UNIT 4222-237 DEMENTIA AWARENESS OUTCOME 1 UNDERSTAND WHAT DEMENTIA IS . 1.1 Explain what is meant by the term ‘dementia’ The word dementia is used to describe a group of symptoms. Although dementia is commonly thought of as memory loss, the reality is much more complex, and symptoms between the different forms of dementia can vary a great deal. Dementia symptoms can include memory loss, confusion and mood changes. 1.2 Describe the key functions of the brain that are affected by dementia. Key functions Parietal Lobe - The parietal lobes have an important role in integrating our senses. In most people the left side parietal lobe is thought of as dominant because of the way it structures information to allow us to read and write, make calculations, perceive objects normally and produce language. Damage to the dominant parietal lobe can lead to Gerstmann's syndrome (e.g. can't tell left from right, can't point to named fingers), apraxia and sensory impairment (e.g. touch, pain). Non-dominant lobe- Non-dominant lobe usually the right side of the brain, will result in different problems. This non-dominant lobe receives information from the occipital lobe and helps provide us with a picture of the world around us. Damage may result in an inability to recognize faces, surroundings or objects (visual agnosia). So, someone may recognize your voice, but not your appearance (you sound like my daughter, but you're not her). Occipital lobe- The occipital lobes of the brain are mainly involved in processing information from the eyes. The ability to see objects is acheived by the eyes, but the ability to make sense of what we see is the job of the occipital lobe. Sometimes damage, or stimulation of the occipital lobes can result in visual hallucinations. For reasons yet to be determined, this area of the brain seems relatively unaffected in dementia. If
