Unit 40 - P1 Describe the types of dementia and common signs and symptoms The term ‘dementia’ describes a set of symptoms which can include loss of memory, mood changes and problems with communication and reasoning. These symptoms occur when the brain is damaged by certain conditions and diseases, including Alzheimer’s disease, vascular dementia and Creutzfeldt-Jakob disease. †¨Age is the greatest risk factor for dementia. Dementia affects one in 14 people over the age of 65 and one in six over the age of 80. However, dementia is not restricted to older people: in the UK, there are over 17,000 people under the age of 65 with dementia, although this figure is likely to be an underestimate. Alzheimer’s Disease Alzheimer’s disease†¦show more content†¦The difference between these types depends on what has caused the damage in the brain and which part of the brain has been damaged.†¨Common signs and symptoms of vascular dementia may include: Problems with speed of thinking, concentration and communication. Depression and anxiety accompanying the dementia. Symptoms of a stroke, such as physical weakness or paralysis. Seizures. Periods of severe confusion.

Their presence in the brain disrupts the brain’s normal functioning, interrupting the action of important chemical messengers. Lewy bodies are also found in the brains of people with Parkinson’s disease, a progressive neurological disease that affects movement. †¨Dementia with Lewy bodies isShow MoreRelatedDem 2011002 Words   |  5 Pages4222-237 Dementia awareness (DEM 201) Outcome 1 Understand what dementia is The learner can: 1.
