Shaken Baby Syndrome – Symptoms and Causes

Overview

Abusive head trauma in infants, often called shaken baby syndrome, occurs when a baby is violently shaken. This dangerous form of child abuse can cause severe brain damage by destroying brain cells. In the worst cases, it may lead to death.

When a baby is shaken forcefully, the brain moves within the skull, causing bruising, swelling, and bleeding. Young infants are especially vulnerable because their neck muscles are weak and their heads are proportionally large.

The good news is that this type of injury is completely preventable. Resources exist to help parents who feel overwhelmed or frustrated.

It’s also important for parents to carefully educate anyone who cares for their child about the dangers of shaking a baby.

Signs and Symptoms

Babies who have been violently shaken may show several concerning symptoms. These can include extreme fussiness, trouble staying awake, and problems breathing.

The baby might not eat well, may vomit, or have skin that looks pale or odd in color.

More serious symptoms include seizures, paralysis, and even coma. Many times, you won’t see any marks or bruises on the outside of the baby’s body, even though serious damage might be happening inside.

Inside injuries can include bleeding in the brain and eyes, damage to the spinal cord, and broken bones in the ribs, skull, legs, or other areas. Often, children who have been shaken show signs that they’ve been hurt before.

In mild cases, a baby might seem fine at first. However, health or behavior problems may develop later.

When to Get Medical Help

If you think a baby has been injured by shaking, get help immediately. Call 911 or go to the nearest emergency room right away. Quick medical care could save the baby’s life or prevent serious health problems.

Remember that healthcare workers must report all suspected cases of child abuse to authorities. This is required by law to help protect children from harm.

Causes

Infants have underdeveloped neck muscles that cannot properly support their heads. When a baby is violently shaken, their brain moves within the skull cavity, causing damaging contact with the skull’s interior.

This movement can lead to bruising, swelling, and bleeding in the brain.

Most cases of shaken baby syndrome occur when a frustrated parent or caregiver shakes an infant forcefully. The leading trigger is typically prolonged crying that the adult cannot stop or soothe.

It’s important to note that normal activities do not cause this syndrome:

• Gentle bouncing on a knee
• Minor falls
• Regular play activities

The condition results specifically from forceful, violent shaking motions.

Risk Factors

Several factors may increase the chance of a baby being shaken:

• Unrealistic expectations about baby behavior.
• Excessive crying that frustrates caregivers.
• Premature birth or babies with special medical needs.
• Caregiver characteristics such as young age or single parenthood.

Stress, family violence, and alcohol or drug use can worsen the situation. Unstable home environments, depression, and adults who were mistreated as children may also be at higher risk of shaking a baby.

Men are more likely than women to shake a baby forcefully enough to cause serious harm.

Complications

Shaking an infant, even for a short time, can cause permanent brain damage. Many babies who experience this trauma don’t survive.

Survivors often face serious long-term health problems, including:

• Complete or partial loss of vision
• Developmental delays
• Learning disabilities and behavioral problems
• Epilepsy or recurring seizures
• Cerebral palsy, affecting movement control and coordination

These conditions typically require ongoing medical care throughout the child’s life. The damage caused by shaking cannot be reversed, making prevention absolutely critical.

Ways to Prevent Infant Shaking Injuries

Parents can protect their babies by learning about the dangers of shaking and how to cope with crying. Taking parenting classes helps build skills for calming fussy babies and managing stress properly.

Always handle your baby gently, even during long crying episodes. Remember that no matter how frustrated you feel, shaking is never an acceptable response to crying.

If you’re feeling overwhelmed by parenting:

• Ask for help from family or friends.
• Take a short break when the baby is safely in the crib.
• Seek professional support through your healthcare provider.

Anyone who cares for your baby should understand these dangers. Be sure to educate:

• Babysitters and Nannies
• Older Siblings
• Grandparents
• Other Family Members

Make sure to take care of your own mental health for safe parenting. Don’t hesitate to connect with counseling services if parenting stress becomes difficult to manage.
