10 Symptoms of Rett Syndrome

6. Loss of Muscle Control

After the first signs of loss of hand control, the loss of control in other muscles and limbs is imminent. The baby or child may not be able to crawl or walk properly as muscles become weaker. They may also take on a rigid form of spasticity. This degeneration of the ability to control the muscles may occur very quickly. Documentation suggests that after the first initial bout of regression, the rate of reduction of movement slows as the child gets older.
