Generalized Anxiety Disorder: Symptoms, Causes and Treatments

He generalized anxiety disorder Is characterized by indiscriminate concern about anything. Concern can be useful as it prepares you for vital challenges (pass a test, do a job well), although in this disorder, such concern is unproductive and undesirable.

This excess of concern interferes with the functioning in daily life, since the person anticipates the disaster in different areas: money, death, family, friendships, relationships, work...

Each year 6.8 million Americans and 2% of European adults experience generalized anxiety disorder (TAG).

It is given twice as often in women as in men and is more common in people with a history of substance abuse and family members with a history of anxiety disorders.

Once the TAG is developed, it can be chronic, although it can be controlled with a correct treatment. In the United States it is the leading cause of disability at work.

Difference between"normal"concern and generalized anxiety disorder

Worries, fears and doubts are a normal part of life. It is normal to be anxious about qualifying on a test or worrying about home economics.

The difference between this type of normal concerns and those of the GAD is that the GAG ​​are:

Causes

As in other mental conditions, the exact cause of GAD is not known, but may include genetic factors and other risk factors.

Genetics

One-third of the variance of GAD is attributed to genes. People with a genetic predisposition to GAD are more likely to develop GAD, especially in response to a life stressor.

Substance use

The long-term use of Benzodiazepines May worsen anxiety, while reducing benzodiazepines may decrease their symptoms.

Also, long-term alcohol consumption is associated with anxiety disorders, with evidence that abstinence May lead to the disappearance of symptoms.

The recovery of benzodiazepines tends to take much longer than that of alcohol, but it can restore previous health.

Smoking tobacco has also been established as a risk factor for developing anxiety disorders, as is the consumption of caffeine.

Physiological mechanism

The TAG has been associated with an interruption of the operation of the amygdala And their processing of fear and anxiety.

Sensory information enters the amygdala through the complex basolateral nucleus. The basolateral complex processes memories related to fear and communicates the importance of threats to other places in the brain, such as the medial prefrontal cortex and sensory cortex.

Diagnosis

People with GAD may visit a doctor many times before discovering their disorder.

They ask doctors about their Headaches And sleep problems, although their true pathology is not always discovered.

Firstly it is advisable to go to a doctor to make sure there is no physical problem that is causing the symptoms. The doctor can then refer the patient to a mental health specialist.

Diagnostic Criteria for Generalized Anxiety Disorder - DSM V

The diagnostic criteria for generalized anxiety disorder, defined by DSM V, published by the American Psychologists Association (APA) is:

A. Excessive anxiety and worry (apprehensive expectancy), which occurs most days over a period of 6 months in relation to a number of activities or events.

B. The individual finds it difficult to control the concern.

When to seek help from a professional

As mentioned previously, some anxiety is normal, although it is advisable to go to a professional if:

  • You feel too much concern and interfere with work, personal relationships or other important areas of life.
  • Feeling depressed, problems with alcohol and other drugs
  • Other problems related to anxiety
  • Suicidal thoughts or behaviors.

Treatment

Behavioral-cognitive therapy (CBT) is more effective in the long term than medication (such as SSRIs), and although both treatments reduce anxiety, CBT is more effective in reducing depression .

Generalized anxiety is a disorder based on psychological components that includes cognitive avoidance, concerns, Problem resolution Ineffective and emotional processing, interpersonal problems, intolerance to uncertainty, emotional activation, poor understanding of emotions...

To combat previous cognitive and emotional aspects, psychologists often include some of the following components in the intervention plan: Relaxation techniques , Cognitive restructuring, progressive stimulus control, self-control, present-moment focus ( Mindfulness ), Problem-solving techniques, socialization, training in emotional skills, psychoeducation and acceptance exercises.

Cognitive-behavioral therapy (CBT)

The Cognitive-behavioral therapy (CBT) Is a method that requires working with the patient to understand how their thoughts and emotions influence their behavior.

