Frontotemporal Dementia and Phone Calls

How FTD differs from Alzheimer's in phone behaviour

Frontotemporal dementia damages the frontal and temporal lobes first. Those regions govern personality, behaviour, emotional regulation, and language. Alzheimer's typically begins with short-term memory loss, which is why so much of the public conversation about dementia centres on forgetting names and missing appointments. FTD often begins somewhere else entirely. The first signs are personality changes, disinhibition, apathy, compulsive behaviours, and a slow erosion of language.

The phone calls reflect those differences. A person with FTD may call with an emotional intensity that feels out of proportion, or with a flatness that feels equally unfamiliar. Language can be impaired in distinctive ways, including word-finding difficulties, perseveration on a single phrase, or repeating the same topic across many calls in a single afternoon. Some FTD presentations produce the same anxiety-driven repetitive calling that families with Alzheimer's see. Others produce a different texture entirely, with an urgency or emotional quality that is harder to explain to relatives who have never encountered FTD before. None of these patterns mean the call is meaningless. They are the symptoms speaking.

The anxiety underneath FTD calls

For all the differences in how FTD presents, the engine driving repetitive calls is the same as in Alzheimer's. It is dementia separation anxiety. The familiar voice of the primary caregiver is the most consistent emotional anchor the brain still has access to. When my mother Sharon calls me, she is not always reaching for information. She is reaching for the person her brain most associates with safety and continuity.

FTD changes how that reaching sounds. The words may be different. The tone may be sharper, or duller, or stuck on a phrase she said an hour ago. The need underneath the words is the same need any person with dementia has when they pick up the phone. They want to hear the voice that settles them. Once you hold that frame, the calls become easier to interpret. A call that sounds frustrated or strange is not a call that means something different from the calm calls. It is the same call routed through a brain that no longer regulates emotion the way it used to. Knowing that does not make the calls less hard. It makes them less confusing.

What the Alzheimer Society of Canada says about FTD communication

The Alzheimer Society of Canada's communication guidelines for dementia care apply to frontotemporal dementia as much as they apply to Alzheimer's. Warmth, patience, meeting the person where they are, no corrections, no quizzing. The principles do not change with the subtype because the underlying need does not change with the subtype. Validation therapy, often simply called validation therapy in clinical settings, is the standard in memory care worldwide, is the appropriate framework for FTD calls because it does not engage with the literal content of the call. It engages with the emotional need underneath it.

For FTD specifically, two adjustments help. Keep calls short, because longer conversations often outpace the language processing the person can sustain. Keep them warm, because the emotional channel often remains intact when the verbal channel is faltering. A short, warm call resolves the need. A long, explanatory call usually does not.

The research on familiar voice support

The most recent randomised controlled trial on simulated presence therapy (PubMed 38646703) found meaningful reductions in anxiety and agitation when people with dementia were given access to familiar voice support during periods of distress. The trial's population included a range of dementia subtypes, including frontotemporal presentations. The familiar voice works because it speaks directly to the emotional need, regardless of which lobes the disease has damaged. The mechanism is the same one any FTD family has watched in the living room. The voice arrives, the person settles, the call ends.

KindredMind and FTD, built from this experience

I built KindredMind with my co-founder Patrick Armstrong because my mother Sharon has frontotemporal dementia, and the available tools did not address what Sharon actually needed. Most products in the dementia space are designed around Alzheimer's prompts and reminders, which assume a memory-loss-first presentation. FTD is not that. We needed something built for the call itself, not for the calendar.

KindredMind is an voice companion for dementia families. It answers calls in the family caregiver's voice, drawing on a personalized knowledge base the caregiver builds, following the Alzheimer Society of Canada's published communication guidelines for dementia care. It works for FTD families where the person still initiates phone calls independently, which covers most mild to moderate FTD presentations. About 90% of calls resolve in the first conversation, because the person reaches for the phone, hears the voice they were reaching for, and gets the warmth they needed. They do not get information they cannot hold or corrections they cannot use. They get what their brain was actually asking for.

What makes FTD phone calls different from Alzheimer's calls

If you have spent any time in dementia caregiver groups, you have probably noticed that the calls people describe sound very different depending on the disease. Alzheimer's calls tend to follow a recognisable rhythm. The same gentle question asked again and again, often with a softness in the voice, a confusion that lands as something almost childlike. Where are you, when are you coming, did I eat. The question loops because the memory of asking it does not survive long enough to break the loop. The emotional tone of the call is usually pleading or worried, but rarely combative.

