The defining characteristic of BPT is a tilting of an infant's head in recurrent episodes, for varying periods of time.[1][2] Furthermore, the child's trunk may bend in the same direction as the head, giving the baby an overall curved shape; this complaint is known as tortipelvis.[1][2] In addition to this, the individual may also, but not necessarily, experience vomiting, pallor, ataxia, agitation, infantile migraine, unsteadiness of gait upon learning to walk, general malaise and nystagmus.[1][2]
The periods in which the child's head is tilted and other symptoms appear can last anywhere from a few minutes to a few weeks, with a frequency of anywhere from two per year to two per month.[1][2]
Causesedit
The cause of benign paroxysmal torticollis in infants is thought to be migrainous. More than 50% of infants have a family history of migraine in first degree relatives. The cause is likely to be genetic.[1][2]
Pathophysiologyedit
The mechanism of action of benign paroxysmal torticollis is not yet understood.[1][2][3] It has been suggested that unilateral vestibular dysfunction[3] or vascular disturbance in the brain stem[1] may be responsible for the condition.
Diagnosisedit
Diagnosis of BPT can be difficult because it is rare.[3]
Treatmentedit
No known treatment for BPT currently exists.[1] However, the condition it is self-limiting and resolves after about eighteen months.
Prognosisedit
Benign paroxysmal torticollis disappears in the early years of life with no medical intervention.[1][2][3]
The condition was first described by CH Snyder in 1969 in an article titled “Paroxysmal torticollis in infancy. A possible form of labyrinthitis.” in the American Journal of Diseases of Children.[1][2][3]
