Alzheimer’s Impact on Different Memory Types

By Patricia Schumacher, 9:00 am on

The human brain contains billions of neurons that communicate with each other via many different chemical compounds known as neurotransmitters. As adults become older, some of the neurons may shrink or experience damage secondary to free radicals, high blood pressure, or elevated LDL cholesterol. The changes that occur during the aging process may affect the complex memory centers of the brain. However, the neuronal damage that occurs with Alzheimer’s is much more severe, progressive, and extensive. Here are the types of memory Alzheimer’s disease commonly affects.

Short-Term and Long-Term Memory

The process of creating memories requires two steps. Initially, new information enters the hippocampus region of the brain, which is called short-term memory. From there, the information moves to other areas of the brain where the data remains stored until later retrieved, which is long-term memory. Researchers understand the hippocampus is the first region damaged during the development of Alzheimer’s. As such, the region becomes incapable of retaining new information. The hippocampus then has no information or memory to transmit for long-term storage. The damage incurred here is the reason seniors with Alzheimer’s commonly repeat comments, phrases, questions, or conversations. They simply don’t have the ability to remember information from one moment to the next. As Alzheimer’s spreads to other brain areas, other types of memory are affected.

If your loved one has been diagnosed with Alzheimer’s, help is just a phone call away. There are many reasons seniors might need assistance at home. Some may require regular mental stimulation due to an Alzheimer’s diagnosis, while others might only need part-time assistance with exercise and basic household tasks. Home Care Assistance is a leading Rhode Island senior care provider. Families rely on our expertly trained caregivers to help their senior loved ones maintain a high quality of life.

Episodic Memory

Episodic memories take place in the hippocampus, prefrontal cortex, and temporal lobes. While the hippocampus remains responsible for gathering and transferring new information, the other regions keep memories organized as they occur in time. The memories are categorized in a sequence similar to the progression of one television episode to the next. However, when these areas are damaged by Alzheimer’s, the memory timeline becomes skewed, which may be one of the reasons seniors believe older memories happened more recently.

Semantic Memory

Semantic memories also take place in the temporal lobes and multiple regions of the frontal cortex. The memories involve facts and general knowledge. The information stored here includes the names of people, places, and things. The data is also categorized in terms of relationships. Thus, when the regions are damaged, seniors can no longer recall the names of living or inanimate objects in specific categories. They also lose the ability to recognize relationships between people.

Aging adults who need help managing mental and physical health issues can benefit from the assistance of highly trained professional caregivers. Seniors who want to remain healthy as they age can benefit in a variety of ways when they receive professional home care services. Home Care Assistance is here to help your loved one accomplish daily tasks, prevent illness, and focus on living a healthier and more fulfilling life.

Procedural Memory

These memories are formed in the cerebellum and enable people to learn and retain the knowledge and skills needed to perform a particular task automatically. Examples of some of the many procedural memories include riding a bike, dancing, playing an instrument, and typing. This type of memory is typically the last to be affected by Alzheimer’s.

Working Memory

The prefrontal cortex is responsible for working memory, which makes it possible for someone to concentrate, pay attention, and form short-term memories. Working memory enables seniors to complete tasks that require multiple steps. However, when this type of memory is damaged by Alzheimer’s, older adults are no longer able to complete lengthy tasks without guidance.

If you’re the primary caregiver for a loved one with Alzheimer’s disease, you don’t have to go through it alone. Without the right assistance, Alzheimer’s can be challenging for seniors and their families to manage.
