one-third of the risk of developing a diagnosable anxiety disorder may be related to genetic transmission.  This is roughly equivalent to the genetic factors associated with a diagnosis of major depression. The balance of the contributing influences may be related to personal temperament.  This means that certain individuals who are harm avoidant, behaviorally inhibited and display negative affect may be more susceptible to developing an anxiety disorder compared to individuals who are more comfortable with risk, are behaviorally extroverted and display positive affect.

CONCLUSION

As I stated earlier in this post, if you intermittently worry and feel anxious, that may simply be a reaction to specific life events and completely normal: life can be stressful!  To meet diagnostic criteria, symptoms must be extreme, chronic and incapacitating.  The presence of panic attacks, symptoms that necessitate frequent emergency room visits and symptoms that render an individual unable to maintain appropriate daily self-care and social relatedness are of significant concern to both behavioral health and primary care professionals. In these instances, after a thorough evaluation, a diagnosis of anxiety may be warranted.

Stay tuned for Part II where I will discuss treatment options.  Specifics regarding panic attacks will be discussed in a dedicated post on that topic.