FTD calls land differently because the disease itself is different. Frontotemporal dementia attacks the frontal and temporal lobes first, which means it attacks behaviour, personality, language, and emotional regulation before it touches memory in any meaningful way. The person calling you may still know your name, may still know where they are, may even still remember that they called an hour ago. What has shifted is the brake. The part of the brain that normally holds back a feeling long enough to choose how to express it is no longer doing that work. So the feeling lands on the call, raw, with very little distance between what they are feeling and what comes out of their mouth.

The result is calls that often feel more emotionally intense than Alzheimer's calls. There is more anger sometimes, more frustration, more confusion that has an edge to it. A loved one with FTD might call to tell you that something is wrong, and the something can shift mid-sentence from a real concern to a fixation that did not exist a minute ago. They might call to accuse, to demand, to insist on a version of events that does not match what is actually happening. They might call sounding fine and then become distressed within thirty seconds because a small thing tipped them.

The other shift is language. Many FTD subtypes affect the language network directly. Words come slower, or in the wrong order, or with the wrong word substituted for the right one. The frustration of not being able to find the word often becomes part of the call itself. The caregiver on the other end is then doing two jobs at once, holding the emotional weight of the call and trying to translate what is actually being asked. Both jobs are exhausting. Neither resolves through reasoning.

Understanding this difference matters because the standard Alzheimer's advice does not always fit. Telling an FTD family to use distraction, gentle redirection, and short reassuring phrases is not wrong, but it underestimates what they are working with. The behavioural and emotional intensity of FTD calls needs a different posture. Less explaining, more steadying. Less correcting, more letting the wave pass. The underlying need is still dementia separation anxiety finding the only outlet it has, but the surface of the call looks different and feels different and asks something different of the person answering it. KindredMind addresses FTD-specific call patterns directly, answering in the caregiver's cloned voice with consistent, calm, validation-based responses that meet the behavioral distress driving the call, not just the memory loss.

What I learned from Sharon's calls

My mother Sharon has mixed dementia. The clinical picture is vascular dementia and frontotemporal lobe dementia, amplified by a stroke that took something away from her that she never fully got back. The mix matters because it shapes the calls. The vascular piece brings step-change worsenings. The frontotemporal piece brings the behavioural and emotional intensity I described above. The stroke layered language difficulty on top of both. Most of what I learned about FTD calls, I learned from the years of phone calls with her.

The first thing I learned is that the timing of the calls is information. Sharon's hardest calls were almost never random. They came in clusters, usually around transitions in her day. After waking. Before a meal. After staff changeover at her facility. Late afternoon as the light shifted. Once I started writing down the times, the pattern was unmistakable. The brain, with less capacity to hold itself together through change, reaches for the most stabilising voice it knows, and for Sharon that voice was mine. The calls were not interruptions of her day. They were her brain trying to reset itself by reaching for the person who feels safe.

The second thing I learned is that explanations almost never helped. If I tried to explain that I had already visited that morning, or that the person she was upset about had not actually said the thing she remembered them saying, the call would get worse, not better. The frontal lobe damage meant my logic was landing in a place that could not use it. What worked was warmth without content. Saying her name. Saying I was glad she called. Asking about the small concrete thing right in front of her, the cup of tea, the cardigan, the bird outside the window. The call would settle, and within a few minutes she would be telling me about something completely different, and the call would end with both of us laughing.

The third thing I learned is that the same call could not be answered the same way every time. With Alzheimer's, the documented pattern is that consistent gentle responses tend to soothe consistently. With FTD, the response that calmed Sharon on Monday might escalate her on Wednesday because the disease was in a different state on Wednesday. I had to read the call as it was happening, not as I expected it to be. The Alzheimer Society of Canada communication guidelines were the foundation, the warmth and validation and not correcting, but the application of those principles had to flex with what Sharon was actually presenting in that moment.

The fourth thing I learned is the one that built KindredMind. The pattern was bigger than me. I could not be the voice that picked up every time, especially at night, and the calls that went to voicemail did not resolve. The anxiety that drove the call did not get answered, and that anxiety would feed the next call. What Sharon needed was a familiar voice on the other end of every call she made, not a recording, not a stranger, not silence. That is the gap KindredMind was built to close, and Sharon's calls are the reason every design decision in the product is what it is.

