There are a number of Other Anxiety-Related Problems that have anxiety and fear as a core feature.
Hypochondriasis (Health Anxiety)
Hypochondriasis is a problem in which people are overly concerned about the possibility of having a serious disease, based on a tendency to misinterpret normal bodily symptoms.
A person with hypochondriasis may misinterpret a spot on the skin as a sign of skin cancer, or a headache as a sign of brain tumor.
People with hypochondriasis visit their doctors frequently to check out various physical symptoms, but the reassurance that they receive from the doctor rarely lasts very long.
Obsessive-Compulsive Personality Disorder (OCPD)
OCPD is a problem in which people are preoccupied with orderliness, perfectionism, and a need to be in control
People with OCPD tend to be overly concerned with details, rules, schedules, lists, and organization to the point that it is difficult for them to complete tasks; the original purpose of the activity often gets buried in a mountain of details.
People with OCPD often have difficulty delegating tasks to other people and are frequently described as overconscientious and rigid.
OCPD is often driven by anxiety-related beliefs that giving up control will lead to chaos in one’s life.
It can be difficult to distinguish it from some types of OCD; indeed, the two problems often co-occur.
Body Dysmorphic Disorder (Imaging Ugliness)
The core feature in this disorder is an imagined defect in appearance.
A person with BDD may be preoccupied with thoughts of having a big nose, an asymmetrical face, etc.
BDD shares features with other anxiety disorders such as social anxiety disorder and OCD.
Fear of Death
It is normal to fear death, and most of us do.
Fear of death is often a feature of another anxiety disorder. But excessive fear of death can also occur in the absence of another anxiety disorder.
