10 Angelman Syndrome Symptoms
Symptom #10: Hypotonia of Trunk with Hypertonia of Limbs
Hypotonia is a term that refers to low muscle tone where there can be reduced muscle strength. Hypotonia is not a specific medical disorder but can be seen in various conditions such as autism spectrum disorder, achondroplasia, Down syndrome, Ehlers-Danlos syndrome, fragile X syndrome, neurofibromatosis, Patau syndrome, and more.
Hypertonia is a term that is sometimes used synonymously with rigidity or spasticity. It usually occurs when there is damage to the central nervous syndrome. However, in individuals with Angelman syndrome, they tend to have hypotonia of the trunk (body) with hypertonia of the limbs (arms and legs).