The goal of therapy is to change negative thought patterns that guide anxiety, replacing them with more positive and realistic thoughts.

Elements of therapy include exposure strategies to allow the patient to confront their anxiety gradually and to feel more comfortable in the situations that provoke it.

CBT can be used alone or alongside the medication.

Components of CBT to treat GAD include: psychoeducation, self-observation, stimulus control techniques, relaxation techniques, self-management techniques, cognitive restructuring, exposure to concerns (systematic desensitization), and problem solving.

  • The first step in treatment is psychoeducation, which requires giving information to the patient about the disorder and its treatment. The purpose of education is to desigmatize the disease, build motivation for treatment and give realistic expectations about treatment.
  • Self-monitoring requires monitoring anxiety levels and the events that trigger it. Its goal is to identify the signs that cause anxiety.
  • Stimulus control aims to minimize the stimulatory conditions in which the concerns arise.
  • Relaxation techniques reduce stress.
  • With the cognitive restructuring is intended to build a more functional and adaptive vision about the world, the future and the patient.
  • Problem solving focuses on solving current problems.

It works best in combination with pharmacological treatments.

Therapy of intolerance to uncertainty

This therapy focuses on helping patients develop skills to tolerate and accept life uncertainty To reduce anxiety .

It is based on the psychological components of psychoeducation, awareness of concern, problem-solving training, imaginative and actual exposure, and recognition of uncertainty.

Motivational interview

A new approach to improving recovery rates in GAD is to combine CBT with motivational interviewing (MS).

It focuses on increasing Intrinsic motivation Of the patient and works, among other personal resources, empathy and self-efficacy.

It is based on open-ended questions and listening to promote change.

Medication

Different types of medication are used to treat GAD and should always be prescribed and supervised by a psychiatrist.

Although antidepressants can be safe and effective for many people, there may be risks for children, adolescents, and young adults.

  • SSRIs (selective serotonin reuptake inhibitors) are often the first line of treatment. Side effects can be diarrhea, headaches, sexual dysfunction, increased risk of suicide, serotonin syndrome...
  • Benzodiazepines: are also prescribed and may be effective in the short term. They carry some risks as the physical and piscológica dependence of the drug. They can also reduce attention and have been associated with falls in older people. They are optimal to consume in the short term. Some benzodiazepines are alprazolam, chlordiazepoxide, diazepam and lorazepam.
  • Other drugs: atypical serotonergic antidepressants (vilazodone, vortioxetine, agomelatine), triacyl antidepressants (imipramine, clomipramine), serotonin-norepinephrine reuptake inhibitors (SNRIs) (venlafaxine, duloxetine)...

Risk factor's

These factors may increase the risk of developing GAD:

  • Genetics: More likely to develop it in a family with a history of anxiety disorders.
  • Personality: A timid, negative or avoidant temperament may be more inclined to develop it.
  • Gender: Women are diagnosed more frequently.

Complications

Having TAGs can influence:

  • Problems in reconciling and maintaining sleep (insomnia).
  • Concentration problems.
  • Depression.
  • Substance abuse.
  • Digestive problems.
  • Headaches.
  • Heart problems.

Comorbidity

In a 2005 US survey, 58% of people diagnosed with major depression also had anxiety disorders. Among these patients the rate of comorbidity with GAD was 17.2%.

Patients with comorbid depression and anxiety tend to have greater severity and greater difficulty recovering than those with a single disease.

On the other hand, people with GAD have comorbidity with substance abuse of 30-35% and with drug abuse of 25-30%.

Finally, people with GAD may also have illnesses associated with stress, such as irritable bowel syndrome, insomnia, headaches and interpersonal problems.

Prevention

Most people with GAD need psychological treatment or medication, although making changes in lifestyle can also help a lot.

  • Stay physically active.
  • Avoid smoking and coffee.
  • Avoid alcohol and other substances.
  • Sleeping long enough.
  • Learn relaxation techniques.
  • Eat healthy.
