The medical definition of anxiety provided in the Merriam-Webster Dictionary is “an abnormal and overwhelming sense of apprehension and fear often marked by physical signs (such as tension, sweating, and increased pulse rate), by doubt concerning the reality and nature of the threat, and by self-doubt about one’s capacity to cope with it.” Anxiety is the body’s natural response to stress and depending on its severity can manifest in a variety of ways, including:

  • Causes the amygdala to enlarge: An enlarged amygdala (area of the brain that perceives feelings of stress, anxiety, irritability, and processes fear) intensifies the body’s response to threatening or scary situations. 
  • Shrinks the hippocampus: The hippocampus (area of the brain associated with learning and memory) connects to the amygdala, and together they control emotional memory recalling and regulation.
  • Weaken structural brain connections: Anxiety can weaken the connection between the amygdala and pre-frontal cortex (area of the brain that reigns rational thought, impulse control, executive planning, and more), making it difficult for the prefrontal cortex to send a logical response to danger to the amygdala. This can increase one’s sensitivity to danger and hinder one’s ability to develop rational responses.

Anxiety can also adversely affect one’s excretory and digestive systems, leading to loss of appetite, stomachaches, nausea, diarrhea, and other digestive issues. 

Anxiety Attack: Signs and Symptoms

When an individual experiences a sudden and intense episode of fear and anxiety it is known as an anxiety attack. The following examples include signs and symptoms that can be the result of anxiety, many of which are commonly associated with anxiety attacks, provided by Medical News Today:

  • Loss of concentration
  • A rapid heart rate
  • Restlessness 
  • Dizziness
  • Shortness of breath
  • Dry mouth
  • Chest pain
  • Being easily startled
  • Sleep disturbances
  • Fear 
  • Muscle aches and pains
  • Irritability
  • Numbness or tingling in the extremities
  • Feeling of choking
  • Worry and/ or distress

Anxiety attacks can range in severity and duration. Each person is unique and as such different triggers can initiate the onset of anxiety and/ or anxiety attacks in different people. Typically, the symptoms of anxiety attacks come on suddenly, and the intense symptoms can leave a person with residual effects of anxiety long after (e.g., hours, weeks, or even months) an anxiety attack has subsided.
