Ankylosing spondylitis (AS) is a chronic inflammatory type of arthritis that primarily affects the spine and the sacroiliac joints. It can cause stiffness in the spine and other joints, as well as pain. The age at which ankylosing spondylitis starts is variable, and can range from a few months old to late adulthood.
Early Onset Ankylosing Spondylitis
Early onset ankylosing spondylitis is rare but can affect people under the age of 16. Symptoms in these cases can include back pain, stiffness, and swelling in the affected areas. Other symptoms can include fever, fatigue, and weight loss. Diagnosis is typically made through physical examination and imaging tests such as X-rays and MRI scans. Treatment typically involves the use of non-steroidal anti-inflammatory drugs (NSAIDs) and physical therapy.
Adult Onset Ankylosing Spondylitis
Adult onset ankylosing spondylitis is much more common than early onset and typically affects people in their 20s and 30s. Symptoms of adult onset ankylosing spondylitis can include back pain, stiffness, and fatigue. Other symptoms may include fever, weight loss, and eye inflammation. Diagnosis is typically made through physical examination, imaging tests, and sometimes through blood tests. Treatment typically involves the use of NSAIDs, physical therapy, and sometimes biologic medications.
Late Onset Ankylosing Spondylitis
Late onset ankylosing spondylitis is rare and typically affects people in their 50s or older. Symptoms can include back pain, stiffness, and fatigue. Diagnosis is typically made through physical examination, imaging tests, and sometimes through blood tests. Treatment typically involves the use of NSAIDs, physical therapy, and sometimes biologic medications.
