This week is Dementia Awareness Week. The Alzheimer’s Society, which is a UK charity, is encouraging anyone concerned to read up and get in touch with them in 2016. Alzheimer’s and Dementia should be talked about and not feared, as catching the symptoms early can have vast improvements on the progression of the condition, and overall quality of life. So we’re explaining what dementia is, the different types of dementia including Alzheimer’s, and the tell tale symptoms to look out for.
As described in the dictionary, dementia is “a chronic or persistent disorder of the mental processes caused by brain disease or injury and marked by memory disorders, personality changes, and impaired reasoning.” Many people use the phrases dementia and Alzheimer’s interchangeably, but this isn’t strictly accurate. Alzheimer’s is the most prevalent dementia condition,with 520,000 people suffering symptoms in the UK, but there are others. Put simply, dementia is a damaging of the brain, leading to a decline in the efficiency of the brain’s functions. This is what gives the most common symptoms of memory loss, confusion and disorientation.
Alzheimer’s is usually present in older patients, as it is quite simply a gradual deterioration of the cells in the brain; proteins build up in the brain and cause gaps between nerve cells, which then eventually die. As well as this, people with Alzheimer’s have a shortage of signal transmitting chemicals, which means the messages are not passed on as effectively as in a healthy brain.
Vascular Dementia is another common disease under the umbrella of dementia, affecting around 150,000 people in the UK This is usually caused following a stroke or series of mini strokes, and causes brain cells to die due to oxygen starvation.
There are many other types of dementia, including fronto-temporal dementia, where the frontal lobe and therefore personality is often more affected, and even prion dementia, where an infectious protein attacks the cells in the brain and kills them.
Symptoms in cognitive illnesses are often harder to spot than physical symptoms, as they affect a person’s mind and can be quite subtle at first. This makes it even more important for you to be alert, and be able to spot symptoms arising and get medical attention. The symptoms are slightly different for different types of dementia, so we will look at the two most common types.
Symptoms of memory loss are usually the earliest symptoms of Alzheimer’s, but others can develop, including:
Although not the main symptoms, other pointers of vascular dementia include:
If you’re concerned about any of the symptoms discussed here, put them into the Isabel Symptom Checker, which works with natural language and free text, and take the finding to discuss with a doctor.
