[citation needed] Management[edit] At present, only supportive management of symptoms is available as there is no known curative treatment for this condition. [en.wikipedia.org]
Walking and speech are delayed and moderate to profound intellectual impairment is virtually always present. Involuntary movements such as dystonia, ataxia, dyskinesias, and choreoathetosis are often seen. [disorders.eyes.arizona.edu]

Entire Body System
- Developmental Delay
The patients, who ranged from 3 to 21 years of age, had global developmental delay from infancy, including hypotonia and delayed walking or inability to walk (7 patients), poor or absent speech, and moderate to profoundly impaired intellectual development [findzebra.com]
delay or intellectual disability Sleep disturbance Episodic agitation Epileptic seizures are not a feature of this disorder (despite abnormal EEG) and head circumference is typically normal. [en.wikipedia.org]
There is general developmental delay with impaired intellectual development, delayed or absent walking, and behavioral psychiatric manifestations such as stereotypic and unpredictable outbursts. [disorders.eyes.arizona.edu]

Psychiatrical
- Head Banging
Abnormal behaviors such as outbursts of anger, poor attention span, head-banging, and self-mutilation are common. Central sleep apnea has been described. [disorders.eyes.arizona.edu]
