Signs Of Leigh's Disease

Lack Of Muscle Tone

Lack of muscle tone is also known as hypotonia. It means an individual's body is limp and weak, and the muscles cannot provide adequate resistance. This happens when the brain struggles to tell the muscles to contract. In Leigh's disease, this happens due to brain damage. An infant with a lack of muscle tone will appear to be droopy and have unusually relaxed limbs. For this reason, hypotonia is sometimes given the nickname 'floppy baby syndrome.' The infant may have trouble sitting up or raising their head. They will also tend to have bad reflexes.
