1.1. Explain what is meant by the term ‘dementia’
Dementia is a set of symptoms that affect the way people think and interact with each other. It is not a disease, but can often be linked to a disease or damage done to the brain. Short-time memory, mind, speech and motor skills are affected. Certain forms of dementia cause a change in the personality of the individual. A person suffering from dementia will lose certain skills and knowledge they already had. This is the main difference to other conditions that affect the mind. People who suffer from learning problems, or lower intelligence will never acquire certain skills, people suffering from dementia will lose skills they have acquired. Dementia is more common in older people. Certain forms of dementia can be treated, to some extent. The most common form of dementia is Alzheimer's disease. 1.2. Describe the key functions of the brain that are – affected by dementia The functions of brain that are affected by dementia are the following: * temporal lobe which is responsible for vision, memory, language, hearing and learning * frontal lobe which is responsible for decision making , problem solving, control over behavior and emotions * parietal lobe which is responsible for sensory information from the body, also where letters are formed, putting things in order and spatial awareness * occipital lobe which is responsible for processing information related to vision * cerebrum lobe which is the biggest part of the Brain, its role is memory, attention, thought, and our consciousness, senses and movement * hippocampus which is responsible for memory forming, organizing and storing thoughts and emotions 1.3. Explain why depression, delirium and age-related memory impairment may be mistaken for dementia Depression, delirium and age related memory impairment are often mistaken for dementia because they show many of the same effects on a persons behavior as dementia. Depression is a mood disorder which brings the individual into intense sadness which affects their daily lives. Depression and dementia have similar affects on the body such as low motivation, apathy, memory problems, slow speech and slow movements. Depression and dementia can coexist.
Delirium is where sudden severe confusion and rapid changes in brain function occur in an individual. The symptoms of delirium such as severe confusion and cognitive impairment can often be mistaken for dementia. Age related memory loss is a part of the normal age process, where individuals struggle to remember information as easily as they used to. Due to dementia symptoms commonly being seen as forgetfulness, age related memory impairment will continue to recognize people, places and objects. They will also not experience the depth of memory loss experienced by a person with dementia.
