Generalized anxiety disorder affects nearly 7 million people in the United States, equivalent to approximately 3.1% of the total population.

However, one alarming fact for health authorities is that only 43% of those affected receive a diagnosis and personalized treatment.

One of the main anxiety disorders is generalized anxiety disorder, but there are also other variants such as panic disorder.

There is also social anxiety disorder, which leads sufferers to avoid situations where they have to interact with too many people.

4. Depression

These can include loss of interest or pleasure in certain things, fatigue, insomnia and recurring thoughts associated with suicide.

In the U.S., there are 14.5 suicides reported per 100,000 residents per year. Timely diagnosis and access to personalized treatments are usually key to improving the quality of life for those suffering from depression.

This also minimizes symptoms that hinder them from carrying out daily activities and feeling fulfilled.

A study by the U.S. Department of Veterans Affairs found that in the United States, 6 out of 100 people suffer from post-traumatic stress disorder (PTSD).

This is a condition that usually develops after an event that has had a physical or emotional impact, such as experiencing or witnessing a serious accident.

This disorder is characterized by symptoms such as intrusive memories, where the sufferer relives flashbacks of the traumatic event, leading them to avoid situations, people or places that they find threatening.

Sleep disorders, mood changes and concentration problems are also symptoms of this disorder.
