While depression and anxiety are two different diagnoses, they often occur together. In fact, the Anxiety Disorders Association of America reports that almost half of all people who have a depressive disorder have an anxiety disorder as well. Understanding the signs of depression and anxiety can increase a person's odds of getting the appropriate treatment as early as possible.
Anxiety and Nervous Behavior
Anxiety can affect people with both depression and anxiety disorders. According to the Anxiety Disorders Association of America (ADAA), people with anxiety disorders tend to be plagued by excessive worry over day-to-day matters, even if there is no real cause for concern. People with depression may also be plagued by feelings of anxiety. In addition, the Mayo Clinic reports that they may be restless and irritable, and become annoyed more easily than usual.
Sleep Disturbances
Both depression and anxiety tend to cause sleep problems. Some people may have trouble sleeping (insomnia), or may wake early and be unable to fall back asleep. Others may sleep excessively. People who suffer from depressive disorder or anxiety disorders often appear tired and fatigued, likely for this reason. The Mayo Clinic also adds that those with depression may report feeling weak.
Muscle Tension and Aches
The Anxiety Disorder Association of America reports that muscle tension is a common sign of anxiety disorder. Depressive disorders may actually cause similar symptoms in some people. According to the National Institute of Mental Health (NIMH), people with depressive disorders often complain of generalized muscle aches and pains, in addition to headaches.
Digestive Upsets
Both depression and anxiety may cause unusual digestive symptoms. NIMH reports that cramps and associated digestive problems are common in those with depressive disorder. Similarly, the ADAA reports those with an anxiety disorder may experience stomach or intestinal discomfort, in addition to diarrhea. Some people with depression also experience weight loss or gain due to associated appetite changes.
Social Difficulties
Social problems may occur with anxiety disorders as well as depressive disorders. According to the Mayo Clinic, people with depressive disorder often lose interest in their usual daily activities, including sex. Depressive disorder can be so severe that it interferes with a person's relationships, and may also affect their performance at work or in school. The ADAA reports that those with anxiety disorders face similar difficulties: Excessive worries tend to disrupt their day-to-day routine, making even simple tasks challenging.
Alcohol Abuse
Alcohol abuse is a serious symptom that may be associated with both depression and anxiety. According to the ADAA, up to 20 percent of people with social anxieties abuse alcohol in some way. Alcohol abuse also increases one's risk of developing a depressive disorder. According to NIMH, both alcohol and substance abuse often co-exist with depressive disorders. Alcohol and substance abuse problems may be difficult to separate from anxiety and depressive disorders, making treatment challenging.
