What is Dementia?
What is dementia?
What is dementia? Dementia is the term for symptoms that include memory loss and complications concerning thinking, problem solving or language. Best synonym will be “major neurocognitive disorder”.
Initially these symptoms can be small, but eventually they become bad enough to have a detrimental impact on day-to-day life.
Major neurocognitive disorder can be caused by brain damage resulting from diseases such as Alzheimer’s disease or multiple strokes. The symptoms can vary depending on which part of the brain is damaged.
Who is affected by dementia?
Around 850,000 people in the UK were diagnosed with dementia in 2015 of which people over the age of 65 were most affected.
The chance of developing dementia increases with age and in fact 1 in 14 people over 65 have it. However younger people can develop this disorder too and more than 40,000 under 65 develop dementia every year.
What are the symptoms of dementia?
Dementia effects people differently especially within the early stages. However, other factors such as support and domestic environment also play an important role in symptom severity.
Common symptoms affect cognitive functions such as day-to-day memory, concentrating, organisation, language skills, orientation and special awareness.
Mood changes are a common symptom of dementia. Sufferers may feel frustration, irritability, anxiety, and can become easily upset. Hallucination and delusions can also become evident.
Unfortunately the symptoms of dementia are progressive and become worse as time goes by.
It’s common of neurocognitive disorder sufferers to ask repetitive questions and become agitated and restless. In the later stages of dementia physical symptoms such as muscle weakness or weight loss begin to manifest.
What Causes dementia?
Here are a few diseases that can commonly cause dementia.
- Alzheimer disease is the biggest cause of dementia and occurs when abnormal proteins envelop brain cells damaging their internal structure. This causes some cell death and inhibition of electro-chemical signalling between neurons.
- Vascular dementia is caused by brain cell damage or death due to a lack of oxygen to the brain. This can occur in instances of stroke, either on a large scale or numerous smaller strokes.
- Mixed dementia is a combination of two or more types of dementia, usually Alzheimer disease and vascular dementia, where symptoms of both occur.
- Lewy bodies are small structure that form within the brain and cause chemical disruption and cell death. Parkinson’s disease and dementia with Lewy bodies are linked, and as a result, they share some symptoms such as movement difficulties.
- Frontotemporal dementia effects the front and side parts of the brain, as in the case of Pick’s disease. Abnormal proteins forming within the brain cells themselves cause brain cell death, leading to symptoms such as speech difficulties.
What are the stages of dementia?
Dementia is not a disease itself but rather symptoms caused by various diseases. Therefore, symptoms can vary in terms of how they manifest and severity. However, these 5 stages outline can help to evaluate how far the symptoms have progressed.
- Stage 1 – No Impairment. At this stage dementia symptoms are not impairing a persons ability to function in day-to-day life. For example, they have no noteworthy memory loss and regular judgement.
- Stage 2 – Questionable Impairment. Suffers start to get minor impairment including slight memory loss and issues solving problems. They are still able to manage domestic life.
- Stage 3 – Mild Impairment. Short-term memory loss affects day-to-day life noticeably. Loss of orientation and difficulties functioning independently also start to appear.
- Stage 4 – Moderate Impairment. At this stage a sufferer will need help taking care in certain aspects of their life such as hygiene and will need to be accompanied when going out.
- Stage 5 – Severe Impairment. This is the most severe stage where sufferers cannot function on their own. Symptoms include significant memory loss and lack of spatial and temporal orientation
How is dementia treated?
Most cases of dementia cannot be cured; however, there is a lot that can be done to help dementia sufferers. Drugs including donepezil, rivastigmine and galantamine are particularly useful for helping with dementia with Lewy bodies deal with hallucinations and delusions.
Sufferers of vascular dementia are given drugs to help deal with the cause of their symptoms including high blood pressure, high cholesterol, diabetes or heart problems which in turn can help slow the progression of dementia.
Non-medication treatments are also available for dementia sufferers and include support, therapies and activities to help ease the symptoms.
The healthcare professionals provide support to the sufferer and their carer after the diagnosis, allowing them to discuss things such as any questions they may have and what the future holds.
Counselling and therapies help dementia sufferers come to terms with their illness and cognitive behavioural therapy deals with aspects of depression or anxiety.
Staying active is key for people with dementia and activities aimed at keeping the mind active are effective.
Encouraging sufferers to reminisce about their memories is not only for cognitive stimulation but also to enhance their mood in general.
What are the 10 warning signs of dementia?
Dementia is a brain disease that affects memory, thinking, and behavior. It can make it hard to do daily tasks or understand where you are. The Alzheimer’s Association came up with a list of 10 warning signs of dementia that you should be aware of:
- Memory loss that gets in the way of your everyday life.
- Trouble solving problems and making plans.
- Finding it hard to finish things you used to do easily.
- Getting confused about what day or time it is.
- Having problems with your vision, like judging distance or color.
- Having trouble speaking or writing words.
- Misplacing things and not being able to find them.
- Poor judgment, like making bad decisions or spending too much money.
- Not wanting to hang out with friends or do things you used to enjoy.
- Changes in your mood or personality, like feeling anxious, sad, or paranoid.
Remember, just because you experience one or more of these signs doesn’t mean you have dementia. But if you notice several of these signs, it’s important to talk to a healthcare professional. Detecting dementia early can help manage symptoms and improve the quality of life for both the person with dementia and their loved ones.
