SLEEP-WAKE TRANSITION DISORDERS

The sleep wake transition disorders are the disorders that occur in the transition from sleep to wakefulness or wakefulness to sleep.
Rhythmic movement disorder - This is a condition commonly seen in infants. It is characterized by
rhythmic movements of the body at sleep onset. The manifestations may be head banging, body rocking or a combination of both. The body rocking is seen more in the first year of life and the head banging predisposes in older children. This usually resolves in the 2nd or 3rd year of life. Complications are unlikely however severe trauma can result in subdural hemorrhages and retinal petechiae.
ICSD diagnostic criteria:

• Headbanging
• Headrolling

• Body rolling
• Onset typically within the first 2 years of life
• DPSG findings of rhythmic movement in sleep and no seizure activity.
• No other medical or mental disorder
• Symptoms do not meet diagnostic criteria for other sleep disorders producing abnormal movements in sleep.
