The ways your eyes warn you that dementia is forming are through vision problems like blurry vision, loss of peripheral vision or difficulty with depth perception which can indicate you have dementia or are getting dementia.
With dementia you may also have difficulty reading, writing or understanding symbols or numbers.
People with dementia may also have visual hallucinations and see things that are not there and can be an early sign of dementia.
With dementia you may also have impaired visual memory and not be able to recall faces, objects or places.
A person with dementia sometimes but not always knows they have it.
In the early stages a person may know they have dementia, although many dementia patients may deny they have dementia or deny they are experiencing difficulties and is a psychological reaction which helps them to cope with difficult emotions.
People with dementia may also not recognize changes in their emotions and behavior and it's caused by physical changes in their brain.
The signs that dementia is getting worse are problems in memory and decision making, difficulty in communication, difficulty with tasks such as using a TV, bathing, showering, getting dressed paying bills etc.
Other signs that dementia is getting worse include increased frustration, increased anxiety , increased agitation, increased confusion suspiciousness, sadness and depression.
A person that has dementia that is getting worse can also experience hallucinations, seeing other people or objects that are not there and becoming more aggressive, lose their appetite, weight loss, loss of bladder control, increased falls, difficulty walking and keeping balance.
The causes of dementia to worsen are changes in the brain and chronic stress, routine changes to a persons routine.
Chronic stress in dementia can worsen dementia and cause memory problems, fainting, dizziness, depression and anxiety.
Other things that can make dementia worse are certain medications, brain injury, cancer or prion disease, lung and heart conditions which restrict the blood supply and oxygen to the brain and even infections or surgery.
As the dementia progresses in the brain it naturally gets worse as time goes by.
The reason dementia gets worse at night is because of sundowning, which is when symptoms of dementia like anxiety, agitation and confusion worsen as the daylight fades away.
The sundowning in dementia is often caused by fatigue from the day, low lighting, difficulty differentiating reality from dreams and disrupted circadian rhythms.
The dementia symptoms can be exacerbated by darkness and also the unfamiliar environment of nighttime.
Low lighting also can increase shadows and can cause the dementia patient to become confused by what they see and they may hallucinate and become increasingly agitated.
Most people with dementia also sleep a lot, especially in the later stages of dementia.
As dementia progresses the persons brain becomes more damaged which makes it harder to perform simple tasks such as understanding what is going on, communicating and eating which can be exhausting and lead to more sleep.
Dementia also makes it difficult to regulate the persons energy levels and can lead to excessive sleeping.
People with dementia often also take medications like antidepressants, antihistamines and antipsychotics can cause drowsiness.
Dementia patients also often experience other sleep problems which include restlessness, irritability and confusion as daylight begins to fade, napping a lot during the day and waking up many times during the night.
A person with dementia can live at home until they die although they often will need at home care if they remain at home.
In some cases the person may need to be moved into a care home if they become dangerous to themselves or others.
People that have dementia should not live alone at home without any care as they are suffering from cognitive impairment which can lead to them coming to any harm.
If the person that has dementia is no longer able to manage at home as well as they used too and are becoming a danger then they should be put in a home or have at home 24 hour care.
If the dementia patient is no longer able to do any daily tasks, such as eating, bathing, showering, using the toilet, without help from another person or the dementia patient keeps having falls then it's time to put the dementia patient in a nursing home.
Dementia can cause a reduced ability to distinguish colors and can lead to mismatched clothing as well.
Other vision problems that dementia can cause are retinal changes, slower and erratic eye movements, difficulty in processing visual information from both eyes, difficulty in recognizing faces, reduced sensitivity to contrast and difficulty detecting movement.
Dementia can also affect how a persons brain is able to process visual information and neural degeneration can also affect the parts of the persons brain which process eyesight.
Dementia is not often inherited although if someone in your family has had or has dementia then it's possible that you too or someone else in the family could get dementia.
In rare cases, dementia can be caused by genetic mutations that are inherited.
For example a dementia called familial frontotemporal dementia is caused by a single faulty gene which is passed down from a parent to a child and in this case the child has a 50 percent chance of inheriting the gene and then developing dementia later in life.
However the majority of dementia cases are not inherited by grandchildren and children or parents to child.
The stage of dementia that is anger is the middle stage although anger in dementia can also occur at any stage during dementia.
Anger in dementia patients is often a reaction to frustration and confusion that is experienced in the later stages of dementia.
However there really is no specific angry stage of dementia but the anger often occurs in the middle to late stages of dementia.
The seven stages of dementia are.
Stage 1 dementia with no cognitive decline.
Stage 2 dementia with very mild cognitive decline.
Stage 3 dementia with mild cognitive decline.
Stage 4 dementia with moderate cognitive decline.
Stage 5 dementia with moderately severe cognitive decline.
Stage 6 dementia with severe cognitive decline.
Stage 7 dementia with very severe cognitive decline.
In dementia the stages of dementia are not always linear and some people may experience different paths as they go through them.
Some people with dementia experience periods of decline that is followed by periods of stability.
The symptoms of dementia and patterns of progression of the dementia, also vary depending on the type of dementia that the person has.
The most common type of dementia is Alzheimer's.
A person with dementia will often need to be put into a care home when they are no longer able to do daily tasks, like eating, without the support of another person.
Or if the person with dementia is no longer safe at home like they start fires or they keep having falls.
Dementia is a condition which causes a decline in a persons mental abilities like remembering, reasoning and thinking which interferes with daily life.
Dementia is caused by the death of the nerve cells in the brain and is more common as you age.
Dementia though is not actually a normal part of aging and many people live well into their 90s and above without getting dementia.
The most common types of behavioral triggers in dementia patients are confusion, pain or discomfort, and a changing or overwhelming environment.
