Understanding the Different Types of Dementia
Dementia isn’t just one illness — it’s an umbrella for more than a hundred dementia disease types, each affecting the brain in its own way. Knowing the specific dementia type can make a huge difference. It can help you understand certain symptoms, work out what kind of care might help, and feel more prepared for the road ahead.
In this guide, we’ll walk you through the main types — from the four most common, like Alzheimer’s and Vascular Dementia, to some you may not have heard of. By the end, you’ll have a clearer picture of how each type works and what that could mean for everyday life.

How spotting early symptoms and knowing the type of dementia can help
When we hear “dementia,” it’s easy to think it’s just one illness. In reality, it’s a group of conditions that affect the brain in different ways. Knowing which form of dementia your loved one has can help you:
- Make sense of certain symptoms
- Plan ahead for changes
- Find the right mix of care and support
The early symptoms of dementia can be subtle at first — things like forgetting recent conversations, getting mixed up about time or place, struggling to follow conversations, or losing interest in hobbies. It’s easy to put these changes down to “just getting older,” but when they happen more often or start to get worse, they can be an early sign that something else is going on.
While many of these symptoms of dementia can appear across different types, the way they start and progress can vary. For example, some types affect memory first, while others begin with changes in language, movement, or behaviour. Understanding these differences can help you spot patterns sooner, get an earlier diagnosis, and put the right care and support in place before symptoms get worse.
In the sections below, you’ll find the main types of dementia, what often appears first, and how each can affect daily life.
What Causes Dementia and Who’s Most at Risk?
Dementia is caused when the brain is damaged by disease or injury. The exact cause of dementia depends on the specific type, but there are a few things that can increase the likelihood of someone developing the disease.
Some of the biggest risk factors for developing dementia include:
- Getting older (most types are more common over the age of 65)
- A family history of dementia
- Poor heart health — things like high blood pressure, high cholesterol, or diabetes
- Past head injuries
- Certain lifestyle factors, like smoking or heavy drinking
You’ll find the specific causes and risk factors for each common type of dementia in the sections below, as they do vary. That said, being aware of the lifestyle factors in particular that can lead to dementia allows you to make conscious changes to decrease your risk.
The 4 Main Types of Dementia
Alzheimer’s Disease
You’ve probably heard of Alzheimer’s, as it's the most common form of dementia. It often starts with mild cognitive impairment, like little memory slips - forgetting recent chats or misplacing things. Over time, it can affect thinking and behaviour too.
Vascular Dementia
Vascular dementia is the second most common type. It develops when blood flow to the brain is reduced, which can often be after a stroke. The symptoms of vascular dementia can make planning, concentrating, and remembering things more difficult.
Dementia with Lewy Bodies
Lewy body dementia happens when unusual proteins build up in the brain and stop the cells working properly. This can cause confusion, memory lapses, trouble focusing, and sometimes changes in alertness, movement, or even seeing things that aren’t there.
Frontotemporal Dementia (FTD)
Frontotemporal dementia affects the parts of the brain that control behaviour and language. It can cause big changes in how someone acts or speaks, often before their memory is affected.
Alzheimer’s Disease
You’ve probably heard of Alzheimer’s, as it's the most common form of dementia. It often starts with mild cognitive impairment, like little memory slips - forgetting recent chats or misplacing things. Over time, it can affect thinking and behaviour too.
| Forgetting recent events | Build-up of harmful proteins | Age over 65 | Gentle memory activities |
| Getting confused | Affecting brain cells | Family history | Steady daily routine |
| Mood changes | Poor heart health | Emotional support | |
| Everyday tasks becoming harder |
Vascular Dementia
Vascular dementia is the second most common type. It develops when blood flow to the brain is reduced, which can often be after a stroke. The symptoms of vascular dementia can make planning, concentrating, and remembering things more difficult.
| Trouble concentrating | Damage to blood vessels | High blood pressure | Support with daily task |
| Slower thinking | Linked to strokes or poor circulation | Diabetes | Regular health checks |
| Struggling to plan or stay organised | Smoking | Calm and reassuring care routine | |
| Problems remembering recent events | Heart disease or strokes |
Dementia with Lewy Bodies
Lewy body dementia happens when unusual proteins build up in the brain and stop the cells working properly. This can cause confusion, memory lapses, trouble focusing, and sometimes changes in alertness, movement, or even seeing things that aren’t there.
| Visual hallucinations | Protein deposits disrupting brain chemicals | Age over 50 | Keeping a predictable daily schedule |
| Movement problems | Parkinson’s disease | Calming activities like gentle exercise, music, or time outdoors | |
| Sleep disturbances | Family history | Practical help with moving safely | |
| Sudden changes in alertnes |
Frontotemporal Dementia (FTD)
Frontotemporal dementia affects the parts of the brain that control behaviour and language. It can cause big changes in how someone acts or speaks, often before their memory is affected.
| Big changes in personality or behaviour | Damage to the frontal and temporal lobes | Family history | Tailored support to manage behaviour |
| Speaking less or struggling to find words | Genetic mutations | Structured environment to help communication | |
| Acting impulsively or inappropriately | Always ensuring dignity and respect in care |
Rare and less common types of dementia
Mixed dementia: When someone has more than one type at the same time, often Alzheimer’s and Vascular dementia together.
Parkinson’s disease dementia: For some people with Parkinson’s, changes in memory and thinking can develop as the condition progresses.
Alcohol-related brain damage: Caused by long-term heavy drinking, which can lead to memory loss and personality changes.
Huntington’s disease: A rare inherited condition that affects movement, mood, and thinking skills.
Posterior cortical atrophy: A rare form that affects the part of the brain responsible for processing visual information.
Other rarer forms: These can include conditions like Creutzfeldt-Jakob disease, each with its own unique set of challenges.
What the type of dementia means for care
Daily routines
Alzheimer’s and Vascular dementia often respond well to a clear, predictable schedule, with prompts and reminders to help with meals, bathing, or medication.
Behaviour and mood
Frontotemporal dementia can bring major personality changes, while Lewy body dementia may cause sudden shifts in mood or alertness — knowing the cause can make these moments easier to navigate.
Safety and mobility
Lewy body and Parkinson’s disease dementia can cause movement problems, meaning extra care with falls, stairs, and keeping spaces clutter-free.
Communication and relationships
Frontotemporal dementia often affects language skills early, while Alzheimer’s can gradually make conversations harder — patience and simple communication help keep connections strong.
Why understanding the type and symptoms of dementia can help
When you know the type of dementia your loved one has, you can make better sense of their symptoms and the changes you’re seeing. You’ll have a clearer idea of which symptoms of dementia are likely to appear next, how quickly they might get worse, and which care approaches will help most.
This knowledge makes it easier to plan care that suits them, whether that's setting a steady daily routine tor making small changes at home to keep life safe and comfortable. It can also guide conversations with health professionals, helping you get the right support sooner.
With less stress and second-guessing, there’s more space to focus on the moments that matter: a familiar smile, a shared joke, or simply sitting together in peace, knowing you’re giving the right kind of help.
