Anxiety Disorders Health Center

Many anxiety disorders can be associated with panic disorder, depression, and obsessive-compulsive disorder. Often individuals will have multiple anxiety disorders. In some cases theses disorders are the impetus for individuals to seek medical treatment.


There is some research demonstrating a link between drug addiction and OCD as well. Many who suffer from OCD also suffer from panic attacks. There is a higher risk of drug addiction among those with any anxiety disorder (possibly as a way of coping with the heightened levels of anxiety), but drug addiction among OCD patients may serve as a type of compulsive behavior and not just as a coping mechanism. Depression is also extremely prevalent among sufferers of OCD.


The majority of patients with PTSD also have at least one other disorder. The most common disorders to occur alongside PTSD include depression, alcohol and drug abuse, and other anxiety disorders.

Alcohol and substance abuse problems are prevalent in those who suffer from PTSD. Men tend to suffer from these problems more often then women, though they occur in women as well.


The most common complementary psychiatric condition is unipolar depression. Besides depression, the most common disorders diagnosed in patients with social anxiety disorder are panic disorder, generalized anxiety disorder, post-traumatic stress disorder, and substance abuse disorder. Avoidant personality disorder is also highly correlated with social anxiety disorder. Because of its close relationship and overlapping symptoms with other illnesses, treating social anxiety disorder may help understand underlying connection in other psychiatric disorders.


Other anxiety disorders, depression, or substance abuse often accompany GAD, which rarely occurs alone. GAD is commonly treated with medication or cognitive-behavioral therapy, but co-occurring conditions must also be treated using the appropriate therapies.

Panic Disorder

Panic disorder is often accompanied by other serious problems, such as depression, drug abuse, or alcoholism. These conditions need to be treated separately. Symptoms of depression include feelings of sadness or hopelessness, changes in appetite or sleep patterns, low energy, and difficulty concentrating.

Most people with depression can be effectively treated with antidepressant medications, certain types of psychotherapy, or a combination of the two.
