Memory is the ability to remember, store and recall information, divided into categories such as sensory, motor, short-term, and long-term.
Memory is an indispensable part of life, helping us shape our perceptions and interactions. Memory is a complex process, involving many parts of the brain. 4 types of human memory such as sensory, short-term, working (active) and long-term.
Sensory memory
Sensory memory is a very brief, about three-second recollection of a sensory experience such as what we just saw or heard. For example, sensory memory with a snapshot, you often remember what you just experienced and then this memory will quickly disappear.
Short term memory
Short-term memory is the short period of time in which you can recall information you have just been exposed to. Short-term memories usually last from 30 seconds to several days, depending on the person.
One of the most common early symptoms of Alzheimer's disease is short-term memory loss. When talking about Alzheimer's disease, clinicians often use the term "short-term memory loss" to refer to memory loss of short periods of time. It includes memories of about 30 seconds and memories lasting up to several days. This type of short-term memory loss is often one of the first signs that a person's cognitive function is declining.
People with early signs of Alzheimer's disease may repeat questions frequently over several hours or tell the same story they told five minutes ago.
Working memory
Working memory is defined as the brain's ability to retain a certain amount of information long enough to use it. Working memory helps process thoughts and plans as well as carry out ideas.
Working memory is also considered short-term memory that combines strategies and knowledge from the long-term memory bank to support decision making or calculations in tasks.
Working memory is related to executive function, which is often affected in the early stages of Alzheimer's disease.
Long-term memory
Long-term memory includes memories that last from a few days to decades. For learning, working, and storing information to be successful, information is transferred by the brain from sensory memory or short-term memory to long-term memory.
The long-term memories of people with early-stage Alzheimer's disease often remain intact. As Alzheimer's disease progresses to the middle and late stages, long-term memory is also affected. For example, a person with advanced Alzheimer's disease may not remember that his mother passed away 20 years ago.
In the later stages of Alzheimer's disease, people often have difficulty recognizing people they have known for many years, such as close friends or family members.
In the early and even middle stages of Alzheimer's, people can still learn something if it is repeated regularly. However, as Alzheimer's disease progresses to its final stages, the ability to access old memories and form new ones is lost.