How KindredMind handles FTD-specific call patterns

KindredMind is built on validation therapy and on the principles behind simulated presence therapy, and that foundation is what makes it fit FTD calls in particular. Validation therapy does not engage with the literal content of the call. It does not try to correct, reorient, or explain. It meets the emotional state the caller is in and steadies it with warmth and familiarity. For an FTD caller whose frontal lobe damage has stripped away the brake between feeling and expression, this is exactly the posture the call needs. The call does not require a solution. It requires a voice that is unbothered by the intensity, that does not match the escalation, and that gently leaves space for the wave to pass. Because FTD calls are driven by behavioral distress rather than memory loss alone, consistent, calm responses in a familiar voice are especially important — KindredMind's validation-based approach addresses this directly.

Where Alzheimer's calls tend to settle through gentle repetition of the same reassuring information, FTD calls more often settle through tone. KindredMind's voice is the caregiver's own voice, which means it carries the relational history that the FTD brain still recognises even when language is failing. The knowledge base the caregiver builds during setup is also tuned for FTD families. It captures the person's daily routine, the people they trust, the topics that calm them, and the topics to steer away from when distress is high. None of that depends on the caller remembering the previous call. The companion meets them where they are, every call, in the voice they need to hear.

The practical effect for FTD families is that the calls that used to require the caregiver to be present, alert, and emotionally available at any hour can now be answered consistently in the caregiver's voice without the caregiver carrying the weight of every one. The caller still gets the warmth their brain is asking for. The caregiver gets to sleep, to work, to be present with their own family, and then to choose when to be on the call themselves. The relationship survives, because the calls stop draining it.

The questions FTD families ask me most

Since launching KindredMind, I have spent hundreds of hours on the phone with other FTD families. The questions repeat, and the questions are not the same questions Alzheimer's families ask. I want to put a few of them on this page directly, because if you are reading this you may be looking for one of these answers right now and you may not have anyone in your life who can give it to you with any confidence.

The first question is whether the calls are going to get worse. The honest answer for FTD is yes, then no, then differently. There is usually a window in mid-stage FTD where the calls intensify because the behavioural symptoms are at their loudest and the language is still functional enough to drive the call. As the disease progresses further, the calls often slow, not because the underlying anxiety is gone, but because initiating a call requires a sequence of actions the brain can no longer reliably string together. The hardest stretch is usually the middle. If you are in it, please know that the volume of calls in mid-stage FTD is not a reflection of how much you are doing wrong. It is a reflection of where the disease is in its arc.

The second question is whether their loved one knows what they are doing when they call upset. The answer I give, gently, is that knowing is not the right frame. The part of the brain that holds intent and self-awareness is one of the parts the disease damages first in FTD. They are not choosing to call you in distress. They are not making a decision to escalate. The behaviour is the disease, in the same way a tremor is the disease in Parkinson's. Holding this in mind does not stop the calls from being hard. It does change what they mean.

The third question is whether they should keep answering at all. This one comes from caregivers who have hit a wall and need permission to stop picking up every call. The answer I give is that the calls do need to be answered, by something or someone, because unanswered calls drive the next call and the one after that. But the caller does not need to be answered by you, in real time, every single time. The mechanism that resolves the anxiety is a familiar voice, not specifically your voice in the present moment. This is the finding that thirty years of simulated presence research has confirmed and that families discover for themselves when they hear how a recording of their own voice settles their loved one. You can build the system that answers the calls and still be the person on the other end when you choose to be.

The fourth question is whether KindredMind will recognise that something is genuinely wrong, an emergency, a fall, a medical event. The answer is that the companion is built with safety language detection that flags real-world warning signs, including language consistent with falls, medical distress, and clear emergencies. When those signals appear, the call routes to the caregiver and the caregiver gets a real-time alert. The companion is not a substitute for emergency response. It is a layer that handles the much larger volume of calls that are not emergencies and that escalates the calls that are.

The fifth question, and the one that asks the most of me when I answer it, is whether using a voice companion is honest. Whether their loved one would feel deceived if they understood. The version of this answer I give now, after years with Sharon and after thousands of calls, is that the part of the brain that would feel deceived is not the part of the brain that is on the call. The part of the brain that is on the call is the part that needs warmth and a familiar voice and the feeling of safety. That part gets exactly what it needs from a companion built in the caregiver's voice. The conversation about consent and ethics belongs upstream of the call, with the family, with the care team, in the choices made about how to set the system up. We have written about how we think about that on our ethics page, and the conversation is one I welcome from any family considering whether this is right for them.

What I would tell you if we were sitting at the kitchen table

If you are an FTD caregiver reading this page late at night, between calls, with the phone face down on the counter and a knot in your chest, I want to say a few things directly to you that I would say if we were sitting at my kitchen table with cups of tea.

