Miscellaneous non-epileptic head drop true true https://www.ncbi.nlm.nih.gov/pubmed/2369876 https://www.ncbi.nlm.nih.gov/pubmed/23531441 Non-epileptic head drops can occur in infants and may mimic epileptic spasms or atonic seizures. Infants typically experience frequent (more than a hundred) events per day, the head drop can be intense, may occur in a series (resulting in head bobbing) and may be accompanied by crying. The fall of the head (flexion of the neck) and rise of the head occur at the same velocity unlike in an epileptic seizure where the fall of the head is typically more rapid than the rise of the head. Non-epileptic head drops begin between age 3 - 6 months, and resolve by 12 months. Infants develop normally.
