Prevalence and Incidence of Reflex sympathetic dystrophy syndrome

Reflex sympathetic dystrophy syndrome: Rare Disease

Reflex sympathetic dystrophy syndrome is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Reflex sympathetic dystrophy syndrome, or a subtype of Reflex sympathetic dystrophy syndrome, affects less than 200,000 people in the US population.

Complex regional pain syndrome: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

The exact cause of CRPS is unknown. Impaired communication between the damaged nerves of the sympathetic nervous system and the brain may cause interference with normal signals for sensations, temperature, and blood flow. This leads to problems in the nerves, blood vessels, skin, bones, and muscles. Infection or injury to an arm or leg may initiate CRPS. It can also occur after heart attacks and strokes. However, the condition can sometimes appear without obvious injury to the affected limb. This condition is more common in people between ages 40 and 60, but has been seen in younger people too. CRPS may also be seen in postoperative patients and in patients with diseases that can cause chronic pain, such as cancer and arthritis. Annual incidence is unknown because CRPS is often misdiagnosed. However, it has been reported in 1% to 2% of patients with various fractures and in 2% to 5% of patients with peripheral nerve injury.

Posttraumatic stress disorder: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

PTSD occurs in response to an extremely distressing event, including a serious threat of harm to the patient or his family, such as war, abuse, or violent crime. It may be triggered by sudden destruction of his home or community by a bombing, fire, flood, tornado, earthquake, or similar disaster. It may also follow witnessing the death or serious injury of another person by torture, in a death camp, by natural disaster, or by a motor vehicle or airplane crash.

Preexisting psychopathology can predispose some patients to this disorder, but anyone can develop it, especially if the stressor is extreme.

Any person who has experienced traumatic relocation due to such events as rioting or other civil strife, extreme natural disasters, or war should be assessed for signs of PTSD.

PTSD can occur at any age. Most cases resolve 3 months after the traumatic event, but some cases can last for years.

About prevalence and incidence statistics:

The term 'prevalence' of Reflex sympathetic dystrophy syndrome usually refers to the estimated population of people who are managing Reflex sympathetic dystrophy syndrome at any given time. The term 'incidence' of Reflex sympathetic dystrophy syndrome refers to the annual diagnosis rate, or the number of new cases of Reflex sympathetic dystrophy syndrome diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