The first is that the version of this you are living is harder than the version most of the people in your life understand. FTD is not the dementia people picture when they hear the word dementia. There is no public language for what FTD does to a personality, to a relationship, to the years between diagnosis and the end. When friends ask how your parent or partner is doing, the honest answer does not fit the shape of the question they are asking. You end up giving the short, softened version that lets the conversation continue, and then you carry the rest alone. That carrying is real. It is the part nobody can see, and it is the part that builds up.

The second is that the calls are not a measure of how much your loved one loves you, or how much they need you, or how much they trust you. They are a measure of where the disease is in their brain. A day with twenty calls is not a day where they need you twenty times. It is a day where the disease is loud. A day with two calls is not a day where they have stopped reaching for you. It is a day where the disease is quieter or where their initiation has slowed. Reading the calls as messages about your importance to them will burn you out. Reading them as readouts on the disease will not.

The third is that you are allowed to build a life around this disease without sacrificing all of yours to it. The caregivers who survive FTD without losing themselves are the ones who set up systems, accept help, use whatever tools genuinely work, and stop trying to be the only line of defence between their loved one and the disease. KindredMind is one of those systems. There are others. The point is to build them, not to keep promising yourself you will white-knuckle through the next month.

The fourth is that the relationship with your loved one is still there, underneath the disease, and the parts of it that have not been taken can still be tended. Sharon and I still laugh on calls. Not every call. Not even most calls. But often enough that I know the relationship is not gone, even on the days when the disease has been very loud. The voice companion did not replace the calls where we still find each other. It cleared space for those calls to happen, by absorbing the calls that were costing me the energy I needed to be present in the ones that mattered.

The fifth, and the last thing I will say on this page, is that you are doing this. Whatever you are managing right now, you are managing it. The fact that you are looking for information about FTD phone calls at all is evidence that you are still showing up for someone who needs you. I am sorry the disease is what it is. I am glad you are looking for tools. I built KindredMind so that families like ours would have one more tool that actually fits the shape of what we are living. Whatever you choose, I hope you find some relief tonight.

The practical setup that worked for us

I want to close with the practical version of what worked for our family, because the abstract advice in dementia caregiver guides rarely translates cleanly into a Tuesday afternoon. This is the setup we landed on with Sharon, and it is the setup most FTD families I talk to end up with too, in some shape.

The first piece is a single dedicated phone number that lives in their contacts under your name. Not a redirected line, not a forwarding rule. A number they can dial directly, that always picks up, that always sounds like you. For Sharon, the moment she could press one button and hear my voice no matter what time she called, the panic spiral that used to build between dialling and connecting stopped happening. The certainty of the answer mattered as much as the content of the answer.

The second piece is a knowledge base that the caregiver actually invests time in building. The temptation when you are exhausted is to fill it in quickly and move on. The families who get the most out of KindredMind are the ones who treat the knowledge base like a living document. They add the daily routine, the family members and how they are referred to, the favourite stories, the topics that calm, the topics to steer away from when distress is high, the small specific things that anchor the person to who they are. The richer the knowledge base, the more the calls feel like a real conversation rather than a generic warm response. For Sharon, putting in the names of her childhood pets and the specific way she likes her tea made calls noticeably better. The companion is only as warm as the material the caregiver gives it to work with.

The third piece is honest expectations about what the first week will look like. The first call your loved one makes to a voice companion may not be a great call. They may notice that something is slightly off. They may push back on the conversation in a way that feels awkward to read in the transcript afterwards. By the third or fourth call, the brain has updated its prediction of what to expect from this number, and the calls settle. Most of the families I have worked with describe the same arc. A bit strange at first, then very normal, then a relief. Knowing this in advance means you do not panic at the first imperfect call and pull the plug before the system has had a chance to settle in.

The fourth piece is using the call summaries the way they are intended to be used. After every call, the caregiver gets a transcript and a short summary. The summary is not just a record. It is a window into how your loved one is actually doing day to day, in the language they are using, on the topics they are returning to. Patterns surface that you would not have seen if you had only spoken with them directly, because you would have been managing the call rather than reading it. Sharon's summaries told me when something was shifting before her care team noticed. I started bringing the patterns to her medical reviews, and they changed conversations with the clinical team in ways that helped Sharon directly.

The fifth piece is letting yourself rest. Once the system is in place, the hardest part for many caregivers is allowing themselves to put the phone down. The reflex to pick up every call has been built in over years of being the only line. Letting the companion answer the calls that the companion is good at answering, and saving your own attention for the calls you actually want to be on, takes practice. It is also the entire point. The calls do not stop being important. You stop being the only one carrying them, and that change is what makes the rest of caregiving sustainable.
