Margaret was 68 years old when she fell getting up from the couch. Her daughter helped her up, checked for bruises, and ordered a grab bar for the bathroom. Two weeks later, Margaret fell again, this time in the kitchen. Then again, six weeks after that, in the hallway. Each fall had its own explanation: she was tired, her socks were slippery, she turned too fast.
Nobody stopped to ask what was actually happening.
That is one of the most common and costly mistakes families make when a loved one starts falling regularly. A fall is an event. Repeated falls are a pattern. And patterns have causes. The cause might be a medication that nobody has reviewed in two years. It might be an infection she cannot feel. It might be a vision problem nobody caught. Or it might be something in the brain that is changing and has not yet been named.
This article will help you understand what dementia really is, why some types affect the body before they affect the memory, what research is now telling us about the connection between falls and future brain health, and, most importantly, what you need to demand from your loved one’s medical team right now.
Dementia Is Not a Single Disease
Most people hear the word “dementia” and picture one thing: forgetting names, forgetting faces, getting lost on a familiar street. That image is real, but it is incomplete. “Dementia” is not a diagnosis. It is an umbrella term, a word that covers at least 13 known conditions, each one different in how it begins, how it moves through the body, and what it steals first.
Here are five of the most common types:
Alzheimer’s Disease: Accounts for 60 to 80 percent of all dementia cases. Memory is usually the first thing affected, and the progression is gradual over many years.
Vascular Dementia: Caused by damage to the blood vessels that supply the brain. Thinking slows, and processing becomes difficult. Balance problems can appear early, sometimes before memory is noticeably affected.
Lewy Body Dementia: Includes visual hallucinations, sleep disturbances, and significant movement and balance problems that closely resemble Parkinson’s disease. Falls can happen in the early and middle stages.
Frontotemporal Dementia: Affects personality and behavior first. The person may say things that seem cruel or out of character, make poor decisions, or lose the ability to feel empathy, all while their memory remains largely intact for years.
Mixed Dementia: Two or more types occurring at the same time, more common than most people realize, especially in people over 75.
Your loved one’s doctor may say “dementia” without explaining which kind. That word alone is not enough information. Each type behaves differently, and some types will affect how a person moves long before they forget a single name.
When Dementia Takes Away the Ability to Walk
Every type of dementia, without a single exception, will eventually take away a person’s ability to walk without help. This is not a side effect. It is a direct consequence of brain damage spreading into the regions that control balance, coordination, posture, and gait. Families are often stunned when it happens because nobody told them to expect it.
What surprises families even more is this: for some types of dementia, the legs go before the memory does.
He still remembered every grandchild’s birthday. He still beat everyone at cards. But he had fallen four times in six weeks, and his walk had become slow and shuffling, with short, dragging steps. His brain was already changing. His memory just had not caught up yet.
Vascular dementia can produce exactly that picture: a person who seems cognitively intact but whose balance and gait are already deteriorating. Lewy body dementia brings motor symptoms that look like Parkinson’s disease, including postural instability and a serious risk of falls, often in the earlier stages of the illness. A condition called Normal Pressure Hydrocephalus, which is sometimes mistaken for dementia and is sometimes treatable, lists gait disturbance as one of its first and most visible signs.
The point is not to frighten you. It is to make sure you know that unsteady walking and repeated falling are not always “just getting older.” They can be the body’s earliest visible signal that something is happening in the brain.
Frequent Falls May Signal Brain Changes, or Something Entirely Fixable
A 2026 review of nearly three million adults aged 40 and older found that people with a history of multiple falls had a 74 percent higher risk of developing dementia compared to those who had never fallen. That is a number worth sitting with.
But here is what it does not mean. It does not mean that falling causes dementia. It does not mean your mother is headed toward dementia because she fell twice last month. What it means is that repeated falls can be one of the first signs that the body is already beginning to change, and that when falls keep happening, the investigation matters enormously.
Could be serious. Could be fixable. You will not know without looking.
A urinary tract infection can look like a brain problem. A blood pressure medication that is too strong can cause a sudden drop in pressure the moment someone stands up, and down they go. A person squinting to see the edge of a step is a person about to miss it. Each of those causes is real, common, and in many cases correctable. The fall is the warning light on the dashboard. Your job is to find out what is triggering it.
When Falls Keep Happening: Four Things That Must Be Investigated
Two falls in one month. Then a third. The care team documents each one, adjusts the bed height, and reminds everyone to use the call button. But nobody asks the question that matters most: why is this person falling?
Recurrent falls demand a serious, systematic investigation into cause, not just management of the event itself. Four areas must be addressed before any fall gets written off as inevitable.
