Childhood Dystonia usually starts in one part of the body and can spread to the rest of the body. It can cause muscular pain and speech difficulties. It is sorted in these age groups.
- Childhood onset: younger than 12 years old
- Adolescent onset: 13 -20 years old
It’s caused in a variety of ways but the most common are:
- DYT1 gene which causes generalised dystonia, Usually affects the limbs first and progresses. This can cause severe disability. In some cases there may be no known cause and this is referred to as idiopathic dystonia
- DYT5 gene causes Dopa-responsive dystonia. Onset is during childhood usually beginning in the legs with sufferers progressively developing difficulty in walking
- DYT6 gene can cause adolescent-onset torsion, a mixed type
- Other Neurological conditions such as Dystonic Cerebral Palsy. Dystonic cerebral palsy often appears with symptoms of cerebral palsy and can cause a fixed, twisted posture
Caused by other factors such as head trauma

It is injected in certain muscles in the body and it blocks the chemical that causes muscle contractions. Treatment has been shown to be effective in reducing equinus gait pattern in these children (injections to calf, hamstring and hip flexor muscles), improving upper limb function (injections to shoulder, elbow, wrist and finger flexor muscles), reducing pain (injections to hip adductors) and reducing the need for orthopaedic surgery. Children with dystonia may also improve with botulinum toxin type A treatment, although muscle selection and dosing is clinically challenging. Source: Clinical use of botulinum toxin.

DBS is surgery where thin electrodes are inserted in an area of the brain and attached to a device implanted under the skin of the chest or in the abdominal wall.
