A learning disability is a general term that describes specific kinds of learning problems that cause a person to have difficulty acquiring certain skills. The skills most often affected are reading, writing, math, listening, speaking, and reasoning.
Osteopenia usually has no symptoms. There is no pain or any other sign to signal that the bone is becoming thinner, although there may be incidences of frequent fractures as the bones tend to become fragile and soft.
Symptoms of osteoarthritis most often develop gradually and include: 1  Joint aching and soreness, especially with movement. 2  Pain after overuse or after long periods of inactivity. 3  Stiffness after periods of rest. 4  Bony enlargements in the middle and end joints of the fingers (which may or may not be painful). 5  Joint swelling.
