What causes stiffness eyes rolling into the back of head and not breathing for a few seconds in newborn?

The condition you are describing is called infantile spasms. It is a rare but serious neurological disorder that affects infants. Infantile spasms are characterized by sudden, brief seizures that cause the infant's body to stiffen and their eyes to roll back in their head. The seizures may also cause the infant to stop breathing for a few seconds.

The exact cause of infantile spasms is unknown, but it is thought to be caused by a disturbance in the electrical activity of the brain. Infantile spasms can occur in infants with any type of brain injury or abnormality, but they are most common in infants with certain genetic disorders, such as tuberous sclerosis and Down syndrome.

Infantile spasms can be difficult to diagnose, as they can be mistaken for other conditions, such as colic, reflux, or Sandifer syndrome. However, it is important to diagnose infantile spasms as early as possible, as early treatment can help to improve the infant's prognosis.

Treatment for infantile spasms typically involves medication, such as corticosteroids or adrenocorticotropic hormone (ACTH). In some cases, surgery may be necessary. Early diagnosis and treatment can help to improve the infant's prognosis, but infantile spasms can cause developmental delays and other long-term problems.

If you are concerned that your infant may be having infantile spasms, it is important to see a doctor right away.