Rule Out Infection First
Infections, particularly urinary tract infections and pneumonia, can cause sudden-onset confusion, profound muscle weakness, and dangerous unsteadiness in older adults. A UTI alone can turn a steady person into someone who cannot safely cross a room. The troubling part is that older adults often do not have the classic signs of infection: no fever, no obvious pain, nothing that announces itself clearly. What appears instead is a sudden, unexplained change in function.
She had fallen twice in three days. The family assumed she was declining fast and started researching memory care communities. A urine culture showed a severe infection. Forty-eight hours of antibiotics later, she was walking to the kitchen on her own.
Before accepting that a loved one “just falls now,” rule out infection. It is a simple step that is skipped far too often.
Rule Out Vision and Hearing Problems
A person who cannot clearly see a change in floor level cannot protect themselves from it. A person who cannot hear a warning call from across the room is working with incomplete information at every moment. Impaired vision and hearing are well-documented, directly modifiable fall risk factors that are consistently undertreated in older adults.
When did your loved one last have a proper eye exam, not just a quick screening, but a full evaluation? When did anyone formally assess their hearing? These are not optional extras. They are basics that get skipped, and people fall as a result.
This is where families must push the hardest, and where the medical system most often fails older adults.
Medications are one of the most significant and most changeable causes of falls. The Beers Criteria, updated regularly by the American Geriatrics Society, and the STOPP/Frail Criteria were created specifically to identify medications that are high risk for older adults. A pharmacist or physician who actually uses these tools during a medication review can change outcomes. Four medication classes deserve direct, immediate attention:
Blood pressure medications: When blood pressure is controlled too tightly, standing up can cause a sudden, dangerous drop in blood pressure called orthostatic hypotension. The person feels dizzy or lightheaded for a moment, then falls to the floor. The PALTmed Clinical Practice Guideline identifies orthostatic hypotension as significantly associated with falls in older adults and lists antihypertensives among the medications most likely to cause it.
Benzodiazepines (such as lorazepam, diazepam, or temazepam): These medications impair balance and reaction time even at low doses. Their use in older adults substantially raises the risk of falls and hip fractures. They are prescribed for anxiety, sleep, and muscle spasms, often long-term, and they are genuinely dangerous in this population.
Antidepressants (SSRIs, SNRIs, and tricyclics): All three classes are listed in the PALTmed guideline as medication categories that increase fall risk. They can cause psychomotor slowing and ataxia, an unsteadiness in movement that most people do not connect to the pills. Anxiety and depression are not caused by a chemical imbalance in the brain; that theory has been extensively challenged in the medical literature. Antidepressants carry real and serious risks, including serotonin syndrome, a potentially life-threatening condition that can cause agitation, muscle rigidity, and dangerous instability.
Statins: Widely used for cholesterol management, statins carry a recognized risk of muscle weakness and cognitive side effects, both of which directly increase fall risk, particularly in people whose brains or muscles are already under stress.
She was on seven medications. Nobody had reviewed them together in nearly two years. No single pill looked like the problem. But the combination was quietly eroding her balance every time she stood up.
That scenario is not rare. It is common. A thorough medication review, using established clinical criteria, is one of the highest-value actions a family can request.
You Are the One Watching
The doctor had twelve minutes. You have been watching your father for months.
You are the one who noticed the first fall. The second. The shift in his walk. The way he grabs the wall now when he never used to. That observation is not worry or overreaction. It is clinical data, and it belongs in a medical record.
Start a fall log. Write down the date, the time, what your loved one was doing just before the fall, whether they seemed confused or unusually weak beforehand, and what the outcome was. A written record of eight falls over six weeks transforms a concerned family member into an advocate who walks into a medical appointment with evidence that is hard to dismiss.
She brought a handwritten list to the appointment. Twelve falls in eight weeks, each one with a time and a detail about what happened right before. The doctor, who had been about to move on, stopped. Looked again. Ordered a medication review and a urine culture. The answers came quickly after that.
Your observations matter. Bring them.
Do Not Wait for a Diagnosis to Take Action
Falls are serious at any age. Repeated falls are urgent. Whether the cause turns out to be a brain condition, a medication, an infection, or a vision problem, the time to act is now, not after the next fall, and not after a hospitalization.
Four things you can do today:
Start a fall log — write down the date, time, what happened just before, whether confusion or weakness was present, and how long recovery took
Request a full medication review using the Beers Criteria or STOPPFrail, especially if your loved one takes five or more medications; bring the complete list, including over-the-counter drugs and supplements, to every appointment
Insist that infection, vision, and hearing are ruled out before the next appointment ends; do not leave without knowing these have been addressed
Ask for a cognitive screening referral if falls are frequent and no clear cause has been found; a baseline assessment now gives the entire care team a point of comparison if things change
You noticed the pattern. Most people do not look that closely. Now push for the answers your loved one cannot always push for themselves.
Falls are not a small thing. They are the body asking for help. Make sure someone listens.
