Neurosurgeon Explains High Risks from ‘Small Falls’ — Especially for Older Adults

Serious injuries are often associated with major accidents. But what about tumbles? A trip over a rug, a slip on a wet floor, or a bump against a piece of furniture might seem minor. Yet even these seemingly insignificant falls can have serious, slow-developing consequences for the brain — especially for older adults.

A “small fall” can still cause significant brain changes, and symptoms often appear gradually, according to Brian Snelling, M.D., director of cerebrovascular and endovascular neurosurgery at Marcus Neuroscience Institute at Boca Raton Regional Hospital, part of Baptist Health. This delayed onset can make it difficult to link new health issues back to the original incident, adds Dr. Snelling, who also serves as stroke program director at the institute.

Understanding the risks — and knowing what to look for — is crucial for protecting your health or the health of a loved one.

Why Are Older Adults More Vulnerable?

As we age, the body undergoes natural changes that can increase susceptibility to injury, particularly from falls. The brain is no exception.

“With age, the brain can naturally shrink a bit,” Dr. Snelling explains. This process, known as brain atrophy, creates more space between the brain and the skull. That extra room allows the brain to move more freely during even a minor jolt, potentially tearing delicate blood vessels along its surface.

“With a sudden fall or small jolt, some bleeding can develop, and those symptoms may not necessarily be recognized immediately,” he adds.

This slow bleeding — called a subdural hematoma — gradually increases pressure on the brain. Because the process unfolds slowly, symptoms may not appear for days, weeks or even months.

Everyday Slips with Serious Potential

When we think of a fall, we often imagine a dramatic event. In reality, many slow-developing brain injuries stem from very ordinary incidents — particularly around the home.

Examples of seemingly minor falls or jolts that can impact the brain include:

• Missing a step: Misjudging the last step on a staircase.
• Slipping on a surface: Losing footing on a wet kitchen floor, ice, or a polished surface.
• Tripping over an object: Catching a foot on a throw rug, pet, electrical cord or clutter.
• Losing balance: Feeling dizzy and bumping into furniture or a wall.
• Sudden stops in a vehicle: Abrupt braking that causes the head to jolt forward and backward.

In many cases, the person may not even fall to the ground — they might catch themselves on a counter or chair. Without obvious injuries like fractures or deep cuts, it’s easy to dismiss the event as harmless. Internally, however, the brain may still be affected.

The Slow Onset of Symptoms

One of the most deceptive aspects of these injuries is how gradually symptoms develop. Unlike a concussion from a sports injury, which often causes immediate signs, a slow brain bleed may produce subtle changes that are easily mistaken for normal aging.

“Patients can develop headaches or difficulty speaking or walking — and that can develop over the next few weeks to months,” Dr. Snelling says.

Family members and caregivers are often the first to notice changes. Paying attention to subtle shifts is critical, especially if the person has experienced any fall, no matter how minor.

Symptoms to watch for include:

• New or worsening headaches: Persistent headaches that don’t improve with typical remedies.
• Changes in balance or walking: New unsteadiness, a wider gait or reliance on furniture for support.
• Confusion or memory issues: Difficulty with familiar tasks or increased forgetfulness.
• Increased drowsiness: Sleeping more than usual or difficulty waking.
• Personality changes: Increased irritability, withdrawal or apathy.
• Weakness on one side: Gradual loss of strength in an arm or leg.

Because these symptoms can resemble other conditions, the connection to a fall weeks earlier is often missed.

Don’t Wait: The Importance of Early Detection

When it comes to brain health, time matters. Ignoring subtle symptoms can allow pressure on the brain to increase, potentially leading to lasting cognitive or physical impairment.

The good news is that slow brain bleeds are often treatable, especially when identified early. Imaging tests such as CT scans or MRIs can confirm a diagnosis, and treatment may range from monitoring to procedures that relieve pressure on the brain.

Dr. Snelling offers clear guidance: “If you or someone you know experiences a fall or head injury and develops symptoms days or weeks later, don’t wait to get checked out. Early detection can make all the difference.”
