Generalized anxiety disorder- symptoms, caused, risk factors and treatments

Generalized anxiety disorder (GAD) is a common type of mental disorder typically characterised by excessive constant worry over different things. Learn everything about generalized anxiety disorder, its causes, symptoms, risk factors, prevention, and treatment.

According to a population study, not less than 33.7 per cent of the population are affected by an anxiety disorder. Anxiety disorders include generalized anxiety disorder, specific phobias as well as social anxiety disorder.

Like most other types of mental health disorders, people with generalized anxiety disorder usually do not control their feelings. This condition comes with chronic anxiety and worries over common situations and occurrences.

It is normal to get worried at some point over certain issue of life. However, in the case of GAD, the feeling of anxiousness is not normal. For instance, someone with a generalized anxiety disorder might worry excessively over financial issues many times a day for up to two months, even when there is no need to worry.

Generalized anxiety disorder is one of the most common mental disorders associated with societal and personal costs yet it is the least successfully treated of the anxiety disorders.

The symptoms of generalized anxiety disorder are similar to obsessive-compulsive disorder and panic disorder. However, the conditions differ. The excessive anxiety and unrealistic worry that is associated with GAD can interfere with people's relationships as well as their daily activities.

Difference between GAD and other common mental conditions

Many mental issues like phobias and depression also present with anxiety. However, generalized anxiety disorder differs from these conditions in different ways.

People with phobia usually worry and exhibit fear about one particular thing, and people with depression may feel anxious sometimes.
