Trauma is a natural emotional reaction to terrible experiences that involve actual or threatened serious harm to oneself or others. However, for some people, the thoughts or memories of these events seriously affect their lives, long after any real danger has passed. This is posttraumatic stress disorder (PTSD), a serious anxiety disorder.
The study of human anxiety disorders has benefited greatly from functional neuroimaging approaches. Individual studies, however, vary greatly in their findings.

Professionals working in primary healthcare settings are likely to come into contact with older adults suffering with anxiety disorders. These disorders are often difficult to distinguish from the normal worries of older adults, from nervous personalities, physical illnesses with symptoms similar to some that accompany anxiety, and mental and emotional changes related to the development of cognitive impairment or dementia.
Although anxiety disorders are common at all ages, there is a misconception that their prevalence drastically declines with age. For this reason anxiety disorders often are underdiagnosed and undertreated in geriatric patients, especially when the clinical presentation of these disorders in older patients differs from that seen in younger adults.
Excessive anxiety that causes distress or that interferes with daily activities is not a normal part of aging, and can lead to a variety of health problems and decreased functioning in everyday life. Between 3% and 14% of older adults meet the criteria for a diagnosable anxiety disorder.
Anxiety disorders are the most prevalent mental health conditions, and in any given year, about 10% of adults aged 65 and older experience a diagnosable anxiety disorder. Over their lifetimes, about 15% of those who survive past the age of 65 will have had an anxiety disorder.
