Is dementia a mental illness? No, it is a condition of the brain. Our brain is our control centre and it controls everything we do and say and think. When the brain is sick we have problems with all our actions, including remembering, speaking, understanding and learning new skills.
In the early stages of dementia you may be able to live at home, continuing to enjoy doing the things you have always done and having an active social life. As the illness progresses, it's likely that you'll need extra help with daily activities, such as housework, shopping and cooking.
People often live for years with dementia. While it can be difficult to think of these diseases as terminal, they do eventually lead to death. Caregivers often experience special challenges surrounding the end of life of someone with dementia in part because the disease progression is so unpredictable.
On average, a person with Alzheimer's lives four to eight years after diagnosis, but can live as long as 20 years, depending on other factors. Changes in the brain related to Alzheimer's begin years before any signs of the disease.
Keeping an active social life, regular exercise, and continuing activities the person enjoys, or finding new ones, can help to reduce behaviours that are out of character. Read more about activities for dementia. Other things that can help include: providing reassurance.
People with dementia can still have nice feelings too. They can feel happy, safe and calm. Some people with dementia may seem like their usual self a lot of the time and you may only notice small changes every now and then. Some people with dementia may not have as many good days.
The average life expectancy figures for the most common types of dementia are as follows: Alzheimer's disease – around eight to 10 years. Life expectancy is less if the person is diagnosed in their 80s or 90s. A few people with Alzheimer's live for longer, sometimes for 15 or even 20 years.
increasing confusion or poor judgment. greater memory loss, including a loss of events in the more distant past. needing assistance with tasks, such as getting dressed, bathing, and grooming. significant personality and behavior changes, often caused by agitation and unfounded suspicion.
Tips for managing dementia end-of-life signs.
These signs may include moaning or yelling, restlessness or an inability to sleep, grimacing, or sweating. This may also signal that it's time to call hospice or a palliative care team to help with the pain management.
Clinicians should be aware of this complication in patients presenting with parkinsonism and autonomic dysfunction, and that sudden death may occur in dementia with Lewy bodies (DLB) as it does in MSA.

Dementia is currently the seventh leading cause of death among all diseases and one of the major causes of disability and dependency among older people worldwide.
In general, once a patient enters the moderate phase of dementia (the phase in which they require some help with their basic activities of daily living like dressing, bathing and grooming), it is unsafe to leave them alone for even short periods of time.
There are many different types of dementia and all of them are progressive. This means symptoms may be relatively mild at first but they get worse with time, usually over several years. These include problems with memory, thinking, problem-solving or language, and often changes in emotions, perception or behaviour.
It is quite common for a person with dementia, especially in the later stages, to spend a lot of their time sleeping – both during the day and night. This can sometimes be distressing for the person's family and friends, as they may worry that something is wrong.
Many people affected by dementia are concerned that they may inherit or pass on dementia. The majority of dementia is not inherited by children and grandchildren. In rarer types of dementia there may be a strong genetic link, but these are only a tiny proportion of overall cases of dementia.
People with dementia may experience physical pain for the same reasons as everyone else. However, because of their declining brain function and abilities, they may be less able to communicate to their carers that they are in pain. This can result in under-treatment of their pain, and reduced quality of life.
Some possible causes include: Autoimmune diseases (conditions that over-activate the immune system) Unusual presentations of more common neurodegenerative diseases (such as Alzheimer's disease) Prion diseases (rare forms of neurodegenerative disease)
There is currently no cure for most types of dementia – including the dementia caused by Alzheimer's disease. These types of dementia are what we call “neurodegenerative.” The progression of these dementias cannot be reversed right now; symptoms gradually get worse.
Middle-stage Alzheimer's is typically the longest stage and can last for many years. As the disease progresses, the person living with Alzheimer's will require a greater level of care. During this stage, the person may confuse words, get frustrated or angry, and act in unexpected ways, such as refusing to bathe.
While most changes in the brain that cause dementia are permanent and worsen over time, thinking and memory problems caused by the following conditions may improve when the condition is treated or addressed: Depression. Medication side effects.
Honesty isn't always the best policy when it comes to someone with Alzheimer's or dementia. That's because their brain may experience a different version of reality. Dementia damages the brain and causes progressive decline in the ability to understand and process information.
Comfort the person with verbal and physical reassurance. Distraction or redirection might also help. Giving your loved one a job such as folding laundry might help to make her feel needed and useful. People with dementia may become uncooperative and resistant to daily activities such as bathing, dressing, and eating.
