1.1 Alzheimer's disease is the most common cause of dementia, but there are many rarer diseases and syndromes that can lead to dementia, dementia-like symptoms or mild cognitive impairment. Rarer forms of dementia account for around only 5 per cent of all Dementia is an umbrella term for a range of diseases that affect memory, behaviour and motor skills. The causes vary depending on the disease but largely the presence of "Plaques and tangles" on the neurons of the brain is found in people with Alzheimer's. Plaques are proteins that the body no longer breaks down and allows to build up, these get between the neurons and disrupt message transmission. The tangles are tau proteins within the neurons becoming abnormal. In Korsakoff's, prolonged alcohol abuse is to blame In Vascular dementia, clots and stroke cause abnormal functioning to the affected area of the brain, which is often at the front, above the eyes which effects inhibition and judgement. In Lowy body dementia, abnormal clusters of protein cause Parkinson like symptoms Pick's disease occurs after trauma to the front section of the brain, starting out with personality and behaviour changes and followed by memory loss while dementia isn't necessarily hereditary, if a parent has it a child is more likely to develop it. 1.2 Dementia is a condition of the brain which causes a gradual loss of mental ability, including problems with memory, understanding, judgement, thinking and language. In addition, other problems commonly develop, such as changes in personality and changes in the way a person interacts with others in social situations. As dementia progresses, a person's ability to look after themselves from day to day may also become affected. There are various causes of dementia. Some memory loss as we age is normal, but the kind of memory loss associated with dementia is more severe 1.3People with dementia often confuse the generations mistaking their wife for their mother, for example. This may be very distressing for their loved ones, but it's a natural aspect of their memory loss. The person with dementia may be trying to interpret a world that no longer makes sense to them because their brain is processing information incorrectly. Sometimes the person with dementia and those around them will misinterpret each other's attempts at communication. These misunderstandings can be difficult, and may require some support. Difficulties with communication can be upsetting and frustrating for the person with dementia and for those around them, but there are lots of ways to help make sure that you understand each other 1.4Everybody forgets things from time to time. In general, the things that you tend to forget most easily are the things that you feel do not matter as much. The things that you tend to remember most easily are the things that are important to you - for example, a special birthday. However, some people just seem to have a better memory than others, and some people are more forgetful than others. They can include the following.
If your concentration is poor then you do not notice things as much, and do not retain things as much as you would normally. Poor concentration can be a result of simply being bored or tired. However, it can also be a symptom of depression and anxiety. Depression As well as poor concentration, some people with depression also have slowed thinking. This can cause memory problems until the depression clears. Do tell a doctor if you think that you are depressed, as treatment often works well. Other symptoms of depression include: a low mood for most of the time; loss of enjoyment and interest in life; abnormal sadness; weepiness; feelings of guilt or being useless; poor motivation; sleeping problems; tiredness; difficulty with affection; poor appetite; being irritable or restless.
If you feel ill, this can affect concentration and memory....
