1.2: Describe the types of memory impairment commonly experienced by individuals with dementia.
There are different types of memory impairments. Sensory memory, long term memory and short term memory. Down below I will be explaining what these memories are;
Sensory memory: is one of the five human sense e.g. vision, touch, smell, hear and taste. These are the senses that are connected to our nervous systems and brain. The brain receives information and processes it, this happens rapidly, half of the sensory neuron that is liable for processing visual information, part of the brain is responsible for processing it.
Short term memory: is accountable for starting information for short amount of time like 10-15s. time it decides to remove or move
While the average life expectancy of the world’s population has increased, the number of detected dementia cases has commensurately risen to astonishing levels. Along with improved discovery of this disorder, new causes and treatments have been found, from which many innovative techniques have been developed towards the prevention of future incidences and reduction of the effects of this condition; however, the quest for these solutions have raised more questions than it has answered. Why do some develop this disorder, while others do not? Can early detection be achieved to reverse the processes or limit its effects? Further specifics on these topics have been categorized into three main sections, which include:
People with dementia may have problems with short-term memory, keeping track of their belongings, keeping up with plans, remembering appointments or travel dates. Many dementias are progressive. This means that symptoms start out slowly and gradually get worse with time. Alzheimer’s and other types of dementia are diagnosed based on careful medical history, a physical examination, laboratory tests, and the characteristic changes in thinking, day-to-day function and behavior related to each
Memory is an important and active system that receives information. Memory is made up of three different stages sensory memory, short term memory, and long term memory. According to the power point presentation, sensory memory refers to short storage of memory that allows an individual to process information as it occurs. Short term memory refers to memory that is only available for a limited time. It is information that is held for seconds or sometimes even minutes. Long term memory refers to memory that is stored for a long period of time and it has an unlimited capacity with the ability to hold as much information as possible. Retrieval is key and it allows individuals to have memories. Episodic memory refers to memory for events that we
The first stage of memory is the sensory memory. Sensory memory holds sights, sounds, smells, textures, and other sensory impressions for only a few seconds, and it operates on an unconscious level. (Zimbardo, P., & Johnson, R. (2013). Memory. In Psychology: Core Concepts With Dsm-5 Update (pp. 177-179). Pearson College Div.)This stage of memory is the shortest element of memory. Sensory memory has the ability to retain impressions of different sensory information. Sensory memory is the ultra-short term memory and it retains brief impressions of the sensory stimuli after the stimulus has ended. It holds the shortest impression of sensory information and even when the sensory system does not send information the sensory memory still holds the shortest impression. There are many different issues and characteristics of the sensory memory; it has a high capacity to form memory registration of visual data, and the information that’s stored is un-interpreted, and the it the visual information fades away after less than a second. In order to use the information in your sensory memory, you must encode the information quickly. The sensory memory is the hardest memory to grasp and most of what we sense is forgotten. Sensory memory allows the eye to have a larger field of vision by remembering images that your eye has already focused on. The sensory memory, in general, allows us to maintain incoming sensory information long enough for us to screen it and determine if it is important. (Zimbardo, P., & Johnson, R. (2013). Memory. In Psychology: Core Concepts With Dsm-5 Update (pp. 177-179). Pearson College Div.)
Memory is a group of related mental processes that are involved in acquiring, storing, and retrieving information (Hockenberry and Hocenberry page 232). I will be addressing two specific types of memory: short-term memory and long-term memory. Short-term memory holds temporary information transferred from sensory memory or long-term memory. Sensory memory is the first stage of memory and obtains information for a brief amount of time. Short-term memory is also called active memory and is stored in the prefrontal cortex which is the most active part of the brain during an activity. Short-term memory can hold information for roughly twenty seconds, but sensory memory holds information for a shorter amount of time. We usually store things such
Email, lettre, disc... The memory acts in the same way and info are supported by specific codes: sensorial codes, motor codes and symbolic codes. A special memory exists to each different info: tactual, visual, auditory and olfactory but these codes don’t have the same importance. Visual and auditory codes are the most important codes because they are the primary means of language in the memory. The auditory code is concerned with longer times than the visual one. (You remember longer a sequence of letters if you hear them than if you see them).
Delirium, Depression, and Dementia are some of the most common psychological diagnoses in the elderly today. The three D’s are difficult to differentiate between in older adults because they overlap with each other and can all exist in the same patient at once. Delirium, Dementia, and Depression all affect the elderly’s quality of life and often increase the risks for one another (Downing, Caprio & Lyness, 2013). For the purpose of this paper I will be focusing primarily on the diagnosis of Dementia, the prevention, and nursing measures associated with it, but first I would like to differentiate between Delirium and Depression because Dementia is often associated with the two in the older adult population.
Memory encompasses information that has been learned and stored over a period of time. Once an event is stored in our memory it can be readily retrieved. Amnesia occurs when there is partial or complete memory loss. There are two types of memory loss: anterograde amnesia and retrograde amnesia—which can be a result of either an organic cause, damage to the brain by physical injury; drug usage; mental disorders; or post-traumatic stress (Mastin).
In the sensory memory is the information that is given to a person by their senses, i.e. what a person feels, hears, tastes, smells or sees is stored within this memory. Any information stored within this memory on...
Perception, at most times, is a credible way to assess the world around us. Without perception, we would not know what to do with all the incoming information from our environment. Perception is constructed of our senses and the unconscious interpretations of those sensations. Our senses bring in information from our environment, and our brain interprets what those sensations mean. The five most commonly accepted senses -- taste, smell, hearing, sight, and touch -- all help create the world around us as we know it.
Introduction This assignment critically discusses dementia, a widespread disability among older adults today. It provides an introduction to dementia and analyses its prevalence in society. The various forms of dementia are elaborated with descriptions of dysfunctions and symptoms. Nursing Assessment and Interventions are provided in the further sections which discuss actions nurses should take while evaluating patients and treating them.
The five types are Memory is classified by a few different characteristics. Declarative Memory is the memory of dates, historical facts, and telephone numbers (Silvia Cardoso). It is easier to build up Declarative Memory but can be easily forgotten as well. Procedural Memory is the memory/ability to drive a car, to play sports and tie shoes. This type of memory involves repetitive practices. The other of types of memory is Elaboration, Self Referent and Visual Imagery. Elaboration is known as memory associating with other information. Self Referent Memory is how it is made personally relevant. Then, there is Visual Imagery, which can be used in a few ways, one of which can be used to add richness to the material to be remembered.
There are two types of sensory memory: visual and auditory memory. Visual memory is often known as Iconic memory. It plays a huge functioning role in the vision system as it allows the eyes to see continuous and stable pictures. Also, iconic memory allows the brain stem to decide whether the information is important enough to be transferred to the brain. This particular type of memory only lasts a quick second and then it is over. Sterling was known for his studies that helped to understand iconic memory. The most prominent study showed that if he presents a grid of letters using a machine that made the letters appear very quickly, his subject would only remember a few of the letters. The number that was able to be remembered was four to five, and those stayed consistent no matter how many letters appeared on the grid.
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
The five senses of sight, hearing, touch, taste and smell are all sensations throughout the human body. Sensation is the involvement of sensory receptors as well as the central nervous system in order to allow us to experience outside stimuli. The system that allows us to experience sensation is the sensory system.
