How fast dementia progresses will depend on the individual person and what type of dementia they have. Each person is unique and will experience dementia in their own way. 2) Describe the key functions of the brain that are affected by dementia: The key functions that are affected by dementia are: * Temporal Lobe – Responsible for vision, memory, language, hearing and learning. * Frontal Lobe – Responsible for decision making, problem solving, control behaviour and emotions. * Parietal Lobe – Responsible for sensory information from the body, also where letters are formed, putting things in order and spatial awareness.
People with lewy bodies often suffer hallucinations. Frontal lobe dementia Frontal lobe dementia including Picks disease , in this form of dementia damage to9 brain cells is more localised than in Alzheimers disease , usually beginning in the front part of the brain . Initially personality and behaviour are more affected than memory but in later stages symptoms are similar to Alzheimers. An early sign that someone's language is being affected by dementia is that they can't find the right words – particularly the names of people. The person may substitute an incorrect word, or may not find any word at all.
Dementia is a collection of symptoms including memory loss, personality change, and impaired intellectual functions resulting from disease or trauma to the brain. These changes are not part of normal aging and are severe enough to impact daily living, independence, and relationships. There will likely be noticeable decline in communication, learning, remembering, and problem solving. These changes may occur quickly or very slowly over time. Common signs and symptoms of dementia include: * Memory loss * Impaired judgment
Memory is the cognitive process of encoding, storing and retrieving information (Melton 1963) and is also involved in processing vast amounts of information (McLeod, S. A. 2007). Memories could be reliable, as some people are able to hold very vivid details of events in their activated schema. However, the retrieval of memory could be subjected to the change over time through reconstruction and therefore questions the reliability and accuracy of the information recalled. The reliability of memory could be demonstrated by outlining how the encoding and retrieval of memory could be susceptible to reconstruction.
Neurons and synapses become damaged by dementia they may be unable to carry messages that tell a section of the brain what to do. 1.2. Describe the key functions of the brain that are affected by dementia Frontal lobe - Movement, emotional behaviour, personality, interpretation and feeling. Parietal lobe - Language, special awareness and recognition. Temporal lobe – Long term memory, speech and hearing.
Amnesiac patients have been instrumental in generating this new understanding of human memory, and have also allowed researchers to pinpoint, with varying degrees of precision, the anatomical regions of the brain that are associated with specific aspects of the memory process. In this article I intend to provide an overview of the current state of knowledge regarding the human memory system, including, as far as is possible based on current literature, memory's constituent processes, their neurological substrates, an overview of amnesia, as well as a section on some of the practical concerns involved in memory assessment within the context of a
It sounds simple, but when you break the process down it becomes much more complicated. In this paper we will discuss four different types of learning. We will also evaluate the rules of conditioning, reinforcement, and punishment throughout the learning process. We will describe how the memory is formed and analyze the relationship that the memory has with learning. Understanding the learning process and how it is stamped into the memory is paramount while attempting to learn or teach others.
Can we make people believe things that did not happen? Can we change their memories? This paper will review research regarding the influence of misinformation on memories. There are different variables which determine how great the misinformation effect is. These variables are timing, repetition, and framing.
Associations, different memory elements and distortions, the brain itself, Presque and Jamais vu, and past experiences are all some of these factors that play key roles in déjà vu experiences. It’s said that history repeats itself and this could be why sometimes settings and situations feel familiar and one may associate that as déjà vu. How people register information in their brains is another reason déjà vu feels so real, mainly because when an event is taking place people tend to remember what was going on instead of how, when, where, and who is there at that time. So when something similar happens one can only recall what was going on and seem to forget who, when, where, and how it happened leading them to believe it hasn’t happened before and they know exactly what’s about to happen. This is where many are confused about what déjà vu really is.
Emotions define who we are to ourselves, as well to others. They are the central core of psychiatric disorders and can change our physical well-being. Emotional experiences can leave strong traces in the brain, either good or bad. Scientists once thought that memories would only go to one system in the brain. But they have discovered that there are various ways for memories to be formed.
