Memory Loss in Alzheimer's: Causes, Symptoms, and Treatment
What is Memory Loss in Alzheimer's?
It is a brain disorder that causes a gradual loss of memory, reasoning, learning, and organizational abilities. It eventually impacts a person's ability to perform essential daily tasks. Alzheimer's disease (AD) is the leading cause of dementia. The condition of a person's mental function is referred to as dementia. It is not a particular disease. This condition is a deterioration in cognitive function from a previously higher level that is severe enough to interfere with daily functioning (also known as dementia). Alzheimer's symptoms develop with time.
Alzheimer's disease is most prevalent in elderly adults, with early-onset cases occurring in their 40s or 50s, accounting for less than 10% of all cases and increasing the likelihood of developing the condition.

Get A Second OpinionWhat Are the Stages of Alzheimers Disease?
Alzheimer's disease affects individuals differently, with timing and severity varying from person to person.
- Prior to the Appearance of Symptoms : Alzheimer's disease alterations in the brain begin ten to fifteen years before symptoms appear, known as "pre-clinical Alzheimer's disease." Currently, no treatment exists for this stage, but there is hope for future drugs to prevent progression. Regular visits to primary care providers are crucial for detecting early signs of Alzheimer's disease, as the risk increases with age. If cognitive abilities decline, it may indicate that your loved one is entering the second stage of the disease. Regular screenings are essential to prevent the disease from recurring.
- Basic forgetfulness : It is the second stage of Alzheimer's disease, which can appear normal as one age. Despite memory lapses, such as forgetting names or keys, a loved one can still drive, work, and interact. These lapses are more frequent and may be noticed before they occur.
- Memory Problems That Are Clearly Observable : During this stage, people experience visible changes and may struggle with daily activities, leading to a diagnosis. Challenges include forgetting names, losing things, and needing help recalling recent material. Those affected may experience social or work challenges, increased anxiety, and deny the issue.
- More Than Just Memory Loss : Brain injury can lead to cognitive issues such as language, organization, and mathematics difficulties, making daily activities difficult. During this stage, the person may still remember essential aspects of their life, but their memory of the distant past is stronger. Other challenges include:
- Confusion.
- Increased risk of getting lost.
- Changes in sleep patterns.
- Choosing appropriate attire.
- Difficulty thinking in situations.
Personality changes may also occur, such as feeling suspicious, less interested, or depressed.
- Decreased independence : Until this point, the person has lived independently without significant challenges. They may struggle with remembering family and friends, learning new things, and managing basic tasks. Emotional shifts, such as hallucinations, delusions, and paranoia, are standard during this stage, including difficulty remembering essential people, learning new things, and dealing with basic activities.
- Extremely Severe Effects : Living independently can be challenging, especially for those in the sixth stage of Alzheimer's disease. This stage can lead to more significant symptoms, affecting their ability to manage their care and dependence on others. Communication may become more complex, and significant personality changes may occur, such as heightened anxiety, hallucinations, delusions, and paranoia. It's crucial to discuss behavioural tactics and medications with the care team to help manage these situations. While not all patients may experience these changes, it's important to remember that they are not conscious of their situation.
- Lack of physical control : Alzheimer's disease is a brain disorder causing significant mental and physical disability. It can lead to decreased communication and role distribution, requiring assistance with walking, sitting, and swallowing. As a result, they are more susceptible to illnesses like pneumonia. Preventing infections involves maintaining cleanliness, treating cuts and scratches, and getting annual flu shots.
What Are the Causes for Memory Loss in Alzheimer’s?
Alzheimer's disease is caused by abnormal protein accumulation in the brain, specifically amyloid and tau proteins. These proteins cause the death of brain cells, affecting communication and thinking processes.
Plaques and tangles form when amyloid protein accumulates, while tau twisted fibres cause tau tangles. The disease's symptoms occur gradually and persistently, often starting in the hippocampus and spreading to other brain regions.
The cause of Alzheimer's is still unknown, but it is hypothesized to be a combination of genetics, environment, and lifestyle choices. Research is ongoing to understand the exact cause.
Treatments for Memory Loss in Alzheimer’s:
Although there is currently no treatment for Alzheimer's disease, there are drugs that can temporarily reduce the progression of dementia symptoms from one person to the next. When dealing with Alzheimer's disease, beginning treatment as soon as possible could be beneficial in maintaining everyday functioning for some time. However, the drugs that are currently available cannot stop or reverse Alzheimer's disease. Two categories of medications have been approved:
- Cholinesterase inhibitors are medications:
- Donepezil (Aricept®). This is also FDA-approved to treat moderate to severe AD.
- Rivastigmine (Exelon®).
- Galantamine (Razadyne®).
- Drugs block acetylcholinesterase, causing Alzheimer's symptoms. Acetylcholine is crucial for nerve cell communication. They improve memory and reduce behavioural issues but don't cure or stop the disease's progression.
- NMDA antagonists are substances: Memantine
- Aducanumab (AduhelmTM) is the first disease-modifying medication for Alzheimer's disease. Taking this drug will reduce amyloid deposits in the brain.
- To manage changes in behaviour in Alzheimer's patients, maintain their familiar environment and provide comfort through comfort items, distractions, and avoidance of confrontation. Currently, no approved medication is available for treating behavioural problems associated with Alzheimer's disease. However, some drugs, such as antidepressants, anti-anxiety medications, anticonvulsants, and neuroleptics, can be prescribed for severe symptoms.
- Clinical trials are ongoing to find treatments for Alzheimer's disease. The accumulation of amyloid and tau proteins in the brain leads to the death of brain cells. Plaques and tangles form when amyloid protein accumulates, preventing nerve cells from functioning. The gradual and persistent death of nerve cells and fibres causes the signs and symptoms of Alzheimer's disease.

Short-term memory loss is often the initial symptom of Alzheimer's disease, and as the disease progresses, it gradually progresses to damage long-term memory.
The formation of aberrant protein deposits in the brain, notably beta-amyloid plaques and tau tangles is the primary cause of memory loss in Alzheimer's disease. These deposits impede communication between brain cells, which ultimately results in the death of those cells.
Even though it is not very frequent, some people who have Alzheimer's disease may first suffer symptoms that are not characteristic of the disease. These symptoms may include changes in behaviour, issues with language, or poor executive function. This may occur before memory loss becomes noticeable. Memory loss, on the other hand, is a hallmark sign of Alzheimer's disease, and it is present in the majority of cases at some point.
Cognitive function, memory, judgment, and behaviour can all be negatively impacted by Alzheimer's disease, which can significantly influence day-to-day life. This may result in difficulties with responsibilities such as managing funds, keeping personal cleanliness, remembering appointments, and following discussions. Alzheimer's disease can also affect a person's personality and demeanour, leading to symptoms such as agitation, despair, or apathy.
One of the most prominent characteristics of the final stage of Alzheimer's disease, which is frequently referred to as severe or late-stage Alzheimer's, is a significant deterioration in both cognitive and physical function. There is a possibility that individuals will lose the ability to converse transparently, recognize loved ones, or carry out fundamental activities of daily living. Another possibility is that they could have difficulties, such as infections or difficulty eating, which would finally result in their passing.
Despite the fact that stress does not directly cause Alzheimer's disease, persistent stress can make symptoms worse and speed up cognitive deterioration in people who are already living with the condition. One way to lessen the influence that stress has on the advancement of Alzheimer's disease is to learn how to manage it through relaxation techniques, social support, and practising healthy lifestyle practices.
