Dementia is a deteriorating condition of the brain. The main symptoms include memory loss, an inability to communicate (a failure to remember the correct words to use for things and names), and mood swings. It is a progressive disease and does not get better. How quickly it progresses does vary in each individual case, it tends to depend on the type of Dementia the person has and on the individual themselves.
Dementia is not a disease in itself; it is a group of symptoms. There are many causes of Dementia; however Alzheimer’s tends to be the most common cause. In the main those who do get Dementia tend to be over the age of 65. This makes it initially quite hard to diagnose, as with age general memory loss and forgetfulness can be common anyway. However if the memory loss and forgetfulness starts happening on a more regular basis this could be the onset of Dementia.
Latter stages of Dementia can be extremely upsetting to the family and friends of the sufferer. The sufferer may no longer recognise them, and not remember who they are. Communication becomes increasingly difficult, to the point where they may not be able to communicate at all. Mobility, appetite, and incontinence are also further complications.
Eventually those suffering from Dementia will need constant care, not least for their own safety.
