What is the prognosis of infantile neuroaxonal dystrophy (INAD)?

Infantile neuroaxonal dystrophy (INAD) is a progressive disease. Once symptoms begin, they worsen over time. Generally, a baby's development starts to slow down between the ages of six months and three years. The first symptoms may be slowing of motor and mental development, followed by loss or regression of previously acquired skills. Rapid, wobbly eye movements and squints may be followed by floppiness in the body and legs (more than in the arms). For the first few years, a baby with INAD will be alert and responsive despite being increasingly physically impaired. Eventually, because of deterioration in vision, speech, and mental skills, the child will lose touch with its surroundings. Death usually occurs between the ages of 5 and 10 years.
